to full speed.
9. If the chipper jams, reverse the feed by moving the
control arm in the reverse direction. Remove the
branch and rotate it before reinserting it into the chute.
Alternately insert and retract the limb or insert
continuously at a rate that will not kill the engine.
Chipping dead, dry material will create heat and
dull the chipping blades quickly. Alternate greener
material with dry material to lubricate the chipping
blades for longer life and better performance. When
the chipping blades become dull, they will require
periodic sharpening. Refer to Service and Mainte-
nance, "Sharpening Chipper Blades."
Stopping Instructions:
1. Move throttle to slowest position.
2. Depress foot clutch pedal.
3. Turn key switch to off position.
4. Allow machine to come to a complete stop. Release
the foot clutch pedal to help slow the rotor once the
engine has stopped running.
NOTE: The heavy rotor will continue to turn for some
time after the engine. You can tell that the rotor has
stopped when no noise or machine vibration is present.
WARNING: Do not leave machine unattended, or
attempt any inspection or service unless the engine is
stopped and the key is removed from key switch.
2.4 Chipping
The Bear Cat chipper is designed to chip a variety of
materials into a more readily decomposing or handled
condition. The following guidelines can be used to help
you get started.
Please read and follow all safety instructions in
this manual. Failure to operate the chipper in
accordance with the safety instructions MAY RESULT
IN PERSONAL INJURY!
1. Be sure the unit is at full operating speed before you
start to chip material.
2. Select limbs that are up to 9 inches in diameter.
Trim side branches that cannot be bent enough to
feed into the chipper chute. Small diameter
branches can be held together in a bundle and fed in
simultaneously.
3. Feed brush from the side of the infeed chute, rather
than from the front. Then, step aside to avoid being
hit by the brush moving into the chipper.
4. Never lean over the infeed chute to push objects
into the cutting device. Use a push stick or brush
paddle.
5. Never use shovels or forks to push brush. They can
go through the chipper, are expensive to replace and
cause major damage. In addition, metal pieces can
come back like shrapnel to injure or kill.
6. Never push brush into the infeed chute with your
feet.
7. Engage the hydraulic feed by moving the control
arm. Pull the arm toward you to engage the hydrau-
lic feed (see figure 2.9). In the forward direction,
the feed rate increases as the arm is moved.
8. Place limb, butt end first, into the chipper chute
until it contacts the hydraulic feed roller and is
drawn into the chipper blades. The actual feed rate
of the limb into the chipper will depend on the type
of material fed, and sharpness of the cutting blades.
If the engine slows to where it may stall, push the
control lever inwards to slow or stop the material
feeding and allow the engine to recover. Pull the
lever out to restart feeding when the engine is back
