PREPARATION FOR COLD ENVIRONMENT OPERATIONS - Continued

CAUTION

Before operating vehicle, ensure the vehicle has been prepared for cold

weather environment in accordance with FM 9-207. Refer to FM 31-70, FM

31-71, and FM 21-305 for additional information on operation in cold

environment. Failure to comply may result in damage to equipment.

Monitor instrument panel assembly gages closely. If there are any unusual

readings, stop vehicle and shut off engine. Check for cause immediately.

Failure to comply may result in damage to equipment.

When ambient temperature rises above 25F (-32C), the vehicle must not

be operated with arctic belts installed. Notify Field Maintenance. Failure to

comply may result in damage to equipment.

Park in shelter when possible. If shelter is not available, park so vehicle does

not face into wind. Follow procedures in FM 9-207 to prevent vehicle from

freezing in place. Failure to comply may result in damage to equipment.

Install cab arctic front cover and cold weather radiator cover when outside

temperature is below 40F (4C). Both covers must remain on vehicle in

outside temperatures of -26F to 50F (-32C to 46C). Failure to comply

may result in damage to equipment.

Fuel filter should be drained before topping off fuel tank. Keep fuel tank as

full as possible during cold weather operations. Moisture will form in fuel tank

as it cools. Moisture will freeze and block fuel supply to engine. Failure to

comply may result in damage to equipment.

All snow and ice should be removed from vehicle as soon as possible. Snow

and ice may slow or prevent movement of equipment. Failure to comply may

result in damage to equipment.

NOTE

LH and RH sides of cold weather radiator cover are installed the same way.
