References
DA Form 2404
FM 90-3
WP 0048
GENERAL
In addition to performing normal Preventive Maintenance Checks and Services (PMCS) (WP 0048), clean and
lubricate equipment more often to compensate for extremes of temperature, humidity, and terrain conditions
that are present or expected. Cleaned and lubricated equipment ensures proper operation and guards against
excessive wear and failure.
When equipment constantly breaks down due to operating under extreme conditions, report failure(s) using
DA Form 2404 (Equipment Inspection and Maintenance Worksheet).
OPERATING IN DUSTY OR SANDY AREAS
CAUTION
DO NOT operate vehicle in dusty or sandy areas without inspection plates or drain plugs.
Failure to comply may result in equipment damage.
NOTE
Air cleaners are to be opened and serviced only by f eld maintenance personnel.
1. Operation in dusty and sandy areas shortens service life of air cleaner. Service inspection parts, air cleaner
f lter element, and air cleaner box assembly more frequently.
2. When at halt for extended periods, cover entire vehicle with canvas. Where entire vehicle cannot be covered,
protect periscopes and other optical surfaces against scratches by wind-blown sand. Protect engine
compartment against entry of sand or dust.
3. When extended for crossing, frequently check hydraulic seals, hydraulic lines, and f ttings for leaks. Wipe
hydraulic cylinder clean after use and cap all hydraulic f ttings.
4. Keep scissoring cables clean of sand buildup.
5. Inspect tracks/sprockets often for signs of track guide and sprocket tooth wear.
6. Avoid sharp, high-speed turns in loose or f
in
e sand. Track tension is particularly important in loose or
fine
sand.
7. Additional information on operating equipment in extreme environmental conditions can be found in FM 90-3,
Desert Operations.
