Use Of The Electro-Hydraulic System For Machine Positioning (Optional) - IRTEC G 4 Manual D’instruccion De Utilizo Y Manutencion

9.0 USE OF THE DISCHARGE VALVE (optional)
If the machine is equipped with a discharge valve, before starting operation proceed as follows:
1) Take off the plug on the outlet connector of the valve
2) Set the machine in operation;
3) Check that at the end of the stroke, the valve is opened by the 3 way valve which drives it.
To check if the 3-way valve opens the discharge valve:
1) Push the manual disengaging rod manually and simulate the end of the working phase;
2) If the valve does not open, adjust the stroke of the control valve lever using the adjusting screw (fig.37).
ATTENTION: when the discharge valve is opened water comes out suddenly and violently. Do not stay near the outlet
pipe.
DANGER!!: If the machine is located near a road or a work site, make sure that the water coming out from the discharge
valve cannot reach persons or transit places. To avoid this danger, it is necessary to connect a pipe to the outlet connector of
the discharge valve to discharge the water on the ground without danger
10.0 USE OF THE ELECTRO-HYDRAULIC SYSTEM FOR THE MACHINE POSITIONING
(Optional)
If the machine is equipped with electro-hydraulic system to operate the electric engine,
proceed as follows:
1) Put the proper switch in position 1 (fig.33)
2) Position the machine operating the levers of the hydraulic distributor.
3) At the end of the positioning procedure, put the switch to the stop (fig.33 position 0)
4) While the machine is working, put the switch (fig.33) in position2. In this position
the alternator connected to the gearbox starts to recharge the battery and the red warn-
ing light placed on the control panel must be off. If the warning spy is on while the
switch is in position 2, the alternator is not charging the battery. Select a slower gear in
the gearbox in order to increase the rotation speed of the turbine.
If the machine is equipped with remote control, proceed as follows:
1) Select the remote control by pressing the convenient button. (fig.34).
2) Position the machine operating the buttons of the push-button panel. (fig. 35)
3) At the end of the positioning put the switch as in picture (fig.33) in position 2
(battery recharge)
4) When the machine is not working, put the switch fig.33 in the idle position 0. In
case of breakdown of the remote control it is possible to operate manually the hydrau-
lic system by following these operations:
a: Connect the electric engine to the operating button with the free electric cable placed
near the engine. (fig.36)
b: Put the electric switch fig.33 in position 1 (work)
c: Operate manually the control device of the electro valves by pushing the button of
the pitonslot valve (fig.37) and alternatively the different but of the electro valve to
operate the machine (fig.38).
