10 Disposal
Most of the materials from which Hilti tools or appliances are manufactured can be recycled. The materials must
be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements for
taking back old tools and appliances for recycling. Ask Hilti customer service or your Hilti representative for further
information.
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 system is main-
tained. 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 re-
placement of defective parts only over the entire lifespan
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 na-
tional regulations prohibit such exclusion. In particu-
lar, 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 the 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 contemporaneous
comments and oral or written agreements concerning
warranties.
