Operating Safety
Congratulations on purchasing a superior-quality piece of
lawn and garden equipment. Our products are designed and
manufactured to meet or exceed all industry standards for
safety.
Power equipment is only as safe as the operator. If it is
misused, or not properly maintained, it can be dangerous!
Remember, you are responsible for your safety and that of
those around you.
Use common sense, and think through what you are doing. If
you are not sure that the task you are about to perform can
be safely done with the equipment you have chosen, ask a
professional: contact your local authorized dealer.
Read the Manual
The operator’s manual contains important safety information you need to be aware
of BEFORE you operate your unit as well as DURING operation.
Safe operating techniques, an explanation of the product’s features and
controls, and maintenance information is included to help you get the most
out of your equipment investment.
Be sure to completely read the Safety Rules and Information found on the
following pages. Also completely read the Operation section.
Children
Tragic accidents can occur with children. Do not allow them
anywhere near the area of operation. Children are often
attracted to the unit and usage activity. Never assume
that children will remain where you last saw them. If there
is a risk that children may enter the area where you are
operating, have another responsible adult watch them.

Safety Rules and Information
Moving Parts
This equipment has many moving parts that can injure you or
someone else. However, if you follow all the rules in this book, the
unit is safe to operate.
The chipper/shredder has spinning blades that can amputate
hands and feet. Do not allow anyone near the equipment while it is
running! Do not place hands or feet in the hopper or chipper cone,
or discharge chute.
Thrown Objects
This unit discharges debris at high speeds. Always wear protective goggles and
do not operate without the debris bag in place. Also, do not allow anyone in the
area while the unit is running! If someone does enter the area, shut the unit off
immediately until they leave. Organize the work area prior to starting work.
Fuel and Maintenance
Gasoline is extremely flammable. Its vapors are also extremely flammable and
can travel to distant ignition sources. Gasoline must only be used as a fuel, not
as a solvent or cleaner. It should never be stored any place where its vapors
can build up or travel to an ignition source like a pilot light. Fuel belongs in an
approved, plastic, sealed gas can, or in the fuel tank with the cap securely closed.
Spilled fuel needs to be cleaned up immediately.
Proper maintenance is critical to the safety and performance of your unit. Be
sure to perform the maintenance procedures listed in this manual, especially
periodically testing the safety system.

Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of unit,
severe personal injury or death to you, or bystanders, or damage to property or equipment.
This unit is capable of amputating hands and feet and throwing objects. The triangle in text signifies
important cautions or warnings which must be followed.
PREPARATION
1. Do not operate the equipment without wearing
adequate outer garments and safety goggles. Avoid
loose-fitting clothes and use protective footwear that will
improve footing on slippery surfaces.
TRAINING
1. Read the operating and service instructions carefully.
Be thoroughly familiar with the controls and the proper
use of the equipment. Know how to stop the unit and
disengage the control quickly.
2. Keep the area of operation clear of all persons,
particularly small children, and pets.
GENERAL OPERATION
1. Read, understand, and follow all instructions in the
manual and on the unit before starting.
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 artificial
light.
7. Do not operate the unit while under the influence of
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 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
chipper cone or shredder hopper areas.
21. Never continue to operate the machine if it starts
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.
23. Never attempt to perform any maintenance, repairs,
or attachment of accessories while the unit is running.
Always shut the unit off, allow the rotor to come to a
complete stop, and remove the spark plug wire from the
spark plug before beginning these activities.
24. Always make sure that the shredding chamber, shredder
hopper, and chipper cone are empty before starting
the unit after it has been idle. Attempting to start the
unit with material in these areas could cause the engine
starting cord to stop suddenly, injuring your hand and
fingers, or toppling the unit over. Vibration is generally a
warning sign of trouble.
25. Before cleaning, repairing, or inspecting, shut off the
engine and make certain that all moving parts have

Operation
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
Select an area with firm, 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.
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
and wipe up any spills.
WARNING
To avoid serious personal injury from rotating cutting
blades, keep hands out of inlet while machine is
running.
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.
Do not use gasoline containing METHANOL,
gasohol containing more than 10% ETHANOL,
gasoline additives, or white gas because
engine/fuel system damage could result.

running it for at least a minute.
6. Set throttle to FULL and begin chipping/shredding.
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.

Permitted
Size Limitations Notes
Shredding Dry or moist organic material
including leaves, plants,
flowers, fruits, or vegetables.
Branches and twigs up to 1/2”
diameter and 18” long.
Alternately chip or shred moist green waste
with dry waste to avoid plugging of the
discharge chute.
Process at a feeding rate that allows the
rotor to keep up and maintain a high rate
of speed.
Chipping Long, thicker tree limbs or
small bunches of smaller
sticks grouped together for
ease of handling.
Tree limbs and branches,
or bundles of small sticks
grouped for easier handling.
Maximum diameter of
approximately 3” (7,6 cm).
Bulky tree limbs should be pruned close
to the main stem. Always use a shorter
piece of wood to push end pieces into the
chipper cone. Never place hands in the
chipper cone.
Never chip very hard or dry materials such
as kiln dried dimensional lumber (2x4’s etc.)
or other building materials.
Never use the chipper to process pressure-
treated wood products.
Vacuum
Attachment
Light, loose, dry waste such
as leaves, grass clippings, or
sawdust.
Small materials that will not
obstruct the vacuum hose.
The vacuum is engineered for small, loose
waste and for cleaning around decorative
landscaping and flower beds. Twigs, wet
leaves, and other bulky materials will
clog the hose or obstruct the shredding
chamber.
