b. Sand and Dust.
(1) Thoroughly clean and dry vehicle, in-
cluding power plant compartment.
(2) Lubricate vehicle as prescribed in ap-
pendix G. Be sure to force out any dirty
lubricant.
(3) Check for chipped paint. Have unit
maintenance personnel prime and paint any
area where paint is etched or chipped.
(4) Cover entire vehicle with tarpaulin, if
possible. If entire vehicle cannot be covered,
protect periscopes against etching by wind-
blown sand. Also, protect engine compart-
ment against entry of sand and dust.
(5) Clean tow winch and boom winch
wire ropes. Do not coat rope with lubricant.
Lubricants mixed with sand create an
abrasive paste that is more damaging to wire
rope than the lack of lubricant.
(6) Disassemble and clean machine gun
at least once each day. Remove lubricants on
exposed and noncritical operating surfaces of
machine gun and mount. This will prevent
windblown sand and dust from sticking to oil
and forming an abrasive. Clean and lubricate
machine gun and mount with CLP lubricant
(item 3, appx D) immediately upon leaving
sandy terrain.
(7) Clean air filter bags daily when
operating in sand or dust. Extreme conditions
may require cleaning filter bags more than
once a day. When air filter baskets are
removed, inspect air separators for clogging.
If clogged, notify unit maintenance personnel.
(8) Clean power plant reservoir drain in
bottom of hull. If drain becomes plugged,
pressure may build up in transmission and
cause violent eruption of oil when transmis-
sion oil level dipstick is removed.
