MISCELLANEOUS MAINTENANCE
SPARK ARRESTOR MUFFLERS
If the generator is not equipped with a spark arrestor 
exhaust muffler and is to be used on any forest covered, 
brush covered 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 ar
restor types. Generac exhaust mufflers for RV gener
ators do not have a spark arrestor screen, but are of the 
more efficient “toroid" or “swirP type. To remove carbon 
and combustion 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.
A
WARNING: BE SURE TO RE-INSTALL THE
PLUG FROM THE MUFFLER TIGHTLY. EN
GINE 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 EX
TREME 
HEAT
SUCH
AS
WOODEN
FLOOR
BOARDS OR OTHER FLAMMABLE 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 insu
lation resistance of those windings.
Moisture that is allowed to remain in contact with wind
ings 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 windings. Salt, as from 
sea air, worsens the problem since it tends to absorb 
moisture from the air. The combination of sait 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 contami
nate the generator fuel system.
BATTERY
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
DISTILLED
WATER
ONLY.
DO
NOT
USE
TAP
WATER IN BATTERY.
Every Six Months: Have battery state of charge and
condition checked by automotive service facility. This 
should be done with automotive type battery hydrome
ter.

IMMEDIATELY
WITH
CLEAR WATER.
A
DANGER: DO NOT USE ANY JUMPER CA
BLES OR BOOSTER BATTERY TO CRANK
AND START THE GENERATOR ENGINE. IF ANY
BATTERY HAS DISCHARGED, REMOVE IT FROM
THE VEHICLE FOR RECHARGING.
