The sleeve must be prised open with a tool. Under this sleeve there is a small screw which is the cause of the blockage. The screw must be screwed in a little, half a turn to a full turn at the most. The screw serves to stabilise the sleeve; if it is turned in too far, the handle will have too much play.
If this does not solve the problem for you, please contact our support team at support@moovi.de.
