1 Charger
2 Control board
Remove all connector plugs from the control PCB
and the charger.
Remove the entire sheet metal plate from the ap-
pliance.
Replace the control PCB or the charger.
Installation in reverse order
Note
If you cannot clearly determine whether the electron-
ics are defective in case of a malfunction, the battery
should be separated from the appliance for about 10
seconds.
This is necessary for the energy cells (capacitors),
which will support the processor voltage for a while,
to be able to drain completely in case of problems.
Switching off the key switch does not guarantee that
the supply voltage of the controller has been discon-
nected.
If the appliance works smoothly after that, the elec-
tronics are functioning and do not need to be re-
placed.
This problem can occur, e.g., if there has been an
electrostatic discharge.
