Operation
3. The controller will also flash service alerts when started.
Every 15 hours it will flash (error light blinks 5 times) to
sharpen the chipper blades. Every 100 hours it will flash
(error light blinks 10 times) to change the engine oil. To
reset service alerts, locate light green wire in engine com-
partment next to the hour meter. Connect green wire to
red wire connector for five seconds.
NOTE: The RPM sensor on the rotor must flash or the
controller won’t work. Clearance between the sensor and
the bolt must be between 1/32” and 3/32”.

4.5 CHIPPING
The Bear Cat chipper chips a variety of materials into a
more readily decomposing or handled condition. Use the
following guidelines to help 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. Before chipping material, engage the unit to full operating
speed. Adjust engine speed with the throttle. Diesel mod-
els have the option of locking the throttle.
2. Select limbs up to 6 inches in diameter. Trim side
branches that do not bend enough to feed into the chip-
per chute. Hold small diameter branches together in a
bundle and feed 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 mov-
ing 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 chipper and cause major damage. In addi-
tion, 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 moving the control arm.
Pull the arm toward you to engage the hydraulic feed.
Adjust the speed of the feed roller by turning the speed
control knob on the chipper valve assembly.
8. Place limb, butt end first, into the chipper chute until it
contacts the hydraulic feed roller and draws into the chip-
per blades. The actual feed rate of the limb into the chip-
per will depend on the type of material fed, and sharp-
ness of the cutting blades.
9. If the feed roller slips, increase the downward pressure on
the roller 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 performance.
When the chipping blades become dull, they will require
periodic sharpening. Refer to Service and Maintenance,
"Sharpening Chipper Blades."
Obtain and wear safety glasses at all times when oper-
ating the machine. Do not wear loose fitting clothing.
Use common sense and practice safety to protect your-
self from branches, sharp objects and other harmful ob-
jects.
