2.3.3 Chipping
Warning: 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!
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.
1. Be sure the unit is at full operating speed before you
start to chip material.
2. Select limbs that are up to 4 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. 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. Place limb, butt end first, into the chipper chute
until it contacts 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.
8. If the engine slows to where it may stall, stop the
material feeding and allow the engine to recover.
9. If the chipper jams, 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.

the starter cord until light resistance is felt and then
pull briskly.
4. As the engine warms, gradually move the choke
lever to the OPEN position.
5. Slowly release foot pedal to engage chipper.
2.3.2 Starting Instructions: PTO
Models
Caution: This chipper is designed to be used
with tractor PTO's rated at 15 to 40 horsepower.
Using this chipper with PTO's above 40 horsepower
may cause belt and machine damage in overload
conditions.
1. Place tractor transmission in neutral and set parking
brake. Connect 3 pt. mounts between the chipper
and the tractor. Secure connections with snap pins.
Adjust 3 pt. top link so that chipper sits level.
2. Connect PTO shaft to tractor. Make sure you are
using the correct RPM machine.
3. Never inspect or work on PTO drive area without
first disengaging PTO and shutting off tractor
engine.
4. Start tractor engine and engage PTO drive clutch
(refer to tractor owner's manual). Increase speed to
rated PTO RPM position.
