Hilti TE 25 Mode D'emploi page 10

Remember before starting
to work
When working with the machine, it must
be held two hands. Always make sure that
you have a safe stance / foothold.
1. The electric supply must be the same as
given on the TE25 nameplate.
2. The TE25 is double insulated and must
not, therefore, be grounded (earthed).
3. Applying excessive pressure will not in-
crease the TE25's performance. Just posi-
tion the bit and guide it into the hole.
4. Check that you have set the right speed.
Please refer to the enclosed safety pre-
cautions.
Clean the drill bit: The chucks is not in-
corporated in the lubricating system of the
TE 25. Drill bit connection ends must there-
fore be cleaned regularly and sprayed spar-
ingly with Hilti lubricant.
Shorten the start-up time at low tem-
pertures by jolting the drill bit briefly against
the work surface when starting the TE 25.

Disposal
Most of the materials from
which Hilti power tools are man-
ufactured can be recycled. The
materials must be correctly separated
before they can be recycled. In many
countries, Hilti has already made arrange-
ments for taking back your old electric
tools for recycling. Please ask your Hilti
customer service department or Hilti
sales representative for further informa-
tion.

Disposal of electric tools together with
household waste is not permissible!
In observance of European Directive
2002/96/EC on waste electrical and elec-
tronic 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 compati-
ble recycling facility.
