11. 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.
