OPERATING IN DUSTY OR SANDY AREAS (Contd)
Stopping or Parking.
Park vehicle in a sheltered area, out of blowing dust or sand whenever possible. If sheltered area is not
available, park so vehicle does not face into wind and cover vehicle with tarpaulins. When entire vehicle cannot be
covered, protect windows, cab, and engine compartment with tarpaulins to prevent entry of sand or dust.
Use low air pressure to remove all sand from vehicle engine compartment, areas around brakes, drums, and
spring seats after daily operation.
Use caution while refueling to prevent dust or sand from entering fuel tank(s). Tighten filler cap securely after
OPERATING UNDER RAINY OR HUMID CONDITIONS
Vehicles inactive for long periods in hot, humid weather can rust rapidly. Fungus may grow in the fuel tank(s),
on canvas tarpaulin, seats, and other components. Frequent inspection, cleaning (para. 2-8), and lubrication are
necessary to maintain the readiness of vehicles.
Drain off any accumulated water in fuel filter/water separator (1). To drain water from fuel system:
On M939/A1 series vehicles, open drainvalves (2) and (3) on fuel filter/water separator (1), drain water
into suitable container, close drainvalves (2) and (3) when clean fuel is visible.
