IMPORTANT SAFETY INSTRUCTIONS

IMPORTANT SAFETY INSTRUCTIONS

! WARNING

Cancer and Reproductive Harm – www.P65Warnings.ca.gov

! DANGER

Generator 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 GENERATOR OUTDOORS ONLY IN A WELL
VENTILATED AREA AND POINT EXHAUST AWAY.

DO NOT operate the generator inside any building, including
garages, basements, crawlspaces and sheds, enclosure or
compartment, including the generator compartment of a
recreational vehicle.

DO NOT allow exhaust fumes to enter a confined area
through windows, doors, vents or other openings.

! DANGER

Using a generator indoors CAN KILL YOU IN MINUTES.
Generator 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.

! 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.

! DANGER

Generator produces powerful voltage.

DO NOT touch bare wires or receptacles.

DO NOT use electrical cords that are worn, damaged or
frayed. Use only Champion electrical cords for proper
application.

DO NOT operate generator in wet weather.

DO NOT allow children or unqualified persons to operate or
service the generator.

Use a ground fault circuit interrupter (GFCI) in damp areas
and areas containing conductive material such as metal
decking.

Connection to your home’s electrical system requires a
listed 30A transfer switch installed by a licensed electrician
and approved by the local authority having jurisdiction. The
connection must isolate the generator from the utility power
and must comply with all applicable laws and electrical
codes.

Install battery-operated carbon monoxide alarms or plug-in
carbon monoxide alarms with battery back-up according to
the manufacturer’s instructions.

! WARNING

Although the generator contains a spark arrester, maintain
a minimum distance of 5 ft. (1.5 m) from dry vegetation to
prevent fires.

! WARNING

Do not use generator for medical and life support uses.

In case of emergency, call 911 immediately.

NEVER use this product to power life support devices or life
support appliances.

NEVER use this product to power medical devices or
medical appliances.

Inform your electricity provider immediately if you or anyone
in your household depends on electrical equipment to live.

Inform your electrical provider immediately if a loss of power
would cause you or anyone in your household to experience
a medical emergency.

IMPORTANT SAFETY INSTRUCTIONS

! WARNING

Spark from removed spark plug wire can result in fire or
electrical shock.

When servicing the generator:

Disconnect the spark plug wire and place it where it cannot
contact the plug or any other metal object.

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.

! CAUTION

Start the generator and allow the engine to stabilize before
connecting electrical loads.

Connect electrical equipment in the off position, and then
turn them on for operation.

Turn electrical equipment off and disconnect before
stopping the generator.

! CAUTION

Improper treatment or use of the generator can damage it,
shorten its life or void the warranty.

Use the generator only for intended uses.

Operate only on level surfaces.

DO NOT expose generator to excessive moisture, dust,
or dirt.

DO NOT allow any material to block the cooling slots.

If connected devices overheat, turn them off and disconnect
them from the generator.

DO NOT use the generator if:

– Electrical output is lost

! WARNING

Rapid retraction of the starter cord will pull hand and arm
towards the engine faster than you can let go. Unintentional
startup can result in entanglement, traumatic amputation or
laceration. Broken bones, fractures, bruises or sprains could
result.

When starting engine, pull the starter 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.

! CAUTION

Exceeding the generator’s running capacity can damage the
generator and/or electrical devices connected to it.

DO NOT overload the generator.

DO NOT tamper with the governed speed.

DO NOT modify the generator in any way.

– Equipment sparks, smokes or emits flames

– Equipment vibrates excessively

! WARNING

Tamper ing with CO Shield™ could result in a hazardous
condition. Removing the CO Shield module will not allow the
generator to start.

100592 - 6250W DUAL FUEL GENERATOR

IMPORTANT SAFETY INSTRUCTIONS

Fuel Safety

! DANGER

GASOLINE, GASOLINE VAPORS AND PROPANE (LPG) 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.

– In any petroleum gas fire, flames should not be extinguished

unless by doing so the fuel supply valve can be turned OFF.
This is because if a fire is extinguished and a supply of
fuel is not turned OFF, then an explosion hazard could be
created.

– Gasoline expands or contracts with ambient temperatures.

Never fill the gasoline tank to full capacity, as gasoline
needs room to expand if temperatures rise.

LPG:

– LPG is highly flammable and explosive.

– LPG is under pressure and can cause a fire or explosion if

ignited.

– LPG is heavier than air and can settle in low places while

dissipating.

– LPG has a distinctive odor added to help detect potential

leaks quickly.

– In any petroleum gas fire, flames should not be extinguished

unless the fuel supply valve is turned OFF. This is because if
a fire is extinguished and a supply of fuel is not turned OFF,
then an explosion hazard could be created.

– When exchanging LPG cylinders, be sure the cylinder valve

is of the same type.

– Always keep the LPG cylinder in an upright position.

– LPG will burn skin if it comes in contact with it. Keep any

and all LPG away from skin at all times.

When adding or removing gasoline:

DO NOT light or smoke cigarettes.

Turn the generator off and let it cool for at least two minutes
before removing the gasoline cap. 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 generator at the gas
station. Use an approved container to transfer the fuel to the
generator.

DO NOT overfill the gasoline tank.

Always keep gasoline away from sparks, open flames, pilot
lights, heat and other sources of ignition.

When starting the generator:

DO NOT attempt to start a damaged generator.

Make certain that the gasoline cap, air filter, spark plug, fuel
lines and exhaust system are properly in place.

Allow spilled gasoline to evaporate fully before attempting to
start the engine.

Make certain that the generator is resting firmly on level
ground.

When operating the generator:

DO NOT move or tip the generator during operation.

DO NOT tip the generator or allow fuel or oil to spill.

When transporting or servicing the generator:

Make certain that the fuel valve is in the OFF position and the
gasoline tank is empty.

For LPG compatible models, be sure that the LPG cylinder is
disconnected and stored securely away from the generator.

Disconnect the spark plug wire.

When storing the generator:

Store away from sparks, open flames, pilot lights, heat and
other sources of ignition.

Do not store generator, gasoline or LPG cylinders near furnaces,
water heaters, or any other appliances that produce heat or
have automatic ignitions.

! WARNING

Never use a gasoline container, gasoline tank, LPG
connector hose, LPG cylinder or any other fuel item that is
broken, cut, torn or damaged.
