The Owner/Operator’s manual uses this symbol to alert
you of potential hazards. Whenever you see this symbol,
read and obey the safety message that follows it. Failure
to obey the safety message could result in personal injury,
death or property damage.
DANGER
Indicates an imminently hazardous situation that, if not
avoided, will result in death or serious injury.
The engine on your power equipment, like most outdoor
power equipment, is an internal combustion engine that
burns gasoline or diesel fuel (hydrocarbons). Therefore,
your power equipment must be equipped with a spark
arrester mufer in continuous effective working order. The
spark arrester must be attached to the engine exhaust
system in such a manner that ames or heat from the
system will not ignite ammable material.
Failure of the owner/operator of the equipment to comply
with this regulation is a misdemeanor under California law
and may also be a violation of other state and/or federal
regulations, laws, ordinances, or codes. Contact your
local re marshal or forest service for specic information
about which regulations apply in your area.
The standard mufer installed on the engine is not
equipped with a spark arrester. One must be added
before using this machine in an area where a spark
arrester is required by law. Contact the local authorities
if these laws apply to you. See your authorized engine
dealer for spark arrester options.

OPERATION
4.3 OPERATING THE CHIPPER/SHREDDER
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!
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
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.
The machine chips and shreds a variety of materials into
a more readily decomposed or handled condition. The
following guidelines will help you get started.
Run unit at full operating speed1. before starting to
chip material.
Limbs fed in to the chipper chute must be 2.75 2.
inches (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.
Material fed into the shredder chute must be ¾ 3.
inches (2 cm) in diameter or less. Common shredding
materials include grass, leaves, garden refuse, sticks,
and small branches.
Exclude pieces of metal, rocks, bottles, cans, and 4.
other foreign objects when feeding material into the
machine.
Feed brush from the side of the chipper chute, 5. rather
than from the front. Step aside to avoid being hit by the
brush moving into the chipper.
Place limb, butt end first, into the chipper chute 6. 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.
If the engine slows to where it may stall, 7. stop feeding
material and allow the engine to recover. Feed material
more evenly.
If the chipper jams,8. 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.
Do not use the clutch to clear a plugged rotor. 9. This
may cause belt damage. Refer to the instructions for
clearing a plugged rotor in the Service and Maintenance
section.
Alternate greener material with dry material10. to
lubricate the chipping blades for longer life and better
performance. Chipping dead, dry material will create
heat and dull the chipping blades quickly.
Sharpen the chipping blades periodically.11. Check
the sharpness of the blades every 5-15 hours. Refer
to the Service and Maintenance section for sharpening
instructions.

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.
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).
Inspect blade to see if cracks or nicks are visible. If 3.
cracks are present, the blade cannot be resharpened
and must be discarded (see Sec. 5.2).
If the other side of the blade has not been used yet, 4.
the blade can be rotated so that the new edge is in
position and reused.
If both sides of the blade have been used, it must be 5.
resharpened. The blades can be ground on a bench
grinder (see Sec 5.4) or by a professional.
Replace blade on the rotor. Note correct orientation 6.
of cutting edge to rotor (see Sec. 7.1).
Secure with two 5/16" x 1/2" bolts and torque to 25 ft-lb. 7.
Repeat steps 2-7 for the second blade.8.
5.4 SHARPENING 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.
ENGLISH
5.3 REMOVING THE CHIPPER BLADES
Remove the eight 1.
5/16" nuts holding
th e e n g i n e a n d
plate to the frame
(see Fig. 5.1) and
remove the engine
a n d p lat e f r o m
frame.
To remove a blade, 2.
remove the two 5/8"
bolts securing the
blade to the rotor.
Note the relation of
blade cutting edge
to rotor.
Fig. 5.1 Remove these bolts and four
on other side
2. Regrind the angled edge of the chipping blades to 45
degrees (Figure 5.2). 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

5.5 REPLACING SHREDDER KNIVES
CAUTION
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.
The serrated shredder knives are designed to offer long
life and can be reversed if they become dull. For a
replacement kit, refer to the Parts Section.
To reverse the knives or install a new shredder knife kit,
proceed as follows:
Remove the eight 5/16" nuts holding the engine and 1.
plate to the frame (see Figure 5.1).
Remove engine, plate and rotor assembly from frame.2.
Working one shaft at a time, remove the 10-24 x 1-1/8" 3.
screw and 10-24 nylock nut from the knife spacer
located on the shaft.
Push the shaft out of the rotor assembly and remove 4.
the knife spacers. Keep track of the order the spacers
are installed on the shafts so they are returned to the
original location (see Figure 5.3). If the spacers and knife
sections are not installed properly, the rotor will be out of
balance and will not have proper shredding action.
Reverse and reinstall the existing knives and spacers 5.
or install new knife sections and spacers onto the shaft.
Secure the shaft with a new 10-24 x 1-1/8" screw and
10-24 nylock nut. Torque to 36 in-lb.
Repeat for the remaining shaft.6.
Replace engine, plate and rotor assembly and secure 7.
with eight 5/16" nuts.
Remove 2. left nut and bolt holding the discharge screen
in place (see Fig. 5.4).
Reach up into the discharge chute and pivot that side 3.
of the discharge screen down.
Clean any trash or debris from the screen area, being 4.
careful not to touch the sharp blades.
Pivot the screen back up to its original position.5.
Secure with the 5/16" nut and 5-1/2" bolt.6.
5.7 CHANGING THE DISCHARGE SCREEN
There is one optional discharge screen available with a
smaller mesh that will produce smaller-sized shredded
product. Refer to the Parts Section for this screen. To
change the discharge screen, proceed as follows:
Remove the two 5/16" nuts and 5-1/2" bolts securing 1.
the discharge screen and pull the discharge screen
out from the bottom.
Clean any trash or debris from the screen area.2.
Insert the replacement screen into the bottom of the 3.
chipper body.
Secure with two 5/16" x 5-1/2" bolts and 5/16" nuts.4.

5.6 CLEARING A PLUGGED ROTOR
If too much material is fed into the chipper/shredder or
if the material is too large, the machine may become
plugged. To clear a plugged rotor, proceed as follows:
Turn off the machine and let all moving parts come to 1.
a complete stop.
