The switch S25 determines the forward end position of the transport
carriage. In this position the clearance x from the front edges of the
forward-lying needles to the front edges 2 of the transport clamps must
be:
x = 336 mm at 180 mm sewing distance
x = 376 mm at 220 mm sewing distance
The switch S15 serves as a safety switch. It prevents a possible
striking of the transport carriage on the machine head.
The clearance between the switches S25 and S15 must be approx.
90 mm.
