Digger Safety/Operation EEC-0109 V1.2
Digger Safety and
Operation
8. Slowly operate the AUGER ROTATION lever in the CCW direction until the
auger shaft raises itself up from the stow latch and contacts the over wind valve.
While holding the auger in this position, operate the AUGER LATCH lever in the
OPEN direction and hold until the auger latch is fully open Do not continue
rotating the auger if contact with the over wind valve does not stop
rotation. Damage may occur to the wind-up rope or stow bracket which
could cause the auger to drop
9. Operate the auger rotation lever in the CW direction until the auger is un-stowed
and hanging vertical, and the wind-up rope is slack. Disconnect the wind-up rope
from the auger flighting
Digging
1. The boom should be extended a few feet before commencing digging operations
so that as the auger digs, the boom can be retracted or extended to maintain a
vertical hole
2. Start rotating the auger in the CW direction and slowly lower the boom until the
auger comes in contact with the ground
3. Apply slight BOOM DOWN force with the boom level while digging to keep the
auger penetrating into the ground and to follow the auger with the boom so as
not to structurally overload the boom
4. Depending on soil conditions, care should be exercised when digging so that the
auger does not screw itself into the ground (corkscrew), and cause a machine
overload
5. When the auger flighting is filled with soil, pull the auger form the hole using the
BOOM UP level and deposit the soil in the desired location. Soil can be removed
from the auger flighting by carefully switching directions of the auger. Do not
slam the auger level back and forth aggressively, or damage can result to
the operator lever, lever to valve linkage, or the digger drive assembly
6. Replace the auger into the hole and extend or retract the boom as necessary to
maintain a vertical hole
