12. Disposal
Most of the materials from which Hilti power tools are manufactured can be recycled. The materials must be cor-
rectly 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 repre-
sentative 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 lubricated parts clean
and to collect the grease that runs out (total quantity approx. 50 ml). This paper should also be disposed of cor-
rectly.
On no account should grease be allowed to enter the waste water system or to find its way into the
ground.
The individual parts should be separated as follows:
