I'm really proud of myself. I have the treadmill without construction sketch and without manual get into operation. The plug I have seen in the storage compartment immediately adjacent to the red power button. Connected to power (and on) lights Netschalter and display undaunted. After a brief period of the frustrations I remembered a plastic bag with small plastic parts. If I had almost thrown away ... Very lucky in my long life I was ever on a treadmill and have then identified the part as Nothaltschnur. Tuts now. Resumee A long life with technical experience will help! Of course, a sheet with the simplest instructions would have been helpful and a proper guidance and legal part?
