Disposal
Handling drilling slurry
Drilling in mineral materials (e.g. concrete) with the DD EC-1 diamond core drilling machine produces drilling slur-
ry. As with fresh cement mortar, this slurry may cause irritation if allowed to come into contact with the skin or
eyes. Wear protective clothing, protective gloves and goggles.
With regard to environmental aspects, allowing this slurry to flow directly into rivers, lakes or the sewerage sys-
tem without suitable pre-treatment is problematical.
Disposal procedure
In addition to the following recommended pre-treatment procedures, the applicable national regulations must
be observed when disposing of drilling slurry.
Ask the local authorities concerned for further information.
Recommended pre-treatment
■
Water from the drilling slurry must be neutralised (e.g. by adding a large quantity of water or other neutralisa-
tion agent) before it is allowed to flow into the sewerage system.
■
Solid material from the drilling slurry should be deposited at a construction waste disposal site.

Return waste material for recycling
Most of the materials from which Hilti electric tools 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 electric tools for recycling. Please ask your Hilti customer service department or Hilti rep-
resentative for further information.
Only for EU countries
Disposal of electric tools together with household waste is not permissible!
In observance of European Directive on waste electrical and electronic equipment and its implementa-
tion in accordance with national law, electric tools that have reached the end of their life must be col-
lected separately and returned to an environmentally compatible recycling facility.
