OPERATION IN EXTREME HEAT.
a.
Refer to Chapter 3, Section I for proper lubrication during extreme heat conditions.
b.
Shelter or cover air compressor unit with canvas covers, if available.
c.
Check oil levels In engine and oil separator tank often.
d.
Frequently check cooling fan belts for wear and proper tension.
e.
Frequently check air compressor discharge temperature gage.
f.
Ensure that cooling fins and cooling fan are kept clean and unobstructed.
2-20.
OPERATION IN AREAS OF HIGH HUMIDITY, HEAVY RAIN, OR SALTWATER.
a.
Air compressor units, Inactive for long periods of time In hot and humid weather, are subject to rapid rusting
and accumulation of fungus. Frequently Inspect, clean, and lubricate to prevent deterioration of painted surfaces. Refer to
Lubrication Instructions (see Chapter 3, Section I).
b.
Dampness Increases chances of corrosion. Inspect all surfaces and electrical connections for signs of
corrosion.
c.
Check twice daily for water In oil of both engine and air compressor.

OPERATION IN EXTREME COLD OR SNOW.
a.
General.
(1)
Refer to Lubrication Instructions (see Chapter 3, Section I) for proper lubricants to use In extreme cold.
(2)
Care must be taken when handling cables. Extreme cold weather can cause insulation material on
electrical wire to crack, causing short circuits.
(3)
When parking for any period of time, park in sheltered area out of wind and clean off any buildup of snow or
ice. Place footing of planks or brush under tires to prevent tires from freezing to ground. Ensure that tires are properly
inflated (see paragraph 1-11). Underinflated tires will freeze, resulting in flat spots.
(4)
Use care when placing air compressor unit in motion after shutdown. Thickened lubricants may cause
failure of components. Free tires frozen to ground with care.
(5)
If available, use canvas covers to shield air compressor unit. Keep cover ends off ground to keep them
from freezing to ground.
(6)
Ensure that radiator fins are clear and free of snow buildup. Keep fan belts adjusted to proper tension.
(7)
At temperatures below -4°F (-20°C), engine must be warmed up before starting operations.
