BEFORE STARTING THE

ENGINE

Add Oil

CAUTION! Any attempt to crank or start the engine

before it hasbeen properly filled with the recommended

oil may result in an engine failure.

To fill your engine with oil:

• Place generator on a level surface.

• Follow the oil grade recommendations and oil fill

instructions given in the engine owner's manual.

NOTE:The generator's revolving field rides on a

prelubricated and sealed ball bearing that requires no

additional lubrication for the life of the bearing.

Add Gasoline

_ ARNING! NEVER fill fuel tank indoors. NEVER

fill fuel tank when engine is running or hot.Allow

unit to cool for two minutes before refueling. DO

NOT light a cigarette or smoke when filling the fuel

tank.

_ WARNING! DO NOT overfill the fuel tank.

Always allow room for fuel expansion.

• Use regular UNLEADED gasolinewith the generator

engine.DO NOT usepremium gasoline.DO NOT mix

oil with gasoline.

• Clean area around fuel fill cap,remove cap.

• Slowly add unleaded regular gasoline to fuel tank. Be

careful not to overfill.Allow about 1.5"of tank spacefor

fuel expansion (Figure 2).

Fuel

..... N 22Nr

• Install fuel capand wipe up any spilled gasoline.

IMPORTANT: It is important 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

gasohol,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.

Be sure to review the precautions given in "Storage" on

page 12.NEVER useengine or carburetor cleaner products

in the fuel tank or permanent damagemay occur.

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

)rovided on the generator end (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. Be careful to keepthe grounding wire attached after

connecting the stranded copper wire. However, local codes

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,especiallywhen the unit is

equipped with a wheel kit. 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 receptacles

AND with the connected devicesturned ON.

Starting the Engine

Disconnect all electrical loadsfrom the generator. Use the

following start instructionsteps by numerical order:

COLD WEATH ER

OPERATION

Under certain weather conditions (temperatures below

40°F [4°C] and a high dew point), your generator may

experience icingof the carburetor and/or the crankcase

breather system.

Build a structure that wilt enclose three sides and the top

of the generator:

• Make sure entire muffler-side of generator is exposed.

Note that your generator may appear different from that

shown in Figure9.

• Ensure a minimum of two feet clearance between open

side of box and nearest object.

• Face exposed end away from wind and elements.

• Enclosure should hold enough heat created by the

generator to prevent problems.

_ AUTION! NEVER run unit indoors. DO NOT

enclose generator any more than shown. Remove

generator from shelter when temperature is above

40°F [4°C].

DON'T OVERLOAD YOUR

G EN ERATO R

Capacity

You must make sure your generator cansupply enough

rated (running) and surge (starting) watts for the itemsyou

will power at the sametime. Follow these simple steps:

I. Select the itemsyou wilt power at the same time.

2. Total the rated (running) watts of these items.Thisis

the amount of power your generator must produce to

keep your itemsrunning. SeeFigure I0.

3. Estimate how many surge (starting) watts you wilt

need.Surgewattage isthe short burst of power

needed to start electric motor-driven tools or

appliancessuch asacircular saw or refrigerator.

Becausenot all motors start at the sametime, total

surge watts can be estimated by addingonly the

item(s)with the highest additional surge watts to the

total rated watts from step 2.

Power Management

To prolong the life of your generator and attached devices,

it is important to take care when addingelectrical loads to

your generator.There should be nothing connected to the

generator outlets before starting it's engine.The correct

and safeway to managegenerator power is to sequentially

add loads asfollows:

I. With nothing connected to the generator, start the

engine asdescribed in this manual.

2. Plugin and turn on the first load,preferably the largest

load you have.

3. Permit the generator output to stabilize (engine runs

smoothly and attached device operates properly.

4. Plug in and turn on the next load.

5. Again,permit the generator to stabilize.

6. Repeat steps 4 and 5 for each additional load.

NEVER add more loads than the generator capacity.Take

specialcare to consider surgeloads in generator capacity,

asdescribed above.

GENERAL MAINTENANCE

RECOMMENDATIONS

The Owner/Operator is responsible for making sure that

all periodic maintenance tasks are completed on atimely

basis;that all discrepancies are corrected; and that the unit

is kept clean and properly stored. NEVER operate a

damaged or defective generator.

Engine Maintenance

See engine owner's manual for instructions.

If you need service for your engine, you need to determine

the engine identification number.To do so, remove the

rocker arm cover hood, item number 55 shown on

page 16, by removing the four nuts and washers holding it

in place.The engine model-type-trim number is stamped on

the side of the inner cover attached to the engine. Have

this number in hand when you call the engine service

center for assistance.

A AUTION! Avoid prolonged or repeated skincontact with used motor oil. Used motor oil has

been shown to causeskin cancer in certain

laboratory animals.Thoroughly wash exposed areas

with soapand water.

KEEPOUT OF REACH OF CHILDREN. DON'T

POLLUTE.CONSERVE RESOURCES.RETURN

USED OIL TO COLLECTION CENTERS.

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.

NOTE: DO NOT use a garden hose to clean generator.

Water can enter engine fuel system and cause problems. In

addition, if water enters generator through cooling air slots,

some of the water wilt be retained in voids and cracks of

the rotor and stator winding insulation.Water and dirt

buildup on the generator internal windings will eventually

decrease the insulation resistance of these windings.

To Clean the Generator

A AUTION! NEVER insertany object or tool

through the air cooling slots, even ifthe engine is

not running.

• Use a damp cloth to wipe exterior surfaces clean.

• A soft bristle brush may be used to loosen caked on dirt

or oil.

• A vacuum cleaner may be used to pick up loose dirt and

debris.

• Low pressure air (not to exceed 25 psi) may be used to

blow awaydirt. Inspect cooling air slots and opening on

generator.These openings must be kept clean and

unobstructed.

STO RAG E

The generator should be started at least once every seven

claysand allowed to run at least 30 minutes. If this cannot

be done and you must store the unit for more than

30 days,usethe following guidelinesto prepare it for

storage.

Generator Storage

• Clean the generator asoutlined in"To Clean the

Generator"

• Check that cooling air slots and openings on generator

are open and unobstructed.

_ AUTION! Storage covers canbe flammable.

DO NOT place a storage cover over a hot

generator. Let the unit coot for a sufficient time

before placingthe cover on the unit.

Engine Storage

See engine owner's manualfor instructions.

Other Storage Tips

• To prevent gum from forming in fuel system or on

essential carburetor parts, add fuel stabilizer into fuel

tank and fill with fresh gasoline. Run the unit for several

minutes to circulate the additive through the carburetor.

The unit and fuel can then be stored for up to

24 months. Fuel stabilizer can be purchased locally.

• DO NOT store gasoline from one season to another

unless it has been treated as described above.

• Replace fuel container if it starts to rust. Rust and/or dirt

in fuel can cause problems if it's used with this unit.

• Store unit in a clean and dry area.
