OPERATION ON UNUSUAL TERRAIN
General
It is difficult to cover all adverse conditions you will encounter when driving over unusual terrain In this manual. Therefore,
It is essential you review and become familiar with the procedures In FM 21-305. Use these procedures along with the
following guidelines when operating the M876 Truck on ice, snow, mud and off
the road.
Operational Guidelines
1.
Operation on snow, Ice covered terrain or In deep mud requires the use of tire chains on the rear driving
wheels.
CAUTION
Do not lower tire pressure so low that tire damage can occur.
2.
Lowering tire pressure, In cases of sand, ice, mud and snow will help increase tire traction, if tire chains are
not available. Tire pressure reduction (deflation) should not be more than 35 to 45 psi (241 to 310 kg)
maximum. See page 2-40 for correct tire pressure.
3.
Use the front winch to recover the M876 truck if hopelessly mired in deep mud or snow, and not movable by
wheel traction. See FM 20-22 Vehicle Recovery Operations, and Towing the M876 Truck, in this manual, or
see FM 21-305.
4.
Use the power lock divider in areas where the ground surface provides poor traction. Move control lever to
the IN position for dual axle operation, and to the OUT position when conditions are normal. See page 2-80
for Instructions.
