WARNING
DANGER
Indicates an immediate hazardous situation which, if not
avoided, will result in death or serious injury to the
operator or to bystanders.
WARNING
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury to the
operator or to bystanders.
CAUTION
Indicates a potentially hazardous situation which, if not
avoided, may result in moderate or minor injury to the
operator or to bystanders.
NOTICE

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.

4 Customer Support: 1-866-409-4581
GENERATOR
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
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.

Sparks can result in fire or electrical shock.
Only check for a spark with an approved spark plug
tester.
DO NOT check for a spark with the spark plug
removed.
Disconnect spark plug wire when servicing the
generator.
FIRE
SHOCK
WARNING
Always inspect fuel lines and electrical connections
for defects and damage prior to operating the
generator.
Generators vibrate during normal use. During and
after the use of the generator, inspect the generator
as well as extension cords and connected power
supply cords for damage resulting from vibration.
Repair or replace damaged items as necessary.
DO NOT use plugs or cords that show signs of
damage, such as broken or cracked insulation or
loose or damaged blades.
FIRE
SHOCK
WARNING
This generator produces powerful voltage that can
cause death or injury.
When this generator is used to supply a building
wiring system, it must be installed by a qualified
electrician and connected to a transfer switch as a
separately derived system, in accordance with the
National Electrical Code, NFPA 70.
The generator should be connected through a
transfer switch that switches all conductors other
than the equipment grounding conductor.
The frame of the generator should be connected to
an approved grounding electrode.
FIRE
SHOCK
WARNING
When starting the generator using the starter cord,
the starter cord can retract rapidly and cause injury.
Be sure to release the starter cord after pulling and
move back away from the generator.

GENERATOR
Generator surfaces become hot during operation.
Hot surfaces can cause severe burns.
DO NOT touch hot surfaces.
Avoid hot exhaust.
Ensure that exhaust vent is not obstructed.
Allow the generator to cool before touching.
Generator could ignite nearby materials.
Maintain at least 5 feet of clearance around and
above the generator.
DO NOT place a storage cover on the unit during
operation. Only place a cover on the generator after
it has thoroughly cooled down.
FIRE
HOT SURFACE
WARNING
Generator must be placed on a firm level surface.
If generator is not level, it could shut off, suffer
decreased performance, and damage property.
WARNING
Always make sure the generator is properly
grounded.
The faceplate of your generator is marked with the
grounding symbol (as shown above), located above
the grounding terminal.
Attach a heavy gauge copper wire (12 AWG
minimum) to this terminal and link it to a copper rod
driven into the ground. Consult an electrician to
ensure compliance with local codes and regulations.
CAUTION
Engine oil must be added prior to starting generator
and the proper level must be maintained.
Failure to add or maintain proper oil level voids your
warranty.
OIL
CAUTION
DO NOT exceed generator’s capacity.
Overloading can damage the generator and the
electrical equipment connected to it.
After starting the generator, allow the motor to
stabilize.
Connect devices in the OFF position, one at a time.
Before turning the generator off, turn off the devices
and disconnect them from the generator.

FEATURES
Oil Alarm
The Oil Alarm system is designed to prevent the engine from
being damaged because of a lack of oil in the crankcase. Before
the oil level falls to an unsafe level, the low oil light will come on
and the engine will shut off.Although the engine is automatically
shut off, the engine switch will still remain in the ON position.
If the low oil light comes on, turn off the generator immediately
and add the proper amount of oil to the engine.
Refer to the Maintenance Schedule and the Engine Oil section.
V.F.T. Digital Meter Display
The V.F.T. digital meter displays the running voltage, the running
frequency and both the current time of use and the continuous
time of use for maintenance purposes.
Circuit Breaker
The circuit breaker protects the individual circuit protectors and
the 30A 120V/240V receptacle. The circuit breaker will
automatically switch OFF if the circuit is overloaded or if the
appliance plugged into the circuit is faulty. If the circuit breaker is
switched OFF automatically, check that the appliance is working
properly and that it does not exceed the rated load capacity of the
circuit before switching the circuit breaker ON again.
Circuit Protector
The circuit protectors will automatically switch OFF if the individual
circuit is overloaded or the appliance plugged into the circuit is
faulty. If the circuit protector is switched OFF automatically, check
that the appliance is working properly and that it does not exceed
the rated load capacity of the circuit before resetting the circuit
protector by pressing the reset buttons.
