Multiquip DCA-40SSAI operation manual Operation in Freezing Weather, Cleaning the Outer 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 the coolant level in the reserve tank is always between the "H" and the "L" markings.

Table 13. Coolant Capacity

Engine and Radiator	4 Gal. (15 L)
Reserve Tank	0.26 Gal. (1L)

Operation in Freezing Weather

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

Table 14. Anti-Freeze Operating Temperatures

Vol %	Freezing Point		Boiling Point
Anti-Freeze	°C	°F	°C	°F
40	-24	-12	106	222
50	-37	-34	108	226

NOTE

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

DCA-40SSAI — PRE-SETUP

Cleaning the Outer 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 radiator 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 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. Never place hands near the belts or fan while the generator is running.

Figure 33. Fan Belt Tension

CAUTION :

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

Adjusting Fan Belt

If the fan belt does not have the 10 to 15 mm defection follow the procedure below to adjust:

Loosen the alternator adjusting plate and alternator mounding bolt.

Pivot the alternator at the mounting bolt toward the engine left or right until the belt reflects the proper tension. Tighten the mounting bolt and the adjusting bolt.
