(4) If possible, provide shade to protect the unit from direct sunlight.
c.
Operation in Dusty or Sandy Areas.
(1) Protect the unit from dust and sand. Take advantage of all natural barriers which could protect the unit from
blowing dust or sand. Install a canvas cover when the unit is not in operation.
(2) Keep fuel clean. Strain the fuel before adding it to the tank. Make sure fuel storage and transfer cans are
clean.
(3) Check and service the engine/compressor air cleaner often, even though it has a dust discharge valve.
(4) Clean the engine, compressor and compressor heat exchanger cooling fans often. Wipe with clean cloth
dampened with an approved cleaning solvent.
d. Operation in Rainy or High Humidity Conditions.
(1) Store unit in a sheltered area when it is not in use.
(2) Keep fuel clean and free of water. Keep fuel tank full when the unit is not in use to minimize condensation.
(3) Whenever possible protect the unit from direct rainfall when it is operating. Cover the unit with a tarpaulin
suspended about 3 feet above the unit.
(4) Drain the oil/moisture separators often. Press and hold the CONDENSATE DRAIN switch for 10-15 seconds
every half-hour of continuous operation.
e. Operation in Salt Water Areas.
(1) Avoid 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.
(2) Repair any paint damage, such as cracks and chips. Apply standard issue rustproofing material to all
exposed ferrous metal (steel) surfaces. If rustproofing material is not available, apply a light film of oil or
grease to all exposed metal surfaces.
f.
Operation at High Altitudes.
(1) Engine power output will decrease by about 3-1/2 percent for each 1000 feet above sea level. The
compressor will have a similar loss of operation efficiency.
(2) Service the engine/compressor air cleaner often to minimize this loss of efficiency.

FORDING
The air compressor should not be forded in water deeper than one foot. Deeper water would sub- merge the
alternator and damage it.
