The feed roller speed control is used to control the speed
of the feed roller allowing the operator to have better con-
trol of material being fed into the chipper.
For optimum chipping, it is recommended that the feed
roller operate at a faster rate for smaller branches and at
a slower rate for larger branches.

The machine chips a variety of materials into a more
readily decomposed or handled condition. The following
guidelines will help you get started.
Run unit at full operating speed before starting to chip 1.
material.
limbs fed in to the chipper chute must be X inches
2.
(X cm) in diameter or less. Trim side branches that
cannot be bent enough to feed into the chipper chute.
hold small diameter branches together in a bundle and
feed in simultaneously.
Exclude pieces of metal, rocks, bottles, cans, and
3.
other foreign objects when feeding material into the
machine.
Feed brush from the side of the chipper chute, rather
4.
than from the front. Step aside to avoid being hit by
the brush moving into the chipper.
Place limb, butt end first, into the chipper chute until
5.
it contacts 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.
If the engine slows to where it may stall, stop feeding 6.
material and allow the engine to recover. Feed material
more evenly.
If the chipper jams, remove the branch and rotate it
7.
before reinserting it into the chute. Alternately insert
and retract the limb or insert continuously at a rate that
will not kill the engine.
do not use the clutch to clear a plugged rotor. this
8.
may cause belt damage. Refer to the instructions for
clearing a plugged rotor in the service and Maintenance
section.
Alternate greener material with dry material to
9.
lubricate the chipping blades for longer life and better
performance. Chipping dead, dry material will create
heat and dull the chipping blades quickly.
Sharpen the chipping blades periodically. Check the
10.
sharpness of the blades every 5-15 hours. Refer to
the Service and Maintenance section for sharpening
instructions.

harmful objects.
WaRNING
Never 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 feed brush. They can
cause extensive damage if they contact the blades.
In addition, metal pieces can be ejected from the
chipper chute and cause serious injury or death.
Never feed brush into the chute with your feet.
Never use hands or feet to clear materials that build up in
the chute.
