Generac Power Systems Air-cooled Industrial Mobile Generator 09843-2 - Manual (Page 14)

Generac IM-72LP Industrial Mobile Generator
CAUTION: Sparking can occur if wire terminal
does not fit firmly over spark plug terminal end. If
necessary, reform wire terminal to obtain a tight fit.
Figure 14 — Engine Spark Plug
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 IM generators do not have
a spark arrestor screen, but are of the more efficient loriod”
or “swirl” 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 muf­
fler cool and install the plug.
WARNING: BE SURE TO RE-INSTALL THE PLUG
FROM THE MUFFLER TIGHTLY. ENGINE VIBRA­
TION COULD CAUSE A LOOSE PLUG TO FALL
OUT. WITHOUT THE PLUG IN PLACE, HOT
ENGINE EXHAUST IS DIRECTED OUT THE OPEN­
ING. 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
FLAMMABLE MATERIAL THIS COULD RESULT IN
A FIRE.
A
CLEANING THE GENERATOR
Keep your generator set as clean and dry as possible. Dirt and
moisture that are permitted to accumulate on electrical wind­
ings 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. Sait, 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
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.
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, 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.
m E¥ERY 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 BAHERIES 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
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 BATTERY.
