Refer to FM 9-207, Operation and Maintenance of Ordnance Materiel in Cold Weather
and ATTP 3-97.11, Cold Region Operations for additional information on cold weather
operation and maintenance.
Extreme cold causes many problems:
1. Lubricants thicken or congeal.
2. Batteries may freeze or lose their electrical efficiency.
3. Electrical insulation may crack and cause short circuits.
4. Fuel may not readily atomize for combustion.
5. Water separator in fuel filter may freeze if not drained.
6. Various materials will become hard, brittle, and easily damaged.
7. The cooling system requires adequate protection from extreme cold.
8. Fuels, lubricants, and antifreeze compounds require special storage, handling, and use.
9. Any water in the fuel water separator may freeze if not drained.
10. Tracks may be frozen to ground.
Cooling System
0006
1. Inspect for leaks and general condition.
2. Ensure clamps are tight.
3. Check cooling system fluid level in fluid reservoir.
4. Notify Field Maintenance if system needs service.
Fuel Tank
0006
1. DO NOT allow fuel tank to remain partially empty for a long period of time in extremely cold weather.
2. Fill after each work period to help avoid water condensation in the fuel tank.
3. Remove all ice and snow from around the fuel filler opening before refueling.
Electrical System
0006
1. Inspect battery cables, wiring harness, and wiring.
2. Check for breaks or cracks caused by cold weather. Report any problems found to Field Maintenance.
3. Save the batteries. Use lights and other electrical equipment as little as possible.
Lubrication
0006
Lubricate according to Lubrication Order 5-2410-240-13 with the temperature range that applies to the lowest
expected temperature.
