3.3 Machine characteristics
The machines are equipped with specially
developed electronics with soft start. It monitors
the speed and the green / red indicator lights
(items 1 and 2, see Figure
1
) help to achieve the
most favourable work progress and therefore tool-
protecting working conditions.
Visual display
Green:
Speed for optimum drilling
performance
Green / red: Speed within the limit range
Red:
Speed too low – stopping
If this warning signal is ignored, i.e. the feed is not
reduced, the electronics switch off on overload.
After the dry diamond core drill bit has stopped,
remove it from the drill hole. The machine can be
restarted immediately.
The machine is also equipped with a selectable
soft impact mechanism. It protects the diamond
segments of the core drill bits, allows faster working
and carries the drill dust away from the diamond
segments, which in turn enables a longer tool life for
the diamond core bits.
