Nizo 2056

Does anyone here have a Nizo 2056? I have tried and tried to figure out the run-lock feature but I can't get it....I think it has something to do with the slider under the handle, the power switch and the run button in the middle of the buttons on the left side..

Hello,
this link http://www.siltec.co.uk/amovies/books/nizo.htm might help. It has a key describing what the various buttons do on the 2056.
