UNUSUAL TERRAIN OPERATION
INITIAL SETUP:
Personnel Required
Crewman (3)
References
Chocking vehicle (WP 0103)
References (cont.)
Main engine air cleaner maintenance (WP 0119)
Transmission shift selection (WP 0012)
MUD
Use 1st gear when driving through mud to prevent digging in. Go up and down grades as straight as possible and
avoid sharp turns. In cold weather operation, park on high, dry ground, on planks, or on brush. Chock vehicle
(WP 0103), if necessary. This will keep the tracks from freezing to the ground. Clean the tracks and wheels of
mud before it freezes.
SNOW
The M88 can drive over heavily crusted snow. If vehicle breaks through the crust, shift to 1st gear (WP 0012) and
drive slowly to get back on top. Go up and down grades as straight as possible and avoid sharp turns. When
snow is soft or fine, drive cautiously.
ICE
Drive carefully and steadily on ice. If vehicle starts to skid, let off the accelerator. Move out slowly.
SAND AND DUST
Be careful not to spin the tracks. If track spinning occurs, slow down and use the proper gear to move steadily. Do
not let the engine labor for too long. The engine may overheat. When traveling in soft sand, do not make sharp
turns in 1st gear. The tracks will be thrown because of sand building up in the suspension system. Wide turns
should be made in 2nd or 3rd gear. Monitor air cleaner restriction indicator gauge, located above air cleaners, for
clogging conditions. Clean filters (WP 0119), if necessary.
STEEP SLOPES
In an emergency when going forward down a very steep slope, 50 to 60 percent, brake vehicle by shifting to R on
slope of hill. Apply brakes before shifting into or out of R. When you go down, speed up engine to increase
braking and to keep engine from stalling.
