6. Preparing the saw system for use
Securing the wire guides and saw drive unit
■
A basic prerequisite for efficient and safe wire saw-
ing is ensuring that the equipment is securely and safe-
ly fastened in position.
■
Fastening components suitable for the material in
question must be used to secure the drive unit and for
mounting the single-pair pulley stands, release pulley
stand etc.
■
Tension rods located in through-holes, for example,
may also be used in masonry.
WARNING
Use an anchor suitable for the material on which you
are working and observe the anchor manufacturer’s
instructions.
NOTE
Hilti M12 metal expansion anchors are usually suita-
ble for fastening diamond core drilling equipment to
uncracked concrete. Under certain conditions it may
be necessary to use an alternative fastening method.
Please contact Hilti Technical Service if you have any
questions about secure fastening.

■
The clamping spindles and clamping nuts with swiv-
el baseplate recommended for use with these anchors
ensure that the equipment can be fastened in position
quickly and securely. Important: The clamping spin-
dles are wearing parts and should be replaced when
necessary. Check that they are in good condition before
use and do not straighten them by hammering.
■
Alternatively, ceiling support jacks, quick-release
columns or tension belts may be used instead of anchors
for securing the DS WS 15 drive unit.
■
Depending on the floor or ground on which the
DS WS 15 drive unit is standing, it may not always be
necessary to secure the unit. If the floor has a rough
surface, or the ground is soft, the weight of the drive
unit itself is sufficient to achieve the reaction force nec-
essary to oppose wire tension during sawing.
■
The anchors for fastening the single-pair pulley
stands do not require to be very precisely positioned.
Thanks to their adaptable clamping system, the pulley
stands and guide pulleys can always be lined up pre-
cisely with the cut. Approximate positioning is ade-
quate (see fig. 3).
■
In addition to the central clamping spindle, the lev-
elling screws on the pulley stands can also be tight-
ened. The wire guide pulleys are then fastened secure-
ly and will not work loose, even when subjected to vibra-
tion.
Connecting the electric power, water and
compressed air
Please also refer to Section 2, “Description of the saw
system”
■
Situation: The wire saw is installed, all switches at
the control unit are in the OFF or NEUTRAL positions,
the EMERGENCY STOP button is pressed in.
■
Connect the system’s own 400 V power cable and
24 V control cable between the drive and the control unit.
Important:
The control unit must be positioned outside
the hazardous area of wire saw operation!
■
Connect the socket of the 400 V mains supply cable
/ extension cable to the control unit (EURO plug, 400 V,
32 A, 5-pole).
