CLEARANCE
The four chipping blades should clear the chipping anvil by
3/16" + 1/16". If damage or uneven wear occurs on chipping anvil
edge, replace the anvil. To adjust the blade clearance:
Raise and secure the feed roller (Section 4.7).
Lift the rotor cover and secure with the lockup pin (Section
4.4).
Rotate the disk until a chipping blade is even with the
anvil.
Secure the disk to prevent movement during adjustment.
Loosen the three 1/2" x 1-1/2" bolts that secure the anvil to
the chipper housing.
Loosen the two 3/8" adjustment nuts located inside the
anvil backplate.
Tighten both 3/8" x 3-1/2" bolts equally to adjust the anvil.
Measure the clearance between the chipping blade and the
anvil from inside the feed chute. Continue to adjust both
bolts equally until there is a minimum 3/16" + 1/16" clearance
between the chipping blades and anvil.
Remove the disk lock and rotate the disk to ensure there is
proper clearance between all four chipping blades and the
anvil; insert disk lock and adjust anvil if necessary.
Once proper clearance is achieved, tighten the three
1/2" x 1-1/2" bolts to secure the anvil to the frame.
Tighten the two 3/8" adjustment nuts located inside the
anvil backplate.
Remove the disk lock and lower the rotor cover.
Remove the lockup pin, lower the feed roller and resume
operation.

DANGER
Ensure that the feed roller is raised and secure before entering
the feed chute. Failure to do so can result in serious injury
or death.
5.5 CHECKING/ADDING COOLANT
The chipper is tested before shipping. In order to test the
equipment, the fluid levels are filled. However, before starting
the machine, check the coolant level in the radiator and coolant
reserve tank (if equipped) to ensure it is with in the proper
operating range (between FULL and FILL). Refer to the engine
owner's manual for specific instructions on checking and adding
coolant.
5.4 REPLACING THE DRIVE BELT

the drive belt:
Remove the four 3/8" x 1" bolts, washers and nuts secur-
ing the PTO shield to the chipper housing and remove the
shield.
Remove the four 7/16" x 1-1/2" bolts and washers attaching
the PTO shaft to the drive shaft adapter; remove the adapter
from the lower belt sheave (Figure 5.3).
Remove the 7/16" 1-1/2" bolt, washer, nut and spacers
securing the idler pulley to the belt idler weldment; remove
the pulley.
Remove the drive belt and install the new belt.
Reattach the idler pulley.
Slide the drive shaft adapter onto the lower belt sheave and

If the anvil edge is damaged or worn unevenly, remove anvil
and use one of the other three edges. If all edges are damaged

Coolant is hot during and after operating chipper. Do not check
coolant level when fluid is hot. Wait until the fluid has cooled
before removing radiator cap.
