This  section  contains  instructions  for  safely  operating  the  M1022A1  Dolly  Set  under  unusual  conditions. In  addition  to  normal  preventive  maintenance,  special  care  must  be  taken  to  keep  the  dolly  set  operational  in  extreme temperatures  and  other  environmental  conditions. b.  Refer  to  FM  21-305  and  FM  55-30  for  information  on  special  driving  instructions  under  unusual conditions. 2-24.  OPERATION  IN  EXTREME  COLD  OR  SNOW. a. Special  care  must  be  taken  when  operating  the  dolly  set  In  cold  weather.  Refer  to  FM  9-207  for  operation and  maintenance  of  ordnance  materiel  in  cold  weather.  Also  refer  to  FM  21-305  for  special  instructions  on  operating  In snow. b. Care  must  be  taken  when  placing  the  dolly  set  in  motion  after  shutdown.  Thickened  lubricants  may cause  failure  of  components. c. Refer to Chapter 3, Section I for proper lubrication during extreme cold weather. d. Care must be taken when handling electrical cables. Extreme cold weather can cause Insulation material on electrical wire to crack, causing short circuits. Components may become hard or brittle and easily damaged  or  broken. e. When  parking  for  any  period  of  time  in  temperatures  below  O°F  (-18°C),  park  in  a  sheltered  area  out  of the wind and clean off any buildup of ice or snow. Place footing of planks or brush under tires to prevent them from freezing to the ground. Ensure that tires are properly inflated (see paragraph 1-15). Underinflated tires will freeze, resulting  in  flat  spots. 2-143
