SPARK ARRESTOR MUFFLER

If the generator is not equipped with a spark arrestor

exhaust muffler and is to be used on any forest cov

ered, brush covered or grass covered unimproved

land, you may have to install a spark arrestor. The

spark arrestor must be maintained in effective work

ing order by the vehicle owner/operator.

For assistance in ordering, installing and maintaining

spark arrestor exhaust mufflers, contact your nearest

authorized service facility.

Exhaust mufflers supplied by Generac are spark

arrestor types. Generac exhaust mufflers for RV gen

erators do not have a spark arrestor screen, but are

the more efficient “toroid” or “swirl” type. To remove

carbon and combustion deposits from such mufflers,

remove the PLUG from the muffler and run the engine

for about 15 minutes. Shut engine down, let the muf

fler cool and install the plug.

EVERY SIX MONTHS

WARNING: BE SURE TO RE-INSTALL THE PLUG

FROM THE MUFFLER TIGHTLY. ENGINE VIBRATION

____

COULD CAUSE A LOOSE PLUG TO FALL OUT.

WITHOUT THE PLUG IN PLACE, HOT ENGINE

EXHAUST IS DIRECTED OUT THE OPENING. THIS

HOT EXHAUST, DEPENDING ON THE INSTALLA

TION, COULD BE DIRECTED TO AREAS NOT ABLE

TO WITHSTAND THE EXTREME HEAT SUCH AS

WOODEN FLOOR BOARDS OR OTHER FUMMA-

BLE MATERIALS. THIS COULD RESULT IN A FIRE.

CLEANING THE GENERATOR

Keep your generator set as clean and dry as possible.

Dirt and moisture that are permitted to accumulate on

electrical windings have an adverse affect on the

insulation resistance of those windings.

Moisture that is allowed to remain in contact with

windings will be retained in voids and cracks of the

windings. Dirt makes the problem worse, since it

tends to hold the moisture into contact with the wind

ings. Salt, as from sea air, worsens the problem since

it tends to absorb moisture from the air. The combina

tion of salt and moisture makes a good electrical con

ductor.

CAUTION! Do NOT use a forceful spray of water to

clean the generator. Water will enter the generator

interior and cause probiems, and may also conta

minate the generator fuei system.

BAHERY

All lead-acid storage batteries will discharge when not

in use. Inspect the generator battery as follows:

ONCE WEEKLY

Inspect battery posts and cables for tightness, corro

sion. Clean and^r tighten as necessary.

Also check battery fluid level, and, if necessary, fill

with DISTILLED WATER ONLY. DO NOT USE TAP

WATER IN BATTERY.

Have the battery state of charge and condition

checked by an automotive service facility. This should

be done with an automotive type battery hydrometer.

DANGER: STORAGE BAHERIES GIVE OFF

EXPLOSIVE HYDROGEN GAS. THIS GAS CAN

FORM AN EXPLOSIVE MIXTURE AROUND THE

BAHERY FOR SEVERAL HOURS AFTER CHARG

ING. THE SLIGHTEST SPARK CAN IGNITE THE

GAS AND CAUSE AN EXPLOSION. SUCH AN

EXPLOSION CAN SHAHER THE BAHERY AND

CAUSE BLINDNESS OR OTHER INJURY. ANY

AREA THAT HOUSES A STORAGE BAHERY MUST

BE PROPERLY VENTILATED. DO NOT ALLOW

SMOKING, OPEN FLAME, SPARKS OR ANY

SPARK PRODUCING TOOLS OR EQUIPMENT

NEAR THE BAHERY.

DANGER: BAHERY ELECTROLYTE FLUID IS AN

EXTREMELY CAUSTIC SULFURiC ACID SOLUTION

THAT CAN CAUSE SEVERE BURNS. DO NOT PER

MIT FLUID TO CONTACT EYES, SKIN, CLOTHING,

PAINTED SURFACES, ETC. WEAR PROTECTIVE

GOGGLES, PROTECTIVE CLOTHING AND GLOVES

WHEN HANDLING A BAHERY. IF YOU SPILL THE

FLUID, FLUSH THE AFFECTED AREA IMMEDIATE

LY WITH CLEARWATER.

DANGER: DO NOT USE ANY JUMPER CABLES

OR BOOSTER BAHERY TO CRANK AND START

THE GENERATOR ENGINE. IF ANY BAHERY HAS

DISCHARGED, REMOVE IT FROM THE VEHICLE

FOR RECHARGING.

MAJOR SERVICE MANUAL

To obtain a service manual for your generator, order it

from your dealer/distributor or contact the factory. Be

sure to identify your unit’s MODEL NUMBER and

SERIAL NUMBER.

DRIVE BELTS

The engine drives the generaor rotor by means of a

pulley and drive belt arrangement. The drive train,

drive belt and pulleys are warranted for the life of the

generator. Drive belt tension was properly adjusted

before the unit was shipped from the factory. If you

suspect that drive belt tension is incorrect, contact an

authorized service facility.

EXERCISING THE GENERATOR

Generac recommends that you start and operate the

generator at least once every seven days. Let the unit

run for at least 30 minutes to “exercise” the engine.
