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

DCA-400SSK — PRE-SETUP

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 battery disconnected.

Air Cleaner

Periodic cleaning/replacement is necessary. See maintenance section for instruction to cleaning/replacing air cleaner.

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. See maintenance section on replacing belts. To adjust tension:

1.Insert a bar between alternator and the cylinder block to fix alternator in position. When fixing the alternator in position, insert a wooden block between the bar and alternator to prevent damage to the alternator.

2.Loosen bolts and nuts located on the alternator.

3.Move alternator with the bar so the deflection of the belt is approx. 8mm.

4.Tighten the bolt and nuts to fix the alternator back to position.

The fan belt tension is proper if the fan belt bends 7 to 10

mm(Figure 29) when depressed with the thumb as shown below.

Figure 29. Fan Belt Tension

CAUTION :

Never place hands near the belts or fan while the generator set is running.
