11. Disposal
Return waste material for recycling
Most of the materials from which Hilti tools or machines 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 machines or tools for recycling. Please ask your Hilti
customer service department or Hilti sales representative for further
information.
Disposal of drilling slurry
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 a wet-type 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 neutralized by
adding an acidic neutralizing agent or large quantity of water before it is
allowed to flow into the sewerage system.
Only for EU countries
Do not dispose of electric tools together with household waste
material!
In observance of European Directive 2002/96/EC on waste
electrical and electronic equipment and its implementation in
accordance with national law, electric tools that have reached the
end of their life must be collected separately and returned to an
environmentally compatible recycling facility.
