OPERATING THE DRILLING RIG

12.
The tool is removed from the hole by commanding the upward
movement (joystick
A
back). The operation consists in two phases:
during the first phase, stop when the auger protrudes about 1 m from
the ground; in this phase the rotary is lowered (the tool remains still due
to friction with the ground) to be hooked to the base of the extension
rod (inverse operation than point 9); when the rod is hooked, the tool is
extracted and tools are used to remove earth from the auger.

The last part of the auger is extracted, lifting the entire mast and
therefore re-enabling the joystick
A
with the selector
E1
.

Do not rotate the tool to discharge earth.
