10 Disposal
Most of the materials from which Hilti tools and appliances 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.
▶ Do not dispose of power tools, electronic equipment or batteries as household waste!
10.1 Pretreatment of drilling slurry for disposal
The disposal of drilling slurry directly into rivers, lakes or the sewerage system without suitable
pretreatment presents problems of an environmental nature. Ask the local public authorities for
information about current regulations.
1. Collect the drilling slurry (e.g. using a wet-type industrial vacuum extractor).
2. Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site
(adding a flocculant can accelerate the settling process).
3. Neutralize the left-over water (alkaline, pH > 7) by adding acidic neutralizing agent or diluting it with a
large quantity of water before it is allowed to flow into the sewerage system.
