SPARK PLUGS
Reset the spark plug gap or replace the spark plugs as neces-
sary.
1. Clean the area around the base of the spark plugs to keep dirt
1. Clean the area around the base of the spark plugs to keep dirt
and debris out of the engine. Clean by scraping or washing
using a wire brush and commercial solvent. Do not blast the
spark plugs to clean.
2. Remove the spark plugs and check the condition. Replace
the spark plugs if worn or if reuse is questionable. See the
“Service Schedule” section for recommended inspection.
3. Check the spark plug gap using a wire feeler gauge. See the
Specifications section for the required spark plug gap.
BATTERY MAINTENANCE
The battery should be inspected per the Service Schedule section.
The following procedure should be followed for inspection:
1. Inspect the battery posts and cables for tightness and corro-
1. Inspect the battery posts and cables for tightness and corro-
sion. Tighten and clean as necessary.
2. Check the battery fluid level of unsealed batteries and, if
necessary, fill with DISTILLED WATER ONLY. DO NOT USE TAP
WATER IN BATTERIES.
3. Have the state of charge and condition checked. This should
be done with an automotive-type battery hydrometer.
Storage batteries give off explosive hydrogen
gas. This gas can form an explosive mixture
around the battery for several 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 smok-
ing, open flame, sparks or any spark producing
tools or equipment near the battery.

Battery electrolyte fluid is an extremely corro-
sive 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 fluid is spilled, flush the
affected area immediately with clear water.

NOTE:
The BCI number should be located directly on the battery.
BATTERY FLUID
Check battery electrolyte fluid based on the Service Schedule.
Fluid should cover separators in all battery cells. If fluid level is
low, add distilled water to cover tops of separators. DO NOT USE
TAP WATER IN BATTERY.
CLEANING THE STATIONARY EMERGENCY GENERATOR
Keep the generator as clean and as dry as possible. Dirt and
moisture that accumulates on internal generator windings have an
adverse effect on insulation resistance.
Periodically clean generator exterior surfaces. A soft brush may be
Periodically clean generator exterior surfaces. A soft brush may be
used to loosen caked on dirt. Use a vacuum system or dry, low
pressure air to remove any accumulations of dirt. The generator is
housed inside an all-weather enclosure, clean the enclosure with a
soft, damp cloth or sponge and water.
Once each year have the generator cleaned and inspected by a

Service Dealer. That dealer will use dry, low pressure air to clean
internal windings.

Finally, have the insulation resistance of stator and rotor windings
checked. If insulation resistances are excessively low, the genera-
tor may require drying.
