pressure radiator. Keep the radiator cap tight to pre-
vent loss of coolant. Clean and flush the coolant sys-
tem periodically to prevent clogging the passage and
over-heating the engine. When antifreeze is needed,
always use the permanent type.
BATTERY HANDLING

connect negative cable from old bat-
tery first and connect to new battery
last.

- Remove battery from welder by dis-
connecting negative cable first, then
positive cable and battery clamp.

PREVENTING ELECTRICAL DAMAGE
1. When replacing, jumping, or otherwise connecting
the battery to the battery cables, the proper polarity
must be observed. Failure to observe the proper
polarity could result in damage to the charging cir-
cuit. The positive (+) battery cable has a red termi-
nal cover.
2. If the battery requires charging from an external
charger, disconnect the negative battery cable first
and then the positive battery cable before attaching
the charger leads. Failure to do so can result in
damage to the internal charger components. When
reconnecting the cables, connect the positive cable
first and the negative cable last.
PREVENTING BATTERY DISCHARGE
Turn the RUN/STOP switch to stop when engine is
not running.
PREVENTING BATTERY BUCKLING
Tighten nuts on battery clamp until snug.
