3.1 Make sure sufficient space is available for working safely. If possible, the wire saw should be set up on the floor
in an upright position.
3.2 Check the entire system, accessories, power unit, electric cables, hydraulic hoses and accessories for damage and
proper functioning before use. Wearing parts, accessories and safety-relevant devices, such as the diamond wire
drive wheel, return pulleys, diamond wire and couplings, diamond wire guard and drive wheel guard, end stop,
drive wheel mounting screw, hydraulic couplings, etc., must be checked particularly carefully. Check that all parts
have been assembled correctly and consider all other factors that could influence operation of the equipment.
Contact your Hilti representative or Hilti service centre if faults or deficiencies are found. Repairs to electrical parts
must be carried out by a qualified electrical specialist.
3.3 Metal anchors of M12 size should be used for fastening the DS-WSRF rail support and DS-WSSPP single-pair pul-
ley stand. The fastening used must be suitable for the base material in question and must not work loose. Suitable
Hilti anchors are, e.g. HKD-D, HSA-A, HIT or HEA. If masonry is loose or crumbling, we recommend that through
holes are drilled and M16 threaded rods with clamping nuts used for fastening.
3.4 Fastening screws of at least 8.8 grade as per ISO should be used for the rail supports or, alternatively, use the
DD-CS M12 S-SM clamping spindle with DD-CN-SML quick-release clamping nut.
3.5 An end stop must always be fitted at the end of the rail to prevent unintentional advance beyond this point (pre-
vents the saw head coming off the end of the rail).
3.6 It is essential that the specified checks are carried out before sawing.
3.7 The drive wheel guard (see fig. 3.7, no. 1) and diamond wire guard (see fig. 3.7, no. 2) MUST ALWAYS BE FITTED
when the saw is in use. These guards prevent parts flying out in the direction of tension should the diamond wire
break. NEVER stand in a position in line with the diamond wire while the saw is running.

Safety measures must be implemented in the area where sawing is taking place so that operators and
bystanders cannot be injured or property damaged by a broken sawing wire or debris that may fly off
during the sawing operation (wire connectors, diamond beads, spacing springs, small stones, saw-
ing slurry, etc.). Safety measures must also be implemented in the area not directly visible to the oper-
ator, i.e. behind where sawing is taking place.
