4.3 STOPPING ELECTRIC MODELS
(77412, 77412S)
1. Move the throttle to the "slow" position.
2. Move the chipper engagement lever to the "start" posi-
tion.
3. Allow the engine to run at idle for 30-60 seconds.
4. Stop the engine by moving the throttle to the "stop"
position or turning off the ignition key.
5. Allow machine to come to a complete stop.
The Bear Cat chipper is designed to chip a variety of mate-
rials into a more readily decomposable condition. The fol-
lowing guidelines can be useful in getting you started.
1. Run unit at full operating speed before starting to chip
material.
2. Select limbs that are up to 4-1/2" inches in diameter.
Trim side branches off that cannot be bent enough to
feed into the chipper chute. Hold small diameter branches
together in a bundle and feed in simultaneously.
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 can cause ex-
tensive damage to the chipper. In addition, metal pieces
can fly out and cause serious injury.
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 chipping blades. The actual feed rate of
the limb into the chipper will depend on the type of ma-
terial being fed and sharpness of the cutting blades.
8. The operator needs to control the rate of feed into the
chipper. Do not place material into the chipper chute
and walk away. This could result in serious injury or
damage to the machine.
9. If the engine slows to where it may stall, stop feeding
the material and allow the engine to recover.
10. If the chipper jams, refer to Section 5.7.
11. Alternately insert and retract the limb or insert continu-
ously at a rate that will not kill the engine. Rotating the
branch as it is being fed will improve cutting action.
12. Chipping dead, dry material will create heat and dull the
chipping blades quickly.
13. Alternate greener material with dry material to lubricate
the chipping blades for longer life and better performance.
14. When the chipping blades become dull, they will re-
quire sharpening (Section 5).
4.5 CHIPPING
WARNING
Allow the chipper to come to a complete stop before in-
spection and servicing. The rotor is heavy and has inertia
built up that will allow the rotor to continue to turn for
some time after the chipper has been disengaged. You
can tell when the rotor has come to a complete stop
when there is no noise or machine vibration present. You
can reengage the chipper engagement lever to slow the
rotor to a stop.
OPERATION
WARNING
Keep face and body away from the feed opening. Do not
overreach. Keep proper balance and footing at all times.
4.4 STOPPING RECOIL MODELS
(77413, 77413S)

2. Move the chipper engagement lever to the "start" posi-
tion.
3. Allow the engine to run at idle for 30-60 seconds.
4. Stop the engine by turning off the ignition switch coun-
terclockwise.
5. Allow machine to come to a complete stop.
