6. Preparing the saw system for use
■ Move the drive motor on the carriage manually into
the desired position. Before this can be done, the two
compressed air connections located at the rear of the
drive must be connected, or coupled together (so that
the air in the pressure cylinders can circulate).
■ Ideally, the drive should be rigged with only the basic
minimum length of wire (at least 3.2 m) at the com-
mencement of sawing. This allows the maximum thick-
ness to be sawn through without having to adjust or
change the wire. Nevertheless, it is possible to begin saw-
ing with the wire storage pulleys occupied to full capacity.
■ The operator at the control unit should set the advance
pressure to approximately 1 bar by adjusting the pres-
sure control and then tension the wire by moving the
advance lever (fig. ). At the same time, the operator
at the drive unit should ensure that the wire is lying cor-
rectly on the storage pulleys (fig. ).

nected with the pin provided. The vice mounted on the
front of the drive unit is designed to hold the wire secure-
ly and thus makes this operation easier. Twisting the wire
ensures that the wire wears evenly.
■ Starting from the upper guide pulley (hollow axle)
located at the slack side, pass the connected wire around
the 280 mm diameter drive wheels (refer to the sticker
on drive unit) and fix the lower guide pulley on the ten-
sion side in the corresponding storage position. Pass
the wire around the storage pulleys in one or more turns,
as necessary. When doing so, it may be necessary to re-
position the entire drive unit by moving it forward or
back before fastening it in position..
