4 OPERATION
As with any other piece of outdoor equipment, getting the
feel for how your machine operates and getting to know
the best techniques for particular jobs are important to
overall good performance.
CHIPPING OPERATION
The chipping operation takes place in the middle of the
machine, where hardened steel chipper blades are
mounted on a rotating rotor assembly. Material fed into
the chipper chute is sliced into small chips and propelled
out through a discharge tube.
4.1 STARTING THE ENGINE
BEFORE ATTEMPTING TO START THIS MACHINE,
MAKE SURE THE BELT IS DISENGAGED AND THE
HANDLE IS IN THE “START” POSITION.
NEVER ATTEMPT TO START MACHINE WITH THE
DRIVE BELT ENGAGED.
1. Please refer to engine owner’s manual for priming
procedure for rst time starting, or if the unit has been
sitting for prolonged period.
2. Check levels of fuel, oil, and hydraulic uid and ll if
necessary.
3. Place chipper engagement handle in the START
position.
Before operating your machine, be sure you read
and understand all safety, controls and operating
instructions in this owner’s manual and on your
machine. Failure to follow these instructions can result
in serious injury or property damage.
WARNING
Move machine to a clear, level area outdoors before
starting. Do not operate in the vicinity of bystanders.
Make sure cutting chamber is empty before starting.
WARNING
4. Open the throttle slightly by turning throttle knob (A)
counterclockwise a 1/4 turn.
5. Turn key to the right or “On” position.
6. Press the start button on the engine controller. Engine
will begin autostart immediately and alarm will sound.
After 5-10 seconds of warming, the starter on the
engine will engage. The length of cranking will vary
depending on conditions. To interrupt the start-up
process, press the stop button.
4.2 OPERATING THE CHIPPER
To begin operating the chipper, follow the steps below:
1. AFTER engine is warmed for 2-3 minutes and is ready
for use, move the throttle control to approximately
25% of full throttle.
2. Engage the belt by slowly lowering the belt
engagement handle.
DO NOT engage the belt with engine running at
high RPM.
Engaging belt while engine is running at high
RPM will result in signicant belt squealing and
damage.
Engaging belt while engine is running at high
RPM can also damage vital drive components of
the chipper.
3. If the chipper engine stalls while engaging the
belt, move engagement handle back to the START
position, restart engine, SLIGHTLY increase throttle
and attempt engagement again.
4. Once the belt is engaged, continue to SLOWLY turn
the throttle knob counterclockwise to increase throttle
to 100% or full throttle. ALWAYS run the chipper at
100% or full throttle when chipping material.

16 9 INCH CHIPPER
OPERATION
5. If the chipper jams, the feed roller will reverse
momentarily to remove the branch. Once the branch
is removed, rotate it before reinserting into the
chute. Alternately insert and retract the limb or insert
continuously at a rate that will not kill the engine.
6. 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.
7. Limbs fed in to the chipper chute must be 9"
(22.9 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.
8. Alternate green or fresh cut 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 quicker.
9. ALWAYS 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.
10. ALWAYS place limb, butt end rst, 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.
11. NEVER use the belt engagement 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.
12. NEVER attempt to clear a plugged rotor or discharge
with the engine running. ALWAYS shut engine OFF
before servicing any part of this machine.
13. NEVER attempt to chip pieces of metal, rock, bottles,
cans or other foreign objects.
●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
Turn Throttle Lock Clockwise to Lock Throttle at 100%.
5. Turn Throttle Lock (A) clockwise to prevent losing
RPM while operating the machine.
4.3 CHIPPER OPERATION GUIDELINES
The machine chips a variety of materials into a more
readily decomposed or handled condition. The following
guidelines will help you get started.
1. Gradually increase engine speed until full throttle
is achieved. When the controller light is steady green
the engine speed is high enough to begin to chip.
2. ALWAYS run engine at full operating speed before
starting to chip material.
3. Engage the hydraulic feed by pushing the forward
button from the Chipping Screen (see Section 4.7 for
more details on utilizing the Digital Display Controller).
4. If the chipper rotor slows, the feed roller will stop
automatically to process backed up material. Feed
material more evenly.
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!
WARNING
●Obtain and wear safety glasses at all times when
operating the machine.
● Do not wear loose tting 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.
