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.
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.
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.
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.
Lower Earth Auger Assembly until Auger is just touching frozen ground.
Begin digging hole.
