CAUTION

Always premix the antifreeze and clean tap water before adding to the radiator or the overflow tank. It is very important that a precise 50/50 solution be used with this engine year round. This gives proper cooling during hot weather and freezing protection to -34° F (- 37° C).

Cooling solution exceeding 50% ethylene glycol can result in engine overheating and damage to the engine. Coolant solution must be premixed before adding to radiator.

------------------------------------------------------------------------

Periodically remove the dirt from the radiator fins.

Periodically check the fan belt and radiator hoses. Replace if signs of deterioration are found.

BATTERY MAINTENANCE

WARNING

GASES FROM BATTERY can explode.

●Keep sparks, flame and cigarettes

away from battery.

To prevent EXPLOSION when:

●INSTALLING A NEW BATTERY — disconnect negative cable from old battery first and connect to new battery last.

●CONNECTING A BATTERY CHARGER — remove battery from welder by disconnecting nega- tive cable first, then positive cable and battery clamp. When reinstalling, connect

negative cable last. Keep well ventilated.

●USING A BOOSTER — connect positive lead to battery first then connect negative lead to negative battery lead at engine foot.

BATTERY ACID can burn eyes and skin.

● Wear gloves and eye protection and be careful when working near battery.

●Follow instructions printed on battery.

To prevent ELECTRICAL DAMAGE when:

a)Installing a battery.

b)Using a booster.

Use correct polarity - Negative Ground.

To prevent BATTERY DISCHARGE, if you have an ignition switch, turn it off when engine is not running.

------------------------------------------------------------------------

CLEANING THE BATTERY

Keep the battery clean by wiping it with a damp cloth when dirty. If the terminals appear corroded, discon- nect the battery cables and wash the terminals with an ammonia solution or a solution of 1/4 pound (0.1113 kg) of baking soda and 1 quart (0.946 l) of water. Be sure the battery vent plugs (if equipped) are tight so that none of the solution enters the cells.

After cleaning, flush the outside of the battery, the bat- tery compartment, and surrounding areas with clear water. Coat the battery terminals lightly with petroleum jelly or a non-conductive grease to retard corrosion.

Keep the battery clean and dry. Moisture accumula- tion on the battery can lead to more rapid discharge and early battery failure.

CHECKING ELECTROLYTE LEVEL

If battery cells are low, fill them to the neck of the filler hole with distilled water and recharge. If one cell is low, check for leaks.

The battery is a group 45, with a rating of 495 cold cranking amps.
