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 on the front of the
machine, where hardened steel chipper blades are
mounted on a rotating disk assembly. Material fed into the
chipper chute is sliced into small chips and propelled out
through a discharge tube.
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
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.
3. Drive the skid steer forward until the top edge of the
coupler is completely under the top flange on the
chipper.
4. Tilt the unit backward until the chipper is slightly off
the ground.
5. Kill the engine and exit the machine to push down the
wedges using the universal skid steer mount levers
(Figures 4.1 and 4.2). On automated models, stay in
the machine and engage the wedges.
WARNING
The wedges must extend through the holes in the
mounting frame of the chipper to securely fasten the
chipper to the universal skid steer mount. Failure to
secure wedges can allow attachment to come off and
cause injury or death.

OPERATION
4.3 INSTALL FLUSH FACE COUPLERS
WARNING
Hydraulic lines may be under pressure due to testing
done at the factory.
The skid steer chipper is equipped to attach to ush face
couplers (Figure 4.3). The chipper is shipped with -12
sized hydraulic couplers tted on the hoses. A tie wrap is
used to indicate the pressure line. Be sure to connect the
hydraulic hoses to the proper ports.
If the skid steer is tted with anything other than -12 sized
ush face couplers on the main lines, it will be necessary
to replace the couplers supplied with the chipper.
The chippers are also equipped with a case drain hose.
The case drain is used to eliminate pressure on the
chipper’s hydraulic motor. The motor is rated for 250 to
300 psi of back pressure.
Most high ow skid steer loaders are equipped with a case
drain line. Standard ow skid steer loaders typically are not.
If the back pressure is over 300 psi, a case drain line
will have to be added. Contact your skid steer dealer for
details.
Figure 4.3 - Installed Couplers
4.4 PRE-OPERATION
IMPORTANT
NOT ADDING A CASE DRAIN LINE VOIDS THE
CHIPPER WARRANTY!
TO CONNECT:
1. Before connecting, make sure to relieve the hydraulic
pressure in the skid steer using the skid steer system.
2. Remove dirt and debris from the surface of the couplers.
3. Visually check the couplers for damage; replace if
damage is found.
4. Install the male coupler into the female coupler. Full
connection is made when the ball release sleeve slides
forward on the female coupler.
5. Turn the sleeve so that it is rotated away from the
locking pin to prevent accidental disconnection.
6. Repeat the procedure for all hoses, including the
smaller case drain hose.
TO DISCONNECT:
1. Relieve the hydraulic pressure in the skid steer using
the skid steer system.
WARNING
Do not attempt to bypass the safety systems of the
skid steer loader.
1. Wear appropriate eye, face, and hearing protection.
Wear gloves that fit tight against the wrist.
2. Remove the latch from the side of the feed table.
3. Lower the chipper feed table.
4. Check that the feed roller is clear of material.
5. Place the feed roller control in the “stop” position.
6. Push down the latch and rotate the discharge chute to
the desired position.
7. Release the handle and move the chute until it locks
the chute in position.
2. Rotate the ball sleeve so the grooves are aligned with
the pins in the female coupler.
3. Retract the sleeve on the female coupler until the
couplers disconnect.
4. Repeat the procedure for all hoses.

OPERATION
4.5 STARTING THE CHIPPER
Running the skid steer chipper is a one- or two-man
operation. If the system mandates an operator in the
driveseat, two people are needed. The chipper engages
with the hydraulics of the skid steer, as do most skid steer
powered attachments.
1. Set parking brake.
2. Ensure the feed roller is in the neutral position.
3. Engage the hydraulics of the skid steer to supply power
to the unit. The chipper will start to spin.
4. Place the feed roller in the operating position and bring
the unit up to speed.
5. The chipper is ready to chip.
4.6 STOPPING THE CHIPPER
1. Disengage the feed roller after all material has been
cleared from the chipper.
2. Slow down the engine of the skid steer to idle and after
several seconds disengage the skid steer hydraulics.
4.7 OPERATING THE CHIPPER
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.
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.
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!
WARNING
To prevent personal injury or property damage: shut
off engine and make sure that all moving parts have
come to a complete stop before, servicing, adjusting
or repairing. Disconnect the battery and remove
ignition key where applicable.
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 less
than 5 inches in diameter for model CH500H and
8 inches for model CH800H. The CH500H is most
effective when chipping 3-inch material. For material 4-5
inches, adjust the feed rate if the chipper starts to bog
down. The CH800H is most effective when chipping
5-inch material. When feeding materials that are 6-8
inches in diameter, adjust the feed rate if the chipper
starts to bog down.
3. 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.
4. Exclude pieces of metal, rocks, bottles, cans, and
other foreign objects when feeding material into the
machine.
5. 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.
6. 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.
7. If the engine slows to where it may stall, stop feeding
material and allow the engine to recover. Feed material
more evenly.
8. 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.
9. Do not use the hydraulic system to clear a plugged
rotor. Raise the feed roller with the jack. Refer to
Section 5.7.
10. 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.
11. 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.

5.4 SHARPENING THE BLADES5.3 CHIPPER BLADE MAINTENANCE
The chipper blades will eventually become dull, making
chipping difcult and adding extra strain on the machine.
CHECK THE SHARPNESS OF THE BLADES EVERY
5 - 15 HOURS OF OPERATION AND SHARPEN AS
NEEDED.
Your blades need to be sharpened if:
• Machine vibrates severely when material is fed into the
chipper.
• Small diameter branches do not self-feed.
• Chips discharge unevenly or have stringy tails,
especially when chipping green branches.
Before you sharpen the chipping blades, check for
permanent damage. Replace the blade if:
• There are cracks, broken corners or nicks greater than
1/8" (see below).
CRACK
GREATER
THAN 1/8”
BROKEN
CORNER
NICK GREATER
THAN 1/8”
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 5.1). Make sure some type of fixture 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.
5. Remove an equal amount off each blade to maintain
rotor balance.
6. Small imperfections such as nicks and burrs on the flat
side of the blade will not affect the chipping performance
of the machine.
7. For blades that have been repeatedly sharpened,
ensure that the sharpened surface extends past the
chipping slot opening. If it does not extend past the
opening, the blades should be replaced.
• The base of the cutting edge is worn or has been resharpened so that it no longer extends past the chipping
slot (see below).

SERVICE & MAINTENANCE
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE,
DISENGAGE THE HYDRAULICS AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
WARNING
5.5 INSTALLING THE BLADES
1. Remove any accumulated material from the blade
pocket and the bottom of the chipper blade.
2. Reinstall the chipper blades and tighten the bolts
to a torque of 25 Ft-lbs. (CH500H) or 120 Ft-lbs.
(CH800H).
3. Check the blade/anvil clearance and adjust if necessary.
4. Close the chipper housing and secure with removed
bolts to a torque of 25-28 Ft-lbs.
5. Reconnect machine hydraulics.
5.6 SETTING BLADE CLEARANCE
The chipping blades should clear the anvil by 1/16 to 1/8
inch. To adjust the blade clearance, proceed as follows:
1. Loosen the two (CH500H) or three (CH800H) anvil
bolts located underneath the feed roller housing (see
Figure 5.2).
2. Open the chipper blade access cover to view the gap
between the blades and anvil
3. On the CH500H, move the anvil assembly in or out by
turning the nuts on the block adjuster weldment.On the
CH800H, with the three anvil bolts loosened, adjust the
anvil to the desired position.
4. It is important to ensure that the minimum gap between
the chipping anvil and ALL chipping blades is 1/16". All
chipping blades should be rotated until even with the
chipping anvil and then measured. Failure to do so
can result in the chipping blades striking the chipping
anvil causing serious injury or death.
5. If the anvil cannot be moved to specifications due to
wear, rotate the anvil or replace the anvil.
6. Secure all hardware and adjust to torque.
5.7 RAISING THE FEED ROLLER
The feed roller lift jack is used to raise the feed roller to service
the machine or to clear material that has gotten wedged in
or behind the feed roller. To raise the feed roller:
1. Stop skid steer engine, disengage hydraulics, and allow
the machine to come to a complete stop.
2. Position the chipper chute to the side of the chipper.
3. Remove the two bolts on the chipper blade access
cover.
4. Tip the cover away from the chipper to expose the rotor
and the blades.
5. Turn the check valve located on the bottom of the jack
clockwise, engaging the jack.
6. Remove the lock pin from its storage position (see
figure below).
7. Pump the handle to raise the feed roller until the lock pin
position aligns with one of the support bracket holes.
8. Secure the position by putting the lock pin through the
support bracket and lock pin position. This will ensure
the feed roller cannot fall from the upright position.
9. Service the machine.
10. To lower the feed roller support, remove the lock
pin and then turn check valve counterclockwise to
disengage the pump.
11. Replace lock pin in storage position.
12. Lower access cover and reattach the two bolts.
