10 Disposal

Most of the materials from which Hilti power tools or appliances 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 power tools or appliances for recycling. Ask Hilti customer service or your Hilti representative for
further information.
For EC countries only
Do not dispose of electrical appliances together with household waste.
In observance of the European Directive on waste electrical and electronic equipment and its implement-
ation in accordance with national law, electrical appliances and batteries that have reached the end of
their life must be collected separately and returned to an environmentally compatible recycling facility.
Disposing of drilling slurry
Disposing 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:
1. Collect the drilling slurry (for example, using a wet-type vacuum cleaner).
2. Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site (the
addition of a flocculent may accelerate the separation process).
3. 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.
Disposal of drilling dust
The drilling dust collected must be disposed of in accordance with the applicable national regulations.
Possible cause
The container is full.
The motor overheating protection cut-
out has been activated.
The motor overheating protection cut-
out switches the motor off repeatedly
as the ventilation slots are clogged.
The electric tool is faulty or is not
plugged in fully.
No suction hose is connected.
Remedy
Switch the appliance off. Empty the
container.
See section: 7.8.2 Emptying the
waste material container when no
dust bag is fitted (collecting liquids)
Switch off the appliance and allow
it to cool for 5 min. If the motor still
doesn't start, contact Hilti Service.
Clean the ventilation slots carefully
with a dry brush.
Check the electric tool for correct op-
eration and plug it in fully.
Connect the suction hose.
