10. 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,
running water for cleaning. This may negatively affect
the electrical safety of the power tool. Always keep the
grip surfaces of the power tool free from oil and grease.
Do not use cleaning agents which contain silicone.
8.3 Maintenance
Check all external parts of the power tool for damage at
regular intervals and check that all controls operate fault-
lessly. Do not operate the power tool if parts are dam-
aged or when the controls do not function faultlessly. If
necessary, your power tool should be repaired at a Hilti
repair center.
Repairs to the electrical section of the power tool may
be carried out only by trained electrical specialists.

After carrying out care and maintenance, check the power
tool for correct operation (drive and remove a screw).
