$ If you run the generator in an area that is confined, or even partially enclosed, the air you breathe could contain a dangerous amounts of
exhaust gas.
To keep exhaust gas from building up, 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 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's electrical system unless an isolation switch that has been installed by a qualified electrician.

Fire and Bum Hazards
• The exhaust system gets hot enough to ignite some materials.
-Keep the generator at least 1 meter (31eet) 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.

Fuel Valve
The fuel valve is located between ihe 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 lever to OFF after stopping the
engine.
Choke Rod
The choke is used to provide an emiched fuel
mixture when cold starting. The choke can be
opened by moving the choke rod to the right
and closed
by moving the choke rod to the
left.
10

Circuit Breaker
The circuit breaker will automatically switch OFF if there is a short circuit or a
significant overload of the generator at the receptacle.
If the circuit breaker is
switched OFF automatically, check that the applicance is working properly
and does not exceed the rated load capacity of the circuit before switching
the circuit breaker
ON again.
Ground Terminal
The generator ground terminal is connected to the frame of the generator,
on a metal non-current carrying parts of the generator, and the ground terminals
of each receptacle.

Oil Alert System DC 12
Ground terminal
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 sale limit, the Oil Alert system will automatically shut down the engine (the engine switch will remain
in the ON
position). The 1500&1300 do not have this feature.
11

Pilot Lamp
The pilot lamp is illuminated when the generator is operating normally.
DC Terminals
The DC terminals may ONLY be used for charging 12 volt automotive type batteries.
The terminals are colored
red to identify the positive(+) terminal and black to identify the negative(-) terminal. The battery must be connected
to the generator
DC terminals with the proper polarity (battery positive to generator red terminal and battery negative to the generator black
terminal.)
DC Circuit Protector
The DC circuit protector automatically shuts off the DC battery charging circuit when the generator is overloaded, when there is a problem with
the battery or the connections between the battery
and the generator are improper.

GENERATOR USE
Connections to a Building's Electrical "'"'"'*'"'""1'
Connections for standby power to a building's electrical system must be made by a qualified electrician. The connection must isolate the
generator power from utility power, and must comply with all applicable laws and electrical codes.
F'!'\W•j;l~llWil Improper connections to a building's electrical system can allow electrical current from the generator to backteeci
into the lltility lines. Such bacldeed may electrocute utility company 'Jll"r~(ers or othern who contact the lines during a power ou!age.
Consult lhe utility company or a qualified electrician.
F1'tli£\ffi@Rl Improper connections to a bliilding's electrical sys~em can allow electrical curren1 Imm the utility company io bacldeeci
into the generator.When utility power is restored, the generator may explode, bum, or cause !ires in the building's electrical system.
In some areas, generators are required by law to be registered with local utility companies. Check local regulations for proper registration and
use procedures.
Generator Ground Circuits
Portable generators have a system ground that connects the generator frame components to the ground terminals in the AC ouiput receptacles.
The system ground is not connected to the AC neutral wire.
Local regulations, codes or laws may require that the ground system be connected to the AC neutral wire. If the generator is tested by a
receptacle tester, it will not show the same ground circuit condition as for a home receptacle.
II local regulations, codes, or laws require the system ground to be connected to the AC neutral wire, consult a qualified electrical or electrical
inspector.Provide him with the electrical wiring diagram in this manual.
The ground terminal can be used to earth the generator or bond the rrame of the generator to the frame of a vehicle, but only if it is required by
local law or electrical code. Before using the ground terminal consult a qualified electrican or electrical inspector for regulations in your area.

AC Applications
Before connecting an appliance or power cord to the generator;
• Make sure that it is in good working order. Faulty appliances or power cords can create a potential for electrical shock.
• If an appliance begins to operate abnormally, becomes sluggish or stops suddenly, turn it off immediately. Disconnect the applicance, and
determine whether the problem
is the appliance, or if the rated load capacity ol the generator has been exceeded.
• Make sure that the electrical rating ol the tool or appliance does not exceed that of the generator, Never exceed the maximum power rating of
the generator. Power levels between rated and maximum may be used for
no more than 5 minutes.
I NOTICE I Substantial overloading wm open the circuit breaker. Exceeding U1e !ime limit for maximum power operation or siigMly
overloading the generator may no! switch thii' circuil breaker OFF, but will shorten the service iiie of the generator.
Limit operation requiring maximum power to 5 minutes.
Maximum power is: See specifications. (Pages 33&34)
For continuous operation, do not exceed the rated power.
Rated power is: See specifications. (Pages 33&34)
