8. Care and maintenance
Wearing parts
■ A list of the most important consumables and wear-
ing parts is provided in Section 3 and in the tools / acces-
sories brochure. Certain parts such as guide pulleys, dri-
ve wheels and water supply nozzles can also be found
in the brochure. Please contact your Hilti representative
if you require parts.
Service and repair
■ Malfunctions are unlikely to occur as long as the equip-
ment is kept clean and well lubricated. Dirty parts and
incorrect operation lead to malfunctions.
■ The mechanical design of the wire saw system has
been kept very simple. With the aid of the consumables
items and wearing parts supplied by Hilti, the operator
is in a position to maintain and service the mechanical
parts of the system himself by replacing items such as
guide pulleys or connectors etc.
■ Other parts (spare parts) are available as necessary
from the service department and can usually be fitted
on-site by the operator himself or by a Hilti diamond sys-
tems specialist or Hilti mechanic.
■ It may happen, for various reasons, that one of the
fuses in the control unit blows.
■ All fuses are available commercially and a spare set
of fuses is provided inside the control unit. The fuses in
the control unit can be replaced by the operator. Please
refer to the “Accessories” and “Fault Finding” sections.
■ Repairs or adjustments to electrical components (e.g.
to the current converter) may be carried out only by
appropriately trained and qualified specialists. Instruc-
tions applicable to the current converter are provided
inside the control unit.
