4.5 CHIPPING
Operation
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 ma-
terial. Adjust engine speed with the
throttle. On diesel models the
throttle can be locked.
2. Select limbs that are up to 6 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
chute, rather than from the front.
Step aside to avoid being hit by the
brush moving into the chipper.
4. Never lean over the 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 chip-
per and cause major damage. In ad-
dition, metal pieces can come back
like shrapnel to injure or kill.
6. Never push brush into the chute with
your feet.
7. Engage the hydraulic feed by mov-
ing the control arm. Pull the arm
toward you to engage the hydraulic
feed. The speed of the feed roller
can be adjusted by turning the speed
control knob on the chipper valve as-
sembly.
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.
9. If the feed roller slips downward pres-
sure on the roller can be increased
by moving the eyebolt that connects
the spring to the feed roller.
10. Alternate greener material with dry
material to lubricate the chipping
blades for longer life and better per-
formance. When the chipping blades
become dull, they will require peri-
odic sharpening. Refer to Service
and Maintenance, "Sharpening Chip-
per Blades."
Obtain and wear safety glasses at
all times when operating the ma-
chine. Do not wear loose fitting
clothing. Use common sense and
practice safety to protect yourself
from branches, sharp objects and
other harmful objects.
