Rapid shut-off (KickBack Control)
The rapid shut-off function (KickBack Control)
gives the user greater control over the power
tool and offers them better protection than
power tools that do not have KickBack Control.
If the power tool suddenly and unforeseeably
rotates around the drilling axis, it will switch off, the rapid
shut-off indicator (12) will light up red and the status
indicator (15) will flash red.
– To switch the tool back on, release the on/off switch (6)
and then press it again.
