MAINTENANCE
D-4
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
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.
