OPERATION GUIDELINES
CHANGING AUGERS
1. DO NOT change or remove an auger directly underneath a power line.
2. Lower the outriggers. Make sure the vehicle is stable for boom movements.
3. If the changeover auger is stored on the bed of the vehicle, it must be removed to ground level. Use a
sling and the winch for removing auger.
4. When the changeover digger/auger is on the ground, remove the sling and winch line.
5. See lowering procedure.
6. There are two choices of what to do once the auger is un-stored.
a.If you are in an area where you can digger the auger into the ground, dig down about two feet and
stop. Remove the auger retaining nut and bolt. Raise boom so the hex shaft is clear of the auger. Use
the winch line and a sling to pick up the changeover auger. Attach the sling to the auger above the
balance point. Raise auger until it is in an upright position. Guide the auger underneath the hex shaft.
Lower hex shaft into auger stem. Install the retaining bolt and nut in the desired hex shaft extension
hole. Remove sling.
b.To handle auger(s) when you cannot dig in, wrap a sling around the auger stem above the balance
point. Attach winch line and raise the auger slightly so the retaining nut and bolt can be removed.
Raise the boom and pay out the winch line. When the hex shaft clears the auger stem, lower auger to
the ground. Use the winch line and a sling to pick up the changeover auger. Attach the sling to the
auger above the balance point. Raise auger until it is in an upright position, leaving the auger head on
the ground. With assistance from ground personnel, align the hex shaft with the auger stem. Lower
hex shaft into auger stem. Install the retaining bolt and nuts in the desired hex shaft extension hole.
Remove sling.
Wrap a sling around the auger above the balance point. DO NOT wrap the winch
line around the auger as the sharp flights could damage the winch line.
