Do not leave machine unattended, or attempt any inspection

from key switch.
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.
• Run unit at full operating speed before starting to chip material.
• 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 simultaneously.
• 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.
• 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 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.
• Never push brush into the chipper chute with your feet.
• 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.
• 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 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."
