14 8 INCH TURNTABLE CHIPPER
OPERATION
4.6 RAISE/LOWER ACCESS COVER
1. Rotate the discharge chute so it is parallel to the access
cover.
2. Remove the two 3/8 x 1-1/4" bolts, nuts and washers
securing the access cover to the chipper housing.
3. After lowering the access cover, secure the access
cover to the chipper housing using two 3/8 x 1-14" bolts,
nuts and washers.

4.5 OPERATING THE CHIPPER
WARNING
WARNING
Read and follow all safety instructions in this manual.
Failure to operate the machine in accordance with
the safety instructions MAY RESULT IN PERSONAL
INJURY!
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.
CAUTION
Obtain and wear safety glasses at all times when
operating the machine.
Do not wear loose fitting clothing.
The operator should always wear heavy boots, gloves,
pants and a long-sleeved shirt.
Use common sense and practice safety to protect
yourself from branches, sharp objects, and other
harmful objects.
The machine chips a variety of materials into a more
readily decomposed or handled condition. The following
guidelines will help you get started.
1. With the engine slightly above idle, engage
the chipper blades by slowly pushing the chipper
engagement handle down.
2. Gradually increase engine speed with the throttle
until full idle is achieved. When the controller light
is steady green the engine speed is high enough to
begin to chip.
3. Engage the hydraulic feed by pushing the feed roller
control arm into forward position.
4. Limbs fed in to the chipper chute must be 8 inches
(20 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.
5. Place limb, butt end first, into the chipper chute until
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.
6. Do not feed pieces of metal, rocks, bottles, cans, or
other foreign objects into the machine.
7. Feed brush from the side of the chipper chute, rather
than from the front. Step aside to avoid being hit by the
brush moving into the chipper.
8. If the chipper disk slows, stop feeding material. The
feed roller will stop automatically to process backed up
material. Feed material more evenly.
9. If the chipper jams, the feed roller will reverse
momentarily to remove the branch.
10. Do not use the clutch to clear a plugged rotor. This
may cause belt damage. Refer to the instructions for
clearing a plugged rotor in the Service and Maintenance
section.
11. Alternate greener material with dry material to
lubricate the chipping blades for longer life and better
performance. Chipping dead, dry material will create
heat and dull the chipping blades quickly.
12. Sharpen the chipping blades periodically. Check
the sharpness of the blades every 5-15 hours. Refer
to the Service and Maintenance section for sharpening
instructions.
This machine is equipped with a flow control to vary the
speed of the feed roller. This allows the operator to in-
crease the feed speed when processing smaller material
and lower the speed when handling material close to the
maximum capacity of the machine. It is recommended
that operators start using the machine at the lower limits
of the speed control and slowly increase the speed, ac-
cording to the size and hardness of the material being
chipped.
While occasional stopping and starting of the feed roller
is normal, frequent stopping and starting of the feed roller
and/or rapid decreases in chipper rotor rpms is an indica-
tion that the feed speed is too high. Continued operation
under such conditions can result in plugging of the dis-
charge, belt damage, and inefficient operation.
