Date of receiving: 06-12-2011
Machine story: 09-12-2011 The machine worked on arrival, but after a calculation (rotating of the crank) the crank and the reset of the shifters are blocked / disabled. With a little force ore back and forward of the reset input crank, it will released.
This is a common problem with a lot of Pinwheel machines. The mechanism that prevent rotating the pinwheel, is controlled by the internal pin, in the crank grip. This collect dust etc and this prevents the internal bar to lever the bar intern in the pinwheel. Oiling the complete mechanism and move it a few time by hand will often solve the problem. So did it now, in perfect working condition again.
