standing securely. For safety reasons, the wheel assem-
bly must not be used when working from scaffolding
or similar platforms.
Care and maintenance
Care
The housing, container and cover are made of impact-
resistant plastic. The protective sleeve of the cable and
the hoses are made of an elastomer material. The out-
er sheath of the hose set consists of a hard-wearing
woven synthetic material.
Clean the parts of the unit regularly with a
damp cloth. Do not use spray equipment, a
steam cleaning system or running water for cleaning.
This may negatively affect the electrical safety of the unit.
Always keep the grip sections of the unit free of oil and
grease. Do not use cleaning agents which contain sili-
cone. Do not allow foreign objects to enter the interior
of the unit.
Regenerate the main filter and clean the container at
regular intervals, particularly before each long pause
between periods of use (e.g. at the end of the work-
ing day). Check the entire diamond drilling system for
leakage before each period of operation. Check and
clean the seals at regular intervals. Never leave drilling
slurry or water in the container for long periods.
Maintenance
Check all functional components and operating
controls of the unit for damage and correct oper-
ation at regular intervals. Do not operate the unit if parts
of it are damaged or when the operating controls do not
operate faultlessly. The unit should be repaired at a Hilti
service centre if necessary.

Manufacturer's warranty – tools
Hilti warrants that the tool supplied is free of defects
in material and workmanship. This warranty is valid so
long as the tool is operated and handled correctly,
cleaned and serviced properly and in accordance with
the Hilti Operating Instructions, and the technical sys-
tem is maintained. This means that only original Hilti
consumables, components and spare parts may be
used in the tool.
This warranty provides the free-of-charge repair or
replacement of defective parts only over the entire lifes-
pan of the tool. Parts requiring repair or replacement
as a result of normal wear and tear are not covered by
this warranty.
Additional claims are excluded, unless stringent
national rules prohibit such exclusion. In particular,
Hilti is not obligated for direct, indirect, incidental
or consequential damages, losses or expenses in
connection with, or by reason of, the use of, or inabil-
ity to use the tool for any purpose. Implied warranties
of merchantability or fitness for a particular purpose
are specifically excluded.
For repair or replacement, send tool or related parts
immediately upon discovery of the defect to the address
of the local Hilti marketing organization provided.
This constitutes Hilti's entire obligation with regard to
warranty and supersedes all prior or contemporane-
ous comments and oral or written agreements con-
cerning warranties.
