OPERATION IN UNUSUAL WEATHER - Continued
2-9.
b. Extreme Heat
(1) VENTILATION - Provide sufficient room around air compressor to allow proper air cir-
culation. In addition to consuming large quantities of air this unit is air-cooled. Insufficient
air circulation will cause overheating and lower performance.
(2) LUBRICATION - Lubricate in accordance with Lubrication Chart in Chapter 3,
Section I.
(3) COMPRESSOR PUMP AND ENGINE - Keep outside of engine and compressor clean.
Dirt acts as an insulator which prevents heat from escaping into the air.
(a) Inspect engine blower housing for foreign matter that may restrict the flow of air.
(b) Check belt tension frequently, loose belts can cause overheating.
(c) Check oil level frequently. Fill if necessary.
2-10. OPERATION UNDER OTHER CONDITIONS
a. Dusty or Sandy Areas
(1) PROTECTION - Take advantage of natural barriers that will afford protection against
blowing dust or sand. Use a tarpaulin to construct a screen or shelter for the unit. Cover unit
when not operating.
(2) FUEL SYSTEM - Prevent sand from entering fuel tank. Service fuel filter frequently to
keep it free from dirt and grit.
(3) LUBRICATION - When adding or changing oil, remove dirt from around openings. Keep
oil containers covered.
(4) COMPRESSOR PUMP AND ENGINE - Check air cleaners frequently; service or replace
as required.
b. Rainy or Humid Conditions
(1) PROTECTION - High humidity or rainy weather conditions can cause deterioration of
exposed metal parts. Apply an approved preservative to all exposed metal parts.
(2) SERVICE - Drain air receiver tank frequently of all condensation.
If operation is intermittent duty, check compressor pump
oil frequently. Rusting, oil sludging and rapid wear of
running parts will result under these conditions.
