•  Never start or stop the unit with electrical loads connected to

receptacles AND with connected devices turned ON. Start the
engine and let it stabilize before connecting electrical loads.
Disconnect all electrical loads before shutting down the generator.

• Do not insert objects through unit's cooling slots.

• 

Never operate generator:

in rain; in any enclosed

compartment; if connected electrical devices overheat; if electrical
output is lost; if engine or generator sparks; if flames or smoke are
observed while unit is running; if unit vibrates excessively.

Note: Your generator is equipped with a spark arrestor
muffler. The spark arrestor must be maintained in
effective working order by the owner/ operator. In the
State of California, a spark arrestor is required by law
(Section 4442 of the California Public Resources
Code). Other states may have similar laws. Federal
laws apply on federal lands.

Study these 

SAFETY RULES

carefully before installing, operating or

servicing this equipment. Become familiar with this 

Owner’s Manual and

with the unit. The generator can operate safely, efficiently and reliably
only if it is properly installed, operated and maintained. Many accidents
are caused by failing to follow simple and fundamental rules or
precautions.

GENERAC

®

cannot possibly anticipate every possible

circumstance that might involve a hazard. The warnings in this 

manual, and on tags and decals affixed to the unit are, therefore,
not all-inclusive. If you use a procedure, work method or operating
technique GENERAC

®

does not specifically recommend, you must

satisfy yourself that it is safe for you and others. You also must make
sure the procedure, work method or operating technique that you
choose does not render the generator unsafe.

Despite the safe design of this generator, operating this

equipment imprudently, neglecting its maintenance
or being careless can cause possible injury or death.
Permit only responsible and capable persons to
operate or maintain this equipment.

Potentially lethal voltages are generated by these
machines. Ensure all steps are taken to render
the machine safe before attempting to work on
the generator.

 

Parts of the generator are rotating and/or hot during

operation. Exercise care near running generators.

 

GENERAL HAZARDS 

 

• For safety reasons, GENERAC

®

recommends that the installation,

initial start-up and maintenance of this equipment is carried out by
a GENERAC

®

/GUARDIAN

®

Authorized Dealer.

• The engine exhaust fumes contain carbon monoxide, which can be

DEADLY

. This dangerous gas, if breathed in sufficient

concentrations, can cause unconsciousness or even death. This
exhaust system must be installed properly, in strict compliance with
applicable codes and standards. Following installation, you must do
nothing that might render the system unsafe or in noncompliance
with such codes and standards.

• Keep hands, feet, clothing, etc., away from drive belts, fans, and

other moving or hot parts. Never remove any drive belt or fan guard
while the unit is operating.

• Adequate, unobstructed flow of cooling and ventilating air is critical

to correct generator operation. Do not alter the installation or permit
even partial blockage of ventilation provisions, as this can seriously
affect safe operation of the generator. The generator

MUST 

be

operated outdoors.

• When working on this equipment, remain alert at all times. Never

work on the equipment when you are physically or mentally fatigued.

• Inspect the generator regularly, and contact your nearest

GENERAC

®

/GUARDIAN

®

Authorized Dealer for parts needing repair

or replacement.

• Before performing any maintenance on the generator, disconnect its

battery cables to prevent accidental start up. Disconnect the cable
from the battery post indicated by a NEGATIVE, NEG or (–) first.
Reconnect that cable last.

• Never use the generator or any of its parts as a step. Stepping on

the unit can stress and break parts, and may result in dangerous
operating conditions from leaking exhaust gases, fuel leakage, oil
leakage, etc.

IMPORTANT SAFETY INSTRUCTIONS
