OPERATION UNDER UNUSUAL CONDITIONS - CONTINUED
OPERATE IN EXTREME HEAT - CONTINUED
Lubricate according to WP 0012 00, Preventive Maintenance Checks and Services (PMCS) Introduction, with the tem-
perature range that applies to the highest expected temperature.
Check and clean air precleaner at closer than normal intervals.
Check air cleaner indicator frequently. Notify Unit Maintenance if the red indicator locks in the visible position.
Park machine under cover, if possible. Cover windshield (if equipped) to protect against sand blasting.
Ensure all tires are inflated to proper pressure.
Check frequently for rust. Clean and lubricate machine to help prevent deterioration.
OPERATE IN MUD OR SOFT SURFACES
Before entering mud or other soft surfaces, check conditions and engage differential lock. Select appropriate transmis-
sion gear range. Enter soft area at a medium speed for gear range selected.
Maintain steady pressure on accelerator pedal to keep machine rolling until solid ground is reached. Do not accelerate to
point where wheels spin, if possible.
If machine gets stuck, try to pull out slowly in a low gear. Boards, brush, or similar materials may be placed under tires
to provide traction.
Notify Unit Maintenance to clean and inspect for proper lubrication.
OPERATE IN SANDY OR DUSTY CONDITIONS
Maintain steady, even movement with transmission in lower gears. Use differential lock as required. Try to keep
machine rolling without straining engine and powertrain. If machine gets stuck, notify Unit Maintenance.
Whenever operating in sandy or dusty areas, you should:
Service engine air cleaner more frequently.
Make sure each tire has a valve cap.
If machine overheats, stop and perform troubleshooting procedures.
Make sure 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 fluid filler locations before checking or adding
Clean spouts of fuel containers and areas around filler caps on fuel tanks before adding fuel. Under extremely
sandy or dusty conditions, filter fuel when filling tanks.
Cover windshield (if equipped) to protect against sand blasting.
Notify Unit Maintenance to clean, inspect, and lubricate more frequently.
When operating the machine on soft sand at slow speeds, the tire inflation pressure may be decreased for improved
traction. Refer to FM 21-305.
Check hydraulic cylinders, top of circle, centershift linkage, and articulation cylinders frequently. Do not allow
dust, dirt, or sand to collect in these areas.
