4.7 CHIPPING GUIDE
The Crary Bear Cat chips a variety of materials into a more readily
decomposed or handled condition. The following guidelines can
help you get started.
Run unit at full operating speed before starting to chip
material.
Select limbs that are up to 4-1/2 inches in diameter. Trim
side branches that cannot be bent enough to feed into the
chipper chute. Hold small diameter branches together in a
bundle and feed in simultaneously.
Exclude pieces of metal, rocks, bottles, cans, and other
foreign objects when feeding chipable material into the
machine.
Feed brush from the side of the chipper chute, rather than
from the front. Step aside to avoid being hit by the brush
moving into the chipper.
Do not lean over the chipper chute to push objects into the
cutting device. Use a push stick or brush paddle.
Never use shovels or forks to feed brush. They can be
chipped, are expensive to replace, and cause extensive
damage. In addition, metal pieces can be ejected from the
chipper chute and cause serious injury or death.
Never feed brush into the chipper chute with your feet.
Place limb, butt end first, into the chipper chute until it con-
tacts 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.
Stop the material feeding and allow the engine to recover if
the engine slows to where it may stall.
Remove the branch and rotate it before reinserting it into the
chute if the chipper jams.
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 green material with dry material to lubricate the
chipping blades for longer life and better performance.
The chipping blades will become dull and will require periodic
sharpening. Refer to the Service and Maintenance section
for sharpening instructions.

WARNING
Allow the machine to come to complete stop before
inspection or servicing. The rotor is heavy and has inertia
built up that will allow the rotor to turn for some time after the
clutch has been disengaged. You can tell when the rotor has
come to a complete stop when there is no noise or machine
vibration present. You can reengage the clutch to slow the
rotor to a stop.
4.6 STOPPING PTO MODELS
If the tractor is able to stop the chipper with the chipper en-
gagement lever in the CHIPPING position, it is not required
to place the chipper engagement lever in the START position
when stopping the tractor PTO. If the tractor PTO cannot
stop the chipper with the chipper engagement lever in the
CHIPPING position, move the chipper engagement lever to
the START position.
Move the tractor throttle to the SLOW position.
Disengage the PTO lever and shut off the tractor engine.
Allow machine to come to a complete stop.

4.4 CONNECTING THE PTO SHAFT
Move the machine to a clear, level area outdoors before starting.
Do not operate in the vicinity of bystanders. Make sure the cutting
chamber is empty before starting.
Connect the PTO shaft between the chipper and the tractor. The
minimum & maximum telescoping on the PTO shaft is 18.11" to
24.49".
