The distributor is controlled by means of a pedal (1) positioned
on the left side of the backhoe control lever unit. The movements
of the levers described in “3.3.6.1 (pos. 16-17) BACKHOE CON-
TROL LEVERS” remain unchanged.
The hammer is operated by pressing the pedal (1) with the toe,
since in this way pressurized oil is conveyed into the circuit;
when the pedal is released, the oil flow is interrupted and there-
fore the hammer is stopped.
If the machine is equipped with backhoe servo controls, the
hammer is operated by means of the foot-operated button (5)
positioned on the cab floor.
The movements of the levers described in “3.3.6.2 MACHINE
CONTROLS (Version with servo controls)” pos.16-17 remain un-
changed.
The hammer is operated by pressing the foot-operated button
(5), since in this way pressurized oil is conveyed into the circuit;
when the foot-operated button (5) is released, the oil flow is in-
terrupted and therefore the hammer is stopped.

•
All the movements of the boom, the arm and the equip-
ment are inhibited when the control safety device is
locked, see “3.3.6.2 MACHINE CONTROLS (Version with
servo controls)” pos. 27.
This configuration includes also the fixed installation of rigid or
flexible pipes, more precisely a delivery (2) and a discharge (3)
pipe that convey/discharge the oil necessary for the operation of
the hammer and reach the proximity of the hammer connection
(4).
