Generac 0661-4 - Manual (Page 12)

CLEAN AIR INTAKE SCREEN
Clean all foreign material from the air intake screen
(Figure 6) at lease once every 100 hours of operation.
Clean more often
if necessary.
Inspect the area around the generator exhaust muffler
periodically and remove all grass, leaves, dirt, etc.
from this area.
SPARK ARRESTOR MUFFLER
The spark arrestor must be maintained in effective
working order by the vehicle owner/operator.
In the State of California, the preceding is required by
law (Section 4442 of the California Public Resources
Code). Other states may have similar laws. Federal
laws apply on federal lands.
inspect and clean the spark arrestor every 100 hours
of operation.
To remove the spark arrestor, remove the exhaust
tubing connected to the muffler and then remove the
screw that attaches the arrestor to the muffler.
Replace the cone-shaped spark arrestor if torn, perfo­
rated or otherwise damaged.
ENGINE SPARK PLUG
Clean or replace engine spark plug and set gap to
0.030 inch (0.76mm) every 100 hours of operation
(Figure 6). Clean by scraping or wire brushing and
washing with commercial solvent. DO NOT BLAST
CLEAN SPARK PLUG.
Figure 6 — Setting Gap on Spark Plug
SET PLUG GAP AT 0.030 inch
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.
FUEL FILTER
Remove and replace fuel filter (Figure 7) every 100
hours of operation or once each year, whichever
occurs first.

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 problems, and may also conta­
minate the generator fuel system.
BATTERY
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/or tighten as necessary.
Also check battery fluid level, and, if necessary, fill
with DISTILLED 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 automotive type battery
hydrometer.
DANGER: STORAGE BATTERIES 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 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 BAHERY.
DANGER: BAHERY 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 BAHERY. IF
YOU SPILL THE FLUID, FLUSH THE AFFECTED
AREA IMMEDIATELY WITH CLEAR WATER.
