injectors.The procedure for changing the filter is as

follows.

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.

connect negative cable from old bat-

tery first and connect to new battery

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.
