• DO NOT recharge a weak battery while it is
installed in the generator. Remove battery from
generator and recharge in a well-ventilated area,
away from fuel vapors, sparks, heat or flames.
• Battery electrolyte fluid is an extremely caustic
sulfuric solution that can cause severe burns. DO
NOT permit fluid to contact eyes, skin, clothing,
painted surfaces, wiring insulation, etc. If any bat-
tery fluid is spilled, flush the affected area with
clear water immediately.
• Always wear safety glasses, rubber apron and
gloves when handling a battery.
• Batteries give off explosive hydrogen gas while
charging. The gas can form an explosive mixture
around the battery for several hours after charging.
Any spark, heat or flames can ignite the gas and
cause an explosion which can shatter the battery,
causing blindness or other serious injury.
4.6.3 BATTERY MAINTENANCE
The battery should be inspected per the “Service
Schedule,” Section 6. The following procedure
should be followed for inspection:
1. Inspect the battery posts and cables for tightness
and corrosion. 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 bat-
tery 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 smoking, open flame, sparks or any spark
producing tools or equipment near the battery.
Battery 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 battery. If the fluid is spilled, flush
the affected area immediately with clear water.
Spilled electrolyte is to be washed down with
an acid neutralizing agent. A common practice
is to use a solution of one pound (500 grams)
bicarbonate of soda to one gallon (4 liters) of
water. The bicarbonate of soda solution is to be
added until the evidence of reaction (foaming)
has ceased. The resulting liquid is to be flushed
with water and the area dried.
Do not use any jumper cables or booster bat-
tery to crank and start the generator engine. If
the battery has completely discharged, remove
it from the generator for recharging.
Be sure the AUTO/OFF/MANUAL switch is set to
the OFF position before connecting the battery
cables. If the switch is set to AUTO or MANUAL,
the generator can crank and start as soon as
the battery cables are connected.
Be sure the UTILITY power supply is turned off,
or sparking may occur at the battery posts as
the cables are attached and cause an explosion.
4.6.4 BATTERY REPLACEMENT
When replacing batteries, use the same number and
the type of battery that follows:
