Cleaning the Radiator

CAUTION :

When adding coolant or antifreeze to the radiator, do not remove the radiator cap until the unit has completely cooled.

Day-to-day addition of coolant is done from the reserve tank. When adding coolant to the radiator, DO NOT remove the radiator cap until the unit has completely cooled. See Table

13.for engine, radiator, and reserve tank coolant capacities. Make sure that the coolant level in the reserve tank is always between the "H" and the "L" markings.

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.

Table 13. Coolant Capacity

Engine and Radiator	7.4 Gal. (28 Liters)

Reserve Tank	2 Quarts (11.9 Liters)

Operation in Freezing Weather

When operating in freezing weather, be certain that the proper amount of antifreeze (Table 14) has been added.

NOTE

When the anti-freeze is mixed with water, the anti-freeze mixing ratio must be less than 50%.

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.

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.

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.
