       The following symbols and signal words call your attention to instructions concerning your
       personal safety. Be sure to observe and follow these instructions.
         NOTE: ONLY safety instructions regarding personal injury are listed in this section. Cau-
         tion statements regarding only equipment damage appear where applicable throughout
         the manual.
                Only persons who have read and understood the entire operator's
                manual should operate the sawmill. The sawmill is not intended for
                use by or around children.
               DANGER! Maintain a clean and clear path for all necessary move-
               ment around the mill and lumber stacking areas. Failure to do so
               will result in serious injury.
              WARNING! Use ONLY water with the water lube accessory. Never
              use flammable fuels or liquids. If these types of liquids are neces-
              sary to clean the blade, remove it and clean with a rag. Failure to
              do so may result in serious injury or death.

              WARNING! Keep all persons out of the area between the frame
              rails while loading and unloading the sawmill. Failure to do so may
              result in serious injury or death.
              WARNING! Because the sawmill can easily rotate and tip over
              when lifted, do not lift the sawmill using ropes, cables or chains,
              etc. Doing so may result in machine damage, serious injury or
              death.
               DANGER! Make sure all guards and covers are in place and
               secured before operating or towing the sawmill. Failure to do so
               may result in serious injury.
               Be sure the blade housing and pulley covers are in place and
               secure. Use the safety retainer pin and cable to fasten blade hous-
               ing covers.
             DANGER! Always disengage the blade and shut off the sawmill
             engine before changing the blade. Failure to do so will result in
             serious injury.
             WARNING! Do not for any reason adjust the engine drive belt with
             the engine running. Doing so may result in serious injury.

         Lockout procedures must be followed (see ANSI Standard Z244.1-1982 and OSHA regu-
         lation 1910.147).
Purpose:
         This procedure establishes the minimum requirements for lockout of energy sources that
         could cause injury.
Responsibility:
         The responsibility for seeing that this procedure is followed is binding upon all workers. All
         workers shall be instructed in the safety significance of the lockout procedure. It is your
         responsibility to ensure safe operation of the machine.
Sawmill must be locked out both electrically and pneumatically (lockout air valve).
1. Notify all persons that a lockout is required and the reason therefore.
    3. Operate the switch and valve so that the energy sources are disconnected or isolated
       from the Sawmill. Stored energy such as moving blades, feed system and air pressure
       shall be dissipated.
    5. After ensuring that no persons are exposed and as a check on having disconnected the
       energy sources, operate the push button or other normal operating controls to make cer-
       tain the Sawmill will not operate. Caution: Return operating controls to neutral position
       after the test.
   1. When the job is complete and the Sawmill is ready for testing or normal service, check
      the Sawmill area to see that no one is exposed.
   2. When the Sawmill is all clear, remove all locks. The energy isolating devices may be
      operated to restore energy to the Sawmill.
        In the preceding steps, if more than one individual is required to lock out the Sawmill,
        each shall place his own personal lock on the energy isolating devices.
        The Sawmill shall be locked out to protect against accidental or inadvertent operation
        when such operation could cause injury to personnel. Do not attempt to operate any
        switch or valve bearing a lock.
Owner’s Responsibility
        The procedures listed in this manual may not include all ANSI, OSHA, or locally required
        safety procedures. It is the owner/operator’s responsibility and not Wood-Mizer Products
        to ensure all operators are properly trained and informed of all safety protocols.
        Owner/Operators are responsible for following all safety procedures when operating and
        performing maintenance to the Sawmill.
              IMPORTANT! Always be sure that all safety decals are clean and
              readable. Replace all damaged safety decals to prevent personal
              injury or damage to the equipment. Contact your local distributor,
              or call your Customer Service Representative to order more
              decals.
                WARNING! Always secure the saw head with a 5/16" chain with at
                least 1900 lbs. working load capacity before adjusting the up/down
                chain. The saw head may fall, causing severe injury or death.
                WARNING! Always secure the saw head with a 5/16" chain with at
                least 1900 lbs. working load capacity before adjusting the mast
                pads. The saw head may fall, causing severe injury or death.
       NOTE: The following setup procedure should be performed whenever the sawmill is
       moved or reassembled. If sawing problems occur and misalignment is suspected, See
       Section 7 for complete alignment instructions. See Section 8 for sawmill assembly
       instructions.
   1. Adjust the frame legs so the sawmill appears level. If sawmill is on soft ground, use shims
      under the legs if necessary.
   2. Run a string from the front bed rail to the rear bed rail near the operator’s side of the
      frame. Place identical spacers between the string and the front and rear bed rails. Mea-
      sure the distance between the string and the other bed rails. Adjust the frame legs until all
      bed rails measure the same distance from the string.
   3. Loosen the auxiliary bed rail bolts and adjust the rail so it is the same distance from the
      string as the main bed rails. Retighten the bolts.

      5. Install a blade (See Section 3.2 through Section 3.2) and move the saw carriage until the
         blade is positioned over the front bed rail.
      6. Measure the distance from the bed rail to the bottom of the blade near the inside blade
         guide.
      7. Measure the distance from the bed rail to the bottom of the blade near the outside blade
         guide.
         See Figure 3-2. When the blade is parallel to the bed, it will measure the same distance
         from the bed rail at the inside and outside of the saw head. The up/down slide pads have
         two sets of four adjustment spacers that allow you to tilt the saw head up or down. Turn
         the saw head adjustment spacers in 1/4-turn increments to move the outside of the saw
         head up or down.

       Open the two blade housing covers that cover the blade wheels. Turn the blade tension
       handle to release the blade tension until the wheel is pulled in and the blade is lying loose
       in the blade housing. Lift the blade out of the blade housing.
       When installing a blade, make sure the teeth are pointing the correct direction. The teeth
       should be pointing toward the operator side of the mill when you are looking at the blade
       below the blade guides. Install the blade so it is lying around the wheels.
       Position 1 1/4” wide blades on the wheels so the gullet is 1/8" (3.0 mm) out from the edge
       of the wheel.Close the blade housing covers.
Next, turn the tension handle until the blade is tensioned correctly.
       See Figure 3-4. The blade tensioner is factory-set so proper blade tension is achieved
       when the rubber spring is compressed 3/16” (4.8 mm). A 3/16” washer is provided to indi-
       cate when the rubber spring has been compressed properly. To tension the blade, turn
       the blade tension handle clockwise to compress the rubber spring until the indicator
       bracket is even with the outside face of the washer. Check the blade tension occasionally
       when adjusting the cant control or while cutting. As the blade and belts heat up and
       stretch, the blade tension will change. Adjust the tension handle as necessary to keep the
       bushing aligned with the indicator.

       necessary.
   1. Make sure the blade housing covers are closed and all persons are clear of the open side
      of the saw head.
3. Engage the blade, rotating the blade until the blade positions itself on the wheels.
   4. Disengage the blade. Turn off the engine, remove the key and check the position of the
      blade on the blade wheels.
       See Figure 3-5. Position 1 1/4” wide blades so the gullet is 1/8" (3.0 mm) out from the
       edge of the blade wheel (±1/32 [.75 mm]).

       Sawmill Operation
 4 Loading, Turning And Clamping Logs
SECTION 4 SAWMILL OPERATION
4.1      Loading, Turning And Clamping Logs
To Load Logs
      2. Adjust the log clamps all the way down and move them toward the loading side of the
         sawmill frame. NOTE (Rev. D6.00 Only): The clamps can be lifted and removed from the
         bracket assemblies to avoid damage to the clamp when loading a log.
      3. Raise the side supports on the sawmill bed to prevent the log from falling off the side of
         the bed.
      4. Place the optional loading ramps in the frame brackets that will evenly support the length
         of the log.
150019
FIG. 4-1
    6. Use a cant hook to roll the log up the ramps and onto the sawmill bed. Position the log
       against the side supports.
        If you did not purchase the optional loading ramps, use boards for ramps or use log load-
        ing equipment to load the log on the sawmill bed.
        NOTE: Logs also may be loaded onto the mill with a tractor or other equipment specifi-
        cally designed for that purpose.
To Turn Logs
2. Spin the log against the side supports until it is turned the way you want it for the first cut.
    1. Rev. E3.02+ Only: Press down on the clamp upright lock and adjust the upright up or
       down as necessary. Slide the clamp against the log and turn the locking handle to lock
       the clamp against the log.
150089-4
        Rev. A1.00 - E3.01 Only: Position the clamps against the log, far enough down so they
        are below your first few cuts. Turn the clamp screws (Rev. A1.00 - D5.00) or pivot the
        clamp handle (Rev. D6.00 - E3.01) to clamp the log firmly against the side supports.
150089-1B
150022
Use shims or the optional wedge to raise either end of a tapered log, if desired.
        Shim one end of the log until the heart of the log measures the same distance from the
        bed rails at each end of the log.
                                                                     Leveling
                                                                     wedge

1. Install a blade, if needed, and check for correct blade tension. (See Section 3.2).
      2. Set the cutting head to the desired height. (The blade height scale shows the height of the
         blade above the bed rails.)
See Figure 4-5. Use the up/down crank to raise or lower the cutting head.

    3. Rev. A.00 - A.01: Turn the up/down lock counterclockwise until it disengages the
       up/down shaft. Rev. B.00+: Pull the up/down lock out and rotate until the roll pin handle
       locks in the out position.
4. Pull back on the crank handle to engage the locking pins for up/down operation.
    5. Turn the up/down crank clockwise to raise the saw head, counterclockwise to lower the
       saw head.
    6. Rev. A.00 - A.01: Turn the up/down lock clockwise until it engages the up/down shaft.
       Rev. B.00+: Rotate the up/down lock to allow the spring-loaded pin to engage the
       up/down sprocket.
      1. Look down the length of the log to see its maximum width. The outer blade guide should
         be adjusted to clear the widest section of the log by less than 1" (25.4 mm).
      2. Use the blade guide arm knob to adjust the outer blade guide as necessary. Turn the
         blade guide arm knob clockwise to move the arm in. Turn the knob counterclockwise to
         move the arm out.
150025B
FIG. 4-6
1. Clear any loose objects from the area of the blade, motor, and drive belt.
    2. Make sure the clamps and side supports are adjusted below the level of your first few
       cuts.
        Be sure the blade housing and pulley covers are in place and secure before starting the
        engine or motor. Use the rubber latches to fasten the blade housing covers shut.
See Figure 4-7. The clutch lever is located next to the engine.
                    150079-2
                                                                              FIG. 4-7 D4.00 - D7.00
150026
   4. To engage the blade, pull the clutch lever clockwise until it locks in the down position. This
      engages the drive mechanism and increases the engine speed to full throttle.
   5. To disengage the blade, raise the clutch lever to the up position. This disengages the
      drive belt and returns the engine to idle.
    1. To move the carriage forward, push the crank handle in to engage the screw heads and
       rotate the feed crank clockwise.
150027
FIG. 4-8
        HINT: To get a straight cut in the first part of the board, feed the blade into the log at a
        slow speed. This stops the blade from flexing and dipping up or down. Use a slow speed
        until the whole width of the blade has entered the cut. Then increase the feed rate as
        desired. Maximum feed rate varies with width and hardness of the wood. Over-feeding
        results in engine and blade wear, and also produces a wavy cut.
    2. Stop the carriage at the end of the cut. Throw the clutch lever up to stop the blade and
       drop the engine to idle. Remove the board from the top of the log. Always disengage the
       blade before returning the carriage for the next cut.
    3. CAUTION! Be sure to stop the blade when returning the carriage. This will not only pre-
       vent the blade from being pulled off and ruined by a wood sliver, but also will increase the
       life of the blade.Make sure that the blade does not catch on the end of the log. Raise the
       carriage slightly to make sure the blade clears the log when returned.
        HINT: Try to stop the blade while the heel of the blade is still on the log. Then bring the
        carriage back without adjusting the blade up. This lets you keep the blade at the current
        height setting so you can make the next blade height adjustment more quickly.
The following steps guide you through normal operation of the Wood-Mizer sawmill.
    1. Once the log is placed where you want it and clamped firmly, position the blade close to
       the end of the log.
    2. Use the blade height scale to determine where to make your first cut (See Section 4.8).
       The blade height scale will help you to do this. Set the blade to the desired height with the
       up/down crank. Make sure that the blade will clear all side supports and the clamps.
       Adjust the outer blade guide to clear the widest section of the log by moving the blade
       guide arm knob.
    3. Make sure all covers and guards are in place. Start the engine. Engage the clutchlever to
       start the blade spinning.
4. Start the water lube if necessary to prevent sap buildup on the blade. See Section 4.9.
    5. Feed the blade into the log slowly (See Section 4.5). Once the blade completely enters
       the log, increase the feed rate as desired. Always try to cut at the fastest speed you can
       while keeping an accurate cut. Cutting too slowly will waste blade life and lower produc-
       tion!
    6. As you get to the end of the log, slow down the feed rate. When the teeth exit the end of
       the log, Disengage the clutch/brake lever. Remove the slab that you have just cut from
       the log.
7. Use the feed crankto return the carriage to the front of the mill.
    8. Repeat until the first side of the log is cut as desired. Set aside the usable flitches (boards
       with bark on one or both sides). You can edge them on the mill later.
   10. Repeat the steps used to cut the first side of the log until the log is square. Cut boards
       from the remaining cant by adjusting the blade height for the thickness of boards that you
       want.
        Example: Remember that the blade cuts a 1/16 - 1/8" (1.6-3.2 mm) wide kerf. If you want
        1" (25.4 mm) thick boards, lower the carriage 1 1/16 - 1 1/8" (27-28.6 mm) for each board.
The following steps guide you through edging boards on the Wood-Mizer sawmill.
    1. Raise the side supports to 1/2 the height of the flitches, or the boards that need to be
       edged.
    3. Clamp the flitches against the side supports halfway up the flitch height. (Wider flitches
       should be placed to the clamp side. When they are edged, flip them over to edge the sec-
       ond side without disturbing the other flitches or without having to pull them from the mid-
       dle of the stack).
5. Loosen the clamps and turn the edged boards over to edge the other side.
    7. Loosen the clamps and remove the boards that have good clean edges on both sides.
       Clamp the remaining flitches and repeat steps 2-5.
        See Figure 4-9. The blade height scale is attached to the carriage head frame. It
        includes:
 an inch scale
                                                                     Inch Scale
                              Blade
                              Height
                              Indicator
150028
FIG. 4-9
        The horizontal line on the blade height indicator shows how many inches the bottom of
        the blade is above the bed of the mill. If you know the height of your blade at each cut,
        you can determine the thickness of lumber you are sawing.
        Example: You want to cut 1" (25 mm) random width boards from a log. Position the blade
        for the first cut. Move the carriage to an even measurement on the inch scale. Make a
        trim cut. Return the carriage for the second cut and lower it 1 1/8" (29 mm) below the orig-
        inal measurement. (The extra 1/8" (3 mm) allows for saw kerf and shrinkage of the lum-
        ber.)
        The yellow area on the scale identifies where the blade could encounter a side support or
        log clamp. Check that these items are below the blade level before sawing.
        See Table 4-1. The magnetic quarter scale has four sets of marks. Each set represents
        a specific lumber thickness. Saw kerf and shrinkage allowance are included, but actual
        board thickness will vary slightly depending on blade thickness and tooth set.
        Position the magnetic quarter scale over the inch scale. Align one of the quarter scale
        marks with the horizontal line on the indicator.
        Make a trim cut. When you return the carriage for a second cut, lower the carriage to the
        next mark on the scale. This mark shows where the blade should be positioned to cut a
        certain thickness of lumber, without having to measure on the inch scale.
        Example: You want to cut 1" (25 mm) (4/4) random width boards from a log. Position the
        blade for the first cut. Position the magnetic quarter scale so a 4/4 mark is aligned with
        the line on the indicator. Make a trim cut. Return the carriage for the second cut. Now,
        instead of having to measure down 1 1/8" (29 mm) on the inch scale, you can simply
        lower the blade so the indicator is aligned with the next 4/4 mark on the quarter scale.
        Turn the log 90 degrees and repeat.
        The optional Water Lube System keeps the blade clean. Water flows from a 5-gallon
        (18.9 liter) bottle through a hose to the blade guide where the blade enters the log. A
        valve in the bottle cap controls the amount of water flow.
See Figure 4-10. Install the water bottle bracket at the top of the saw head mast.
                                                          Place bottle
                                                          assembly in
                                                          bracket
                                                                           Connect hose
                                                                           to blade guide
                                                                           tube
150029

FIG. 4-11
        Not all types of wood require the use of the Water Lube System. When it is needed, use
        just enough water to keep the blade clean. This saves water, and lowers the risk of stain-
        ing the boards with water. Usual flow will be 1-2 gallons (3.8-7.6 liters) per hour.
        Before removing the blade, engage the blade. Let the blade spin with water running on it
        for about 15 seconds. This will clean the blade of sap buildup. Wipe the blade dry with a
        rag before storing or sharpening.
        For further lubrication benefits, add one 12oz. bottle of Wood-Mizer Lube Additive to 5
        gallons of water. Wood-Mizer Lube Additive enables some previously impossible timbers
        to be cut by significantly reducing resin buildup on the blade. It helps to reduce heat
        buildup, wavy cuts, and blade noise. This biodegradable and environmentally friendly
        pre-mix includes a water softener additive, so it works with hard water.
        If you are sawing in freezing temperatures, remove the water lube bottle from the sawmill
        when done sawing and store it in a warm place. Blow any remaining water from the water
        lube hose.
        The assembled sawmill can be manually loaded into and transported in an appropriately
        equipped pickup truck:
1. Remove the leg assemblies or adjust them above the bottom of the bed frame.
        See Figure 4-12. See Section 8.7 for a detailed description of carriage lock pin opera-
        tion.
150082-1
150082-3
   2. Adjust the saw head up just far enough so it will clear the sides of your truck bed when
      loaded. For most pickup trucks, a minimum of 18” between the blade and bed frame
      cross members should be adequate. Do not adjust the saw head so high that the sawmill
      will tip easily while being loaded.
   3. Move the carriage to one end of the mill. Rotate and release the lock pin closest to the
      end of the mill. Be sure the lock pin engages the hole in the bed frame to secure the saw
      carriage in place. Check the other lock pin remains in the operation position.
   4. To eliminate the possibility of damage and/or injury, remove the tailgate from your truck
      and set it aside.
5. Position the bed of the truck at the end of the frame opposite the carriage.
    7. With a person positioned on either side of the saw head, pull and rotate the lock pin from
       the travel position to the operation position. More people may be required to help push as
       the saw head gets more difficult to push up the incline. Push the saw carriage up the bed
       frame and have a third person engage the lock pin at the end of the sawmill to secure the
       carriage to the hole in the bed frame. Be sure to leave the other lock pin in the operation
       position.
    8. Use three or more people to lift the end of the mill still on the ground and slide the sawmill
       into the truck bed.
    9. Secure the sawmill to the truck bed to prevent the sawmill from shifting while it is being
       transported. If the sawmill extends beyond the truck bed, attach a red warning flag to the
       end of the sawmill.
           See the Maintenance Log located after this section for a complete list of maintenance
           procedures and intervals. Keep track of machine maintenance by filling in the machine
           hours and the date you perform each procedure.
           This symbol identifies the interval (hours of operation) at which each maintenance pro-
      0    cedure should be performed.
Be sure to refer to option and engine manuals for other maintenance procedures.
           See Table 5-1. This chart lists estimated life expectancy of common replacement parts if
           proper maintenance and operation procedures are followed. Due to the many variables
           which exist during sawmill operation, actual part life may vary significantly. This informa-
           tion is provided so that you may plan ahead in ordering replacement parts.
    1. For mills equipped with greaseable blade guides, lubricate the blade guide rollers every
   4   four hours of operation. Use one squeeze of a NLGI No. 2 grade lithium grease from a
       grease gun to lubricate the bearings and remove any sawdust.
                    Grease blade
                   guide rollers (2)
SM0052B
FIG. 5-1
   2. Check the rollers for performance and wear every blade change. Make sure the rollers
      are clean and spinning freely. If not, replace them. Replace any rollers which have worn
      smooth or have become cone shaped.
        Remove the excess sawdust from the blade wheel housings and sawdust chute every
  AR    blade change.
        Remove sawdust buildup from rope feed pulleys and up/down chain sprockets as neces-
        sary.
       Properly maintaining the sawmill carriage track is critical in preventing corrosion that can
       cause pitting and scaling on the rail surfaces. Pitted and scaled surfaces can, in turn,
       cause rough cuts or jerky feed movement.
   1. Clean track rails to remove any sawdust and sap buildup every eight hours of operation.
   8
       Use a light-grade sandpaper or emery cloth to sand off any rust or other adhering parti-
       cles from the rails.
       Lubricate the rails by wiping them with Dexron III ATF transmission fluid. Lubrication will
       help protect the rails from corrosive elements such as acid rain and/or moisture from
       nearby bodies of saltwater (if applicable). This lubrication is essential to maintain the
       integrity of the track rails and track rollers and to achieve long service life.
   2. Remove sawdust from the track roller housings and lubricate the felt track wipers every
  25  twenty-five hours of operation.
       Remove the track roller housing covers and brush any sawdust buildup from the hous-
       ings.
       Rev. B+ only: Clean and lubricate the felt track wipers. Unbolt the middle track cover and
       idle track wipers, remove from the sawmill and remove any sawdust buildup. Soak the felt
       wipers with Dexron III transmission fluid.
150030B
FIG. 5-2
       Clean and lubricate the vertical mast rails every 50 hours of operation. Clean with solvent
  50   and remove any rust with a light-grade sand paper or emery cloth. Lubricate the mast with
       motor oil or automatic transmission fluid (ATF).
       1. Oil all chains with Dexron III ATF every fifty hours of operation.
      50
       2. Grease the clamps and side support pivots with a NLGI No. 2 grade lithium grease every
      50  fifty hours of operation.
       4. Lubricate the tensioner screw threads with a NLGI No. 2 grade lithium grease as needed.

       5. Make sure all safety warning decals are readable. Remove sawdust and dirt. Replace any
          damaged or unreadable decals immediately. Order decals from your Customer Service
          Representative.
       Rotate the blade wheel belts and check them for wear. Rotating the belts every 50 hours
  50   will provide longer belt life. Replace belts as necessary. Use only B57 belts manufactured
       by Goodyear or Browning.
       See Figure 5-4. As the brake pads wear, the engine will drop further down when the
       clutch handle is disengaged. This may cause the drive belt to vibrate out of the engine
       pulley when disengaged. To avoid this, turn the brake adjustment bolt counterclockwise to
       prevent the engine from dropping too low. When the bolt cannot be adjusted any further,
       replace the brake pads.

   2. After tensioning the drive belt, check throttle cable tension and adjust if necessary. Make
      sure that the throttle linkage is not affecting the engine RPM while the clutch/brake handle
      is disengaged. Make sure the cable is not bent or kinked. The throttle cable should be
      tensioned just enough so that the engine revs as soon as the clutch/brake handle is
      engaged. NOTE: A properly adjusted throttle will extend the cable spring 1/4" to 3/8"
      (6.4 - 9.5 mm) when running and have a slight amount of slack in the cable when idling.

Blade Installation
      1. Remove the blade and check the blade wheel belts. Remove any sawdust buildup from
         the surface of the belts. Replace worn belts if they do not keep the blade from contacting
         the blade wheel.
2. Install a clean blade and apply the appropriate tension (See Section 3.3).
3. Adjust the idle-side cant control to track the blade (See Section 3.4).
4. Close the blade housing cover and make sure all persons are clear of the saw head.
6. Engage the blade, rotating the blade until the blade positions itself on the wheels.
       The blade guide arm moves the outer blade guide in and out. If the arm becomes loose,
       the blade guide will not deflect the blade properly, causing inaccurate cuts. A loose blade
       guide arm can also cause blade vibration.
1. Adjust the blade guide arm in to 1/2" (15 mm) from fully closed.
       See Figure 7-1. Use the inside top and bottom screws to adjust the arm up until the slide
       pad touches the saw head brace tube. Tighten the jam nuts.
150035
FIG. 7-1
2. Adjust the blade guide arm in all the way toward the other blade guide.
   3. Use the outside top and bottom screws to adjust the arm up until the slide pad touches
      the saw head brace tube. Tighten the jam nuts.
FIG. 7-2
      4. Measure the distance between the blade guide arm and back edge of the blade. Adjust
         the appropriate side screws on the blade guide arm housing so the arm is measures the
         same distance from the blade at both ends of the arm.
      5. To move the blade guide end of the arm toward the front of the sawmill, loosen jam nuts
         on the front inside screw and the rear outside screw. Turn the screws counterclockwise
         one full turn and tighten the jam nuts. Loosen the jam nuts on the front outside screw and
         the rear inside screw. Turn the screws clockwise until they touch the arm, back off 1/4”
         turn, and tighten the jam nuts.
      6. To move the blade guide end of the arm toward the rear of the sawmill, loosen jam nuts
         on the front outside screw and the rear inside screw. Turn the screws counterclockwise
         one full turn and tighten the jam nuts. Loosen the jam nuts on the front inside screw and
         the rear outside screw. Turn the screws clockwise until they touch the arm, back off 1/4”
         turn, and tighten the jam nuts.
       The blade guides should be adjusted properly in the vertical plane. If the blade guides are
       tilted vertically, the blade will try to travel in the tilted direction.
       A Blade Guide Alignment Tool (BGAT) is provided to help you measure the vertical tilt of
       the blade.
1. Open the adjustable blade guide arm 1/2" (15 mm) from full open.
   2. Clip the alignment tool on the blade. Position the tool close to the outer blade guide
      assembly. Be sure the tool does not rest on a tooth or burr, and is lying flat against the
      bottom of the blade.

   3. Move the carriage so that the front end of the tool is positioned above the bed rail. Mea-
      sure the distance from the bed rail to the bottom edge of the tool.
   4. Move the carriage so that the back end of the tool is positioned above the bed rail. Mea-
      sure the distance from the bed rail to the bottom edge of the tool.
   5. If the measurement from the tool to the bed rail is not equal within 1/32" (.75 mm), adjust
      the vertical tilt of the outer blade guide roller.
6. Loosen one set screw at the side of the blade guide assembly.
                                                                                                    FIG. 7-4
      7. Move the blade guide alignment tool close to the inner blade guide roller assembly and
         repeat the above steps. Adjust the vertical tilt of the inner blade guide if necessary.
       If the blade guides are tilted in the wrong direction horizontally, the back of the blade may
       contact the flange as the roller is spinning down, causing it to push the blade away from
       the guide roller.
   8. Remove the blade guide alignment tool from the blade and adjust the blade guide arm
      halfway in.
   9. Remove the clip from the blade guide alignment tool. Place the tool against the face of
      the outer blade guide roller.

      12. Repeat the above steps for the inner blade guide roller assembly.
       Each blade guide must be adjusted so the roller flange is the correct distance from the
       back edge of the blade. If the flange is too close to or too far from the blade, the sawmill
       will not cut accurately.
   1. Measure the distance between the flange on the inner blade guide roller to the back edge
      of the blade. This distance should measure 1/16" (1.5 mm). Adjust the roller back or for-
      ward if necessary.
       See Figure 7-7. Loosen the top and one side screw shown. Tap the blade guide forward
       or backward until properly positioned. Retighten the screws and jam nuts.
                                                                                           FIG. 7-7
   2. Measure the distance between the flange on the outer blade guide roller to the back edge
      of the blade. This distance should measure 1/8" (3.0 mm). Adjust the roller back or for-
      ward if necessary.
         Logs and boards are clamped against the side supports when sawing. The sides supports
         must be square to the bed to ensure square lumber.
      1. Swing a side support down and measure between the face of the support and the main
         bed tube. The distance at the top of the side support (’B’) should be equal to or no more
         than 1/32" (0.8 mm) greater than the distance at the base of the side support (’A’). Adjust
         the horizontal tilt of the side support if necessary.
         See Figure 7-8. Loosen the two adjustment plate mounting bolts. Use a mallet to move
         the plate until the side support is parallel to the bed tube in the horizontal position.
         Retighten the mounting bolts.

2. Repeat the horizontal check for the remaining side supports. Adjust as necessary.
      3. Place square alignment tubes (Part No. S12831 - 2 required) across the bed rails. Swing
         a side support up so that it is vertical.
      4. Pull back at the top of the support to eliminate slack as if a log were being clamped
         against it.
      5. Place a square against the face of the side support. The side support should be square or
         slightly tilted forward 1/32" (0.8 mm). Adjust the vertical tilt of the side support if neces-
         sary.
                                                                                 Side Support

150039
FIG. 7-9
6. Repeat the vertical check for the remaining side supports and adjust as necessary.
        After the entire sawmill has been aligned and all adjustments made, check that the blade
        height scale indicates the true distance from the blade to the bed rails.
   1. Move the saw head so the blade is positioned directly above one of the bed rails. Mea-
      sure from the bottom edge on a down-set tooth of the blade to the top of the bed rail, near
      the inner blade guide assembly.
   2. View the blade height scale with eyes level with the indicator. The scale should indicate
      the actual distance from the blade to the bed rail. Adjust the indicator if necessary.
        See Figure 7-10. Loosen the indicator bracket mounting bolts and adjust the bracket until
        the indicator is aligned with the correct mark on the scale (+0 -1/32 [0.8 mm]). Retighten
        the bracket mounting nut.
        For example, if the measurement from the down-set tooth of the blade to the bed rail was
        14 3/4" (375 mm), make sure the indicator reads 14 3/4" (375 mm) on the scale.
                                                                  Loosen indicator

Frame Setup
       Before performing the following alignment procedures, setup the mill on firm, level
       ground.
Level the frame and adjust the saw head as described in Section 3.1 Sawmill Setup.
   1. Remove the blade and replace the blade wheel belts. New blade wheel belts are required
      to perform the complete alignment procedure.
   2. Blow sawdust off of the blade guide assemblies. Remove sawdust from the blade hous-
      ings.
   4. Adjust the outer blade guide arm in or out until the outer blade guide is approximately 24”
      from the inner blade guide.
5. Install a new blade and apply the appropriate tension (See Section 3.3).
6. Close the blade housing covers and make sure all persons are clear of the saw head.
8. Engage the blade, rotating the blade until the blade positions itself on the wheels.
       The blade wheels should be adjusted so they are level in the vertical and horizontal
       planes. If the blade wheels are tilted up or down, the blade will want to travel in the tilted
       direction. If the blade wheels are tilted horizontally, the blade will not track properly on the
       wheels.
   1. Use the blade guide alignment tool to check the vertical alignment of each blade wheel.
      Attach the tool to the blade near the inner blade guide mount. Be sure the tool does not
      rest on a tooth or burr, and is lying flat against the bottom of the blade.

   2. Move the saw carriage so the front end of the tool is positioned over the first bed rail.
      Measure from the bottom of the tool to the top surface of the bed rail.
   3. Move the saw carriage so the rear of the tool is positioned over the bed rail. Again, mea-
      sure from the bottom of the tool to the bed rail.
   4. If the two measurements differ by more than 1/16" (1.5 mm), adjust the vertical tilt of the
      drive-side blade wheel.
        To tilt the wheel , loosen the bottom adjustment screw one quarter turn. Loosen the jam
        nut on the top adjustment screw and tighten the screw. Tighten the top and bottom jam
        nuts.

   5. Recheck the vertical tilt of the drive-side blade wheel with the blade guide alignment tool.
      Readjust the blade wheel as necessary until the front and rear of the tool are the same
      distance from the bed rail (within 1/16" [1.5 mm]).
6. Remove the tool from the blade and reattach it near the outer blade guide assembly.
   7. Measure from the tool to the bed rail at both ends of the tool. If the measurements at the
      front and rear ends of the tool differ by more than 1/16" (1.5 mm), adjust the vertical tilt of
      the idle-side blade wheel.
       To tilt the wheel down, loosen the top adjustment screw one quarter turn. Loosen the jam
       nut on the bottom adjustment screw and tighten the screw. Tighten the top and bottom
       jam nuts.

   8. Recheck the vertical tilt of the idle-side blade wheel with the blade guide alignment tool.
      Readjust the blade wheel as necessary until the front and rear of the tool are the same
      distance from the bed rail (within 1/16" [1.5 mm]).
        See Figure 7-14. The horizontal tilt of the blade wheel should be adjusted so that the gul-
        let of an 1-1/4" blade is 1/8" (3 mm) out from the front edge of the wheel (±1/32 [0.75
        mm]).

FIG. 7-16
       Each Wood-Mizer sawmill has two blade guide assemblies that help the blade maintain a
       straight cut. The two blade guide assemblies are positioned on the saw head to guide the
       blade on each side of the material being cut.
       One blade guide assembly is mounted in a stationary position on the drive side of the saw
       head. This assembly is referred to as the "inner" blade guide assembly.
       The other blade guide assembly is mounted on the idle side of the saw head. It is referred
       to as the "outer" assembly and is adjustable for various widths of materials to be pro-
       cessed.
   1. Install the outer blade guide assembly (with waterlube tube) to the mounting block on the
      blade guide arm. Position the assembly so the roller flange is 1/8" (3.0 mm) from the
      blade.
   2. Install the inner blade guide assembly to the mounting block on the saw head. Position
      the assembly so the roller flange is 1/16" (1.5 mm) from the blade.
       Tighten the two previously-loosened tilt adjustment screws to secure the blade guide
       assembly. Loosen the top vertical adjustment jam nut and tighten the bottom vertical
       adjustment jam nut to adjust the blade guide roller up so it does not touch the blade.

        The blade guide arm moves the outer blade guide in and out. If the arm becomes loose,
        the blade guide will not deflect the blade properly, causing inaccurate cuts. A loose blade
        guide arm can also cause blade vibration.
1. Adjust the blade guide arm in to 1/2" (15 mm) from fully closed.
        See Figure 7-18. Use the inside top and bottom screws to adjust the arm up until the
        slide pad touches the saw head brace tube. Tighten the jam nuts.

2. Adjust the blade guide arm in all the way toward the other blade guide.
   3. Use the outside top and bottom screws to adjust the arm up until the slide pad touches
      the saw head brace tube. Tighten the jam nuts.
FIG. 7-19
   4. Measure the distance between the blade guide arm and back edge of the blade. Adjust
      the appropriate side screws on the blade guide arm housing so the arm is measures the
      same distance from the blade at both ends of the arm.
   5. To move the blade guide end of the arm toward the front of the sawmill, loosen jam nuts
      on the front inside screw and the rear outside screw. Turn the screws counterclockwise
      one full turn and tighten the jam nuts. Loosen the jam nuts on the front outside screw and
      the rear inside screw. Turn the screws clockwise until they touch the arm, back off 1/4”
      turn, and tighten the jam nuts.
   6. To move the blade guide end of the arm toward the rear of the sawmill, loosen jam nuts
      on the front outside screw and the rear inside screw. Turn the screws counterclockwise
      one full turn and tighten the jam nuts. Loosen the jam nuts on the front inside screw and
      the rear outside screw. Turn the screws clockwise until they touch the arm, back off 1/4”
      turn, and tighten the jam nuts.
Perform the following steps to achieve proper blade deflection with the blade guides.
   1. Raise the saw head until the blade is 15" (375 mm) above a bed rail. Measure the actual
      distance with a tape from the top of the rail to the bottom of the blade.
   2. Make sure the two vertical adjustment set screws are threaded into the blade guide shaft
      until they touch each other.
        Loosen the bottom jam nut and tighten the top jam nut until the blade guide deflects the
        blade down until the bottom of the blade measures 14 3/4" (370 mm) from the bed rail.

                      NOTE: Be sure that the blade guide deflector rod clears the
                      blade on both guide assemblies. The rod on the outer guide
                      assembly should be checked with the arm all the way in
                      and all the way out.
       The blade guides should be adjusted properly in the vertical plane. If the blade guides are
       tilted vertically, the blade will try to travel in the tilted direction.
       A Blade Guide Alignment Tool (BGAT) is provided to help you measure the vertical tilt of
       the blade.
1. Open the adjustable blade guide arm 1/2" (15 mm) from full open.
   2. Clamp the alignment tool on the blade. Position the tool close to the outer blade guide
      roller. Be sure the tool does not rest on a tooth or burr, and is lying flat on the blade.

   3. Move the carriage so that the front end of the tool is positioned above the bed rail. Mea-
      sure the distance from the bed rail to the bottom edge of the tool.
   4. Move the carriage so that the back end of the tool is positioned above the bed rail. Mea-
      sure the distance from the bed rail to the bottom edge of the tool.
   5. If the measurement from the tool to the bed rail is not equal within 1/32" (.75 mm), adjust
      the vertical tilt of the outer blade guide roller.
6. Loosen one set screw at the side of the blade guide assembly.
                                                                                                        FIG. 7-22
   7. Move the blade guide alignment tool close to the inner blade guide roller assembly and
      repeat the above steps. Adjust the vertical tilt of the inner blade guide if necessary.
   8. After adjusting the vertical tilt of the blade guides, recheck the blade deflection and adjust
      if necessary.
       If the blade guides are tilted in the wrong direction horizontally, the back of the blade may
       contact the flange as the roller is spinning down, causing it to push the blade away from
       the guide roller.
   1. Remove the blade guide alignment tool from the blade and adjust the blade guide arm
      halfway in.
   2. Remove the clip from the blade guide alignment tool. Place the tool against the face of
      the outer blade guide roller.

4. Measure between the back edge of the blade and the other end of the tool ("A").
The roller should be tilted slightly to the left (’A’ 1/8" [3 mm] less than ’B’ ±1/8" [3 mm]).

   5. Repeat the above steps for the inner blade guide roller assembly.
       Each blade guide must be adjusted so the roller flange is the correct distance from the
       back edge of the blade. If the flange is too close to or too far from the blade, the sawmill
       will not cut accurately.
   1. Measure the distance between the flange on the inner blade guide roller to the back edge
      of the blade. This distance should measure 1/16" (1.5 mm). Adjust the roller back or for-
      ward if necessary.
       See Figure 7-25. Loosen the top and one side screw shown. Tap the blade guide forward
       or backward until properly positioned. Retighten the screws and jam nuts.
                                                                                          FIG. 7-25
   2. Measure the distance between the flange on the outer blade guide roller to the back edge
      of the blade. This distance should measure 1/8" (3.0 mm). Adjust the roller back or for-
      ward if necessary.
        Logs and boards are clamped against the side supports when sawing. The sides supports
        must be square to the bed to ensure square lumber.
1. Place a flat board across the bed rails. Swing a side support up so that it is vertical.
   2. Pull back at the top of the support to eliminate slack as if a log were being clamped
      against it.
   3. Place a square against the face of the side support. The side support should be square or
      slightly tilted forward 1/32" (0.8 mm). Adjust the vertical tilt of the side support if neces-
      sary.
        See Figure 7-26. Loosen the top adjustment bolt, adjust the side support, and retighten
        the bolt.Turn the adjustment bolt counterclockwise to tilt the top of the side support for-
        ward.
                                                                                   Side Support

4. Repeat the vertical check for the remaining side supports and adjust as necessary.
       After the entire sawmill has been aligned and all adjustments made, check that the blade
       height scale indicates the true distance from the blade to the bed rails.
   1. Move the saw carriage so the blade is positioned directly above one of the bed rails. Mea-
      sure from the bottom edge on a down-set tooth of the blade to the top of the bed rail, near
      the inner blade guide assembly.
   2. View the blade height scale with eyes level with the indicator. The scale should indicate
      the actual distance from the blade to the bed rail. Adjust the indicator if necessary.
       See Figure 7-27. Loosen the indicator bracket mounting nut. Adjust the bracket up or
       down until the indicator is aligned with the correct mark on the scale (+0 -1/32 [0.8 mm]).
       Retigten the indicator mounting nut.
       For example, if the measurement from the down-set tooth of the blade to the bed rail was
       14 3/4" (375 mm), make sure the indicator reads 14 3/4" (375 mm) on the scale.
                                                                  Loosen indicator
                                                                  bracket mounting
                                                                  nut

       The standard LT15 is supplied with two bed sections, one head assembly, and an auxil-
       iary bed rail.
       See Figure 8-1. The figure below shows the recommend bed setup for a standard LT15
       (revision D4.00 and later). The auxiliary bed rail is installed to pre-existing holes between
       the two main bed rails of the second bed section to support shorter logs as shown below.
       Also shown is the recommended bed setup of an LT15 when using the SLR Shingle/Lap
       Siding Option. A third bed section and relocation of the auxiliary bed rail are required to
       use the SLR option on the LT15. Holes need to be drilled in the bed frame to mount the
       auxiliary bed rail in this position.

       TIP: The threaded holes at the end of the splice are provided to help remove the splice if
       you wish to disassemble the sawmill. Remove the two splice bolts from the middle holes
       and thread into the end holes. Evenly turn the bolts clockwise to push the splice pins out
       of the track rail holes.
       See Figure 8-7. To connect a bed with old-style track rails (without pin holes) to a bed
       with new-style track rails (with pin holes), use the adaptor splice (Part No. 016173). Insert
       the splice pins into the holes in the new track rail. Secure with two 3/8-16 x 1” hex head

        The saw carriage is equipped with two lock pins at the bottom of the mast near the track
        rollers. These pins can be adjusted to three different positions:
   1. Assembly/Disassembly position (prior to Rev. E1.00 only). To move the pins so they
      do not interfere with installing the carriage to the bed frame, rotate both pins so they rest
      in the upper notch on the pin bracket.
   2. Operation position. This position allows the pins to catch the bottom of the track rail,
      preventing the saw head from tilting and disengaging the bed frame. NOTE (Rev. D6.00+
      Only): The pins are designed so if they are inadvertently left in the assembly position,
      they will move to the operation position when the carriage is moved.
   3. Travel position. To secure the saw head to the bed frame during travel, rotate the pin at
      the end of the sawmill so it is clear of the pin bracket. Be sure the pin engages the hole in
      the bed frame tube. The other pin should remain in the operation position to prevent the
      saw head from tilting.

   1. Before beginning saw carriage assembly, make sure both lock pins are in the assem-
      bly/disassembly position (lock pins seated in upper notches of pin rest brackets). To repo-
      sition pin, pull pin outward, rotate as desired, and release into proper position.
   2. Position the saw head carriage at the end of the bed frame assembly. Carefully slide the
      saw head carriage rollers onto the bed frame track. Keep the carriage square to the bed
      to avoid putting the track rollers in a bind.
    3. Place both carriage lock pins in the operation position to secure carriage onto bed frame
       assembly.
    4. Locate the middle track cover and soak the felt wiper with Dexron III transmission fluid,
       10W30 motor oil or 3-in-1 turbine oil. Remove the existing hex bolts and flat washers
       located on the inside of each track roller housing cover. Position the middle track cover
       between the two track roller housings so the opening in the cover is positioned over the
       feed rope pulleys. Replace the two hex head bolts and flat washers.
    5. Install a slotted track scraper to each track roller housing with a 3/8” flat washer and
       3/8-16 x 3/4” hex head bolt.
