Section IV. OPERATION OF MATERIEL USED IN CON-
JUNCTION WITH AIR COMPRESSOR
32. Vehicle Operation
The 210G1 compressor is mounted on the M45 truck. Refer to TM 9-819 for proper truck operating instructions.
33. Fire Extinguisher
a. Description.. The fire extinguisher is a one-quart, carbon tetrachloride type. The fire extinguisher is installed in a
bracket mounted at the rear of the compressor housing.
b. Operation. To operate the fire extinguisher, turn the handle and work like a pump. For structural fires, direct the
stream of carbon tetrachloride at the base of the flames. For burning liquids, direct the stream of carbon tetrachloride
against the inside of the container above the surface of the liquid.
Warning: Extinguish fire promptly and avoid exposure to smoke and fumes.
c. Refilling. Refill the fire extinguisher as instructed in TM 5-687 and TM 9-1799.
Section V. OPERATION UNDER UNUSUAL CONDITIONS
34. Operation in Extreme Cold (Below 0 F.)
a. Cooling System Protection. The radiator should be filled with six parts of antifreeze solution and four parts of
water for winter and summer operation. Coolant must be maintained at proper level to prevent loss from expansion
between upper and lower step of baffle in radiator top tank. Check the entire cooling system periodically for leaks and
hose deterioration.
b. Special Lubrication Instructions. Select the correct lubricants in accordance with the expected air temperatures as
indicated in the lubrication order (fig. 16).
c. Fuel System Protection. In cold weather, condensation of moisture in the air causes water to accumulate in
gasoline tanks, drums, and containers. This water will freeze and form ice crystals that clog fuel lines and carburetor jets
unless the following precautions are taken:
(1) Use filter paper or other type of strainer when filling fuel tank or when transferring fuel from one container to
another.
(2) Remove snow or ice from fuel tank fillercap and filling equipment before filling the fuel tank.
(3) Keep fillercaps tightened securely to keep snow, rain, and dirt out of tanks.
