DESCRIPTION
_Read this manual carefully and become
familiar with your generator. Know its
applications, its limitations and any hazards
involved.
The generators are an engine-driven, revolving field,
alternating current (AC) generator. It was designed to supply
electrical power for operating compatible electrical lighting,
appliances,tools and motor loads.Thegenerator's revolving
field is driven at about 3,600 rpm by a single-cylinder engine.
CAUTION! DO NOT exceed the generator's
wattage/amperage capacity.See"Don't Overload
Generator" on page 12.
Everyeffort hasbeenmade to ensurethat informationinthis
manualisaccurateand current. However,we reserve the
right to change,alter or otherwise improvethe product and
this document at anytime without prior notice.
The EmissionControl Systemfor this generator iswarranted
for standardsset by the Environmental Protection Agency.For
warranty informationrefer to the engineowner's manual.
In the Stateof California a spark arrester isrequired by lawI
(Section 4442 of the California PublicResourcesCode).
Other states may havesimilar laws. Federallawsapply on
federal lands.If you equip the muffler with a spark arrester,
it must be maintained ineffective working order.

before stopping generator.
CAUTION
DO NOT touch hot surfaces.
Allow equipment to cool before touching.
CAUTION
DO NOT tamper with governed speed.Generator supplies
correct rated frequency and voltage when running at governed
speed.
DO NOT modify generator in any way.
Use generator only for intended uses.
tf you have questions about intended use,askdealer or call
1-800-270-1408.

BEFORE STARTING
ENGINE
Add Engine Oil and Fuel
• Placegenerator on a levelsurface.
CAUTION
- Refer to engine manual for oil and fuel fill information.
- Damage to equipment resulting from failure to follow this
instruction will void warranty.
• Refer to engine owner's manualand follow oil and fuel
recommendations and instructions.
NOTE: Check oil often during engine break-in. Refer to
engine owner's manual for recommendations.
NOTE: The generator assembly rotates on a prelubricated
and sealed ball bearing that requires no additional
lubrication for the life of the bearing.
USING THE GENERATOR
System Ground
The generator has a system ground that connects the
generator frame components to the ground terminals on
the AC output receptacles.The system ground isconnected
to theAC neutral wire (the neutral is bonded to the
generator frame).
Special Requirements
There may be Federalor State Occupational Safety and
Health Administration (OSHA) regulations, localcodes,or
ordinances that apply to the intendeduse of the generator.
Pleaseconsult a qualified electrician, electrical inspector,or
the localagencyhaving jurisdiction.
• In some areas,generators are required to be registered
with local utility companies.
• If the generator is usedat a construction site,there may
be additional regulations which must be observed.
Connecting to a Building's Electrical
System
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.
OPERATING THE
G EN ERATO R
CAUTION
See"Don't Overload Generator" on page 12.
Start generator and let engine stabilize before connecting
electrical loads.
Connect electrical loads in OFF position, then turn ON for
operation.
Turn electrical loads OFF and disconnect from generator
before stopping generator.
Starting the Engine
Disconnect all electrical loads from the generator. Follow
these start instruction steps in numerical order:
I. Make sure unit is on a level surface.

surface will cause the unit not to start or shut down
during operation.
2. Turn fuel valve to "On" position (Figure 2).
DANGER
When usinggenerator for backup power, notify utility
company. Use approved transfer equipment to isolate
generator from electric utility.
