2-17. Operation In Dusty or Sandy Areas
a. If possible, erect a protective barrier for power
plant. Dust and sand shorten life of equipment
parts and cause mechanical failure. Utilize natural
barriers. Wipe down power plant at frequent
intervals using approved cleaning solvent. If water
is plentiful, wet down surrounding area beyond
immediate operating areas.
b. Lubricate power plant in accordance with
lubrication order. Clean oil fill and level cap and
area around oil tank fill opening frequently to
prevent dust and abrasive material from entering
engine.
c. Keep fuel supply tank cap tightly closed to
prevent dust and sand from entering tank. Clean
area around fuel supply tank cap before removing
cap to add fuel.
d. Inspect and clean collector box engine air inlet
filter daily.
e. Keep all doors and panels on the power plant
closed as much as possible.
2-18. Operation Under Rainy or Humid
Conditions
a. The power plant is weatherized to operate
satisfactorily under rainy or humid conditions.
However, precautions should be observed to insure
protection of the equipment from excessive
moisture.
b. Secure all panels and doors on power plant to
minimize admittance of moisture to power unit
components.
CAUTION
Install anti-icing hose to air intake filter deicer
manifold if temperatures approach freezing.
Adjust compressor air valve periodically to
insure that no ice is forming on the air filter.
c. Close and secure instrument panel access door
(fig. 1-1) after power plant has been started and
adjusted for operation to prevent accumulation of
