Disposal

WARNING

Risk of injury due to incorrect disposal! Health hazards due to escaping gases or liquids.

• DO NOT send batteries through the mail!
• Cover the terminals with a non-conductive material (such as electrical tape) to prevent short circuiting.
• Dispose of your battery out of the reach of children.
• Dispose of the battery at your Hilti Store, or consult your local governmental garbage disposal or public health and safety resources for disposal instructions.

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.

• Do not dispose of electric appliances together with household waste!

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 flocculant 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.
