a. Radiator Cap Removal
Cover the cap with a thick cloth and turn it slowly counterclockwise to the first stop. When pressure
is completely released, press downward and finish removing cap.
CAUTION
b. Rust Inhibitor
Use only a corrosion inhibitor that is compatible with aluminum. Do not use inhibitors labeled as
"acid neutralizer."
c. Antifreeze
A permanent type (Ethylene Glycol) antifreeze is recommended for use in the cooling system. The
coolant, when mixed as equal parts of water and the recommended antifreeze, will provide
protection to -35º F.

Battery Service

7.
a. General
A 12-volt battery supplies power for operation of the engine electrical system, clearance and panel
lights, and for building up generator voltage. The battery supplied with a new unit is a maintenance
free type. Some of the following topics apply to non-maintenance free type battery, which requires
additional maintenance such as checking liquid levels.
b. Battery Location and Accessibility
The battery is located on a tray mounted to the left front frame. The battery is easily accessible for
service by opening the left front door and removing the lower panel below the door.
c. Battery Care
(1) Never allow a battery which has been removed from a unit to sit on concrete, ground, or metal,
unless proper insulation is provided. A wooden platform or board will provide sufficient insulation.
(2) Maintain stored batteries in a charged condition,
(3) Be sure battery is fastened securely in their compartment to avoid damage from vibration.
(4) If applicable, maintain battery fluid at proper level (see below).
(5) Keep battery terminal posts and lead cable connectors clean.
WARNING
d. Liquid Level (If battery is not a maintenance free type)
The electrolyte in each cell should be above the plates at all times to prevent battery failure.
Check the level of the electrolyte every two weeks. When electrolyte level is low, add pure
distilled water. Do not use hydrant water or any water which has been in contact with a metal
container. Acid should never be added except by skilled battery personal.
CAUTION
NOTE: It is especially important to keep the battery at full charge for cold weather operation. Add distilled water
to the battery in freezing temperatures only when the engine is to operate for several hours. Thoroughly

Revised 08/01
DO NOT add coolant to an extremely hot engine. This can result in a cracked
block or cylinder head.
Never allow sparks or open flame near battery. Avoid spilling electrolyte on
hands or clothing.
Never add any special battery dopes, solutions, or powders.
