4 OPERATION
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
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
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 on the front 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 ENGINE
1. Before starting, check levels of engine oil and fuel.
2. Place the throttle control midway between slow and
fast positions.
3. Move the choke lever to the ON position. When
restarting a warm engine after a recent shut down, it
may not be necessary to use a full choke. If the engine
fails to start, move the lever to OPEN or partial choke.
4. Move lever to START position.
4.2 STOPPING ENGINE
1. Move throttle to slowest position.
2. Allow motor to idle for 1 minute.
3. Turn engine switch to OFF position.
4. Allow machine to come to a complete stop.
5. Turn the key to the START position. Release the key
as soon as the engine starts. Do not crank engine for
more than 10 seconds.
6. Move choke lever to OPEN position.
7. Once engine is running and no choke is needed,
slowly engage lever into the CHIPPING position. This
will engage the chipping disc.
8. If the engine kills when engaging the belt, either adjust
choke or increase engine RPM.
Do not crank the engine continuously for more than 10
seconds. If the engine does not start, allow a 60 second
cool down period between starting attempts. Failure to
follow these guidelines can damage the starter motor.
Do not jump start engine.
IMPORTANT
The heavy rotor will continue to turn for some time after
the engine or tractor has been shut o󰀨. You can tell
that the rotor has stopped when no noise or machine
vibration is present. Inserting a branch into the chipper
chute to contact the blades will slow the rotor and
shorten stopping time.
NOTE
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
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. Run unit at full operating speed before starting to
chip material.
2. Limbs fed in to the chipper chute must be 5 inches
(12.7 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.

115 INCH CHIPPER
ENGLISH
OPERATION
3. Exclude pieces of metal, rocks, bottles, cans, and
other foreign objects when feeding material into the
machine.
4. 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.
5. 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.
6. If the engine slows to where it may stall, stop
feeding material and allow the engine to recover.
Feed material more evenly.
●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 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.
CAUTION
4.4 TOWING
4.4.1 ATTACHING
1. Rotate the discharge tube to face the opposite
direction of the towing vehicle before towing.
2. Raise rear stabilizer.
3. Raise the extension tray to an upright position before
towing the machine. Secure with the spring-loaded
latch located near the top of the tray.
4. Open the coupler latch.
5. Raise the trailer hitch until the coupler is above the
height of the hitch ball on the towing vehicle.
6. Align the coupler over the hitch ball and lower the
trailer hitch until the coupler fully engages the hitch
ball.
7. Close the coupler latch securing the coupler to the
hitch ball.
8. Install the hitch pin through the coupler latch.
9. Cross the safety chains under the hitch and connect
to towing vehicle.
10. Connect the wire harness to the tow vehicle.
11. Raise the jack stand and rotate 90 degrees.
Optimum towing performance can be achieved by
maintaining a horizontal trailer hitch.
NOTE
7. If the chipper jams, remove the branch and rotate it
before reinserting it into the chute. Alternately insert
and retract the limb or insert continuously at a rate that
will not kill the engine.
8. Do not use the engagement lever 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.
9. 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.
10. 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.
4.4.2 DETACHING
1. Unhook the safety chains from the towing vehicle.
Latch safety chains to the hitch to prevent them from
interfering with chipping.
2. Disconnect the wire harness from tow vehicle.
3. Remove the hitch pin from the coupler latch.
4. Unlatch the coupler. Disconnect the hitch coupler from
the hitch ball. Rotate jack stand 90 degrees. Raise

The blades can be ground on a bench grinder or by a
professional.
1. Never sharpen or grind the mounting surfaces of
the blades. This will cause the edge to roll and the
blade will be damaged, resulting in poor chipping
performance.
2. Regrind the angled edge of the chipping blades to 45
degrees (Figure 5.2). Make sure some type of xture
is used to correctly hold the blade at the proper angle.
3. Be careful when grinding so that the blade does
not become overheated and change color. This will
remove the heat-treated properties.
4. Use short grinding times and cool with water or some
type of liquid coolant.
1. Install the rotor lock (Section 5.2). The rotor is now
restrained for installing the blades.
2. Place a blade on the rotor and attach using original
hardware. Torque the bolts to 25 ft-lbs (34 Nm).
Repeat for the remaining blade.
3. Lower the access cover and secure to the chipper
housing using two 3/8" retaining bolts.
