PRODUCT SPECIFIC SAFETY
DANGER: THE CHIPPER SHREDDER HAS SPINNING BLADES THAT CAN AMPU-
TATE HANDS AND FEET. DO NOT PLACE HANDS OR FEET IN THE HOPPER OR
CHIPPER CONE, OR DISCHARGE CHUTE.
WARNING: THIS UNIT DISCHARGES DEBRIS AT HIGH SPEEDS. ALWAYS WEAR
PROTECTIVE GOGGLES AND DO NOT OPERATE WITHOUT THE DEBRIS BAG IN
PLACE.
Do not allow anyone in the area while the unit is running. If someone does enter the area, shut the unit off immedi-
ately until they leave. Organize the work area prior to starting work.
1. Do not operate without the debris bag in place because this unit discharges debris at high speeds. If the unit is
operated on hard ground, asphalt, concrete, or other hard surfaces without the collection bag in place. Material-
can ricochet off of the hard surface and cause an unsafe condition for users and bystanders.
2. Never leave the machine running unattended. Always turn off the engine, wait for the rotor to come to a com-
plete stop, and disconnect the spark plug before leaving the area. Always move the unit to a safe storage area
when not in use.
3. Never direct discharge material toward anyone. Avoid discharging material against a wall or obstruction. Material
may ricochet back toward the operator.
4. 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.
5. 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.
6. 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.
7. Never allow material to build up around the engine during chipper shredder operation. This could result in a
fire,or overheating of the engine.
2

8. 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.
9. Never continue to operate the machine if it starts making unusual noise or vibration. Shut the engine off immedi-
ately,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.
10. 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.
11. 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.
12. 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
awarning sign of trouble.
13. Use only attachments and accessories approved of by the manufacturer of the machine.
14. Make sure chipper shredder is free of debris before starting the engine.
15. Never attempt to make any adjustments while the engine is running.
16. After striking a foreign object, stop the engine, remove spark plug wire, and wait for all moving parts to come to
a complete stop. Thoroughly inspect the machine for any damage, repair the damage before restarting and
operating the machine.
ENGINE SPECIFIC SAFETY
Before cleaning, repairing, or inspecting, shut off the engine and make certain that all moving parts have come to a
complete stop. Disconnect the spark plug wire and secure the wire away from the spark plug to prevent accidental
starting.
DANGER
1. ENGINES GIVE OFF CARBON MONOXIDE, AN ODORLESS, COLORLESS, POISON GAS. CARBON
MONOXIDE MAY BE PRESENT EVEN IF YOU DO NOT SMELL OR SEE ANY ENGINE EXHAUST. BREATH-
ING CARBON MONOXIDE CAN CAUSE NAUSEA, FAINTING OR DEATH, IN ADDITION TO DROWSINESS,
DIZZINESS AND CONFUSION. IF YOU EXPERIENCE ANY OF THESE SYMPTOMS, SEEK FRESH AIR AND
MEDICAL ATTENTION IMMEDIATELY.
2. IF YOUR MACHINE COMES WITH A SEPARATE ENGINE MANUAL, BE SURE TO READ AND FOLLOW ALL
SAFETY AND WARNING PRECAUTIONS OUTLINED THERE, IN ADDITION TO ANY IN THIS MANUAL.
Handle fuel with care; it is highly flammable.
a. Use an approved fuel container.
b. Never add fuel to a running engine or hot engine.
c. Fill fuel tank outdoors with extreme care. Never fill fuel tank indoors.
d. Replace gasoline cap securely and clean up spilled fuel before restarting.
Preventing Carbon Monoxide Poisoning
1. Always start and run engine outdoors. Do not start or run engine in an enclosed area, even if doors or windows are open.
2. Never try to ventilate engine exhaust indoors. Carbon monoxide can reach dangerous levels very quickly.
3. Never run engine outdoors where exhaust fumes may be pulled into a building.
4. Never run engine outdoors in a poorly ventilated area where the exhaust fumes may be trapped and not easily
taken away. (Examples include: in a large hole or areas where hills surround your working area.)
5. Never run engine in an enclosed or partially enclosed area. (Examples include: buildings that are enclosed on
one or more sides, under tents, car ports or basements.)
6. Always run the engine with the exhaust and muffler pointed in the direction away from the operator.

Gasoline Fires and Handling Fuel Safely
Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive.
1. When storing extra fuel be sure that it is in an appropriate container and away from any fire hazards.
2. Prevent fire and explosion caused by static electric discharge. Use only nonmetal, portable fuel containers
approved by the Underwriter’s Laboratory (U.L.) or the American Society for Testing &Materials.
3. Always fill fuel tank outside in a well ventilated area. Never fill your fuel tank with fuel indoors. (Examples
include: basement, garage, barn, shed, house, porch, etc.) Never fill tank near appliances with pilot lights,
heaters, or other ignition sources. If the fuel has to be drained, this should be done outdoors. The drained fuel
should be stored in a container specifically designed for fuel storage or it should be disposed of carefully.
4. Never remove the fuel cap or add fuel with the engine running. Stop engine and allow to cool before filling.
5. Do not smoke while refueling or operating engine.
6. Never drain fuel from the engine in an enclosed area.
7. Always wipe up excess (spilled) fuel from engine before starting. Clean up spilled fuel immediately. If fuel is
spilled, do not start the engine but move machine and fuel container from area. Clean up spilled fuel and allow to
evaporate and dry after wiping and before starting.
8. Allow fuel fumes/vapors to escape from the area before starting engine.
9. Test the fuel cap for proper installation before starting and using engine.
10. Always run the engine with fuel cap properly installed on the engine.
11. During storage, keep machine so gas cap is up.
12. Never siphon fuel by mouth to drain fuel tank.
13. Always have an adult fill the fuel tank and never allow children to fill the engine.
14. Never allow an adult or anyone under the influence of drugs or alcohol to fill engine.
15. When storing gasoline or equipment with fuel in the tank, store away from furnaces, stoves, water heaters or
other appliances that have a pilot light or other ignition source because they can ignite gasoline vapors.
16. Never fill 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 filling.
17. Remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then
refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.
Burns and Fires
The muffler, muffler guard and other parts of the engine become extremely hot during the operation of the engine.
These parts remain extremely hot after the engine has stopped.
Prevention of Burns and Fires
1. Never remove the muffler guard from the engine.
2. Never touch the muffler guard because it is extremely hot and will cause severe burns.
3. Never touch parts of the engine that become hot after operation.
4. Always keep materials and debris away from muffler guard and other hot parts of the engine to avoid fires.
Children and Bystanders
Tragic accidents can occur if the operator is not alert to the presence of children and/or bystanders. Never assume
that others will remain where you last saw them.
1. Keep the area of operation clear of all persons, especially small children and pets. Keep children under the
watchful care of a responsible adult.
2. Be alert and turn the machine off if children enter the area.
