ARRANGEMENT FOR THE OPERATION OF OPTIONAL EQUIPMENT
6.3.2 CONTROL PEDAL (2)
This pedal controls the delivery and return of the oil to the op-
tional equipment.
1 - If the pedal is pressed in (A), high-pressure oil is conveyed to
the equipment through the left piping (3).
2 - If the pedal is pressed in (B) with the selection valve (1) con-
trol in (B), high-pressure oil is conveyed to the equipment
through the right piping (4).
3 - If the circuit is arranged for the use of equipment with unidi-
rectional flow (demolition hammer, etc.) and therefore with
the selection valve (1) control in pos. (A), press the pedal (2)
in (A) only, since the right piping (4) serves exclusively for the
return of the oil to the tank.
