alcohol or drugs.
8. Always wear eye and hearing protection when operating
this unit.
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 firm,
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.
14. Never leave the machine running unattended. Always turn
off 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 fingers 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 sufficient 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 fire, or
overheating of the engine.
20. Never attempt to reposition or move the chipper/shredder

making unusual noise or vibration. Shut the engine off
immediately, allow the rotor to stop, disconnect the
spark plug wire and secure the wire away from the spark
plug. Inspect the unit for any signs of damage or foreign
material in the chipping or shredding areas. Remove
any solid material that may be preventing the unit from
operating properly.
22. Never attempt to clear clogs from the chipper cone,
shredder hopper or discharge chute while the unit is
running. Always shut the engine off, allow the rotor to
come to a complete stop, and remove the spark plug wire
from the spark plug before removing excess materials.

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 flame 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 off if children enter the area.
3. Never allow children to operate the unit.

Engine Stop / Throttle Control
The engine stop / throttle control lever controls turn the
engine off 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. Always operate at FULL throttle (lever fully right).
Recoil Starter
The recoil starter is used to turn the engine over for starting.
Fuel Shut-Off Valve
The fuel shut-off valve is located below the air cleaner
housing. Always close the valve when the unit is not in use.
Choke
Close the choke for cold starting. Open the choke once the
engine starts. A warm engine may not require choking. Move
the lever right to close the choke.
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 .

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
firmly in place.
4. Pull the starting rope out to begin turning the engine over.
Pull slowly at first 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
running it for at least a minute.
6. Set throttle to FULL and begin chipping/shredding.
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
first into the chipper cone. Since occasional kick-backs may
occur, always stand off 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 flow.
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
