EXTREME COLD WEATHER MAINTENANCE -- CONTINUED
7. Metal Parts.
Metal parts become more brittle and cannot take shock loads at arctic temperatures. Make frequent inspections
of metal areas. Remove corrosion from exterior metal surfaces with abrasive paper or cloth and apply a protective
coating of paint, oil or suitable rust preventative.
8. Plastic and Rubber Parts.
Any parts made of plastic or rubber materials must be handled carefully. These become brittle in cold weather
and may break due to vibration or handling. To prevent insulation from cracking and causing short circuits, warm
plastic or rubber insulation cables before bending and be sure all cables are secured in the vehicle.
9. Vision devices.
Do not expose vision devices to sudden changes in temperature. Equipment used outside at low temperatures
should stay outside to avoid fogging.
Do not allow weapons recoil mechanism to freeze. Severe damage to the weapon might
result if the recoil mechanism is frozen.
Keep bore of machine gun and firing mechanism covered when not in use to prevent entrance of snow.
Clean bore of the machine gun while barrel is still warm, if possible.
The recoil mechanism may stick unless it is exercised frequently. Refer to FM 23--65 or TM 9--1005--213--10
for methods of exercising.
