SAFETY INFORMATION
Generators are designed to give safe and dependable service if operated according to instructions. Read and
understand this owner’s 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.
·Be sure that anyone who operates the generator receives proper instruction. 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.
·lf you run the generator in an areas 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.
SAFETY
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.

by operating the choke lever manually. Pull the rod out toward CLOSED to enrich the mixture for cold starting.
CONTROLS
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.
Before using the ground terminal, consult a qualified electrician, electrical inspector or local agency having
jurisdiction for local codes or ordinances that apply to the intended use of the generator.
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 place of
checking the oil level before each use.
If engine stops or not restart, check the engine oil level (see page 26) before troubleshooting in other areas
CONTROL
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 AC circuit before switching the circuit breaker
ON again.
The circuit breaker may be used to switch the generator AC power ON or OFF.
Voltage selector switch (Dual Voltage System)
The Voltage selector switch switches the main power carrying windings of the generator to produce “120V
- - 12 -

ONLY” or “120V/240V”. If a 240V appliance is connected to the 4-prong receptacle, the switch must be in the
“120/240V” position. If only a 120V appliance is being connected to any of the120V 3-prong receptacles, select
the “120V ONLY” position.
CONTROL
Switch Position
120/240V: The 120Vand 120/240Vreceptacles can be used simultaneously.
120V ONLY: ONLY the 120V receptacles can be used. Do not use the 120/240V receptacle in this position.
The most power will be available at the 30A 120V locking plug receptacle.

GENERATOR
USE
Connections to Building Electrical System
Connections for standby power to a building 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. A transfer switch, which isolates generator power from utility power, is
available through authorized generator dealer.
WARNING
Improper connections to a building electrical system can allow electrical current from the generator to back feed
into the utility lines. Such back feed may electrocute utility company workers or others who contact the lines
during a power outage, and the generator may explode, burn, or cause fires when utility power is restored.
Consult the utility company or a qualified electrician.
Ground Terminal

- - 15 -
The generator ground terminal is connected to the frame of the generator, the metal non-current carrying
parts of the generator, and ground terminals of each receptacle.
Before using the ground terminal, consult a qualified electrical inspector or local agency having jurisdiction for
local codes or ordinances that apply to the intended use of the generator.

USE
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 appliance, and determine whether the problem is the appliance, or if the rated load capacity of
the generator has been exceeded.
·Make sure that the electrical rating of 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 30 minutes.

NOTICE
Substantial overloading will open the circuit breaker. Exceeding the time limit for maximum power operation or
slightly overloading the generator may not switch the circuit breaker OFF, but will shorten the service life of the
generator.
