Space requirements for operating and maintenance
Whenever possible, keep a free space for operating and maintenance of about
2 m around the drill position, so that you can work safely and have immediate
access in case of a failure.
Drilling
At the beginning, drill very slowly, since the drill bit does only starts cutting with
a fraction of the cut surface in the material. If you drill too fast or with too much
pressure, the drill bit could get jammed.
In order to reach the max. drilling depth, you probably have to use an
extension for the drill bit!
