Only use drive attachments that correspond to guideline ATEX

The explosion-proof air drills correspond to the design requirements of
the design group I M2 and II category 2 G, or IIB Gb. Those drills are
suited for the installation into Zone 1 and Zone 2.
You can find the temperature class that is permitted for the air motor on
the model tag (Ex-Protection-Marking).
All air drills must correspond – for a minimum – with the standard
EN 60529 of the protection class IP 54. They are designed for the used
in dusty or damp environments.
Make sure that the drill is sufficiently ventilated and that there is no
additional warming source (i.e. such as a clutch, inserted tools).
Open inlet- and exhaust ports are not permissible. Those type of ports
have to be closed, using either a fireproof filter or hosing. If only hosing
is connected to any of the open ports (without the use of a fireproof
filter), then that hosing has to be piped out of the explosive area.
Only used hoses or piping suitable for explosion-hazardous areas for
connecting the drill.
The possible entry of any solid particles into the compressed air inlet
must be prevented!
