To repair/maintenance the shutter, it has to be released from the camera. It comes off as a complete unit. Open the camera remove the metal cover (the one which holds the two film rollers). Two srews on top, two screws on the bottom.
Inside the camera, there's a spring to push back the shutter release lever. It will fall out when removing the shutter so open the shutter and memorize its exact position. I didn't know this. Took me a long time to figure out the original position.
Remove the shutter controls which are located on the box except the cocking/high speed wheel, the slow speed scale and the index screw near the cocking/high speed wheel.
