Digger Safety and
Operation
7. Follow steps 3 through 5 until the hole is to the desired depth. For increased
digging depth, the lower pin connecting the auger flighting to the Kelly bar may
be unpinned and the digger drive can be raised to extend the length of the Kelly
bar. Insert pin in the proper hole of the Kelly bar before resuming the digging
operation. Hole depths of up to 16 feet can be obtained. Be sure to retract the
Kelly bar before stowing
Stowing
The digger system is designed to stow with the auger flighting attached. If it is
necessary to stow the auger drive without the flighting, care should be taken when
rotating the Kelly bar into the stow bracket because the over wind valve may not match
up with the Kelly bar. The over wind valve is an operator’s aid only, and may not
stop the auger from turning completely. Care should always be taken when
stowing the auger.
1. Clean the flighting before stowing to maintain a longer life, and to reduce
excessive strain on the stow bracket due to additional weight. This will also
prevent dirt from falling off the flighting during the stowing procedure or when
transporting the crane
2. Retract the boom completely before starting the stow procedure
3. Attach wind-up rope to the upper end of the auger flighting and clear all
personnel from the work area
4. Operate the AUGER ROTATION lever in the CCW (or Reverse) direction to start
wrapping the wind-up rope on the auger flighting shaft. Stow only in the CCW
direction as indicated on the DEPLOY AND STOW PROCEDURE decal located
at the operator’s station. Raise the boom to approximately 45 degrees, as lesser
boom angles may cause the rope to wind improperly on the auger flighting shaft.
While raising the auger to stow, hold the AUGER LATCH lever in the OPEN
position. Once the auger flighting shaft rises into the pocket of the stow bracket
and is contacting the over-wind valve, move the AUGER LATCH lever into the
OPEN position. Once the auger flighting shaft raises into the pocket of the stow
