321/21
MODEL 75 MAINTENANCE
Only Bandit knives and hardware are recommended for use in your Bandit chippers. Only then can
you be assured of a quality product that ts and performs the best to the standards of excellence
that is expected from the Bandit chipper.
1. Disconnect the chipper hood engine disable plug.
2. Remove the padlock from the hood pin.
3. Recess the spring lock for the hood pin and
retract the hood pin.
4. Carefully open the hinged part of the chipper
hood. Do not slam the chipper hood to the open
position. This will cause damage to the hinge. If the
hinge becomes damaged by slamming the hood
open, replace the hinge immediately. If the hinge has
become damaged, it will cause misalignment of the
hood, the chipper disc may hit the hood and cause
a serious accident.
5. Changing the chipper knives is a two person
job. One person, using a wooden block, holds the
chipper knife in place while the other person removes
the chipper knife hardware. Typically a 5/16” allen
wrench and a 7/8” socket are required to change or
torque the knife hardware.
6. Once the knives have been removed, inspect
the knife pocket. Check for secure welds, excessive
wear, impact cracks, and elongated bolt holes. If a
problem is found, contact your local dealer or Bandit
Industries.
7. Clean out the knife pocket at this time. Remove
all debris from the pocket and knife bolt holes.
Chipper knives are sharp and can be dangerous.
It is always necessary for your protection to be
extra careful and wear proper hand protection when
handling knives. Before changing knives make sure
all shut down procedures are followed.
KNIFE CHANGING PROCEDURE
Before attempting any type of maintenance,
disengage clutch, wait for the disc to come to a complete
stop, turn o󰀨 engine, remove the ignition key, make
sure the ignition key is in your possession, install the
disc lock pin, and disconnect the battery.
8. Rotate, or replace the chipper knife. Knives must
be professionally sharpened, maintaining angle and
dimensional specications. Knives must be replaced
in sets. These sets are determined by the amount
of resharpening done to the knives. The knife must
be reinstalled with another knife of comparable
usage. It helps to keep the disc balanced, and it
helps maintain chip quality. Do not allow the knives
to wear beyond the absolute minimum specied
distance from the center line of the bolt hole.
Reinstall the chipper knives. Make sure to properly
torque the knife hardware, see page 24. Do not
apply anti-seize to the knife bolts. Knife mounting
hardware must be replaced after a maximum of 5
knife rotations/changes to ensure safe clamping
ability. All knives and knife mounting hardware must
be factory approved.
9. Remove the disc lock pin. Very carefully,
manually with a pry bar or wood bar, turn the
chipper disc to the next knife pocket. Reinstall the
disc lock pin.
10. Repeat steps 6 through 9 for each knife pocket.
11. Once the knives have been changed or rotated,
check the anvil clearance. Make sure the clearance is
maintained to the specied distance from the highest
knife. See anvil adjustment on pages 34 - 35.
Do not under any circumstance attempt to rotate
the chipper disc while someone is inside the infeed
hopper. This will cause serious injury.
12. Close the hinged part of the chipper hood and
reinstall the hood pin, hood pin padlock, and the
chipper hood disable plug.
