OPERATION UNDER UNUSUAL CONDITIONS - CONTINUED 0006 00

OPERATE IN EXTREME DRY HEAT (REFER TO FM 90-3, DESERT OPERATIONS)

CAUTION

• Operating during periods of extreme heat [ambient temperatures above 100°F (38°C)] can cause engine

and hydraulic systems to overheat. Engine temperatures above 230°F (110°C) and hydraulic oil

temperatures above 250°F (121°C) can cause damage to engine and hydraulic system components.

Check engine coolant temperature warning light and hydraulic oil temperature warning light often

during periods of extreme heat to prevent damage to engine and hydraulic system.

• Gaskets and seals are more likely to leak when engine and hydraulic system operating temperatures are

high. Check engine and hydraulic oil levels more often during periods of extreme heat to prevent dam-

age to engine and hydraulic system components. Check for leaks around gaskets, seals and fittings more

often.

2. Preparation

. Precautions must be taken to avoid overheating.

a. Contact Maintenance to drain, flush and refill cooling system.

b. Contact Maintenance to lubricate the 6K forklift with correct grade of lubricants.

3. Operation

WARNING

• DO NOT service cooling system unless engine has cooled. This is a pressurized cooling system and escaping

steam or hot coolant will cause serious burns.

• DO NOT remove cooling system radiator cap when engine is hot. Allow engine to cool down. Loosen cap to

first stop and let any pressure out of cooling system, then remove cap. Failure to follow this warning may cause

serious burns.

• Wear effective eye, glove, and skin protection when handling coolants. Failure to do so may cause injury.

a. Check the water temperature gauge at frequent intervals.

b. Check the air cleaner indicator frequently. Have the filter serviced often.

c. Clean and lubricate 6K forklift with correct grade of lubricants to help prevent deterioration. Have Maintenance

change air, fuel, transmission and hydraulic filter elements at shorter than normal intervals, as designated in

Maintenance PMCS.

d. Perform operator PMCS more often than normal (WP 0011 and WP 0012 00).

e. Do not fill fuel tank completely. Extreme heat causes fuel to expand and overflow.

f. Ensure that water is as free as possible of mineral deposits before adding coolant mixture to radiator. Local desert

water sources have high mineral deposits that will clog radiator.

g. Ensure that water/antifreeze mixture is 50/50. This mixture raises coolant boiling point to help prevent overheating.

h. High temperatures can damage hoses. Check radiator, fuel and lubricant hoses for leaks around fittings. Notify super-

visor if hoses are damaged.

i. Park 6K forklift under cover or in the shade, if possible.
