NOTICE
When the antifreeze is mixed with water, the antifreeze mixing ratio must be less than 50%.
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 it 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(Figure 33) when depressed with the thumb as shown below.

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 are not properly maintained. Add only distilled water when replenishment is necessary.
DO NOT over fill. 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 an approved battery terminal treatment compound. Replace battery with only recommended type battery.
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.
