Hello, Yesterday my Superstringer S90 arrived and despite some missing Flying Clamps and a couple of other tools I'm happy with my purchase. However with the instructions being all in German I'm struggling with the simplest of things. How am I meant to get the weight onto the lever arm? I would have thought the rubber end would have come off to let me slide it on but no matter how hard I pull I can't seem to get it off. Where am I going wrong here? Thanks.
