To extract the pile proceed as outlined below.
1) Start the machine (see “Starting the engine”).
2) Move the levers (W) to shift the machine to the pile driving point.
3) Place the column in a perfectly vertical position.
- To manually position the column in vertical position use the levers (F) and (G).
- Check the verticality using the level gauge (S).
- To automatically place the column in vertical position see “Using the verticality sys-
tem”.
- Move the lever (T) and the lever (U) to position the percussion hammer right on the
driving point.
4) Move the lever (H) and lower the jack (L) to the ground to counter the force applied for
the extraction.
Caution - Care
On loose ground place a plate (M) of a suitable size between the ground and the foot
of the outrigger to increase the resting surface area.
The outrigger foot must rest on the ground applying a light pressure but not lifting
the machine.
5) Move the lever (N) to lower the percussion hammer until the clamp is positioned on
the end of the hammer.
6) Lock the grip of the clamp on the pile using the lever (P).
7) Move the lever (N) (position “N2”) to slowly lift the percussion hammer until the clamp
is tensioned.
8) When the clamp is tensioned move the lever (Q) to position (Q1) and then move the
lever (N) to position (N2).
9) Move the lever (Q) to position (Q0) to stop the percussion when the pile has been
extracted from the ground and move the lever (N) to stop the lifting of the percussion
hammer.
10) Tilt the pile and move lever (N) to activate the lowering of the hammer until the pile is
on the ground.
11) Move the lever (P) to open the jaws of the clamp and remove the pile.
12) Move the lever (H) to lift the jack (L) from the ground.
13) Remove the clamp at the end of the pile extraction work.
