Page 17 5" Chipper W/Hyd. Feed Owners Manual
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. Run unit at full operating speed before starting to chip
material.
2. Select limbs that are up to 5 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 fed in simulta-
neously.
3. Feed brush from the side of the chipper chute, rather
than from the front. Then, step aside to avoid being
hit by the brush moving into the chipper.
4. Do not lean over the chipper 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
be chipped, are expensive to replace, and cause
extensive damage. In addition, metal pieces can
come back to injure or kill.
6. Never push brush into the chipper chute with your
feet.
7. 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.
8. Stop the material feeding and allow the engine to
recover if the engine slows to where it may stall.
9. Remove the branch and rotate it before reinserting it
into the chute if the chipper jams.
10. Alternately insert and retract the limb or insert
continuously at a rate that will not kill the engine.
11. Chipping dead, dry material will create heat and dull
the chipping blades quickly.
12. Alternate greener material with dry material to
lubricate the chipping blades for longer life and better
performance.
13. When the chipping blades become dull, they will
require periodic sharpening. Refer to Service and
Maintenance, "Sharpening Chipper Blades."
