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 representative for further information.
In accordance with the European Directive on waste electrical and electronic equipment and its implementation in conformance with national law, electric tools or appliances that have reached the end of their life must be collected separately and returned to an environmentally compatible recycling facility.

Drilling slurry
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.

We recommend the following pretreatment:

• Collect the drilling slurry (for example, using a wet-type vacuum cleaner)
• Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site (addition of a flocculent may accelerate the settling process).
• The remaining water (alkaline, pH value greater than 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.

Drilling dust

• Dispose of the drilling dust collected by the vacuum cleaner in accordance with the applicable national regulations.

Manufacturer’s warranty

• Please contact your local Hilti representative if you have questions about the warranty conditions.
