b.
With engine stopped, inspect frequently to be sure that engine and compressor lubricating oil levels are at the top
mark on dipsticks. Add oil if necessary to bring oil levels up to the full mark.
c.
Follow unit maintenance procedures In Chapter 4. Refer to Table 4-1, Unit PMCS.
2-15. OPERATION IN DUSTY OR SANDY AREAS.
a.
During refueling and PMCS, be sure that sand or dust is not allowed to enter fuel or lubricating system.
b.
Perform maintenance schedule on engine oil bath air cleaner. (paragraph 3-15 A)
c.
With engine stopped, inspect frequently to be sure that cooling fins are clean and free of dirt. Dirt inhibits cooling.
d.
With engine stopped, inspect frequently to be sure that engine oil is to top mark on dipstick. Add oil as necessary.
e.
Be sure that the frequency of PMCS is increased In accordance with local condition requirements.
2-16. OPERATION IN RAINY OR HIGH HUMIDITY CONDITIONS.
a.
Check that fuel tank cap is tight. Fill tank immediately after every operating period to prevent condensation.
b.
Drain condensate separators every 10-15 minutes.
2-17. OPERATION IN SALT WATER AREAS.
a.
Avoid any direct contact with salt water to prevent corrosion. If salt water does come in contact with the unit, rinse
the unit with clean, fresh water.
b.
Repair any paint damage, such as cracks and chips. Apply standard rustproofing material to all exposed ferrous
(steel) surfaces. If rustproofing material is not available, apply a light film of oil or grease to all exposed metal surfaces.
2-18. OPERATION AT HIGH ALTITUDE.
a.
Engine power output will decrease by about 3 /percent for every 1000 feet of altitude above sea level. The
compressor will have a similar loss of operating efficiency.
b.
Service the engine/compressor air cleaner filters often to minimize this loss of efficiency.
