DCA-150SSKII — PRE-SETUP
Cleaning the Radiator
The radiator may overheat if the fins become overloaded
with dust or debris. Periodically clean the radiator fins with
compressed air. Cleaning inside the machine is dangerous,
so clean only with the engine turned off and the battery
disconnected.
Air Cleaner
Periodic cleaning/replacement is necessary. Inspect it in
accordance with the Komatsu Engine Owner's Manual.
Fan Belt Tension
A slack fan belt may contribute to overheating, or to
insufficient charging of the battery. Inspect the fan belt for
damage and wear and adjust it in accordance with the
Komatsu Engine Owner's Manual.
The fan belt tension is proper if the fan belt bends 7 to 10
mm (Figure 40) when depressed with the thumb as shown
below.

s
Never place hands near the belts or fan
while the generator set is running.
Battery
This unit is of negative ground. DO NOT connect in reverse.

Always maintain battery fluid level between the specified
marks. Battery life will be shortened, if the fluid level is not
properly maintained. Add only distilled water when
6
replenishment is necessary.
The battery is sufficiently charged if the specific gravity of
the battery fluid is 1.28 (at 68°F). If the specific gravity
should fall to 1.245 or lower, it indicates that the battery is
dead and needs to be recharged or replaced.
Check to see whether the battery cables are loose. Poor
contact may result in poor starting or malfunctions. Always
keep the terminals firmly tightened. Coating the terminals
with a thin film of grease will help to inhibit corrosion.
