Pulling the wire through, rigging and connect-
ing the wire
When feeding the wire through by hand, ensure that the
marks on the wire indicating correct running direction
correspond to the direction of rotation arrow on the dri-
ve unit. Seen from the front of the machine, the drive
wheel rotates in a counter clockwise direction.
Should the running direction indicator marks on the wire
no longer be visible, the direction of travel can be deter-
mined from the shape of the diamond beads as they have
a slightly conical form when worn (narrow end ahead).
First feed the wire through the object to be cut and then
round off the corners at the rear of the object by pulling
the wire back and forward manually, in a sawing motion,
until the wire can be moved freely by hand.
7.9
Feed the wire through the hollow axles of the pulley
stands (if used) and subsequently through the hollow
axles on the pulley crossbar on the compact wire saw.
To ensure that the sawing wire wears evenly and stays
round, we recommend that the wire is twisted in a coun-
terclockwise direction (approx. half a turn per meter
length) before the ends are connected together.
Lay the sawing wire over the return pulleys and drive
pulley and then tension it slightly by moving the drive
unit along the guide rail (piston rod clamp).
