Pos.3: Plunge movement (right / left). As the control hoses necessary for this function may not be connected to
the wall saw when used for wire sawing, this rotary switch has no function.

10.3 Remote control unit: starting and operating the saw system
1.
Adjust the current (6) to a value between 32
amps
and approx. 50
amps
depending on the mains supply avail-
able on the jobsite.
2.
Switch on the water supply.
3.
Knobs (3), (4), (5) and (7) should be set to the «0» (neutral position). Switch on the electric motor (1) and check
that the hydraulic unit switches from star to delta (takes approx. 2–5 seconds).
4.
Use the longitudinal advance control (4) to select the correct direction of movement for wire tension and use the
advance speed control (5) to tension the diamond wire slightly.
5.
Use the potentiometer (2) to start the drive wheel motor slowly and, at the same time, adjust the advance speed
control knob (5) in order to maintain or increase tension on the diamond wire.
As soon as the diamond wire is running correctly, the speed of the drive wheel can be increased to maximum,
by adjusting the potentiometer (2). This corresponds to a speed of 800 r.p.m. The cutting speed of the diamond
wire is then 20 m / sec.
Subsequently, only the advance speed control (5) requires adjustment in order to control the diamond wire ten-
sion and, thus, the sawing performance. A visible indication of correct tension is given by the wire tensioning arm,
which should rise approx. 10 to 15 cm.
The saw should be operated at a pressure of approx. 120 bar (max. 140 bar) in the main hydraulic circuit in order
to achieve optimum sawing performance without excessive strain on the diamond wire.
