Description of the LED display on the tool
The light-emitting diode together with the electronic control system serves to
provide information about the battery charge levels and the tool.

When the battery is inserted, the light-emitting diode flashes a few times. This means that the
electronic control is performing its self-test satisfactorily.
Attention! Wait approx. 30 seconds between removing the empty battery and inserting a charged
one so that the self-test can be carried out.
If the diode displays a steady light for about 20 seconds after a work operation, this means that the
battery is empty and needs to be charged..
If the diode flashes for about 20 seconds upon completion of a work operation, this means that
maintenance needs to be carried out (after 20,000 joints). The tool should be sent to the REHAU
service center as soon as possible.
If the LED lights up for 20 seconds and then flashes, this means that the battery is flat and also that
maintenance is due.
If the diode flashes quickly for about 20 seconds, this means that the tool is overheated.
Allow for the device to cool down before using it again.
If the light-emitting diode flashes once and emits a signal tone during the compression process, either the
necessary pressing force was not reached or the pressing process was manually interrupted. The
joint made in the compression process may not have been created properly and must be
inspected.
If the light-emitting diodes and the workspace lighting flash three times and if a signal tone is
emitted at the same time during the compression process, there is a serious malfunction. The
pressing force is not being reached when the motor is running. The joint made in this compression
process may not have been created properly and must be inspected! The tool should be sent to
the REHAU service center for repair as soon as possible. Should this malfunction occur three times
in succession, the device will switch to malfunction and will need to be sent to the REHAU service
center for repair.
