SECTION 2 SAFETY
2.1 Safety Symbols

The following symbols and signal words call your attention to instructions concerning your
personal safety. Be sure to observe and follow these instructions.

DANGER! indicates an imminently hazardous situation

which, if not avoided, will result in death or serious injury.

WARNING! suggests a potentially hazardous situation

which, if not avoided, could result in death or serious injury.

CAUTION! refers to potentially hazardous situations which,

if not avoided, may result in minor or moderate injury or
damage to equipment.

IMPORTANT! indicates vital information.

 Safety
Safety Instructions 2
2.2 Safety 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.

OBSERVE SAFETY INSTRUCTIONS

IMPORTANT! Read the entire Operator's Manual before operating

the sawmill. Take notice of all safety warnings throughout this man-
ual and those posted on the machine. Keep this manual with this
machine at all times, regardless of ownership.

Also read any additional manufacturer’s manuals and observe any

applicable safety instructions including dangers, warnings, and
cautions.

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.

IMPORTANT! It is always the owner's responsibility to comply with

all applicable federal, state and local laws, rules and regulations
regarding the ownership, operation and towing of your Wood-Mizer
sawmill. All Wood-Mizer mill owners are encouraged to become
thoroughly familiar with these applicable laws and comply with
them fully while using the mill.

 Safety
2 Safety Instructions
WEAR SAFETY CLOTHING

WARNING! Secure all loose clothing and jewelry before operating

the sawmill. Failure to do so may result in serious injury or death.

WARNING! Always wear gloves and eye protection when handling

bandsaw blades. Changing blades is safest when done by one per-
son! Keep all other persons away from area when coiling, carrying
or changing a blade. Failure to do so may result in serious injury.

WARNING! Always wear eye, ear, respiration, and foot protection

when operating or servicing the sawmill.

KEEP SAWMILL AND AREA AROUND SAWMILL CLEAN

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.

2-3 1597doc111810 Safety

 Safety
Safety Instructions 2
HANDLE FUEL/LUBRICANTS SAFELY

DANGER! Due to the flammable nature of fuel and oil, never

smoke, weld, grind or allow sparks near your engine or storage
tanks, especially during times of fueling.

DANGER! Never allow fuel to spill on a hot engine during fueling

operations or otherwise. The hot temperature of your engine could
induce a fire or explosion.

WARNING! Store gasoline away from sawdust and other flamma-

ble materials. Failure to do so may 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.

DISPOSE OF SAWING BY-PRODUCTS PROPERLY

IMPORTANT! Always properly dispose of all sawing by-products,

including sawdust and other debris, coolant, oil, fuel, oil filters and
fuel filters.

Safety 1597doc111810 2-4

 Safety
2 Safety Instructions
USE CAUTION WHEN WORKING WITH BATTERIES

DANGER! Batteries expel explosive gases. Keep sparks, flames,

burning cigarettes, or other ignition sources away at all times.
Always wear safety goggles and a face shield when working near
batteries. Failure to do so will cause serious injury. 1

WARNING! Battery posts, terminals and related accessories con-

tain lead and lead compounds, chemicals known to the State of
California to cause cancer and reproductive harm. Wash hands
after handling.

WARNING! Charge the battery in a well ventilated area. Do not

attempt to charge a frozen battery.

Use extreme care to avoid spilling or splashing electrolyte (which is

dilute sulfuric acid) as it can destroy clothing and burn the skin. If
electrolyte is spilled or splashed on clothing or the body, it should
be neutralized immediately and then rinsed with clean water. A
solution of baking soda, or household ammonia, and water may be
used as a neutralizer.

Electrolyte splashed into the eyes is extremely dangerous. If this

should happen, force the eye open and flood it with cool, clean
water for approximately fifteen minutes. A doctor should be called
immediately when the accident occurs and “on-the-spot” medical
attention given if possible. If a doctor cannot come to the scene of
the accident immediately, follow his instructions concerning actions
to take. Do not add eye drops or other medication unless advised
to do so by the doctor. Do not place a battery or acid within the
reach of children. If acid (electrolyte) is taken internally drink large
quantities of water or milk. Follow with milk of magnesia, beaten
egg or vegetable oil. Call a physician immediately.

If electrolyte is spilled or splashed on any surface of the machine, it

should be neutralized and rinsed with clean water.

CAUTION! Do not overcharge the battery. Overcharging may

reduce the overall service life of the battery.

CAUTION! Be sure the battery is fully charged before transporting

the sawmill. If the battery is not fully charged, excessive vibration
could reduce the overall service life of the battery.

Safety Instructions 2
CAUTIONS FOR SAWMILL SETUP

WARNING! Do not set up the mill on ground with more than a 10

degree incline. If setup on an incline is necessary, put blocks under
one side of the mill or dig out areas for the legs to keep mill level.
Setting up the mill on an incline could cause it to tip over, resulting
in serious personal injury.

WARNING! The sawmill weighs 1100 lbs. The center of gravity of

the carriage is off-center toward the operator side. The higher the
saw head from the bed frame, the more easily the mill can be
tipped toward the operator side. A minimum of three people (four
recommended) is required to safely load or unload the sawmill
from a pickup truck.

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,

3.1 Sawmill Setup

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.

Replacing The Blade 3
3.2 Replacing The Blade

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! Always wear gloves and eye protection when

handling bandsaw blades. Changing blades is safest when
done by one person! Keep all other persons away from
area when coiling, carrying or changing a blade. Failure to
do so may result in serious injury.

Adjust the blade guide arm all the way open.

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.

To Load Logs

1. Move the saw carriage to the front end of the frame.

CAUTION! Before loading a log, be sure the cutting head is

moved far enough forward so the log does not hit it. Failure
to do so may result in machine damage.

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.

CAUTION! Be sure the log clamps are adjusted out of the

path of the log before loading a log onto the bed. Failure to
do so may result in machine damage.

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.

5. Position the log at the foot of the ramps.

6. Use a cant hook to roll the log up the ramps and onto the sawmill bed. Position the log
against the side supports.

NOTE: Position the log on the bed sections to maximize

support of the log by the bed. If the log overhangs the bed,
(particularly if the optional bed extension is installed) it may
tend to sag, resulting in inaccurately sawn lumber.

7. Remove the log ramps and set aside.

CAUTION! The saw head will hit the spring-loaded ramp

stops when adjusted for low cuts. Remove the loading
ramps before sawing to prevent damage to the saw head
and/or blade guide arm.

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.

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.

Cutting The Log 4
4.6 Cutting The Log

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.

4 Cutting The Log
9. Remove the wedge if it was used. Remove the clamps and turn the log 90 or 180
degrees. Make sure the flat on the log is placed flat against side supports if turned 90
degrees. Make sure it is placed on bed rails if turned 180 degrees. If the log was turned
90 degrees and you are using the wedge to compensate for taper in the log, use the
wedge again on the second side of the log until the heart is parallel with the bed.

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.

Edging 4
4.7 Edging

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.

2. Stack the flitches on edge against the side supports.

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).

4. Adjust the blade height to edge a few of the widest boards.

5. Loosen the clamps and turn the edged boards over to edge the other side.

6. Repeat steps 2-4.

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.

4 Blade Height Scale
4.8 Blade Height Scale

See Figure 4-9. The blade height scale is attached to the carriage head frame. It
includes:

„ a blade height indicator

„ an inch scale

„ a magnetic quarter scale (after 3/99)

Inch Scale
Blade
Height
Indicator

150028

FIG. 4-9

The Inch Scale

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.

4-17 1597doc111810 Sawmill Operation

 Sawmill Operation
Blade Height Scale 4
The Quarter Scale

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.

Standard Quarter Scale

Scale Actual Board Thickness
4/4 1" (25 mm)
5/4 1 1/4" (32 mm)
6/4 1 1/2" (38 mm)
8/4 2" (51 mm)
TABLE 4-1
To use the quarter scale, look at the blade height indicator.

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.

4 Water Lube Operation
4.9 Water Lube Operation

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.

3H0129

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.

WARNING! Use ONLY water and Wood-Mizer Lube Addi-

tive with the water lube accessory. Never use flammable
fuels or liquids such as diesel fuel. If these types of liquids
are necessary to clean the blade, remove it and clean with
a rag. Failure to do so can damage the equipment and may
result in serious injury or death.

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.

Loading & Transporting the Sawmill 4
4.10 Loading & Transporting the Sawmill

The assembled sawmill can be manually loaded into and transported in an appropriately
equipped pickup truck:

WARNING! The sawmill weighs 1100 lbs. The center of

gravity of the carriage is off-center toward the operator side.
The higher the saw head from the bed frame, the more eas-
ily the mill can be tipped toward the operator side. A mini-
mum of three people (four recommended) is required to
safely load or unload the sawmill from a pickup truck.

1. Remove the leg assemblies or adjust them above the bottom of the bed frame.

Before lifting, moving or transporting the sawmill, be sure

the carriage lock pins are properly engaged. To prevent the
carriage from unexpectedly sliding on the rails, the pin at
the end of the sawmill must engage the hole in the bed
frame. The other pin must be left in the operation position.
Failure to do so may result in serious injury and/or machine
damage.

See Figure 4-12. See Section 8.7 for a detailed description of carriage lock pin opera-
tion.

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.

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 dam-
age, serious injury or death.

 Sawmill Operation
Loading & Transporting the Sawmill 4
6. Position two people at the sides of the frame, about two feed from the end. As they lift the
frame, the third person should back the truck slowly under the sawmill until the end of the
frame is resting firmly on the bed of the truck. Remember that the operator side is heavier
than the opposite side.

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.

If the key is turned on and moving parts activated, serious
injury may result.

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.

See Figure 5-2.

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.

CAUTION! Keep track rails free of rust. Formation of rust

on the track rail in the areas where the cam bearings roll
can cause rapid deterioration of the track rail's surface.

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.

5 Charging The Battery (D10/G15 Only)
5.12 Charging The Battery (D10/G15 Only)

DANGER! Batteries expel explosive gases. Keep sparks,

flames, burning cigarettes, or other ignition sources away at
all times. Always wear safety goggles and a face shield
when working near batteries. Failure to do so will cause
serious injury. 1

WARNING! Battery posts, terminals and related accesso-

ries contain lead and lead compounds, chemicals known to
the State of California to cause cancer and reproductive
harm. Wash hands after handling.

WARNING! Charge the battery in a well ventilated area. Do

not attempt to charge a frozen battery.

Use extreme care to avoid spilling or splashing electrolyte

(which is dilute sulfuric acid) as it can destroy clothing and
burn the skin. If electrolyte is spilled or splashed on clothing
or the body, it should be neutralized immediately and then
rinsed with clean water. A solution of baking soda, or
household ammonia, and water may be used as a neutral-
izer.

Electrolyte splashed into the eyes is extremely dangerous.

If this should happen, force the eye open and flood it with
cool, clean water for approximately fifteen minutes. A doc-
tor should be called immediately when the accident occurs
and “on-the-spot” medical attention given if possible. If a
doctor cannot come to the scene of the accident immedi-
ately, follow his instructions concerning actions to take. Do
not add eye drops or other medication unless advised to do
so by the doctor. Do not place a battery or acid within the
reach of children. If acid (electrolyte) is taken internally
drink large quantities of water or milk. Follow with milk of
magnesia, beaten egg or vegetable oil. Call a physician

7 Routine Alignment Procedure
SECTION 7 SAWMILL ALIGNMENT
Two alignment procedures are available to realign the sawmill if necessary. The Routine
Alignment instructions should be performed as necessary to solve sawing problems not
related to blade performance. The Complete Alignment procedure should be performed
approximately every 1500 hours of operation (sooner if you regularly transport the saw-
mill over rough terrain).

7.1 Routine Alignment Procedure

Level the frame and adjust the saw head as described in Section 3.1 Sawmill Setup.

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.

5. Start the engine.

6. Engage the blade, rotating the blade until the blade positions itself on the wheels.

WARNING! Do not spin the blade wheels by hand.

Spinning the blade wheels by hand may result in serious
injury.

7. Disengage the blade. Turn the engine off.

 Sawmill Alignment
Routine Alignment Procedure 7
Blade Guide Arm Alignment

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.

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.

NOTE: When adjusting the blade guide arm screws, be

careful not to tighten the screws too much or put the arm in
a bind. Operate the blade guide arm knob to ensure the
arm moves easily in and out when the knob is turned.

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.

Routine Alignment Procedure 7
Blade Guide Vertical Tilt Alignment

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.

See Figure 7-3.

Routine Alignment Procedure 7
Blade Guide Flange Spacing

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.

HINT: When adjusting blade guide spacing, loosen the top

set screw and one side set screw only. This will ensure hor-
izontal and vertical tilt adjustments are maintained when the
adjustment screws are retightened.

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.

Side Support Alignment

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.

7 Routine Alignment Procedure
Blade Height Scale Adjustment

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.

Blade Wheel Alignment

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.

Blade Guide Installation

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.

NOTE: Before installing the blade guide assemblies,

remove the blade guide adjusting screws and apply a lubri-
cating oil such as 10W30 or Dexron III to each screw. This
will prevent the screws and threaded holes from corroding
and make screw adjustments easier.

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 Guide Arm Alignment

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.

NOTE: When adjusting the blade guide arm screws, be

careful not to tighten the screws too much or put the arm in
a bind. Operate the blade guide arm knob to ensure the
arm moves easily in and out when the knob is turned.

Blade Guide Vertical Tilt Alignment

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.

Blade Guide Flange Spacing

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.

HINT: When adjusting blade guide spacing, loosen the top

set screw and one side set screw only. This will ensure hor-
izontal and vertical tilt adjustments are maintained when the
adjustment screws are retightened.

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.

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-

Blade Height Scale Adjustment

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.

8.1 Overview

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.

8 Saw Carriage Assembly

8.7 Saw Carriage Assembly

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.
