Explanation
The screwdriving operation has been
carried out properly. The preset shut-
off criterion (e. g. the torque) has been
achieved.
The screwdriving operation has not
been carried out properly. The
required shut-off criterion (e. g. the
torque) was not achieved. Alterna-
tively, a preset error criterion (e. g. a
too large rotation angle) was achieved.
The remaining battery capacity is
below 25 %. The battery must be
changed in foreseeable time.
The battery is discharged and must be
changed.
The power tool has a major defect.
The power tool must be repaired by
the after-sales service.
– Problem with battery. Please contact
the after-sales service.
– The power tool can not be operated
with the battery type being used.
The power tool has a minor defect,
such as blocked motor. The power
tool is blocked in order to protect the
internal components. Remove the bat-
tery and mount it again. Ensure correct
handling when performing the next
screwdriving operation.
The machine is overheated, the over-
temperature protection has
responded. After cooling down, the
machine is ready for operation again. If
the over-temperature protection
responds several times briefly after
each other, have the power tool
checked by the after-sales service.
The battery type is not suitable for this
screwdriving application.
Recommendation: For soft screw-
driving applications at high torque, use
a battery with higher capacity.
