Section IV. OPERATION UNDER UNUSUAL CONDITIONS
2-11. Operation in extreme heat. Make certain the operating area is well ventilated and that there are no obstructions
to prevent cooling air circulation. Provide intake and exhaust fans to ventilate enclosed operating areas.
b. Check drive belt tension frequently. Loose drive belts can result in slippage causing overheating.
Keep the motor. compressor, belt guard, and air receiver tank clean.
c.
2-12. Operation in extreme cold [below 0F (-18C)]. The air compressor unit should be located in a shed, building,
or protected area whenever possible. If unit must be operated outdoors, protect it from prevailing winds with suitable barrier
and cover with tarpaulin when not in use.
b. Avoid sharp bending, kinking, and excessive handling of the air service hose, which will become brittle at low
temperatures.
c. Keep all wiring connections clean and tight. Make sure there are no short circuits. Avoid unnecessary handling
and sharp bending of wires. Wiring insulation tends to become brittle at low temperatures. Protect motor and control box
from snow and ice.
d. Make certain that air receiver tank and air service hose are drained and free of condensate after shutdown to
prevent freezing.
