This manual provides information regarding the operation and maintenance of these products.
We have made every effort to ensure the accuracy of the information in this manual.

We reserve the right to change this product at any time without prior notice.

1

The generator is a potential source of electrical shock if misused. Do not expose the generator to
moisture, rain or snow. Do not let the generator get wet, and do not operate it with wet hands.

These labels warn you of potential hazards that can cause serious injury. Read them carefully.

SAFETY

INFORMATION

Read and understand this instruction manual before operating your generator. You can help prevent
accidents by being familiar with your generator’s controls, and by observing safe operating
procedures.

Operator Responsibility

Know how to stop the generator quickly in case of emergency.
Understand the use of all generator controls, output receptacles, and connections.
Do not let children operate the generator without parental supervision.

Carbon Monoxide Hazards

Exhaust contains poisonous carbon monoxide, a colorless and odorless gas. Breathing exhaust

can cause loss of consciousness and may lead to death.

If you run the generator in an area that is confined, or even partially enclosed, the air you breathe

could contain a dangerous amount of exhaust gas. To keep exhaust gas from accumulating,
provide adequate ventilation.

Electric Shock Hazards

The generator produces enough electric power to cause a serious shock or electrocution if misused.

Using a generator or electrical appliance in wet conditions, such as rain or snow, or near a pool or
sprinkler system, or when your hands are wet, could result in electrocution. Keep the generator dry.
If the generator is stored outdoors, unprotected from the weather, check all of the electrical
components on the control panel, before each use. Moisture or ice can cause a malfunction or short
circuit in electrical components, which could result in electrocution.
Do not connect to a building electrical system unless a qualified electrician has installed an isolation

switch.

Fire and Burn Hazards

The exhaust system gets hot enough to ignite some materials.

－Keep the generator at least 3 feet (1 meter) away from buildings and other equipment during

operation.

－Do not enclose the generator in any structure.
－Keep flammable materials away from the generator.

The muffler becomes very hot during operation and remains hot for a while after stopping the

engine.

Be careful not to touch the muffler while it is hot. Let the engine cool before storing the generator
indoors.

Gasoline is extremely flammable and is explosive under certain conditions. Do not smoke or allow

flames or sparks where the generator is refueled or where gasoline is stored. Refuel in a
well-ventilated area with the engine stopped.

Fuel vapors are extremely flammable and may ignite after the engine has started. Make sure that

any spilled fuel has been wiped up before starting the generator.

.

Engine Key
To start and stop the engine.

Key position:
OFF: To stop the engine. Key can be removed / inserted.
ON: To run the engine after starting, or to pull start the unit.
START: To start the engine by operating the starter motor.

Do not turn the key switch to START position when the engine is running to
prevent damage to the starting motor.

Recoil Starter
To start the engine, turn the key to on, pull the starter grip lightly until resistance is felt, then pull briskly.

Do not allow the starter grip to snap back against the engine. Return it gently to prevent damage to the starter.

Fuel Valve Lever
The fuel valve is located between the fuel tank
and carburetor. When the valve lever is in the ON
position, fuel is allowed to flow from the fuel tank
to the carburetor. Be sure to return the fuel valve
lever to the OFF position after stopping the
engine.

Choke Rod
The choke is used to provide an enriched fuel
mixture when starting a cold engine. It can be
opened and closed by operating the choke rod
manually. Pull the rod out toward CLOSED to
enrich the mixture for cold starting

Voltage Selector Switch
The voltage selector switch switches the main power carrying windings of the generator to produce
‘‘120V ’’ or ‘‘120/240V’’. If a 240V appliance is connected to the 4-prong receptacles, the switch
must be in the ‘‘120/240V’’ position. If only a 120V appliance is being connected select the "120V"
position.

Switch Position

120/240V: The 120V and 120/240V receptacles can be used simultaneously.

120V: Do not use the 120/240V twist lock receptacle in this position. The most power will be available

at the 50A 120/240V receptacle.

6

Change the Voltage Selector Switch after turning the AC circuit breaker to OFF. The generator may
be damaged if the Voltage Selector Switch is changed with the breaker in the ON position.

Ground Terminal
The generator ground terminal is connected to the frame of the generator, the metal
non-current-carrying parts of the generator, and the ground terminals of each receptacle.

DC Receptacle

The DC receptacle may ONLY be used for charging 12 volt automotive type batteries.

The battery must be connected to the generator DC receptacle with the proper polarity (battery
positive to generator positive (+) and battery negative to the generator negative (-).

Do not start the vehicle while the battery charging cable is connected and the generator is running.
The vehicle or the generator may be damaged.

DC Circuit Protector
The DC circuit protector automatically shuts off the DC battery charging circuit when the DC
charging circuit is overloaded, when there is a problem with the battery, or when the connections
between the battery and the generator are improper.

Oil Alert System
The Oil Alert system is designed to prevent engine damage caused by an insufficient amount of oil in
the crankcase. Before the oil level in the crankcase can fall below a safe limit, the Oil Alert system
will automatically stop the engine (the engine switch will remain in the ON position). The Oil Alert
system should not take the place of checking the oil level before each use.

If the engine stops and will not restart, check the engine oil level before troubleshooting in other areas.

AC Circuit Breaker
The AC circuit breaker will automatically switch OFF if there is a short circuit or a significant
overload of the generator at the receptacle. If the AC circuit breaker is switched OFF automatically,
check that the appliance is working properly and does not exceed the rated load capacity of the circuit
before switching the AC circuit breaker ON again. The AC circuit breaker may be used to switch the
generator power ON or OFF.

AC Circuit Protector
The AC circuit protectors will automatically switch OFF if there is a short circuit or a
significant overload of the generator at the 20A 120V, 30A 120V plug. If an AC circuit
protector switches OFF automatically, check that the appliance is working properly and
does not exceed the rated load capacity of the circuit before resetting the AC circuit
protector ON.
