The problem I am having is getting the collars on the vertical rod adjusted so that three things happen.
First of all, the pull on the game start handle needs to be able to reset the score reel. The upper collar needs to be set high enough on the thin sliding vertical rod to get the spring tension needed to pull the inner sliding rod down to reset the reel.
Second, after pulling the ball release handle by the player it should go back fully to its initial position.
Third, the vertical rod must raise back up enough so that the arm that catches and moves the reel during reset returns back to the point that it can catch and reset the reel again in a new game.
I can only get two of these requirements to work on a reset. Changing the collar position to increase or decrease the spring tension will correct one fault but then another issue fails.
If you have a manual is there anything in it about adjusting these collars?
Also how would you adjust the closing force of the hydraulic door closer to increase the closing force of the piston?
