SERVICE & MAINTENANCE
WARNING
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE, DISENGAGE THE
HYDRAULICS, OPEN SHIELD AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
Feeding too large or too much material at once may plug
the chipper. To clear a plugged rotor, proceed as follows:
1.
Turn off engine key switch. Allow all moving parts to
come to a complete stop. Lift engagement handle.
2. Remove the two 3/8" retaining bolts holding the access
cover to the chipper frame and lift up access cover.
3.
Remove the lock pin from storage position (see
Figure 5.5).
4.
Turn check valve clockwise to engage the jack pump.
5. Pump the handle to raise the feed roller until the lock
pin position aligns with one of the support bracket
holes.
6. Secure the position by putting the lock pin through the
support bracket and lock pin position.
7. Clean the debris away from the chipper rotor. Turn
the rotor by hand to be sure it is free to rotate. Be
careful to avoid the chipper blades when cleaning out
the debris.
8. Remove the lock pin and put it back in storage
position.
LEAVING THE LOCK PIN IN ANY OTHER
POSITION MAY INTERFERE WITH FEED ROLLER
OPERATION.
If the machine becomes plugged, lift the engagement
handle, shut off the engine, disconnect the spark plug
wire and allow the machine to come to a complete stop
before clearing debris. Do not operate the machine
without proper guards and shields in place.

to the frame.
3. Measure the amount of clearance between chipping
blades and chipping anvil from inside of housing.
Adjust both rods of the anvil spacer to achieve a
uniform gap.
4.
Raise the feed roller (see Figure 5.5). Install anvil
spacing gauge (see Figure 5.4).
5. Check clearance on all the blades. Remove anvil
spacing gauge.
6. Tighten bolts on chipping anvil to 75 ft-lbs and resume
operation.
7. If chipping anvil edge is damaged or worn unevenly,
remove the three bolts holding the anvil and use one of
the other three edges. Adjust for correct measurement.
When all four edges have been used, replace anvil.
