Generac NP-50LPG Recreational Vehicle Generator
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 muffler for recreational vehicle gen­
erators do not have a spark arrestor screen, but are of the more
efficient “toroid" or “swirl” type. To remove carbon and com­
bustion deposits from such mufflers, remove the PLUG from
the muffler and run engine for about 15 minutes. Shut engine
down, let the muffler cool and install the plug.
A
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 installation, 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.
CLEANING THE GENERATOR
Keep your generator set as clean and dry as possible. Dirt
and moisture that are permitted to accumuiate 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 con­
tact with the windings. Salt, as from sea air, worsens the
problem since it tends to absorb moisture from the air. The
combination of salt and moisture makes a good electrical con­
ductor.
BAHERY
All lead-acid storage batteries will discharge when not in use.
The generator battery should be inspected as follows:
■ ONCE WEEKLY___________________ ___
Inspect battery posts and cables for tightness, corrosion.
Clean and/or tighten as needed.
Also check battery fluid level, and, if necessary, fill with DIS­
TILLED WATER ONLY. DO NOT USE TAP WATER IN
BAHERY.
■ EVERY SIX MONTHS_________________________
Have battery state of charge and condition checked. This
should be done with an automotive type battery hydrometer.
A
DANGER: Storage batteries give off explosive
hydrogen gas. This gas can form an expiosive mix­
ture around the battery for severai hours after
charging. The slightest spark can ignite the gas
and cause an explosion. Such an explosion can
shatter the battery and cause blindness or other
injury. Any area that houses a storage battery
must be properly ventilated. Do not allow smoking,
open flame, sparks or any spark producing tools
or equipment near the battery.
DANGER; Battery electrolyte fluid is an extremely
caustic sulfuric acid solution that can cause
severe bums. Do not permit fluid to contact eyes,
skin, clothing, painted surfaces, etc. Wear protec­
tive 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 discharged, remove it
from the vehicle for recharging.
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.
