Disposal; Manufacturer's Warranty - Hilti DD 120 Operating Instructions Manual

Fault
Excessive play in the drilling
system.

10 Disposal

Most of the materials from which Hilti machines 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 old machines and appliances for recycling. Ask Hilti customer service or your Hilti representative for further
information.
For EC countries only
Disposal of electric appliances 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
must be collected separately and returned to an environmentally compatible recycling facility.
Recommended pretreatment for disposal of drilling slurry
NOTE
The disposal of drilling slurry directly into rivers, lakes or the sewerage system without suitable pretreatment presents
environmental problems. Ask the local public authorities for information about current regulations.
1. Collect the drilling slurry (e.g. using a wet-type industrial vacuum cleaner)
2. Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site (the
addition of a flocculent may accelerate the separation process).
3. The remaining water (alkaline, pH value > 7) must be neutralized by the addition of an acidic neutralizing agent or
diluted with a large volume of water before it is allowed to flow into the sewerage system.
