ANVIL ADJUSTMENT
Before attempting any type of maintenance
disengage clutch, turn off engine, wait for the drum
to come to a complete stop, install the drum lock pin,
disconnect battery, and make sure the ignition key is
in your possession.
Before working inside the infeed hopper or under
the top feedwheel remove the easy climb 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.
Do Not under any circumstance attempt to rotate the chipper drum while someone is inside the infeed hopper.
They may become seriously injured, Do Not Do This!
Once the drum has been rotated, reinstall the drum lock pin, and then check the clearance between the next
knife. Once all knives have been checked adjust the anvil according to the closest knife. The anvil to knife
clearance should be .120 inches (3.0 mm). Set the closet knife to this distance.
Anvil Adjustment Procedure
(Refer to above Figure)
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 drum, loosen the outside hex nuts. If the anvil needs to be adjusted
away from the drum, loosen the inside hex nuts. Next loosen the anvil clamp bolts from underneath the machine.
Once the components have been loosened, move the anvil to the correct clearance using the adjuster bolts and
hex nuts. Once the knife is set to the correct clearance, .120 inches (3.0 mm), retighten all components. Make
sure bolts are torqued to their specific bolt torques refer to bolt torques on page 41. Carefully rotate the chipper
drum to make sure all the knives clear the anvil.

DANGER
Check the Anvil to Knife Clearance
This clearance should be checked on a weekly basis or as knives are changed. To check the anvil clearance
the above safety procedures must be taken. Once all safety procedures are completed the anvil to knife clearance
can be checked. 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. Once that knife has been checked climb back out
of the infeed hopper, remove the drum lock pin, and very carefully rotate the chipper drum so the other knives
can be checked.
