OPERATION ON UNUSUAL TERRAIN - CONTINUED
Sand or Dusty Areas
1.
The main objective when driving In sand is to maintain movement with the least amount of strain on the M876
truck engine and power train, without bogging down.
2.
This can be accomplished by looking conditions over before driving Into the sand area, and determine:
a.
Which transmission gear range to best select.
b.
What truck speed would best maintain momentum.
c.
Whether or not to deflate tires or use boards, matting, or canvas ahead of the tires.
3.
When starting out:
a.
Accelerate gradually to avoid spinning the rear wheels.
b.
Once truck is rolling, maintain a steady, even speed.
c.
Avoid shifting gears. Keep it in low gear range.
d.
Bypass difficult areas by trying to go around them.
e.
Always make wide turns. Sharp turns can stall the truck, or cause it to turn over.
f.
When stopping, allow the truck to roll to a halt, or apply brakes gradually to avoid tires digging in.
g.
Try to stop on downhill side of slopes to give truck the advantage when starting to move again.
4.
When bogged down, have another vehicle pull truck out, or use truck winch power to pull truck out, should
the tire deflation method not be successful in getting the truck out. Always remember to replace the tire valve
stem caps when deflating and inflating tires.
5.
When operating in dusty areas, always:
a.
Check engine oil pressure and engine coolant temperature frequently while driving.
