taining no steel reinforcement.
The tool is faulty.
Have the tool checked at a Hilti ser-
vice center if the measuring tolerance
is exceeded.

ence fields.

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.
Most of the materials from which Hilti tools and 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.
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.
Dispose of the batteries in accordance with national regulations.
