▶ Clean the maintenance area in a way that prevents hazardous substances escaping into the surrounding
environment.
▶ Vacuum off the outer surfaces of the appliance and wipe it clean or seal it in a suitable container, e.g.
large plastic bag, before removing it from an area contaminated with hazardous substances. This will
help to avoid distribution of the hazardous dust deposited on it.
▶ When maintenance or repairs are carried out, all contaminated parts which cannot be satisfactorily
cleaned must be packed in impermeable bags and disposed of in compliance with the applicable
disposal regulations.
▶ The appliance must be subjected to a technical inspection by Hilti Service or a trained person at least
once a year to check, for example, for damage to the filter, air leakage, and to ensure correct operation
of controlling devices.
8.2 Automatic filter cleaning
Note
Do not attempt to clean the filter element by knocking it against a hard object and do not use pointed
instruments. This will reduce the life of the filter element.
Do not use compressed air to clean the filter element. This may cause tears in the filter material.

11 Disposal
Most of the materials from which Hilti products 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.
In accordance with the European Directive on waste electrical and electronic equipment and its implementation in conformance with national law, electric tools or appliances that have reached the end of their life
must be collected separately and returned to an environmentally compatible recycling facility.
▶
Do not dispose of electric appliances together with household waste.
Drilling slurry
Disposal of drilling slurry directly into rivers, lakes or the sewerage system without suitable pretreatment
presents environmental problems.
▶ Ask the local public authorities for information about current regulations.
We recommend the following pretreatment:
▶ Collect the drilling slurry (for example, using a wet-type vacuum cleaner).
▶ Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site
(addition of a flocculent may accelerate the settling process).
▶ The remaining water (alkaline, pH value greater than 7) must be neutralized by the addition of an acidic
neutralizing agent or diluted with a large volume of water before it is allowed to flow into the sewerage
system.
Drilling dust
▶ Dispose of the drilling dust collected by the vacuum cleaner in accordance with the applicable national
regulations.
