10. Disposal
en
CAUTION
Improper disposal of the equipment may have serious consequences: The burning of plastic components
generates toxic fumes which may present a health hazard. Batteries may explode if damaged or exposed to
very high temperatures, causing poisoning, burns, acid burns or environmental pollution. Careless disposal
may permit unauthorized and improper use of the equipment. This may result in serious personal injury, injury
to third parties and pollution of the environment.
CAUTION
Dispose of defective batteries without delay. Keep them out of reach of children. Do not attempt to open or
dismantle batteries and do not dispose of them by incineration.
CAUTION
Dispose of the batteries in accordance with national regulations or return them to Hilti.
Most of the materials from which Hilti tools or machines 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 your old tools for recycling. Please ask your Hilti customer service department or Hilti
representative for further information.
For EC countries only
Disposal of electric tools together with household waste is not permissible.
In observance of European Directive 2002/96/EC on waste electrical and electronic equipment
and its implementation in accordance with national law, electric tools that have reached the end
of their life must be collected separately and returned to an environmentally compatible recycling
facility.
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 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
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 national rules prohibit such exclusion. In particular,
26
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

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
