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 the engagement handle.
If the machine becomes plugged, lift the engagement
handle, shut off the engine, 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.
WARNING
1. Check wheel bolt torque monthly.
2. Check air pressure in tires monthly.
3. Check and repack wheel bearings with grease every
12 months.
4. When towing, always connect the safety chains.
Make sure trailer hitch bolts are tight.
5. Check trailer lights periodically.

The chipping blades should clear the chipper block
located directly under the chipper chute by 1/16 to 1/8".
To adjust the blade clearance, proceed as follows:
1. Open access cover (see Section 5.3) to allow access
to anvil. See Figure 5.4 for anvil location.
2. Loosen the three 1/2" bolts that hold the chipper anvil
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 5.6). Install anvil
spacing gauge (see Figure 5.5).
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.
