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 giv-

ing 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

contacts a battery terminal, a direct short will result in instant heating or

electric shock, injury to personnel, and damage to equipment.

To avoid injury, battery box top cover must be removed after it is opened

to access batteries.

To avoid injury, eye protection, protective clothing, and gloves must be

worn when working around capacitors. Capacitors contain an electrolyte

that is a potassium hydroxide solution. Potassium hydroxide is highly cor-

rosive and can cause serious burns. If capacitor case becomes cracked,

leaking electrolyte can result in fumes that are hazardous to inhale. If elec-

trolyte makes contact with skin, eyes or clothing, take immediate action to

stop the corrosive burning effects. Failure to follow these procedures may

result in death or serious injury to personnel.

Remove all jewelry such as rings, ID tags, watches, and bracelets, when

working around capacitors. If jewelry or a tool contacts a capacitor termi-

nal, a direct short may result, causing instant heating and electric shock at

the point of short circuit. Damage to equipment and injury to personnel

could result.

CAUTION

To reduce battery damage, check battery box for corrosion (greenish/white

powder) and do not jerk or pull on battery cables during visual inspection.

NOTE

Vehicles equipped with arctic heater have four batteries and two capaci-

tors.

a. Release latches and open battery

box top cover. Remove top cover

from vehicle. Open bottom cover.

Check battery box for damaged or

missing batteries, capacitor(s), and

hold-downs.

b. Check for damaged or missing filler

caps.

c. Check for missing, broken, split or

frayed cables.
