OPEN SHED WITH SMALL PRESSURE ON THE TREADLE:
The right treadle is near the floor.
The arm A1 is at the top of the groove of the the arm guides G
The rolling white nylon piece N1 is on the top of the closed gate G1 so
the arm A1 will have to go down in the other groove avoiding a JAM
To do that the shed has to open all the way to the top guide TG all the
time.
