Spark Arrestor Muffler; Miscellaneous Maintenance - Generac Power Systems NP-66LPG Series Owner's Manual

MISCELLANEOUS MAINTENANCE
■ SPARK ARRESTOR MUFFLER
If the generator is not equipped with a spark arrestor exhaust
muffler and is to be used on any forest covered, brush cov¬
ered or grass covered unimproved land, you may have to
install a spark arrestor. The spark arrestor must be maintained
in effective working 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 recreational vehicle gen¬
erators do not have a spark arrestor screen, but are of the more
efficient "toriod" or "swirl" type. To remove carbon and com¬
bustion deposits from such mufflers, remove the PLUG from
muffler and run engine for about 15 minutes. Shut engine.down,
let the muffler cool and install the plug.
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 FLAMMA¬
BLE MATERIAL THIS COULD RESULT IN A FIRE.
■ BATTERY
All lead-acid storage batteries will discharge when not infuse.
Inspect the generator battery as follows: ' .'£>
Once Weekly
Inspect battery posts and cables for tightness, corrosion. Clean
and/or tighten as necessary.
Also check battery fluid level, and, if necessary, fill with DIS¬
TILLED WATER ONLY. DO NOT USE TAP WATER IN
BATTERY.
Every Six Months
Have the battery state of charge and condition checked by an
automotive service facility. This should be done with an auto¬
motive type battery hydrometer.
DANGER: STORAGE BATTERIES GIVE OFF
EXPLOSIVE HYDROGEN GAS. THIS GAS CAN
FORM AN EXPLOSIVE MIXTURE AROUND THE
BATTERY FOR SEVERAL HOURS AFTER CHARG¬
ING. THE SLIGHTEST SPARK CAN IGNITE THE GAS
AND CAUSE AN EXPLOSION. SUCH AN EXPLO¬
SION CAN SHATTER THE BATTERY AND CAUSE
BLINDNESS OR OTHER INJURY. ANY AREA THAT
HOUSES A STORAGE BATTERY MUST BE PROP¬
ERLY VENTILATED. DO NOT ALLOW SMOKING,
OPEN FLAME, SPARKS OR ANY SPARK PRODUC¬
ING TOOLS OR EQUIPMENT NEAR THE BATTERY.
■ CLEANING THE GENERATOR_
Keep your generator set as demand dry as possible. Dirt and mois¬
ture that are permitted to accumulate on electrical windings have
an adverse affect on the insulation resistance of these wincfi ngs.
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 con¬
tact with the windings. Salt, as from sea air, worsens the
problem since it tends to absorb moisture from the air. The com¬
bination of salt and moisture makes a good electrical conductor.
CAUTION! Do NOT use a forceful spray of water to
clean the generator. Water will enter the generator
Interior and cause problems, and may also conta¬
minate the generator fuel system.
-DANGER: BATTERY ELECTROLYTE FLUID
IS AN EXTREMELY CAUSTIC SULFURIC ACID
_SOLUTION THAT CAN CAUSE SEVERE BURNS.
DO NOT PERMIT FLUID TO CONTACT EYES, SKIN,
CLOTHING, PAINTED SURFACES, ETC. WEAR
PROTECTIVE GOGGLES, PROTECTIVE CLOTHING
AND GLOVES WHEN HANDLING A BATTERY. IF
YOU SPILL THE FLUID, FLUSH THE AFFECTED
AREA IMMEDIATELY WITH CLEAR WATER.
DANGER: DO NOT USE ANY JUMPER CABLES OR
BOOSTER BATTERY TO CRANK AND START THE
GENERATOR ENGINE. IF ANY BATTERY HAS DIS¬
CHARGED, REMOVE IT FROM THE VEHICLE FOR
RECHARGING.
