9 Disposal
Most of the materials from which Hilti products are manufactured can be recycled. The materials must be
correctly separated before they can be recycled. In many countries, your old tools, machines or appliances
can be returned to Hilti for recycling. Ask Hilti Service or your Hilti sales representative for further information.
In accordance with the European Directive on waste electrical and electronic equipment and its implemen-
tation in conformance with national law, electric tools, machines or appliances that have reached the end of
their life must be collected separately and returned to an environmentally compatible recycling facility.
▶ Disposal of electric tools or appliances together with household waste is not permissible.
Drilling and sawing slurry
Disposing of drilling and sawing slurry directly into rivers, lakes or the sewerage system without suitable
pretreatment is problematic from an environmental point of view.
▶ Ask the local public authorities for information about current regulations.
We recommend the following pretreatment:
▶ Collect the drilling or sawing slurry (for example, using a wet-type vacuum cleaner).
▶ Allow the drilling or sawing slurry to stand for some time or add a flocculation agent to help the fine
particles in the slurry settle and separate from the water.
▶ Dispose of this solid portion of the drilling or sawing slurry at a construction waste disposal location.
