IMPORTANT SAFETY INSTRUCTIONS
WARNING
Cancer and Reproductive Harm – www.P65Warnings.ca.gov
DANGER
Engine exhaust contains carbon monoxide, a colorless,
odorless, poisonous gas. Breathing carbon monoxide will
cause nausea, dizziness, fainting or death. If you start to feel
dizzy or weak, get to fresh air immediately.
OPERATE ENGINE OUTDOORS ONLY IN A WELL VENTILATED
AREA AND POINT EXHAUST AWAY.
DO NOT operate the engine inside any building, including
garages, basements, crawlspaces, sheds or enclosed
compartments.
DO NOT allow exhaust fumes to enter a confined area through
windows, doors, vents or other openings.
DANGER
Using an engine indoors CAN KILL YOU IN MINUTES. Engine
exhaust contains carbon monoxide. This is a poison you cannot
see or smell.
NEVER use inside a home or garage, EVEN IF doors and
windows are open.
ONLY use OUTSIDE and far away from windows, doors,
and vents.
Install battery-operated carbon monoxide alarms or plug-in
carbon monoxide alarms with battery back-up according to the
manufacturer’s instructions.
DANGER
Operate equipment with guards in place.
Rotating parts can entangle hands, feet, hair, clothing and/or
accessories. Traumatic amputation or severe laceration can
result.
Keep hands and feet away from rotating parts.
Tie up long hair and remove jewelry.
DO NOT wear loose-fitting clothing, dangling drawstrings or
items that could become caught.
WARNING
Operation of this equipment may create sparks that can start
fires around dry vegetation.
A spark arrestor may be required. The operator should contact
local fire agencies for laws or regulations relating to fire
prevention requirements.
WARNING
Sparks can result in fire or electrical shock.
When servicing the engine:
Disconnect the spark plug wire and place it where it cannot
contact the plug.
DO NOT check for spark with the plug removed.
Use only approved spark plug testers.
WARNING
Running engines produce heat. Severe burns can occur on
contact. Combustible material can catch fire on contact.
DO NOT touch hot surfaces.
Avoid contact with hot exhaust gases.
Allow equipment to cool before touching.
Maintain at least 3 ft. (91.4 cm) of clearance on all sides to
ensure adequate cooling.
Maintain at least 5 ft. (1.5 m) of clearance from combustible
materials.
WARNING
Rapid retraction of the recoil cord will pull hand and arm
towards the engine faster than you can let go. Broken bones,
fractures, bruises or sprains could result. Unintentional
startup can result in entanglement, traumatic amputation or
laceration.
When starting engine, pull the recoil cord slowly until
resistance is felt and then pull rapidly to avoid kickback.
DO NOT start or stop the engine with electrical devices
plugged in and turned on.

Fuel Safety
DANGER
GASOLINE AND GASOLINE VAPORS ARE HIGHLY
FLAMMABLE AND EXPLOSIVE.
Fire or explosion can cause severe burns or death.
Gasoline and gasoline vapors:
–Gasoline is highly flammable and explosive.
–Gasoline can cause a fire or explosion if ignited.
–Gasoline is a liquid fuel but it’s vapors can ignite.
–Gasoline is a skin irritant and needs to be cleaned up
immediately if spilled on skin or clothes.
–Gasoline has a distinctive odor, this will help detect potential
leaks quickly.
–Gasoline expands or contracts with ambient temperatures.
Never fill the gasoline tank to full capacity, as gasoline needs
room to expand when temperatures rise.
–In the case of any petroleum gasoline fire, flames should never
be extinguished unless the fuel supply valve can be turned
OFF. By not doing so, if a fire is extinguished and the supply
of fuel is not turned OFF, an explosion hazard could be created.
When adding or removing gasoline:
DO NOT light or smoke cigarettes.
Turn the engine off and let cool for at least two minutes before
removing the gasoline cap. Always loosen the cap slowly to relieve
pressure in the tank.
Only fill or drain gasoline outdoors in a well-ventilated area.
DO NOT pump gasoline directly into the engine at the gas station.
Always use an approved container to transfer the fuel to the
engine.
DO NOT overfill the gasoline tank.
Always keep gasoline away from sparks, open flames, pilot lights,
heat and other sources of ignition.
DANGER
NEVER place a gasoline container, gasoline tank or any
combustible material in the path of the exhaust stream during
operation of the engine.
WARNING
Never use a gasoline container, gasoline tank, or any other fuel
item that is broken, cut, torn or damaged.
