Never work on the equipment when physically or mentally
fatigued.
• 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.
EXHAUST & LOCATION HAZARDS
• Never operate in an enclosed area or indoors! NEVER use
in the home, in a vehicle, or in partly enclosed areas such
as garages, even if doors and windows are open! ONLY use
outdoors and far from open windows, doors, vents, and in an
area that will not accumulate deadly exhaust.
• The engine exhaust fumes contain carbon monoxide, which
you cannot see or smell. This poisonous gas, if breathed in
sufficient concentrations, can cause unconsciousness or even
death.
• 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.
• This exhaust system must be properly maintained. Do nothing
that might render the exhaust system unsafe or in noncompliance
with any local codes and/or standards.
• Always use a battery operated carbon monoxide alarm indoors,
installed according to the manufacturers instructions.
• If you start to feel sick, dizzy, or weak after the generator has
been running, move to fresh air IMMEDIATELY. See a doctor, as
you could have carbon monoxide poisoning.
ELECTRICAL HAZARDS
• The generator produces dangerously high voltage when in
operation. Avoid contact with bare wires, terminals, connections,
etc., while the unit is running, even on equipment connected
to the generator. Ensure all appropriate covers, guards and
barriers are in place before operating the generator.
• Never handle any kind of electrical cord or device while
standing in water, while barefoot or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.
• The National Electric Code (NEC) requires the frame and external
electrically conductive parts of the generator be properly
connected to an approved earth ground. Local electrical codes
may also require proper grounding of the generator. Consult
with a local electrician for grounding requirements in the area.
• Use a ground fault circuit interrupter in any damp or highly
conductive area (such as metal decking or steel work).
• Do not use worn, bare, frayed or otherwise damaged electrical
cord sets with the generator.
• In case of accident caused by electric shock, immediately shut
down the source of electrical power. If this is not possible,
attempt to free the victim from the live conductor. AVOID
DIRECT CONTACT WITH THE VICTIM. Use a non-conducting
implement, such as a rope or board, to free the victim from the
live conductor. If the victim is unconscious, apply first aid and
get immediate medical help.
FIRE HAZARDS
• Gasoline is highly FLAMMABLE and its vapors are EXPLOSIVE.
Do not permit smoking, open flames, sparks or heat in the
vicinity while handling gasoline.
• Never add fuel while unit is running or hot. Allow engine to
cool completely before adding fuel.
• Never fill fuel tank indoors. Comply with all laws regulating
storage and handling of gasoline.
• Do not overfill the fuel tank. Always allow room for fuel
expansion. If tank is over-filled, fuel can overflow onto a hot
engine and cause FIRE or an EXPLOSION. Never store generator
with fuel in tank where gasoline vapors might reach an open
flame, spark or pilot light (as on a furnace, water heater or
clothes dryer). FIRE or EXPLOSION may result. Allow unit to
cool entirely before storage.
• Wipe up any fuel or oil spills immediately. Ensure that no
combustible materials are left on or near the generator. Keep the
area surrounding the generator clean and free from debris and
keep a clearance of five (5) feet on all side to allow for proper
ventilation of the generator.
• Do not insert objects through unit’s cooling slots.

PRE-USE CHECK
Prior to starting the generator and adding loads, perform the
following tasks:
1. Make sure the generator is on a firm, level (not to exceed 15°
in any direction), non-combustible surface with at least five
(5) feet of clearance on all sides.

Never operate in an enclosed area or
indoors! NEVER use in the home, in a
vehicle, or in partly enclosed areas such
as garages, even if doors and windows are
open! ONLY use outdoors and far from open
windows, doors, vents, and in an area that
will not accumulate deadly exhaust.
2. Remove the fuel cap and check the fuel level. If fuel is needed,
see the section “FUELING THE GENERATOR”.
3. Remove the left side service cover and check the oil level
by removing the oil filler cap. The oil level should be to the
bottom of the threads on the oil fill pipe. If oil is needed, see
the section “ADDING ENGINE OIL”.
4. Replace and secure the left side service cover.
5. Make sure there are no loads connected to the generator.
6. The National Electric Code (NEC) requires the frame and
external electrically conductive parts of the generator be
properly connected to an approved earth ground. Proper
grounding of the generator will prevent electrical shock in
the event of a ground fault condition in the generator or in
connected electrical devices. Proper grounding also helps
dissipate static electricity, which often builds up in unguarded
devices.
7. Local electrical codes may also require proper grounding of
the generator.
Starting the generator with accessories
connected to the 120 VAC outlets will
damage the generator and the connected
accessories.

NOTE:
When an electric motor is started, the "OVERLOAD" LED may
light up for up to five (5) seconds (this is normal). If it stays on,
a fault has occured. Remove all loads and shut down generator
to reset the alarm. Restart the generator. If the "OVERLOAD"
LED remains lit, contact a Generac Dealer for assistance.
USING THE FLEXPOWER™ SWITCH
When the accessories connected to the generator are going to
be used intermittently (such as a hand drill), the FlexPower™
switch can be pushed to the “ON” (I) position. This will lower the
generator engine speed when loads are not being applied, saving
fuel, reducing engine wear and extending runtime.
USING THE 12 VDC BATTERY CHARGER
The 12 VDC receptacle may be used to recharge 12 VDC
automotive batteries only. The DC charging output is not regulated.
The circuit protector does not prevent over-charging a battery.
1. Connect the charging cable to the generator first, then the
battery, ALWAYS connecting the red lead to positive (+) and
the black to negative (-).

Do not permit smoking, open flame, sparks
or any other source of heat around a battery.
Wear protective goggles, rubber apron
and rubber gloves when working around
a battery. Battery electrolyte fluid is an
extremely corrosive sulfuric acid solution
that can cause severe burns. If a spill occurs,
flush area with clear water immediately.

Storage batteries give off explosive hydrogen
gas while recharging. An explosive mixture
will remain around the battery for a long
time after it has been charged. The slightest
spark can ignite the hydrogen and cause an
explosion. Such an explosion can shatter the
battery and cause blindness or other serious
injury.
NEVER reverse the polarity when connecting
the battery terminals to the charging jack.
Severe damage may occur to the generator
and battery.
2. Keep the FlexPower™ switch in the “OFF” (O) position.
3. Start the generator and use it as normal. Charging time will
vary with battery size and condition. Check the voltage at the
battery terminals once the charging cable has been unplugged
or the generator has been shut down.
NOTE:
This receptacle can not recharge 6-Volt batteries
and can not be used to crank an engine having a
discharged battery.
SHUTTING DOWN
Once the generator is no longer needed it can be shut down.
1. Switch off any accessories connected to the generator. Unplug
any cords to the 120 VAC duplex outlets or the 12 VDC plug.
2. Turn the fuel valve to the “OFF” (O) position (Figure 7). A
switch behind the fuel valve grounds the ignition system,
stopping the engine and the fuel supply is shut off.
3. Close the vent on the fuel cap.
4. Allow the generator to cool before moving or storing.
Always allow the generator to cool off before
storing. High temperatures will be present
at the rear of the unit for some time after
shutdown.

LOW OIL LEVEL SHUTDOWN
This generator is equipped with a low oil level shut down. If the oil
level in the engine crankcase drops below a pre-determined level,
the engine will stop automatically and the “LOW OIL LEVEL” LED
will light up.
Remove the Left Side Service Cover and check the oil level of
the engine. Add or drain oil as necessary; refer to see the section
“ADDING ENGINE OIL”.
FUELING THE GENERATOR
Use care when fueling the generator. Only fill the fuel tank when
the generator has cooled entirely. Use fresh unleaded gasoline with
a minimum Research Octane Number (RON) of 87.
NOTE:
Do not use any gasoline containing more than 10% Ethanol.
NEVER fill the fuel tank with E85 or a mixture of oil and gasoline
designated for two-cycle engines.
Do not light a cigarette or smoke when filling the
fuel tank.

Gasoline is highly FLAMMABLE and its
vapors are EXPLOSIVE. Do not permit
smoking, open flames, sparks or heat in the
vicinity while handling gasoline.

Never fill fuel tank indoors. never fill fuel
thank when engine is running or hot. avoid
spilling gasoline on a hot engine. allow
engine to cool entirely before filling fuel tank.

Do not overfill the fuel tank. Always allow
room for fuel expansion. If tank is over-filled,
fuel can overflow onto a hot engine and
cause FIRE or an EXPLOSION. Wipe up fuel
spills immediately!
TO FILL THE FUEL TANK
1. Remove the fuel tank cap.
2. Add fuel slowly, stopping about two (2) inches below the top
of the filler neck.
3. Replace the fuel tank cap. Make sure the valve on the fuel cap
is in the “OFF” position.
4. If the generator is going to be started, refer to the section
“STARTING THE GENERATOR” for additional directions on
priming the fuel system.

ADDING ENGINE OIL
All oil should meet minimum American Petroleum Institute (API)
Service Class SJ, SL or better. Do not use any aftermarket
additives.
Select the oil's viscosity grade according to the expected operating
temperature.
• Above 40° F, use SAE 30
• Below 40° F to 10° F, use 10W-30
• Below 10° F, use synthetic 5W-30

TO ADD ENGINE OIL TO THE CRANKCASE
1. Place the unit on a firm, level surface (not to exceed 15° in any
direction).
2. Remove the Left Side Service Cover.
3. Remove the oil fill cap located on the bottom of the engine
crankcase.
4. Add the recommended engine oil slowly, stopping frequently
to check the level. The full level is the base of the threads in
the filler neck. DO NOT OVERFILL!
