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.
SHREDDING OPERATION
In this operation, hardened steel shredder knives grind
up material fed into the shredder chute. The shredded
material then leaves the shredder area by traveling
through the discharge screen. The shredded material can
be diverted into a container or onto the ground.
4.1 STARTING THE CHIPPER
1. Connect PTO driveline to tractor as described in
Section 2.4.
2. Adjust 3‑point top link so the chipper sits level.
3. Start tractor engine and engage PTO (refer to tractor
owner’s manual). Increase engine speed to rated
PTO RPM.
4.2 STOPPING THE CHIPPER
1. Move tractor throttle to slowest position.
2. Disengage PTO lever and shut o󰀨 tractor engine.
3. Allow machine to come to a complete stop.
Do not inspect or work on PTO drive area without rst
disengaging PTO and shutting o󰀨 tractor engine.
WARNING
If forward and reverse feed positions are reversed
when you power up the machine, you may have
plugged the connectors into the wrong plug.
NOTE
The rotor will continue to turn for some time after the
engine has been shut o󰀨. Make sure rotor has stopped
completely before inspecting or servicing machine.
NOTE

ENGLISH
OPERATION
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. Gradually increase engine speed to rated PTO
RPM.
2. ALWAYS run engine at rated PTO RPM before
starting to chip material.
3. If the chipper rotor slows, stop feeding material.
Allow the rotor to process backed up material. Feed
material more evenly.
4. If the chipper jams, remove the branch and 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.
5. 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.
6. Limbs fed in to the chipper chute must be 5"
(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.
7. Material fed into the shredder chute must be 3/4"
(1.9 cm) in diameter or less. Common shredding
materials include grass, leaves, garden refuse, sticks,
and small branches.
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 and remove the PTO shaft from tractor 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
●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
DO NOT INSERT BRANCHES LARGER THAN 3/4"
(1.9 cm) INTO SHREDDER OR MACHINE DAMAGE
MAY OCCUR.
WARNING

As the Limited Warranty states, failure by the Owner to perform normal maintenance will void the machine’s
warranty. The aggressive, high-speed nature of chipping REQUIRES THE OWNER TO PERFORM THE
ABOVE LISTED NORMAL MAINTENANCE. Special consideration to maintain and re-torque the CHIPPER
ANVIL, CHIPPER BLADES, and ALL INTERNAL AND EXTERNAL NUTS AND BOLTS is the sole responsibility
of the Owner. Failure by the Owner to do so shall be cause for denial of warranty.

ENGLISH
SERVICE & MAINTENANCE
WARNING
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE,
AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
The chipper blades will eventually become dull, making
chipping di󰀩cult 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.
●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).
●The base of the cutting edge is worn or has been
re-sharpened so that it no longer extends past the
chipping slot (see below).
5.2 CHIPPER BLADES MAINTENANCE
1. Remove the discharge door by removing the retaining
bolt securing the discharge door/to the chipper body.
2. Remove the two 5/16" × 3/4" bolts and nuts securing
the discharge screen to the frame. Pull the bottom of
the discharge screen outward to rotate the screen o󰀨
the lip.
3. Remove the access cover on the side of the machine.
4. Rotate the rotor so the bolts holding the chipper blade
are accessible.
5. Remove the two bolts holding the blade to the rotor.
Repeat for remaining blades.
Chipping blades are sharp! Use caution when working
on machine to avoid injury.
WARNING
5.3 REMOVING THE BLADES
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 chopping blades to
45 degrees (Figure 5.1). Use the blade angle gauge
plate when sharpening the blades to achieve the
proper angle (see Figure 5.2).
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. Place a blade on the rotor and attach with two 5/16 ×
1" bolts. Torque to 25 ft‑lbs. Repeat for the remaining
blades.
2. Reinstall the discharge screen by placing the top lip
of the screen into the slot under the top slope of the
chipper body and rotating the screen so that the bolt
holes align with the holes in the chipper body.
3. Secure using two 5/16" × 3/4" bolts and nuts; torque
to 17 ft-lbs.
4. Reinstall the discharge door.
5.5 INSTALLING THE BLADES
Figure 5.3, Examples of Damage to Knives
Do not attempt to sharpen shredder knives. Inspect the
knives often for signs of damage.
If a knife has any sign of cracking or is broken in any way,
it should be replaced immediately.
5.6 SHREDDER KNIVES MAINTENANCE
5. Remove an equal amount o󰀨 each blade to maintain
rotor balance.
6. Small imperfections such as nicks and burrs on
the at side of the blade will not a󰀨ect 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 (see
Section 5.3).
1. Remove the discharge door and discharge screen.
2. Remove the rear side access cover.
3. Work with one knife shaft at a time. Remove the
#10-24 bolt and nut from the knife shaft and discharge.
Do not reuse.
4. Using a hammer and punch, drive the knife shaft
through the access hole on the rear of the machine.
5. Remove the spacers and shredder knives. Be careful
to keep track of the order the spacers were installed
on the shafts so they can be returned to the original
locations. If the spacers and knives are not installed
correctly, the rotor will be out of balance and will not
have proper shredding action.
6. Reverse or replace the knives and reassemble onto
the rotor. Install a new #10-24 bolt and nut through
the spacer and shaft. Torque to 36 in-lbs.
7. Repeat for remaining shafts.
8. Replace the rear access cover, discharge screen and
discharge door. Torque all 5/16" bolts to 17 ft‑lbs.
5.7 REMOVING THE SHREDDER KNIVES
The serrated edge of the shredder knives should face
the same direction as the cutting edge of the chipper
blades. Never reuse the #10-24 nut and bolt. Never
reuse shafts or spacers if they show signs of wear or
abuse. Always install new parts when repairing.

5.12 REMOVING THE ROTOR
The rotor weighs in excess of 100 lbs. It is extremely
important to support the rotor to prevent it from falling
or shifting as the shaft is removed.
WARNING
5.13 PTO DRIVELINE LUBRICATION
1. Every 8 hours, lubricate PTO cross journals. Make
sure grease purges through all four bearings.
2. Every 8 hours, lubricate PTO inner tubes. Telescoping
members must have lubrication to operate
successfully. Telescoping members without ttings
should be pulled apart and grease should be added
manually with a brush.
3. Every 8 hours, lubricate the PTO shield retaining
bearing. Molded nipples on the guard near each
guard bearing are intended as grease ttings and
should be lubricated every 8 hours of operation.
To prevent personal injury or property damage:
Disconnect the PTO driveline from the source providing
power or disconnect the driveline from the chipper
