SECTION IV. OPERATION UNDER UNUSUAL CONDITIONS
2-12. OPERATION IN EXTREME COLD (BELOW 10 [-12.2 ]).
a. A thermostatically controlled fuel heater mounted in the carburetor heats the fuel when the temperature drops
below 40 60F (4.4 + 3.30C). This preheating of fuel aids combustion and ignition during extremely cold weather.
Take the following steps during extremely cold conditions:
(1) Keep the fuel tank full to prevent condensation of moisture in the tank.
(2) Clean snow and ice from fuel tank filter to keep fuel lines from freezing.
2-13. OPERATION AT HIGH ALTITUDES.
a. The heater will operate at elevations up to 10,000) feet above sea level without special service or adjustment.
b. At 10,000-foot altitude, heat output may be reduced by approximately 15 percent.
2-14. OPERATION UNDER RAINY/HUMID CONDITIONS.
a. Wipe all accessible exposed areas frequently.
b. Paint all chipped or scratched surfaces to prevent rust.
Cover the heater when not in use.
2-15. INTERIM NUCLIEAR, BIOLOGICAL, AND CHEMICAL (NBC) DECONTAMINATION PROCEDURES.
Detailed decontamination procedures can be found in: FM 3-3, FM 3-4, and FM 3-5.
a. General. The following emergency procedures can be performed until field NBC decontamination facilities are
b. Emergency Procedures. If NBC attack is known or suspected, mask at once and continue mission. Do not
unmask until told to do so.
(1) Nuclear decontamination. Brush fallout from skin, clothing, and equipment with available brushes, rags, and
tree branches. Wash skin and have radiation check made as soon as tactical situation permits.
(2) Biological decontamination. Remain masked and continue mission until told to unmask.
(3) Chemical detection and decontamination.
Do not use decontamination spray on personnel. It could cause personal injury.
Determine if liquid agent is present on the surface of the equipment.
