Section IV. OPERATION UNDER UNUSUAL CONDITIONS
2-10. OPERATION IN UNUSUAL WEATHER CONDITIONS - cont.
This paragraph contains procedures for the following:
a.
Operation in Extreme Moist Heat
c.
Operation in Salt Air and Sea Spray
b.
Operation in Extremely Dry and Dusty Heat
d.
Operation in Freezing Weather
Operation of the Hose Reel System in unusual weather conditions does not require special operating
procedures. However, the equipment must be protected from weather related hazards. The following
paragraphs describe these hazards and preventive tasks to perform when operating in unusual weather.
a.
Operation in Extreme Moist Heat. Moisture in contact with bare metal surfaces will cause
corrosion. Prolonged exposure to moist heat may cause the growth of fungus on painted surfaces,
wiring, and electrical connections. Before and after use in humid conditions, perform the following
tasks.
WARNING
Avoid skin contact with metal surfaces. Skin in contact with hot metal
surfaces may cause burns.
(1)
Dry hydraulic cylinder rod surface using a clean, dry cloth.
(2)
Moisten cloth with hydraulic oil. Apply a light coat of oil to hydraulic cylinder rod.
(3)
Inspect frame unit and power pack wiring for fungus growth. Inspect interior of metal
enclosures (junction boxes) With electrical power disconnected, remove fungus using a
clean cloth dampened with denatured alcohol.
CAUTION
To prevent slippage of hose reel brake controls, do not apply oil to braking
surface of hose reel or brake pad.
(4)
Spray a light coat of lubricating oil onto bare metal surfaces. Do not apply oil to braking
surface of hose reels or brake shoes.
b.
Operation in Extremely Dry and Dusty Heat. Blowing sand, dust, and dirt can contaminate
the hydraulic system. Sand particle in bearings and between mating surfaces causes premature wear and
component failure. Before and after use in extremely dry conditions, perform the following tasks:
WARNING
Avoid skin contact with metal surfaces. Skin in contact with hot metal
surfaces may cause burns.
