b.
Check cooling system, air cleaner restriction indicator, and engine oil level frequently. Be sure that radiator is free of
bugs, dust, and other foreign matter. Perform necessary services and notify Unit Maintenance of any unusual gauge
readings or problems.
c.
Notify Unit Maintenance to shorten rear axle differential oil change interval from interval designated in Unit PMCS.
3.
Parking Vehicle.
a.
Park vehicle under cover or in the shade, if possible.
b.
Ensure all tires are inflated to proper pressure.
c.
Clean and lubricate vehicle with correct grade of lubricants to help prevent deterioration. Have Unit Maintenance
change filter elements at shorter than normal intervals, as designated in Unit PMCS.
OPERATE IN MUD OR SOFT SURFACES
1.
Before entering mud or other soft surfaces, check conditions, stop vehicle, and select appropriate transmission gear range.
Enter soft area at a medium speed for gear range selected.
2.
Maintain steady pressure on accelerator pedal to keep vehicle rolling until solid ground is reached. Do not accelerate to
point where wheels spin and do not stop, if possible.
3.
If vehicle gets stuck, try to pull out slowly in a low gear. Boards, brush, or similar materials may be placed under tires to
provide traction.
4.
Notify Unit Maintenance to clean and inspect propshaft for proper lubrication.
OPERATE IN SANDY OR DUSTY CONDITIONS
1.
Maintain steady, even movement with transmission in lower gears. Try to keep vehicle rolling without straining engine
and powertrain.
2.
If vehicle bogs down, place boards, brush, canvas or similar materials under and in front of tires after shoveling a clear
path ahead of each tire. This should improve traction.
3.
If these efforts fail and it becomes evident that vehicle will not free itself, have another vehicle tow stuck vehicle (Refer to
Towing Tractor in this work package).
4.
Whenever operating in sandy or dusty areas, you should:
a.
Ensure each tire has a valve cap.
b.
Check engine coolant temperature and engine oil pressure frequently.
CAUTION
Limit unnecessary idling time to five minutes. Under no condition should idling time exceed a maximum of
10 minutes. Excessive idling can cause carbon buildup and damage to engine.
c.
If vehicle overheats, allow engine to idle. If engine does not cool sufficiently after a maximum of 10 minutes, shut
down and notify Unit Maintenance.
d.
Ensure engine oil filler tube and transmission fluid filler tube are cleaned before dipsticks are removed to check fluid
levels. Clean accumulations of sand and dirt from around any fluid filler locations before checking or adding fluids.
e.
Clean spouts of fuel containers and areas around filler caps on fuel tank before adding fuel. Under extremely sandy or
dusty conditions, filter fuel when filling tank.
f.
Cover window glass to protect against sand blasting.
g.
Notify Unit Maintenance to clean, inspect, and lubricate drive shaft more frequently.
