TM 5-2590-512-13&P SECTION IV. OPERATION UNDER UNUSUAL CONDITIONS 2-14. Cold Weather Conditions. a. Follow procedures in Section III, Operation Under Usual Conditions, and observe the following precautions. CAUTION Do not move Auger rotation lever from mid-position to full forward or rearward position because this will force hot hydraulic fluid into cold Auger Drive Unit and could damage internal parts. To ensure components warm up slowly move Auger rotation lever slowly and intermittently back and forth, for at least five minutes. In frost or frozen ground, operator must check condition of Auger, center point, and teeth after every hole is dug. See operator PMCS Table in para. 2-7. NOTE Rotate Auger clockwise when digging. After hole depth is reached, stop auger rotation, then hoist Auger out of hole. Auger must not rotate when hoisting out of hole or dirt will be deposited back into hole. b. Move Auger rotation control lever back and forth slowly and intermittently, for at least five minutes, to ensure components in Auger Drive Unit are warmed up slowly. c. Lower Earth Auger Assembly until Auger is just touching frozen ground. d. Begin digging hole. 2-18
