DANGER
Gasoline and gasoline vapors are highly flammable
and explosive.
Turn generator “OFF” before refueling, and keep it
off during refueling.
Wait several minutes before opening the fuel tank, in
order to allow the generator to cool down.
Only refuel generator outdoors in a well-lit and
well-ventilated area.
If any fuel is spilled, allow it to evaporate before
starting the generator.
DO NOT overfill the fuel tank.
DO NOT smoke or use open flame near the
generator.
EXPLOSION
FIRE
DANGER
Generator voltage is deadly.
There is a danger of electric shock.
Use only undamaged electrical cords.
DO NOT touch bare wires or receptacles.
DO NOT operate generator in wet weather or in wet
conditions.
DO NOT touch generator or cords if hands or feet are
wet.
Your generator is equipped with a ground fault
circuit interrupter (GFCI) and it should always be
used.
Use only approved transfer equipment to attach
generator to your power system. Only a qualified
electrician should install this.
DO NOT plug your generator directly into home or
garage sockets (a practice known as backfeeding).
This can result in death or serious injury to electric
utility workers.
SHOCK
DANGER
Moving parts can cause severe trauma.
Keep hands and feet away from rotating parts, tie up
long hair, remove jewelry, and DO NOT wear loose
clothing.
KICKBACK
DANGER
Generator exhaust contains carbon monoxide (CO).
This is a poison you cannot see or smell.
If you can smell the generator exhaust, you are
breathing CO. But even if you can not smell the
exhaust, you could be breathing CO.
NEVER use a generator inside homes, garages,
crawlspaces, or other partly enclosed areas. Deadly
levels of carbon monoxide can build up in these
areas. Using a fan or opening windows and doors
does NOT supply enough fresh air.
ONLY use a generator outside and far away from
windows, doors, and vents. These openings can pull
in generator exhaust. Even when you use a generator
correctly, CO may leak into the home.
ALWAYS use a battery-powered or battery-backup
CO alarm in 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.

Proper maintenance is the responsibility of the owner.
Your generator requires periodic maintenance and adjustments to
keep the generator in good operating condition. Refer to the
Maintenance Schedule chart for specific maintenance intervals.
eep in mind that this maintenance schedule is for normal
working conditions.
3088054549752!>89,3
Combustion may generate such pollutants as carbon monoxide
(CO), nitrogen oxides and hydrocarbons, which may contaminate
the environment if large amounts of them are emitted into the air.
Among them, CO is a kind of colorless, flavorless and toxic gas.
Excessive inhalation of this poison could lead to serious injury or
death, so it is very important to control emissions. To ensure that
your gasoline engine meets emission standards, consider the
following items.
Unauthorized modification or changes to the emission control
system may lead to illegally high emissions. Unauthorized
modification of the inlet or outlet system or to the speed governing
system connections is prohibited.
Improper maintenance or a failure to correct
problems before operation can lead to malfunctions,
which could cause serious injury or death.
Always follow inspection and maintenance
recommendations and schedules in the owner’s
manual.
WARNING
The maintenance schedule applies to normal
operating conditions. If you operate the generator
under severe conditions such as sustained high load
or high temperature, or use it in unusually wet or
dusty conditions, consult your servicing dealer for
recommendations applicable to your use.
NOTICE
DANGER
Generator exhaust contains carbon monoxide (CO).
This is a poison you cannot see or smell.
If you can smell the generator exhaust, you are
breathing CO. But even if you can not smell the
exhaust, you could be breathing CO.
NEVER use a generator inside homes, garages,
crawlspaces, or other partly enclosed areas. Deadly
levels of carbon monoxide can build up in these
areas. Using a fan or opening windows and doors
does NOT supply enough fresh air.
ONLY use a generator outside and far away from
windows, doors, and vents. These openings can pull
in generator exhaust. Even when you use a generator
correctly, CO may leak into the home.
ALWAYS use a battery-powered or battery-backup
CO alarm in 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.
TOXIC FUME
Always turn off your generator and allow generator
to cool down before performing maintenance.
Remove the spark plug wire before attempting
maintenance. This prevents the generator from
starting unintentionally.
Always follow the recommended maintenance in the
owner’s manual.
