The uncoupler uncouples correctly but then the system seems to rely on gravity to return to the normal coupling position after an uncoupling operation. One coupler now appears to defy gravity and stays in the raised position. Thus making it useless for further coupling operations. How can I fix this, what do you think about a little drop of oil, or should I send it back to Marklin ? Tim

Companies always try to get out of warranty issue if they can find an excuse. John
