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.

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 battery
to crank and start the generator engine. If the
battery has completely discharged, remove it
from the generator for recharging.

Ensure that the 15A and 4A fuses are removed
from the control console, the AUTO/OFF/
MANUAL switch is set to OFF, and the utility
supply to the battery charger is removed before
removing or connecting battery cables. If the
switch is set to AUTO or MANUAL, the genera-
tor can crank and start as soon as the battery
cables are connected.

Be sure the UTILITY power supply to the battery
charger is turned off, or sparking may occur at
the battery posts as the cables are attached and
cause an explosion.
