4.4 CHIPPING
1. Select limbs that are between 3/4 and 5 inches in
diameter; trim side branches off that cannot be bent
over enough to fit into the chipper chute. Some small
branches can be broken off on the chipper chute
transport handle. Small diameter branches can be
held together in a bundle and fed in simultaneously.
2. Place limb, butt end first, into the chipper chute until
it contacts the chipping blades. The actual feed rate
of the limb into the chipper will depend on the type of
material being fed, the sharpness of the cutting
blades and the size of the machine. Alternately insert
and retract the limb or insert continuously at a rate
that will not kill the engine. Rotating the branch as it
is being fed will improve cutting action.
3. The chipping blades will dull with use and require
periodic sharpening. Refer to the Service and Mainte-
nance section for instructions.
Operation
Due to the aggressiveness of the machines chipping
capacity, do not attempt to hold on to material
intended for chipping once it has been placed in the
chute.
WARNING
4.5 STOPPING (TOWABLE MODELS)
To stop the machine, proceed as follows:
1. Move throttle to slow position.
2. Disengage rotor clutch by pressing foot pedal.
3. Move throttle to stop position or turn off ignition switch
and remove spark plug wire from spark plug.
4. Allow machine to come to a complete stop.
4.6 STOPPING (PTO MODELS)
1. Move the tractor throttle to slow position.
2. Disengage the PTO lever and shut off the tractor
engine.
3. Allow the machine to come to a complete stop.
The rotor is heavy and has inertia that will make the
rotor continue to turn for some time after the clutch
has been disengaged. You can tell that the rotor has
come to a complete stop when there is no noise,
machine vibration, or the exposed end of the rotor
shaft is not rotating. The stopping time can be
shortened by inserting a branch into the chipper chute
so it contacts the blades and slows the rotor.
