WARNING

To avoid injury, eye protection and acid-resistant gloves must

be worn when working around batteries. Do not smoke, use

open flame, make sparks or create other ignition sources

around batteries. If a battery is giving off gases, it can explode

and cause injury to personnel. Remove all jewelry such as

rings, ID tags, watches, and bracelets. If jewelry or a tool con-

tacts a battery terminal, a direct short will result in instant

heating, damage to equipment, and injury to personnel.

Sulfuric acid contained in batteries can cause serious burns. If

battery corrosion or electrolyte makes contact with skin, eyes

or clothing, take immediate action to stop the corrosive burn-

ing effects. Failure to follow these procedures may result in

death or serious injury to personnel.

CAUTION

If battery compartment is corroded, it will be necessary to

remove batteries and clean compartment to remove acid resi-

dues and corrosion.

Buildup of dirt or corrosion on batteries can lead to electrical

malfunctions.

Service batteries as follows:

a. Access batteries inside battery box on left side of machine.

b. Check battery hold-down for looseness, corrosion or damage.

Tighten if loose.

c. Clean top of batteries with a rag (Item 28, WP 0184 00).

d. Inspect batteries for evidence of cracked case and electrolyte

leakage.

e. Disconnect battery cables (WP 0080 00).

f. As required, use a solution of 1-1/2 cups (340 grams) of baking

soda (Item 32, WP 0184 00) with 1 gallon (3.8 l) of clean water to

remove any acid film from batteries. Rinse with clean water.
