10 Disposal
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 right away. Keep them out of reach of children. Do not disassemble or incinerate the
batteries.
CAUTION
Batteries that have reached the end of their life must be disposed of in accordance with national regulations or returned
to Hilti.
Most of the materials from which Hilti power 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 your old power tools or appliances 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 the European Directive on waste electrical and electronic equipment and its imple-
mentation in accordance with national law, electrical appliances that have reached the end of their life
