IMPORTANT
Polyurea and lithium-based greases are not compatible.
Mixing the two grease types may lead to premature
failure.
NOTE
Do not over grease bearings. Overfilling can lead to
excessive heat and/or unseating of the seals. Add
grease slowly and under light pressure. Whenever
possible, rotate bearing slowly while lubricating.
5.6 SETTING CHIPPING BLADE CLEARANCE
1. Loosen and remove the 3/8” carriage bolt securing the
knife access cover.
2. Open the knife access cover exposing the chipper
shredder compartment.
3. Remove the dust cover on the front side of the machine.
4. Remove the belt guards on the rear of the machine.
5. Loosen the set screws holding the lock collars on the
front and rear 2-bolt flange bearings.
6. Use a punch and hammer to tap the lock collars directly
opposite normal rotation. (On the front side, tap punch
in a CW rotation. On the rear side, tap punch in a
CCW rotation
7. Using a rubber mallet, tap the end of the rotor shaft to
obtain 1/16” to 1/8” clearance. Rotate the rotor and
check the clearance on all chipping blades.
The chipping blades should clear the anvil by 1/16" but
not more than 1/8". Check the clearance every 8 hours
of operation and adjust if needed. The chipping anvil
is reversible. All four sides of the anvil can be used for
chipping.
To adjust the anvil:

grease. Extreme working conditions will require more
frequent greasing.
Grease the following points every 50 hours of operating
time:
