BEFORE STARTING ENGINE
Add Oil
NOTE: When adding oil to the engine crankcase in the
future, use only high quality detergent oil rated with API
service classification SG,SF/CC, CD. Select the oil's
viscosity grade according to your expected operating
temperature:
colder _ 32°F ._warmer
SAE lOW30 SAE30
SAE 10W-30 is recommended for general all temperature
use. Multi-viscosity oils (lOW30, etc.) improvestarting in
cold weather, but these oils will result in increasedoil
consumption. Check your engine oil level more frequently
to avoid possible damagefrom running low on oil.
To Add Engine Oil:
• Placethe generator on a level surface.
• Remove the oil fill cover.
• Remove oil filler capand wipe dipstick clean (Figure I).
Oil Filler Neck
• Ifthe oil level isnot at the point of overflowing from the
oil filler neck, slowly fill enginewith recommended oil.
• Reinstalloil filler capand tighten securely.
• Replacethe oil fill cover.
• Check the engineoil level before starting each time
thereafter.
Add Fuel
A ARNING! NEVERfill fuel tank indoors.NEVER
fillfuel tank when engineisrunning or hot. Allow unit
to cool for two minutesbefore refueling.DO NOT
light a cigaretteor smokewhen fillingthe fuel tank.
_IL WARNING! DO NOT overfill the fuel tank.
Always allow room for fuel expansion.
• Use cleanfresh UNLEADED fuel with a pump rating of
86 or higher. DO NOT usepremium or leaded fuel. DO
NOT mix oil with fuel.
• Clean area around fuel fill cap, remove cap.
• Check the fuel level.
• If fuel levelislow, slowly add recommended fuel to fuel
tank, up to the shoulder of the fuel strainer (Figure 2).
Be careful not to overfill (there should be no fuel inthe
filler neck).
NOTE: Occasionally clear the fuel strainer of anydirt,
rust, or other particulate matter.
• Install fuel cap and wipe up any spilled fuel.
Occasionally you may hear a light "spark knock" or
"pinging" (metallic rapping noise) while operating under
heavy loads. This isno causefor concern. If spark knock or
pinging occurs at a steady engine speed under normal load,
changebrands of fuel or obtain a higher octane rated fuel.
If pingingor spark knock persists, see your local Briggs&
Stratton repair center.
Operation
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 mayalso require proper grounding of the
unit. For that purpose, a GROUNDING WING NUT is
provided on the generator housing (Figure 3).
Grounding Wing Nut
Generally, connecting a No. 12AWG (American Wire
Gauge) stranded copper wire to the grounding wingnut
and to an earth-driven copper or brass grounding rod
(electrode) provides adequate protection against electrical
shock. Becareful to keepthe grounding wire attached after
connecting the stranded copper wire. However, localcodes
may vary widely. Consult with a localelectrician for
grounding requirements in your area.
Properly grounding the generator helps prevent electrical
shock if aground fault condition exists in the generator or
in connected electrical devices. Proper grounding also helps
dissipate static electricity, which often builds up in
ungrounded devices.
OPERATING THE
G EN ERATO R
A AUTION! NEVER start or stop the engine with
electrical loadsconnected to the unit and with the
connected devicesturned ON.
Starting the Engine
Disconnect all electrical loadsfrom the generator. Use the
following start instructions:
• Be sure the spark plug wire is attached to the spark plug.
• Turn the fuel valve to the "Open" position (fully
clockwise) (Figure 4).
• Slidethe choke leverto the "Choke" position (all the
way to the right) (Figure 5).
• Place the engine switch in the "On" position (Figure 6).
• Grasp starter grip and slowly pull the rope untilyou feel
some resistance,then pull the cord out with a rapid full
arm stroke. Let rope return slowly. DO NOT let rope
"snap back" againstthe unit.
Section 4: Operation
NOTE: If engine starts after 3 pulls, but fails to run for
more than l0 seconds, checkfor proper oil level in
crankcase.This unit is equipped with a Oil Alert System
(see page8).
• Slide the choke lever leftto the "Run" position asthe
engine warms up.
NOTE: Under no loadconditions, the engine speed may
vary slightly faster or slower until engine temperatures
stabilize.
_ CAUTION! Breathing Hazard! NEVER run
engine in enclosed poorly ventilated areas.Engine
exhaust contains carbon monoxide, an odorless and
deadlygas.
Connecting Electrical Loads
• Let engine stabilize and warm up for a few minutes after
starting.
• DO NOT connect 240 Volt loadsto 120Volt receptacles.
• DO NOT connect 3-phase loads to the generator.
• DO NOT connect 50 Hz loadsto the generator.
• Plug in and turn on the desired 120Volt AC, single
phase, 60 Hertz electrical loads.
• DO NOT OVERLOAD GENERATOR. Add up the
rated watts (or amps) of all loadsto be connected at
one time. This total should not be greater than the rated
wattage/amperagecapacity of the generator. See "Don't
Overload Generator" on page 10.
Stopping the Engine
• Unplug all electrical loadsfrom the unit. NEVERstart or
stop engine with electrical devices pluggedin and turned
on.
• Let engine run at no-load for two minutes to stabilize
the internal temperatures.
• Move engineswitch to the "Off" position.
• Turn the fuel valveto the "Close" position (fully
counterclockwise).
NOTE: In an emergency,stop the engine by moving the
engine switch to the "Off' position.
Oil Alert System
The Oil Alert Systemisdesignedto prevent engine damage
caused by an insufficient amount of oil in the crankcase.
Before the oil levelin the crankcase can fall below a safe
limit, the Oil Alert Systemwill automatically shut clown the
engine (the engine switch will remain in the "On" position).
Ifthe Oil Alert System shuts clown the engine, add engine
oil.
Charging a Battery
_ ARNING! Storage batteries emit explosive gas
while charging that remains around a battery for a
long time after it hasbeen charged. The slightest
spark can ignite the gas,causingan explosion that
can shatter the battery and cause blindnessor
other injury.
_ WARNING! DO NOT permit smoking, open
flame, sparks or any other source of heat around a
battery. DO NOT use a lighter or other flame for
checking battery fluid levels. Wear protective
goggles, rubber apron and rubber gloves when
working around a battery. Battery electrolyte fluid is
an extremely caustic sulfuric acid solution that can
cause severe burns. DO NOT permit fluid contact
with eyes, skin, clothing, etc. If spill occurs, flush
area with clear water immediately.
Your generator hasthe capability of recharging a discharged
12Volt automotive or utility style storage battery. DO
NOT usethe unit to charge any6 Volt batteries. DO NOT
usethe unit to crank an engine havinga discharged battery.
To recharge 12 Volt batteries, proceed as follows:
• If necessary,cleanbattery posts or terminals.
• Check fluid levelin allbattery cells. If necessary,add
ONLY distilled water to cover separators in battery
cells. DO NOT use tap water.
• If the battery isequipped with vent caps,make sure they
are installed and are tight.
• Connect battery charge cableconnector plug to the
12Volt DC panel receptacle.
• Connect battery charge cableclamp with red handle to
battery post or terminal indicated by Positive, POS or

• Start generator. Let the engine run while battery
recharges.
• When battery hascharged,shut down engine (see
"Stopping The Engine")
NOTE: Use an automotive hydrometer to test battery
state of chargeand condition. Follow the hydrometer
manufacturer's instructionscarefully. Generally, a battery is
considered to be at 100%state of charge when specific
gravity of its fluid (asmeasured by hydrometer) is 1.260or
higher.
CONNECTOR PLUGS
120 Volt AC, 15 Amp Receptacle
Eachoutlet socket isprotected againstoverload by a
7.5Amp push-to-reset circuit breaker. Use each receptacle
to operate 120Volt AC, single phase,60 Hz electrical loads
requiring up to 1,000watts (I.0 kW) of power (Figure8).
_ AUTION! Although each receptacle is rated
for 120Volts at 15Amps (I,440 watts or 1.44kW),
the generator israted for a total of 1,000watts.
Powering loads that exceed the wattage capacity of
the generator can damageit or cause serious
injuries.The total of loadspowered through these
receptacles should not exceed 7.5 Amps.
12 Volt DC Accessory Jack
This receptacle allows you to recharge a 12Vott
automotive or utilitystyle storage battery with the battery
charge cable provided. Camping-style air pumps, lanterns,
fans,or other 12Volt devices havinga cigarette lighter-type
plug may also be powered by this outlet (Figure9).
This receptacle can not recharge 6 Volt batteries and can
not be usedto crank an engine havinga discharged battery.
See "Charging a Battery" (page 8) before attempting to
rechargea battery.
EXTENSION CORDS
Use only high quality,well-insulated, extension cords with
the generator's 120Volt electrical receptacles.
Check the ratings of all extension cords before you use
them. Suchcords should be rated for 125Volt AC loadsat
15Amps (or greater) for most electrical devices.Some
devices, however, may not require this type of extension
cord. Check the owner's manualsof those devicesfor their
recommendations.
Keep extension cords asshort as possible,preferably less
than 15feet long, to prevent voltage drop and possible
overheating of wires.

GENERAL MAINTENANCE
RECOMMENDATIONS
The generator warranty does not cover items that have
been subjected to operator abuse or negligence. To receive
full value from the warranty, operator must maintain
generator as instructed in this manual.
Some adjustments will need to be made periodically to
properly maintain your generator.
All adjustments in this section should be made at least
once each season.Follow the requirements in the
"Maintenance Schedule"chart shown below in Figure I I.
NOTE: Once a year you should cleanor replace the spark
plug and replacethe air filter. A new spark plug and clean
air filter assureproper fuel-air mixture and help your
engine run better and last longer.
GENERATOR
MAINTENANCE
Generator maintenance consists of keeping the unit clean
and dry. Operate and store the unit in a clean dry
environment where it will not be exposed to excessive
dust, dirt, moisture or any corrosive vapors. Cooling air
slots in the generator must not become clogged with snow,
leaves or any other foreign material.
Check the cleanliness of the generator frequently and clean
when dust, dirt, oil, moisture or other foreign substances
are visible on its exterior surface.
NOTE: DO NOT usea garden hose to cleangenerator.
Water can enter engine fuel system and causeproblems. In
addition, if water enters generator through cooling air slots,
some of the water will be retained in voidsand cracks of
the rotor andstator winding insulation. Water and dirt
buildup on the generator internal windings will eventually
decreasethe insulation resistanceof these windings.

STORAGE INSTRUCTIONS
Transporting and Storage
When transporting the generator, turn the engine switch
to "Off' and the fuel valveto "Close". Keep the generator
levelto prevent fuel spillage.
_hL WARNING! Contact with a hot engine or
exhaust system can cause serious burns or fires. Let
the engine coot before transporting or storing the
generator.
Takecare to not drop or strike the generator when
transporting. DO NOT place heavyobjects on the
generator.
The generator should be started at leastonce every seven
daysand allowed to run at least30 minutes. If this cannot
be done and you must store the unit for more than 30 days,
use the following guidelinesto prepare it for storage.
Long Term Storage Instructions
_hL WARNING! NEVER store engine with fuel in
tank indoorsor in enclosed, poorly ventilated areas
where fumes may reach an open flame, spark or
pilot lightason a furnace, water heater, clothes
dryer or other gasappliance.
Be sure the storage area isfree from excessive
humidity and dust.
One Month to One Year
Drain the carburetor float bowl (see following section) and
fuel tank intoa suitable container. After removal from
storage, fill with fresh fuel before starting.
More than One Year
It isimportant to prevent gum deposits from forming in
essentialfuel system parts such asthe carburetor, fuel filter,
fuel hose or tank during storage. Also, experience indicates
that alcohol-blended fuels (called gasohot,ethanol or
methanol) can attract moisture, which leadsto separation
and formation of acids during storage. Acidic gascan
damagethe fuel system of an engine while in storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 daysor longer. Follow these
instructions:
Protect Fuel System
_hL WARNING! Drain fuel into approved container
outdoors, awayfrom openflame. Be sure engine is
cool. DO NOT smoke.
• Drain carburetor float bowl and fuel tank into a suitable
container by looseningthe drain screw (Figure 15).
• Retighten drain screw before refueling.
Change Oil
While engine isstill warm, changeoil asdescribed on
page 12.Refill with recommended grade.
Oil Cylinder Bore
• Remove spark plug and pour about one tablespoon of
clean engineoil into the cylinder.
_llL CAUTION! Avoid sprayfrom spark plug hole
when cranking engine slowly.
• Cover spark plug hole with rag. Crank slowly several
times to distribute oil.
• Install spark plug. DO NOT connect spark plug wire.
• Slowly pull the starter grip until resistance isfelt. At this
point, the piston iscoming up on itscompression stroke
and both the intakeand exhaust valvesare closed.
Storing the engine in this position will help to protect it
from internalcorrosion.
Generator
• Clean the generator asoutlined on page 12 ("To Clean
the Generator").
• Check that cooling air slots and openingson generator
are open and unobstructed.
Other Storage Tips
• DO NOT store fuel from one seasonto another.
• Replacethe fuel can if it starts to rust. Rust and/or dirt
in fuel will causeproblems.
• If possible, store your unit indoors.BE SURE TO
EMPTY THE FUEL TANK.
• Cover your unit with a suitable protective cover that
does not retain moisture.
IMPORTANT: NEVERcover your generator while engine
and exhaust area are warm.
• Store generator in clean, dry area.
