Hi Sellam I find it is easier to track what is going on by disconnecting the power to the motor. I can then rotate, using the fan, to get it to cycle through an action. You still have to manually lock up the clutches or they will drag. You do this by squeezing the two pieces that hang out and catch on the release lever. Once you got them locked up, you can type a key and cycle things one step at a time. Dwight
