11. Disposal
Disposal of the machine
Return waste material for recycling
■
Machine and packaging must be sorted for environment-friendly recycling.
■
Plastic components are marked to facilitate categorized recycling.
Only for EU countries
Disposal of electric tools together with other household waste is not permissible!
In observance of European Directive on waste electrical and electronic equipment and its implemen-
tation 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.
Disposal of drilling and sawing slurry
■
With regard to environmental aspects, allowing drilling or sawing slurry to flow directly into rivers, lakes or the
sewerage system without suitable pre-treatment is problematical.
■
In addition to the following recommended pre-treatment procedures, the applicable national regulations must
be observed when disposing of drilling or sawing slurry. Ask the local authorities concerned for further infor-
mation.
We recommend the following pre-treatment
■
Collect the drilling and sawing slurry (e.g. using a suitable industrial vacuum cleaner).
■
The fine content of the drilling and sawing slurry should be separated from the water by allowing it to settle
(e.g. leave standing for some time or add a coagulation agent).
■
Solid material from the drilling and sawing slurry should be deposited at a construction waste
■
Water from the drilling and sawing slurry should be neutralized (e.g. by adding a large quantity of water or other
neutralization agents) before it is allowed to flow into the sewerage system.
