Fuel and Oil
This product requires oil and fuel. Attempting to start the engine without oil will ruin
the engine and void the warranty. Work in well ventilated area. Keep cigarettes,
flames or sparks away from the work area or where gasoline is stored.
WARNING! GASOLINE AND PROPANE ARE EXTREMELY FLAMMABLE AND
ARE EXPLOSIVE UNDER CERTAIN CONDITIONS.
KEEP OUT OF REACH OF CHILDREN.
Gasoline and propane fuel and fumes are flammable and potentially explosive. Use proper fuel
storage and handling procedures. Always have multiple ABC class fire extinguishers nearby.
WARNING! FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN
SEVERE IN JURY OR DEATH.
WARNING! THE EXHAUST CONTAINS POISONOUS CARBON MONOXIDE
GAS THAT CAN CAUSE LOSS OF CONSCIOUSNESS AND MAY LEAD TO
DEATH.
CAUTION: FAILURE TO FOLLOW THESE INSTRUCTIONS CAN ALSO
RESULT IN DAMAGE TO THE TOOL AND/OR THE ITEM YOU ARE WORKING
ON.
DANGER
CARBON MONOXIDE
General Precautions
Using a generator indoors WILL KILL YOU IN MINUTES.
Generator exhaust contains high levels of carbon monoxide (CO), a poisonous gas you cannot
see or smell. If you can smell the generator exhaust, you are breathing CO. But even If you
cannot smell the exhaust, you could be breathing CO.
Even when you use a generator correctly, CO may leak into the home.
If you start to feel sick, dizzy, or weak after the generator has been running, move to fresh air
RIGHT AWAY. See a doctor. You could have carbon monoxide poisoning.
Keep the generator and surrounding area clean at all times.

Do not refill the fuel tank or replace the propane cylinder while the engine is running or while the
engine is still hot. Do not operate the generator with known leaks in the fuel system

WARNING! ENGINE AND EXHAUST SYSTEM PARTS BECOME VERY
HOT AND REMAIN HOT FOR SOME TIME AFTER THE ENGINE IS RUN. WEAR
INSULATED GLOVES OR WAIT UNTIL THE ENGINE AND EXHAUST SYSTEM

Work Area
Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
Donotoperatepowertoolsinexplosiveatmospheres,suchasinthepresenceofflammable
liquids, gases, or dust. Generators create sparks which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating a generator. Provide barriers or
shields as needed.
Electrical Safety
Grounded tools must be plugged into an outlet properly installed and
grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do not use any adapter
plugs.
Grounding provides a low-resistance path to carry electricity away from the
user in the event of an electrical malfunction.

General Precautions (cont’d)
Electrical Safety (cont’d)
All connections and conduits from the generator to the load must only be installed by trained and
licensed electricians, and in compliance with all relevant local, state, and federal electrical
codes and standards, and other regulations where applicable.
The generator must be earth-grounded for fixed installations in accordance with all relevant
electrical codes and standards before operation.
Do not attempt to connect or disconnect load connections while standing in water or on wet or
soggy ground.
Do not touch electrically energized parts of the generator and interconnecting cables or
conductors with any part of the body or with any non-insulated conductive object.
Connectthegeneratoronlytoaloadorelectricalsystem(120volt)thatiscompatiblewiththe

Insulate all connections and disconnected wires.
Guard against electric shock. Prevent body contact with grounded surfaces such as pipes,
radiators, ranges, and refrigerator enclosures.
Personal Safety
Stay alert. Watch what you are doing, and use common sense when operating a generator. Do
not use generator while tired or under the influence of drugs, alcohol, or medication. A moment
of inattention while operating generators may result in serious personal injury.

Personal Safety (cont’d)
Avoid accidental starting. Make sure the power switch is in its “OFF” position, and disconnect
the spark plug wire when not in use.
Remove adjusting keys or wrenches before turning the generator on. A wrench or a key that is
left attached to a rotating part of the generator may result in personal injury.

appropriate conditions.
Do not force the generator. Use the correct generator for your application. The correct generator
will do the job better and safer at the rate for which it is designed.
Do not use the generator if the power switch does not turn it on or off. Any generator that cannot
be controlled with the power switch is dangerous and must be replaced.
Generator Use and Care
Make sure the power switch is in its “OFF” position and disconnect the spark plug wire before
making any adjustment, changing accessories, or storing the generator. Such preventive safety
measures reduce the risk of starting the generator accidentally.
Storeidlegeneratorsoutofreachofchildrenandotheruntrainedpersons.Generatorsare
dangerous in the hands of untrained users.
Maintain generators with care. Do not use damagedgenerator.Tagdamagedgenerators“Donot
use” until repaired.
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that
may affect the generator’s operation. If damaged, have the generator serviced before using. Many
accidents are caused by poorly maintained generators.
Use only accessories that are recommended by the manufacturer for your model. Accessories that
may be suitable for one generator may become hazardous when used on another generator.
