DECALS
Decals located on your Bandit equipment contain useful information to assist you in operating your equipment
safely. Some of the decals on your machine and their location are shown in this section.
It is very important that all decals remain in place and in good condition on your machine. Please follow
the care and instructions given below.

1. You should use soap and water to keep your decals clean. Never use mineral spirits or any other
abrasive cleaners.
2. Immediately replace any missing or damaged decals. The location the decal is going to be applied
to must be clean and dry, and at least 40°F (5°C) before applying decal.
3. When the need arises to replace a machine component with a decal attached, be sure and replace
the decal.
4. Replacement decals are available, and can be purchased from the manufacturer or your Bandit Dealer.
5. Peel back about half of the backer paper on the decal. Position it on the flat, dry, clean surface so it
is smooth and secure. Peel off the remainder of the backer paper as you continue to stick the decal
on the surface.
6. Rub decal from the center outward to remove air bubbles and to secure contact.

! WARNING

Make sure you are in manual mode before running any hydraulic function for maintenance. See
previous page for a reference of the manual valve controls.

1. Yoke Lock In / Out:

The yoke lock pins are located on top of the cutterhead chamber. Some maintenance requires you to
work under the feedwheel while in the raised position. The yoke assembly requires two safety devices to be
in place before maintenance can begin.
A. Disengage clutch and wait for the cutterhead to come to a complete stop. Leave the engine on.
B. Raise the yoke to its maximum height using the yoke manual control valve.
C. Pull the control handle towards you to extend the yoke lock pins.
D. Use the safety chain attached to the headache rack and secure it to the lugs located on both sides
of the feedwheel yoke.
E. With the safety devices in place lower the yoke until it contacts the yoke lock pins and the safety
chains are in place.
F. Turn off the engine, remove the ignition key, make sure the ignition key is in your possession, wait 2
minutes and then disconnect the battery. You are now ready to work under the yoke.
2. Stabilizer Up / Down (Trailerized Only):
To lower the stabilizer, and stabilize the machine, pull the control handle towards you. To raise the stabilizer
to transport the machine, push the control handle away from you.
3. Gate Open / Close:
To open the gate pull the control handle towards you. To close the gate, push the control handle away
from you. 
4. Yoke Up / Down:
To lift the yoke assembly pull the control handle towards you. When the machine is in the Manual
Mode, the yoke is hydraulically locked in the neutral ­position. The yoke assembly will float on the incoming
­­material when the control panel is in the Radio Mode. The yoke does not use hydraulic pressure to go down.
! WARNING
NEVER use the tether or radio remote button to hold the yoke in the raised position if work is to be done
under or around the feedwheel. Use the yoke lock pins and safety chains as explained above.
! WARNING
NEVER use the off position of the yoke control valve to lock the yoke up if work is to be done
under or around the feedwheel. Use the hydraulic yoke lock pins and safety chains p ­ rovided by the
­manufacturer. When all safety devices are in place, you may start performing maintenance to the machine.
! DANGER
The yoke can be lowered with the control valve, even if the engine is off. Always use the lock pins
and safety chains when working under the yoke.
5. Feedwheel Forward / Off / Reverse:
To have material be fed into the machine push the control handle away from you. To reverse material out
of the machine pull the control handle towards you. To stop the feedwheel; place the control handle in the
neutral position.
6. Infeed Conveyor Forward / Off / Reverse:
To have material be fed into the machine push the control handle away from you. To reverse material
out of the machine pull the control handle towards you. To stop the conveyor; place the control handle in the
neutral position.

MODEL 3680 CONTROLS

CONTROLS
7. Discharge Conveyor Fold Up / Down:
The discharge conveyor must be stowed in the folded position when moving the machine. Before folding
or unfolding the discharge conveyor, make sure the engine is at idle and everyone is clear from the work
area around the machine.
Before folding or unfolding, operate the valve to position the discharge further in the current position. Hold
the valve position for 4-5 seconds until the pressure gauge reaches system pressure. Repeat this procedure
for both conveyor fold valves. This will purge the hydraulic system of any air.
To unfold the discharge conveyor in the operating position: first pull the 2nd discharge conveyor fold control
handle until the mid section is fully extended. Then unfold the upper section by pulling the 1st discharge fold
control handle until the upper section is fully extended.
To fold the discharge conveyor in the transport position: first push the 1st discharge fold control handle
away from you until the upper section is fully folded. Then push the 2nd discharge fold control handle away
from you until the discharge conveyor comes to rest on the discharge conveyor support.
! DANGER

Do not slam the discharge conveyor to a stop. Always feather the controls to allow a smooth stop. Slamming
the discharge conveyor could cause ­extensive damage to the machine or cause serious injury or death.
! DANGER 
Avoid power lines. Electrocution is possible if the recycler touches a power line. Take the following ­precautions.
Position the recycler and any loading equipment at least 10 feet (3 meters) away from all power lines. If the
machine contacts a power line, stay away from the machine. Failure to do this could result in serious injury or death.
NOTICE
If the machine is equipped with a height adjustable discharge, make sure it is in the correct position before
folding the discharge.
8. Conveyor Up / Down (If Equipped):
To adjust the height of the discharge conveyor push or pull the control handle until the desired height is
reached.
If the machine is equipped with the optional height adjustable discharge, the discharge must be placed in
a certain position before folding. Trailerized machines or track machines equipped with a CAT C-27 engine
must have the height adjustable discharge placed in the upper most position before folding the discharge.
Track machines (unless equipped with a CAT C-27 engine) must have the height adjustable discharge placed
in lower most position (resting on the stops) before folding the discharge.
9. Auger Forward / Off / Reverse:
To operate the augers in the normal forward condition push the control handle away from you. To stop
the augers; place the control handle in the neutral position.
! WARNING
NEVER operate the augers in reverse for more than one second at a time. Leaving the augers
in reverse will cause material to build up against the rear auger pan, damaging the auger drive.
NOTICE
Augers and discharge have to be engaged before feed system will go forward
when in remote mode.
10. Discharge Conveyor Forward / Off / Reverse:
To operate the discharge in the forward direction push the control handle away
from you. To stop the discharge; place the control handle in the neutral position.
11. Test Port:
To check hydraulic pressures, place the pressure gauge in the test port.
12. Emergency Shut Down Switches:
There are four emergency shut down switches located at each corner of the
machine. When any one of these are pushed in, the machine will stop. All switches
must be twisted clockwise and pulled out for the machine to work again.

MODEL 3680 TRANSPORTATION PROCEDURES

LOADING & UNLOADING SELF-PROPELLED MACHINES

! WARNING
BEFORE ATTEMPTING TO USE A TRAILER FOR TRANSPORT, MAKE SURE THE TRAILER TOWING
VEHICLE IS APPROPRIATE FOR THE TASK.
1. The trailer has a cargo weight rating capacity for the weight of the machine. The combined weight of the
trailer and the machine can not exceed the load capacity of the tires, axles, hitch coupler system or the
GVWR (Gross Vehicle Weight Rating) of the trailer.
2. The trailer must have a lighting system and a braking system to match and perform correctly off the
towing vehicle’s system. You must meet the Federal and your States’ Department of Transportation
Code of Regulations concerning lights, brakes, and highway transit.
3. Make sure the towing vehicle has the hauling and hitch capacity ratings for the trailer and machine
combination. The towing vehicle must be mechanically sound and capable of handling the towing job.
4. The trailer should be constructed with appropriate chain down positions for the specific sized machine.
You must have binders that will withstand the strain of the machine trying to move while it is being
transported.
5. Follow the trailer manufacturer’s recommendations for the amount of weight on the tongue or hitch
according to the total machine package weight to correctly position the machine on the trailer bed.
6. The trailer and machine height must not exceed legal towing height restrictions.

! WARNING
BEFORE LOADING OR UNLOADING THE TRACK MACHINE, INSPECT AND CONFIRM THE FOLLOWING
STEPS: When loading or unloading the self-propelled machine on the trailer, use care and caution. The
maneuvering of the equipment must be slow, smooth, and intentional, not fast and jerky.

1. Make sure the trailer and towing vehicle are parked on a flat surface. They must be stable on the surface
with the brakes locked and/or the wheels chocked to avoid unwanted movement.
2. Remove and store the chains and binders used for transporting.
3. Confirm that there are not any obstacles on the trailer bed, around the trailer that may cause restricted
movement of the machine or the operator.
4. The only person in the loading area should be the one that is operating the machine controls, and they
should be very experienced with the controls on this machine.
5. If you are on streets, roads or public areas, position the warning cones etc, per your company’s safety policy.
6. Follow all pre-startup instructions for the machine.
7. Go to the “Mode 2” screen on the control panel and select “Creep Track”. This will reduce the maximum
speed of the tracks to the selected percentage and the engine should be at an idle.
8. Align the machine with the trailer bed, and the loading ramps. The only equipment movement should be
slowly, straight on or straight off the trailer.
9. With the engine and the machine at as low a speed as possible, move the machine toward the ramp
system. Make sure the alignment is correct throughout the travel.
10. Properly secure the equipment and the area to avoid any possible accidents or dangers.

MAINTENANCE
The Beast Recycler is a very simple machine to maintain. If you will follow a regular scheduled ­preventative
­maintenance program, you should have years of trouble free operation.

! DANGER
Before attempting any type of maintenance, d ­ isengage clutch, wait for the cutterhead to come to a c­ omplete
stop, turn off engine, remove the ignition key, make sure the ignition key is in your possession, wait 2 minutes
and then disconnect the battery.

! DANGER
Do not let anyone operate or maintain this machine until they have thoroughly read this manual, ­reviewed
the equipment decals, watched the equipment video, and has been properly trained. You can purchase
­additional Smoracy, LLC manuals, decals and videos for a nominal fee.

NOTICE

­ rocedures.
p

NOTICE
Failure to properly break-in your engine may result in poor bearing and piston ring surfaces.

NOTICE
The machine has only been run for a short time to test proper hydraulic pressures, possible leaks, etc.
The fuel tank will be empty. Fuel is provided through a small auxiliary tank for testing. This ­immensely helps
maintain safety in our manufacturing facility and while shipping.

NOTICE
Expensive damage to the machine will occur if proper preparation is not taken before welding on the
­machine. Be sure to disconnect both battery cables, the engine ECM (engine control module), also plugs
in the control cabinet such as clutch module and flex-air (If equipped) and all the plugs on the control box
need to be unplugged before welding. ­Follow the specific Engine MFG. ­instructions for proper welding and

The cutterhead is one of the most important components to keep a preventive maintenance schedule on. The
cutterhead is the heart of your recycler, it does most of the work. The cutterhead MUST be maintained daily.

CUTTERBODY
The cutterbody used in the Beast has a leading edge referred to as the “raker”. The raker is designed to
control the depth of cut that the cutter tooth will take. The more the raker wears, the larger the cut that the
cutter tooth is allowed to take. If using a small hole screen taking large cuts means that the material has to
beat around inside the cutterhead chamber until small enough to exit through the screen. This robs horsepower
that could be used at the cutter tooth. Also, taking bigger cuts puts undue stress on the cutterhead shaft
leading to possible shaft failure. Over bite will cause cutterbodies to stretch and fail prematurely. This stress
will transfer into the cutterbody bolts and cause them to break or bend.
When new, the cutterbody has a hard surface weld applied to the raker area. It is imperative that this area
be maintained. The diagrams below show the height of the raker area when new and the maximum allowable
wear. While in the machine these measurements are taken from the face of the cutterhead drum. When worn,
remove the cutterbody from the cutterhead and build up the raker area with a hard surface weld using the
dimensions below as a guide. You could also lay a worn cutterbody on a new one to see how far to build up
the worn area. If using a wire feed welder, it is suggested to use a Lincoln Lincore 60-G or a Stoody 101HC
wire. If using a stick welder, it is suggested to use a Lincoln Wearshield 60 or the Stoody Stoodite 2134. If
there is excessive wear, it is recommended that the cutterbody be replaced with a new one. Be careful not to
build up the worn area above the height as when it was new because this will affect how the machine feeds.
Never weld on the cutterbodies while in the machine, as there is the potential for fire. It pays to have
several extra cutterbodies as replacements and weld up worn ones at your leisure.

CUTTERBODY BOLTS
The cutterhead of the Beast uses a replaceable cutterbody that is designed to fail should something foreign
get into the machine. They take an enormous amount of abuse with the bolts that hold the cutterbody in
place being one of the critical components. During the initial design and testing of this machine a bolt was
developed that is made special for Smoracy, LLC just for this application. The tolerances and the length of
the shank make it unique to any other bolt on the market. Maintaining the proper torque on this bolt is also
extremely critical - 700 ft.-lbs. (949 Nm) for 1” bolts or 1000 ft.-lbs. (1356 Nm) for 1-1/4” bolts. Using the wrong
bolts or not keeping them tight allows for movement between the cutterbody and the support arms which in
turn leads to fatigue and failure. Once the cutterbody is allowed to run loose the integrity of the hole in the
support arm is lost and must be replaced. Otherwise the bolt will never be able to stay tight again. Torque
every bolt with a torque wrench, do not rely on the air impact wrench to torque the bolts. If you over torque
these bolts, it can cause premature failure. Also the bolts alone are not strong enough to hold the cutterbody
in place. Clamping of the two (2) support arms helps the bolts hold the cutterbody in place and that is why it
is important that the bolts get torqued with a torque wrench and stay tight.
A few customers have had cutterbodies break loose from the cutterhead. In every case, it was because
they were not using the proper bolt. A lot of lost time and money will occur if there is a failure due to using
inferior parts or not torquing the bolts down to proper torque specifications with a torque wrench. Any warranty
claims will be denied if the cutterhead was run with anything other than parts supplied by Smoracy, LLC.
When ordering new cutterbodies, new bolts must be ordered as well. It is recommended to order extra to
have on hand for future use.

! WARNING
It is very important after you have operated a new machine for approximately an hour to shut down the
machine and recheck all nuts and bolts. It is normal for nuts and bolts to loosen once on a new piece of
machinery. If you tighten them now, there is a good possibility they won’t loosen again. Certain nuts and bolts
must be checked periodically such as cutterbody and cutter teeth nuts and bolts, etc. for torque and fit.
Most of the nuts used on the Smoracy Recycler are self locking. After a nut or bolt has been removed five
times, it should be replaced to ensure proper tightness. The cutterbody and cutter tooth nuts and bolts must
be replaced every time.
Before the engine is started, rotate the cutterhead backwards a full revolution with a pry bar or a wood bar
to make sure the cutterhead has proper clearance. After the engine is started, let the cutterhead turn at the
lowest RPM’s possible. Listen for any type of noise that is foreign. Any steel on steel noise is foreign. If you
hear a noise, stop the engine, find the problem and fix it.

TOOTH LIFE
Tooth life depends on the amount of abrasive materials and contaminates in the raw material, the amount of
production being processed, and how fine the end product is. As a general rule we suggest that you change
your worst 6 teeth daily if they need it or not. You can use these teeth for future running if some may break
or go bad. Changing the six worst teeth will keep your cutterhead operating well. Never stack logs or railroad
ties. Allow this type of material to go through in a single layer. Contact your local dealer or Bandit Industries

stop, turn off engine, remove the ignition key, make sure the ignition key is in your possession, wait 2 minutes
and then disconnect the battery.

1. Disengage clutch and wait for the cutterhead to come to a complete stop. Leave the engine on.
2. Raise the yoke to its maximum height using the yoke manual control valve.
3. With the manual control valve, extend the yoke lock pins.
4. Use the safety chain attached to the headache rack and secure it to the lugs located on the feedwheel yoke.
5. With the safety devices in place lower the yoke until it contacts the yoke lock pins.
6. Turn off engine, remove ignition key, make sure ignition key is in your possession, wait 2 minutes and
then disconnect the battery.
7. Unplug the mill door engine disable plug.
8. Check the chipper drum anvil for knife clearance. The knife anvil clearance should be 0.18” to 0.25” (4.7
to 6.4 mm); adjust as necessary. Check the anvil for wear and replace the anvil as needed.
9. Make sure the chipper drum anvil bolts are tightened, if they are loose add red Loctite (263) tighten and
retorque to the specified torque.
10. Very carefully, manually with a pry bar or wood bar, turn the chipper drum a full revolution. This is to ensure
the chipper knives have proper clearance. If the chipper drum is jammed with debris or frozen in place,
DO NOT attempt to start the engine and engage clutch until the chipper drum rotates freely.
11. Do Not feed this machine with the top feedwheel pinned, blocked or secured in the open position. Remove
any blocks under feedwheel, unchain the feedwheel, and retract the yoke lock cylinder pins to lower the

8 KNIFE POCKET COVER PROCEDURE

If the end product chip size needs to be bigger, pocket fillers can be added to four of the knife pockets.
The chipper drum is considered to be a 2 knife chipper drum because it takes 2 full cuts across the width of
the chipper drum per revolution. If the pocket fillers are added to four of the knife pockets, the chipper drum
will become a 1 knife chipper drum and produce larger chips.

To install the pocket fillers:

1. The knives and holders need to be removed from pockets #1,3,6 and 8.
2. Remove any old Loctite and residue out of the threaded holes in the pocket sub holder and all mounting
surfaces.
3. Install the correct counter balance weight in the in the pocket cover for the corresponding knife holder.
Different size holders require different size counter weights. Use Loctite 263 (red) on counter balance
bolts. Torque to 80 ft.-lbs. (108 Nm). Always bolt the counter balance weight as close to the cover mount
as possible. Bolt size is 1/2” - 13 NC x 1 1/2” (12.7mm x 38mm).
4. Bolt the covers to there corresponding pocket. Use Loctite 243 (blue) and torque to 280 ft.-lbs. (380Nm).

! DANGER
Replace the bolts, nuts, knives, clamps and holder when they need it. DON’T stretch it! You will pay for
it either by damage to machine or possible damage to a person. Knife pocket bolts should be replaced after
(5) uses.
Using a piece of wood, install the sharp babbitted knife and hold it firmly into position. The piece of wood
will hold the knife back into pocket.
To retighten the knife clamp; first tighten center knife bolt and then tighten the outside bolts. Knife bolts
must be torqued tight at 210 ft.-lbs. (285 Nm). See instructions on previous page.
Always check with a .002 to .005 feeler gauge to make sure the knife, counter knife and clamps are
seated tight at all seams when done. There should not be any gap between the knife pocket pinch points in
hardware.
To remove the dull knife, hold the knife in position carefully with proper hand protection. Then remove the
bolts with a 6-point socket. Clean all debris out of the knife pocket and hardware.

! WARNING
Refer to the Material Safety Data Sheet (MSDS) for information pertaining to the knife babbitt material
including the health hazard information, first aid procedures, special handling procedures, disposal procedures,
etc. If needed, contact your nearest dealer or Bandit Industries for the knife babbitt MSDS.

KNIFE BABBITTING PROCEDURES

1. Insert the knives into the knife gauge and slide the spacers up tight to avoid overspill of the babbitt material.
2. Heat the knife and knife gauge with a torch (see Figure 1). This will prevent blow back which could occur
if there were any moisture left in the fixture.
3. Pour babbitt slowly from the ladle on to knife gauge between steps gradually filling the cavity (see Figure 2).
4. Once the babbitt has cooled remove the knife (see Figure 3) and place on a stand so the excess babbitt
can be filed away (see Figure 4). Do not allow the babbitt to extend over the edges of the knife or serious
damage will result to the components in the knife pocket.

REMOVING AND REPLACING THE AUGERS

1. To remove the auger assemblies you must follow the instructions on page 89, to split the infeed bed.
2. Unbolt the auger assembly by loosening and removing the bolts at the auger­­flange.
3. Carefully lift up and out to remove the auger ­assembly.
4. When installing an auger place it back in place by putting the 2 flanges together. Make sure that you are
installing the same direction auger as you took out, refer to page 81.
5. Before aligning the bolt holes follow the­­­
instructions on page 81 to time the auger
assembly with the other augers on each side.
There is an alignment pin on the flange to help
in setting the augers in the correct orientation.
6. Assemble the bolts and apply Loctite 263 (red),
tighten, and torque to 110 ft.-lbs. (149 Nm)
7. Return the infeed bed assembly by following the
instructions on page 89.

AUGER TIMING PROCEDURE

The following will instruct on the proper procedure for timing the augers. Augers which are not timed
correctly will not move material properly and will interfere with each other during operation. This interference
will cause auger damage and premature wear.
1. Rotate the augers to “time” each one so that the flighting is centered between the flighting of the auger
on each side. See Example 1.
Example 1

LEFT HAND AUGER RIGHT HAND AUGER

When looking at the auger flighting and the direction

is going up and to the left, it is a left hand auger. When
looking at the auger flighting and the direction is going up
and to the right, it is a right hand auger.

2. Install the auger chain by threading it over the auger sprockets. See Example 2.

4. Remove tools and equipment from the auger area and verify that all persons are clear of the machine.
5. Follow start-up procedures and operate augers to verify timing, sprocket alignment and chain rotation.
6. Tighten the auger chain. There must be 1/4” (6 mm) of sag between the idler sprockets.
7. Check chain tension after several hours of operation and adjust as necessary.
8. Check auger drive sprocket bushing bolt, and drive motor sprockets torque to 30 ft-lb. (41 Nm).

SCREEN REPLACEMENT
• Various screens are available for sizing the product.
• Screens are a wear item on your machine and should be checked frequently.
• IF SCREENS ARE BENT OR BROKEN, REPLACE IMMEDIATELY. FAILURE TO DO SO WILL CAUSE
COSTLY DAMAGE TO YOUR MACHINE.
• When maintaining the screens, ALWAYS adjust the screen to at least 1/4” (6.4mm) from the newest tooth
on the cutterhead (This will tend to be a brand new tooth). If not properly adjusted it will increase wear
inside the grinding chamber.
• Check the screen holder bolts and Nord-Lock washer are at torques to 375 ft.-lbs.(508 Nm).

NOTICE Replacing the screen is a two man operation.

1. The discharge belt conveyor must be folded down to it’s normal operating position and the gate in the
closed position and against the stops.
2. Before attempting any type of maintenance, disengage clutch, wait for the cutterhead to come to a
complete stop, turn off engine, remove the ignition key, make sure the ignition key is in your possession,
wait 2 minutes and then disconnect the battery.
3. At the mill door located on the left side of machine, pull the engine disable plug and release the door
latches and swing the mill door open.
4. Retrieve the electric winch control tether from the tool box and plug it into the receptacle under the
engine. The winch will work with the battery disconnect off.
5. Lower the winch and connect it to the lug on the back of the screen and bring it up snug.
6. Remove the eight mounting bolts and spacer blocks that hold the screen in place.
7. Bring the screen out through the mill door opening with the assistants help.
8. Retrieve the electric screen changing arm control tether and plug it in to the receptacle located outside
the compressor cover.
9. Turn the screen hoist / air compressor disconnect switch to the on position. It is located by the screen
changing arm.

diameter mates with the inside diameter of the gate and the two edges are flush. Make sure the screen
and the gate are in the closed position against the stops.
14. Reinstall the eight mounting bolts and spacer blocks that hold the screen in place.
15. With a new cutter tooth on each end of the cutterhead, set the screen to a minimum of 1/4” (6.4 mm)
from the cutter teeth.
16. Work back and forth and side to side when tightening the bolts. This will keep the screen from pulling
out away from the teeth.
17. When the final adjustment is completed, torque bolt to 375 ft.-lbs (508 Nm).
18. Very carefully, manually with a pry bar or wood bar, turn the cutterhead a full revolution backwards
to make sure there is no contact between cutter teeth and screen.
19. Reinstall the cable hole plug before reeling in winch cable. The cable hole plug must pull tightly to engine
base when complete

GATE REPLACEMENT
! WARNING Replacing the gate is a two man operation due to the fact
of it’s weight and size.

1. The discharge must be in it is normal operating position and the gate needs to be slightly open to take
pressure off the stops. This will make it easier to remove the hinge pins and cylinders.
2. Before attempting any type of maintenance, disengage clutch, wait for the cutterhead to come to a
complete stop, turn off engine, remove the ignition key, make sure the ignition key is in your possession,
wait 2 minutes and then disconnect the battery.
3. Remove the gate indicators from both sides of the machine that show the gate position.
4. At the mill door located on the left side of the machine(curb side), pull the engine disable plug, release
the latches and swing the door open.
5. Retrieve the electric winch control tether from the tool box and plug it into the receptacle under the
engine. The winch will work with the battery disconnect off. The winch has it’s own disconnect switch.
6. Lower the winch and connect it to the gate and bring it up snug.
7. Remove the pins connecting the cylinders to the gate.
8. On the left side of the machine, pull the spring loaded latch and remove the gate pin out using the slide
hammer provided with the machine.
9. Open the access door on the belt shield then release the spring loaded latch to pull the pin.
10. Once the hinge pins are out, the gate can be pulled out and brought out through the mill door opening.
11. Retrieve the electric screen changing arm control tether and plug it in to the receptacle located outside
the compressor cover.
12. Turn the screen hoist / air compressor disconnect switch to the on position. It is located by the screen
changing arm.
13. Hook on to the gate with a chain and hook the chain onto the hook provided at the end of the screen
changing arm.
14. Lift the gate and swing the screen changing arm away from the machine and lower to the ground.
15. Install the new gate using the screen changing arm and a chain to position it through the mill door then
use the winch to move it into place.
16. After the new gate is in place, start the hinge pin from the left side and drive it through until it stops. Be
sure to align key stock with gate bushing slot.
17. Start the hinge pin from the right side and drive it through until it stops. Be sure to align key stock with
gate bushing slot.
18. Release the spring loaded latch.
19. Reconnect the hydraulic cylinders to the gate.
20. Check the clearance between the gate and the new tooth. If adjustment is needed, loosen bolts on lower
cylinder lug mounts, adjust and retighten.
21. Very carefully, manually with a pry bar or wood bar, turn the cutterhead a full revolution backwards. This
is to ensure the cutter teeth have proper clearance.
22. Reinstall the indicators on both side of the machine.
23. Close and secure the mill door and finally reinsert engine disable plug or the engine will not start.
24. Start the engine and operate the manual control valve to open and close the gate, checking for proper
operation.

NOTICE
The gate must be closed while grinding, unless foreign objects need to be let out. The machine can be run
with the gate 1/3 open, but not completely open for long periods of time. Running the machine with the gate
1/3 open will direct the material to the ceiling of the cutterhead chamber, which will not allow the material to
fall directly on the discharge and shorten the life of the discharge. The metal can be removed upon discharge
from the discharge belt conveyor. The material can then be reprocessed with the gate closed.

PAINT CARE
To help keep up the appearance of your Bandit equipment and reduce the possibility of surface rust follow
these steps:
1. The machine should be washed on a regular basis with a non-abrasive mild detergent and then rinsed
thoroughly. Do not pressure wash sensitive areas like: decals, gauges, electronic devices, autofeed
control, etc.
2. If a stone chip, paint scratch, or paint crack occurs - it should be repaired immediately. Simply sand the
edges of the damaged paint area, mask off the surrounding area, and apply primer and paint to the dry,
clean, and warm area. This will keep the damaged area from spreading or getting worse.
3. If you are unable to sand and mask the area, there are containers of primer and paint available. A small
brush can be used to touch up the area.
4. Also, primer and most colors of paint are available in aerosol spray cans to simply spray over the effected
area after it is cleaned, dry, and warmed. This method is not as reliable as the process in step #2.
It is also reported that some equipment owners polish their machine at least yearly, and keep good mud flaps
on their towing trucks.

! WARNING
CHECK FOR FIRES, CLEAN OFF DEBRIS,
SWITCH OFF BATTERY
DO NOT leave this machine unattended until all potential fire debris
is removed, no fire or smoldering exists and battery is switched off. The
diesel engine creates many hot spots, including exhaust manifold and
turbo. Remove all flammable debris (wood, mulch, oils, fuels, etc.) from:
• Engine turbo and exhaust • Inside and around (including behind) the belt shield
• Beside and around engine • Inside control cabinets
• Under engine and tanks • Anywhere materials collect
DO NOT leave this machine unattended until all fire hazards are
removed, hot spots are cold and battery is disconnected.
DO NOT leave machine unattended unless it has been relocated away
from flammable material.
ALWAYS keep several type A:B:C fire extinguishers operational and on
the job at all times.

RECOMMENDED BRAKE ADJUSTMENT PROCEDURE PER AXLE MANUFACTURER.

The proper clearance between the shoe and drum surfaces will be set up initially from our factory to assure
proper operation during the normal break in period. No further adjustment will be necessary until the vehicle
completes the recommended break in period of 200 miles (322 km).
Since all brakes of this type must be burnished or “run in” before their full effectiveness can be achieved, the
MFG. maintenance manuals call for readjustment after the first 200 miles (322 km) of operation. This usually
allows ample time for the burnishing to take place. Readjustments are not necessary for brakes fitted with
self-adjustment features although periodic inspection is suggested.

NOTICE
Clearances that are too small will result in excessive drag and overheating while too much clearance
can render the brake nonfunctional.

HYDRAULICS
! WARNING
It is very important after you have operated a new machine for approximately an hour to shut down the machine
and recheck all hydraulic fittings. Relieve all pressure and retighten as needed.
DO NOT GO NEAR HYDRAULIC LEAKS! High pressure oil easily punctures skin causing serious injury, gangrene,
or death. Avoid burns from fluid. Hot fluid under pressure can cause severe burns. DO NOT use fingers or skin to
check for leaks. Lower load or relieve hydraulic pressure before loosening fittings. Relieve all pressure in the system
before disconnecting the lines, hoses, or performing other work. Use a piece of cardboard to find leaks. Never use
your bare hands. Allow system to cool down to ambient temperature before opening any coolant or hydraulic oil
system.
In cold weather situations let your hydraulic system idle for approximately 15 minutes to allow the system to warm
up to operating temperature.

! WARNING
DO NOT operate this machine unless all hydraulic control devices operate properly. They must function,
shift and position smoothly and accurately at all times. Faulty controls can cause personal injury!

HYDRAULIC FLUID REQUIREMENTS

This machine is equipped with “Petro-Canada Hydrex XV” hydraulic fluid. It is recommended to replace with
the same. “Petro-Canada Hydrex XV” is an all season hydraulic fluid. This is a premium performance, long
life anti-wear, hydraulic fluid, designed for all season use in heavy duty hydraulic systems. “Petro-Canada
Hydrex XV” allows year round use under wide extremes of temperature. It allows the hydraulic system to
start at temperatures as low as -40°C/-40°F, under no load conditions and it improves lubrication of hydraulic
components at high operating temperatures. It will also help protect against hydraulic failures during the
wide temperature swings of spring and fall. To find the closest “Petro-Canada Hydrex XV” dealer call
1-888-284-4572.
Multi Viscosity motor oils are not recommended to mix with “Petro-Canada Hydrex XV” hydraulic oil. AW oils
may mix with “Petro-Canada Hydrex XV” hydraulic oil. The following are specifications and authorizations of
compatible oils. Only a high quality anti-wear (AW) hydraulic oil containing foam, corrosion, rust and oxidation
inhibitors should be used. This viscosity grade depends on the oil temperature in service, based on the climate
and operating conditions.

NOTICE
The above chart is a suggested guide for viscosity of hydraulic fluids at start up ambient temperature.
The load, demand, and cleanliness of the equipment will affect actual oil temperatures which can
increase dramatically above ambient air temperatures during operation. The actual viscosity needed is
based on oil temperature during operation and not air temperature. Compare your fluid specifications with
the specifications below to verify compliance.

When choosing a hydraulic fluid - these maximum and minimum specifications must be met:
Minimum Viscosity during operation = 12 cSt
Maximum No-Load Viscosity at start-up = 2000 cSt

Hydraulic fluids vary in their resistance to oxidation at elevated temperatures, their ability to protect
against metal-to-metal contact under increasing temperature, and their ability to separate water from
the fluid. Viscosity is temperature dependent. Fluids with high viscosity-index (VI) will thin out slower
at higher temperature and thicken slower at colder temperatures allowing a wider operating range.
Choose a fluid that has test results in these areas for best results.

Based on the varying temperatures of the area where Bandit equipment is used, and the high demand
and loads placed on this equipment, Bandit has filled each hydraulic system with Petro-Canada’s Hydrex
XV All Season Hydraulic Fluid for maximum protection and performance.

Go to: lubricants.petro-canada.com to find a dealer near you.

NOTICE
Some component manufacturers require different specific lubrication requirements, such as gear boxes,
undercarriage drives, fluid engagement clutches, etc. Refer to the manufacturer’s manual for information.

HYDRAULIC FLUID FOR “PT TECH” CLUTCH

If machine is equipped with a “PT Tech” hydraulic clutch, the clutch must use “Mobil” Fluid #424, per c­ lutch
manufacturer’s recommendations. Refer to clutch manufacturer’s manual for more information, inspection,
and service.

RECOMMENDATIONS:
We recommend running a minimum of 30 fan teeth in most applications. The fan teeth will help move the ground
material through the screen quicker than standard teeth. This will help to reduce wear and increase production
while grinding.
