10. Disposal

Most of the materials from which Hilti power 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 sales representative for further information. Should you wish to return the electric tool yourself to a disposal facility for recycling, proceed as follows: Dismantle the tool as far as possible without the need for special tools. Use absorbent paper to wipe oily parts clean and collect any oil that runs out. This paper should also be disposed of correctly. On no account should oil be allowed

to enter the waste water system or find its way into the ground. Separate the individual parts as follows:

Part / assembly Main material Recycling

** With regard to environmental aspects, allowing drilling slurry to flow directly into rivers, lakes or the sewerage

system without suitable pre-treatment is problematical. Ask the local authorities for information about applicable regulations.

We recommend the following pre-treatment:

●Collect the drilling slurry (e.g. use an industrial vacuum cleaner).

●Allow the slurry to settle and dispose of the solid material at a construction waste disposal site (the addition of

a flocculent may accelerate the settling process).

●Water from the drilling slurry (alkaline, ph value < 7) should be neutralised by adding an acidic neutralising agent or large quantity of water before it is allowed to flow into the sewerage system.
