Generac Power Systems 005221-0 - Manual (Page 19)

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 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 BATTER-
IES.
3. Have the state of charge and condition checked.
This should be done with an automotive-type bat-
tery hydrometer.
DANGER

Storage batteries 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 shat-
ter 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 caus-
tic 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.

Do not use any jumper cables or booster battery
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 120VAC power supply to the battery
is turned OFF, or sparking may occur at the bat-
tery posts as the cables are attached and cause
an explosion.
BATTERY REPLACEMENT
When replacing batteries, use the same number and
the type of battery that follows:
NOTE:
The BCI number should be located directly on the
