DESCRIPTION
This generator isan engine-driven, revolving field,
alternating current (AC) generator. It was designedto
supply electrical power for operating compatible electrical
lighting, appliances,tools and motor loads.This manual
contains informationfor a generator that operates
120and/or 240Volt, single phase,60 Hz devicesthat
require up to 6,500 watts (6.5 kW) of power that pull up
to 54.2Amps at 120Volts or 27.1Amps at 240Volts.
CAUTION! Do Not exceed the generator's
wattage/amperage capacity.Add up the rated watts of all
devices you are connecting to generator receptacles at one

• Never useworn, bare,frayed or otherwise damaged
electrical cords with the generator. Death, serious injury
and property damagefrom electrical shock may result
•Gasoline is highly FLAMMABLE and its vapors are
EXPLOSIVE. Never allow smoking, open flames,
sparks or heat in the vicinity while handling
gasoline. Avoid spilling gasolineon a hot engine.Comply
with all laws regulating storage and handlingof gasoline.
•Do Not overfitl the fuel tank.Always allow room for fuel
expansion.If tank is overfllled, fuel can overflow
onto a hot engine and cause a FIRE or an
EXPLOSION.
•Never store a generator with fuel in the tank where
gasolinevapors might reach an open flame,spark or pilot
light (ason a furnace, water heater,clothes dryer). FIRE
or an EXPLOSION may result.
• The unit requires an adequateflow of cooling air for its
continued proper operation. Never operate the unit
inside anyroom or enclosure where the free flow of
cooling air intoand out of the unit might be obstructed.
Allow at least2 feet of clearanceon all sidesof generator,
evenwhile operating unit outdoors, or you could damage

while unit is running; if unit vibrates excessively.
GROUNDING THE
G EN ERATO R
The National Electrical Code requires that the frame and
external electrically conductive parts of this generator be
properly connected to an approved earth ground. Local
electrical codes may also require proper grounding of the
unit. For that purpose, a GROUNDING WING NUT is
provided on the generator end (Figure I).
Generally,connecting a No. 12AWG (American Wire
Gauge) stranded copper wire to the grounding wing nut
and to an earth-driven copper or brassgrounding rod
(electrode) provides adequateprotection againstelectrical
shock. Be careful to keep the grounding wire attached after
connecting the stranded copper wire. However, locat codes
may vary widely.Consult with a local electrician for
grounding requirements in your area.
Properly grounding the generator helps prevent electrical
shock ifa ground fault condition exists in the generator or
in connected electrical devices.Proper grounding also helps
dissipatestatic electricity, which often builds up in
ungrounded devices.

DON'T OVERLOAD TH E
G EN ERATO R
Overloading a generator in excess of its rated wattage
capacity can result in damageto the generator and/or
connected electrical devices.Observe the following, to
prevent overloading the unit:
• Add up the total wattage of all electrical devicesto be
connected at one time.This total should NOT be greater
than the generator's wattage capacity.
• If the appliance,tool or motor does not give wattage,
multiply 120Volts times ampere rating to determine
watts (volts x amps = watts).
The rated wattageof lights can be taken from wattage
listed on the lightbulbs.The rated wattageof tools,
appliancesand motors can usually be found on a data
plate or decal affixed to the device.Use Figure 12below
asa general reference.
Someelectric motors, such asinductiontypes, require
about three times more watts of power for starting than
for running.This surge of power lastsfor only a few
secondswhen starting such motors. Be sure you allow
for this high starting wattage when selectingelectrical
devicesto connect to your generator. First figure the
watts needed to start the largest motor.Add to that
figure the running watts of alt other connected loads.
