2. Do not put hands or feet near rotating parts or under
the machine. Keep clear of the discharge opening at all
times.
3. Only allow responsible adults, who are familiar with the
instructions, to operate the unit (local regulations can
restrict operator age).
4. Be sure the area is clear of other people before operating.
Stop the unit if anyone enters the area.
5. Never direct discharge material toward anyone. Avoid
discharging material against a wall or obstruction.
Material may ricochet back toward the operator.
6. Operate the machine only in daylight or good articial
light.
7. Do not operate the unit while under the inuence of
alcohol or drugs.
8. Always wear eye and hearing protection when operating

9. Keep in mind the operator is responsible for accidents
occurring to other people or property.
10. It is a violation of California Public Resource Code Section
4442 to use or operate the engine on or near any forest-
covered, brush-covered, or grass-covered land unless the
exhaust system is equipped with a spark arrester meeting
any applicable local or state laws. Other states or federal
areas may have similar laws.
11. Always operate the chipper shredder outdoors, on a rm,
level, earthen or grassy surface where the unit will be
stable and stay in position. Never attempt to operate the
unit on a slope, or on a wet or slippery surface where you
could slip and fall toward the chipper cone or hopper
openings.
12. Never operate the chipper shredder on asphalt, concrete,
or other hard surfaces as material being ejected out of
the discharge chute could ricochet, causing injury to you
or bystanders.
13. Always obey the size limitations for tree limbs and
branches stated in the Waste Materials Guide portion of
this manual.
IMPORTANT
THE RIGHT AND LEFT SIDES OF YOUR CHIPPER
SHREDDER ARE DETERMINED FROM THE OPERATING
POSITION, STANDING AND FACING THE UNIT.
ENGINE IS SHIPPED FROM FACTORY WITHOUT OIL.
YOU MUST ADD ENGINE OIL BEFORE STARTING
ENGINE.
14. Never leave the machine running unattended. Always
turn o the engine, wait for the rotor to come to a
complete stop, and disconnect the spark plug before
leaving the area. Always move the unit to a safe storage
area when not in use.
15. Always maintain secure footing and solid balance while
starting or operating the chipper shredder. Never lean
directly over the machine.
16. Always stand to the side of the chipper cone when
feeding tree limbs and branches into the unit, as tree
limbs, branches, and harder woods may kick back while
being chipped.
17. Always keep hands out of the chipper cone and shredder
hopper when feeding materials. Never wrap ngers
tightly around branches as you are feeding them into the
unit, as a sudden inward surge could pull your hands and
arms into the unit.
18. Never allow material to build up in the discharge area
or shredding chamber, as this may cause new material
being fed into the machine to kickback with sucient
force to injure you or other bystanders.
19. Never allow material to build up around the engine
during chipper shredder operation. This could result in a
re, or overheating of the engine.
20. Never attempt to reposition or move the chipper
shredder unit while it is running. Doing so could cause
the machine to tip over, and reaching to steady the unit
could result in accidental insertion of your hands into the

when refueling the unit after transportation or storage.
2. Never store the unit (with fuel) in an enclosed poorly
ventilated structure. Fuel vapors can travel to an ignition
source (such as a furnace, water heater, etc.) and cause
an explosion. Fuel vapor is also toxic to humans and
animals.
3. Always use the hopper handle and built-in wheels to
move the chipper shredder. Never lift the unit using the
fuel tank for support. If the unit must be lifted , always
use at least two people, and always grip the unit securely
using the front leg and hopper handle.
4. Always follow the engine manual instructions for storage
preparations before storing the unit for both short and
long term periods.
5. Always follow the engine manual instructions for proper
start-up procedures when returning the unit to service.
6. Never store the unit or fuel container inside where there
is an open ame or pilot light, such as in a water heater.
Allow unit to cool before storing.
Children
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the unit
and the operating activity. Never assume that children will
remain where you last saw them.
1. Keep children out of the work area and under the
watchful care of another responsible adult.
2. Be alert and turn unit o if children enter the area.
3. Never allow children to operate the unit.
Emissions
1. Engine exhaust from this product contains chemicals
known, in certain quantities, to cause cancer, birth
defects, or other reproductive harm.
2. Look for the relevant Emissions Durability Period and Air
Index information on the engine emissions label.
Ignition System
1. This spark ignition system complies with Canadian ICES-
002.
SERVICE AND MAINTENANCE
Safe Handling of Gasoline
1. Extinguish all cigarettes, cigars, pipes, and other sources
of ignition.
2. Use only approved gasoline containers.
3. Never remove the gas cap or add fuel with the engine
running. Allow the engine to cool before refueling.
4. Never fuel the machine indoors.
5. Never store the machine or fuel container where there is
an open ame, spark, or pilot light such as near a water
heater or other appliance.
6. Never ll containers inside a vehicle or on a truck bed
with a plastic bed liner. Always place containers on the
ground away from your vehicle before lling.
7. Remove gas-powered equipment from the truck or

Control Functions
The information below briey describes the function of individual controls. Operating requires the combined use of several controls
applied in specic sequences. To learn what combination and sequence of controls to use for various tasks see the OPERATION section.
FEATURES & CONTROLS
Fuel Tank
To remove the cap, turn counterclockwise.
Chipper Cone / Shredder Hopper
Chipper Cone: The chipper cone is
located on the front of the unit next to
the engine. Insert branches and tree
limbs up to approximately 3”(7.6 cm) in
diameter into the chipper cone. NEVER
insert hands past the mouth of the cone.
Shredder Hopper: The shredder hopper
is on top of the unit. Leaves and other
light waste can be loaded into the
shredder hopper. NEVER insert hands
into the hopper .
Debris Bag: Use the debris bag to collect
the material discharged from the unit. Do
not operate the unit without the debris
bag in place.
Engine Stop / Throttle Control
The engine stop / throttle control lever
controls turn the engine o and controls
the engine speed. Move the throttle
right to increase engine speed and left to
decrease engine speed. Moving the lever
all the way to the left stops the engine.

GENERAL OPERATING SAFETY
Be sure to read all information in the Safety and Operation
sections before attempting to operate this unit. Become
familiar with all of the controls and how to stop the unit.
Upon start-up and shut-down, you may hear the metal-
to-metal sound of the triangular hammers and J-hammers
positioning themselves on the rotor. This is normal. If this
sound continues after the machine has reached full speed,
contact your dealer for an inspection of the unit. Overloading
the equipment will shorten its life, and can cause mechanical
failures.
Chipper Operation
The chipper is designed to handle tree limbs and branches up
to approximately 3”(7,6 cm) in diameter. The chipping knives
also permit the processing of course organic matter like corn
stalks. Tree branches must be inserted large-end rst into the
chipper cone. Since occasional kick-backs may occur, always
stand o to the side of the unit. Allow the self-feeding action
of the unit to draw the sticks in.
Shredder Operation
The shredder is designed to shred light brush, leaves, and
other soft but bulky organic waste. As material is loaded into
the shredder hopper it is pulled into the path of the triangular
and J-hammers by air ow.
Vacuum Attachment (Optional)
In addition to the chipper cone and hopper, loose debris may
be processed by the Vacuum hose adapter kit. Leaves may be
raked directly into the leaf tray where vacuum action will draw
them into the shredder. For hard-to-reach areas, the nozzle
and hose assembly may be used. The strength of the Vacuum
may be changed using the rotating sleeve on the nozzle. (See
Vacuum Kit parts explosion on page 28.)
Operating Location
Select an area with rm, level ground, covered by dirt or grass.
Do not operate on wet or slick surfaces, or near bystanders.
Locate and organize the materials to be processed so that you
don’t have to walk in front of the inlet or discharge openings,
and so you have adequate room to work safely.
Adding Fuel
To add fuel:
1. Remove the fuel cap (see Figure 1).
2. Fill the tank. Do not overll. Leave room in the tank for
fuel expansion. Refer to your engine manual for specic
fuel recommendations.
3. Install and hand tighten the fuel cap.
DANGER
THE EXHAUST FROM THIS PRODUCT CONTAINS
CARBON MONOXIDE GAS. CARBON MONOXIDE IS A
COLORLESS, ORDERLESS AND TASTELESS GAS THAT
CAN CAUSE DIZZINESS, NAUSEA, UNCONSCIOUSNESS
OR EVEN BRAIN DAMAGE AND DEATH IF INHALED FOR
PROLONGED PERIODS.
OPERATE THE UNIT OUTDOORS IN A WELL
VENTILATED LOCATION ONLY. KEEP CHILDREN, PETS
AND BYSTANDERS AWAY.
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY
RESULT IN SERIOUS INJURY OR DEATH
WARNING
GASOLINE IS HIGHLY FLAMMABLE AND MUST BE
HANDLED WITH CARE. NEVER FILL THE TANK WHEN
THE ENGINE IS STILL HOT FROM RECENT OPERATION.
DO NOT ALLOW OPEN FLAME, SMOKING OR MATCHES
IN THE AREA. AVOID OVERFILLING ANDWIPE UP ANY
SPILLS.
WARNING
TO AVOID SERIOUS PERSONAL INJURY FROM
ROTATING CUTTING BLADES, KEEP HANDS OUT OF
INLET WHILE MACHINE IS RUNNING.
WARNING
DO NOT USE GASOLINE CONTAINING METHANOL,
GASOHOL CONTAINING MORE THAN 10% ETHANOL,
GASOLINE ADDITIVES OR WHITE GAS BECAUSE
ENGINE/FUEL SYSTEM DAMAGE COULD RESULT.
Starting the Engine
1. Set the throttle to FULL.
2. Close the choke.
NOTE: A warm engine may not require choking.
3. Place one foot on the front support leg to hold the unit
rmly in place.
4. Pull the starting rope out to begin turning the engine
over. Pull slowly at rst and increase speed with each
successive pull.
5. After the engine starts, open the choke and move the
engine throttle control to SLOW. Warm up the engine by

Storage
Before you store your unit for the o-season, read the
Maintenance and Storage instructions in the Safety Rules
section, then perform the following steps:
• Perform engine maintenance and storage measures
listed in the engine owner’s manual. This includes
draining the fuel system, or adding stabilizer to
the fuel (do not store a fueled unit in an enclosed
structure - see warning).
Before starting the unit after it has been stored:
• Check all uid levels. Check all maintenance items.
• Perform all recommended checks and procedures
found in the engine owner’s manual.
• Allow the engine to warm up for several minutes
before use.
Stopping the Engine
NOTE: In the event of an emergency the engine can be
stopped by setting the throttle control to STOP.
1. Slide the throttle control fully left to the STOP position.
NOTE: Upon start-up and shut-down, you may hear the
metal-to-metal sound of the triangular hammers
and J-hammers positioning themselves on the
rotor. This is normal.
2. After the engine has stopped moving, remove the spark
plug wire and remove any debris from the unit and
engine.
Processing Materials
Most materials to be processed can be handled more
eciently by following these tips.
Chipping Tips:
• Prune branches down close to the main branch to
make feeding them into the chipper cone easier.
• Large, hard, dried tree branches that resist chipping
can be processed by rotating them as you alternately
insert and retract them.
• If the material to be chipped is extremely hard, kicks
back forcefully when being fed into the chipper cone,
or cannot be easily controlled, remove the material
immediately and set it aside.
• If additional force is required to insert materials
into the chipper, the blades probably need to be
sharpened. Consult the Troubleshooting and Repair
section of this manual, or see your authorized dealer.
• Maintain control of the materials you are feeding to
prevent them from whipping around.
• Do not insert short pieces of material into the chipper
cone by hand. Use a larger piece of material to force
them into the chipper cone.
• Shredding Tips
• Don’t overload the shredder by dumping large
volumes of material into the hopper opening.
• Alternate loads of wet and dry material to prevent the
discharge from becoming plugged.
• Never use any object to force material into the
shredding chamber. It could get caught in the
shredding hammers and damage the unit.
