Service & Maintenance
WARNING
If the machine becomes plugged, shut off the skid steer
engine, disconnect the hydraulics, remove ignition key,
and allow the machine to come to a complete stop before
clearing debris. Do not operate machine without proper
guards and screens in place.
CLEANING PLUGGED ROTOR
Cleaning the Rotor:
1. Stop skid steer engine, disengage hydraulics, and allow
machine to come to a complete stop.
2. Position the chipper chute to the side of the chipper.
3. Remove the two bolts on the chipper housing.
4. Tip the chute and housing away from the chipper to ex-
pose the rotor and the blades.
5. Clean the debris out of the chipper. Turn the rotor by hand
to be sure it is free to rotate. Check for damage to the
rotor.
6. Close the top housing.
7. Reattach the two bolts securing the chipper housing.
8. The machine is ready for operation.
Cleaning the Feed Roller:
A bottle jack is mounted on the chipper to raise the feed
roller. This allows plugged debris to be easily removed from
the roller if the reverse function fails to dislodge the debris.
To operate the jack:
1. Turn the 1/2” wingnut located on the bottom of the jack to
the right, engaging the jack.
2. Using the jack handle pump the jack, connected to the
feed roller, to the desired location.
3. Clear the unit of debris. Do not place hands underneath
the feed roller.
4. Once the debris has been cleared release tension on the
jack by turning the 1/2” wingnut to the left and lowering
the feed roller.
5. Before operation turn and tighten the 1/2” wingnut fully to
the right.
