MODEL 75 MAINTENANCE
ANVIL ADJUSTMENT
CHECK THE ANVIL TO KNIFE CLEARANCE
Do not under any circumstance attempt to rotate
the chipper disc while someone is inside the infeed
hopper. This will cause serious injury.
The anvil hardware must be replaced every time
the anvil is replaced to ensure proper clamping
ability.
ANVIL ADJUSTMENT PROCEDURE
DANGER
Before attempting any type of maintenance,
disengage clutch, wait for the disc to come to a complete
stop, turn off engine, remove the ignition key, make
sure the ignition key is in your possession, install the
disc lock pin, and disconnect the battery.
Before working inside the infeed hopper or under
the top feedwheel remove the yoke springs from the
top yoke, raise the yoke , install the yoke lock pin,
safety chain the yoke in the raised position, and
insert a wooden block to assist in holding the yoke in
the raised position. Failure to this will cause serious
injury.
1. This clearance should be checked on a weekly
basis or as knives are changed. To check the
anvil clearance, follow all pre-maintenance shut
down procedures. Once all safety procedures
are completed the anvil to knife clearance can be
checked.
2. In order to check the clearance one person will
need to climb into the infeed hopper. Use a feeler
gauge or the anvil to knife gauge supplied by Bandit
to check the clearance of the first knife to the anvil.
Check the clearance at the left and right sides of
the knife.
3. Once that knife has been checked climb back
out of the infeed hopper, remove the disc lock pin,
and very carefully rotate the chipper disc so the other
knives can be checked.
4. Once all knives have been checked adjust the
anvil according to the closest knife. The anvil to
knife clearance should be .110” to .120” (2.8 mm
to 3.0 mm).
5. Set the closest knife to this distance.
1. To adjust the anvil first loosen two of the hex
nuts on either the inside or outside of the anvil puller
block. If the anvil needs to be adjusted closer to the
disc, loosen the outside anvil adjuster hex nuts. If
the anvil needs to be adjusted away from the disc,
loosen the inside anvil adjuster hex nuts.
2. Loosen the anvil bolts from underneath the
machine.

3. Once the components have been loosened,
move the anvil to the correct clearance using the
anvil adjuster bolts and hex nuts.
4. Once the knife is set to the correct clearance,
.110” to .120” (2.8 mm to 3.0 mm), retighten all
components.
5. Make sure bolts are torqued to their specific bolt
torques refer to bolt torques on page 24.
6. Carefully rotate the chipper disc to make sure all
the knives clear the anvil.
