Cleaning the Radiator
The engine may overheat if the radiator 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
negative
battery terminal disconnected.
AIR CLEANER
Periodic cleaning/replacement is necessary. Inspect the
air cleaner in accordance with the
Isuzu 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
Isuzu Engine Owner’s Manual
.
The fan belt tension is proper if the fan belt bends
10 to 15 mm when depressed with the thumb as shown in
Figure 44. Fan Belt Tension
CAUTION
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
replenishment is necessary.
DO NOT
overfill. Check to see whether the battery cables
are loose. Poor contact may result in poor starting or
malfunctions.
ALWAYS
keep the terminals firmly tightened.
Coat the terminals with an approved battery terminal
treatment compound. Replace the battery with only the
recommended type battery. The battery type used in this
generator is BCI Group 27.
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.
Before charging the battery with an external electric source,
be sure to disconnect the battery cables.
Battery Cable Installation
ALWAYS
be sure the battery cables (Figure 45) are
properly connected to the battery terminals as shown below.
The
red cable
