Adjustment when the machine does not return to the top position: To check that the operation is
correct, depress the pedal and allow the machine to cycle until it stops. If it doesn’t stop in the top
position then adjustment needs to be made. Inch the beam until it reaches the top position.
Loosen the positioning screw and rotate the cam until the travel switch moving arm roller is in
line with the highest part of the cam. Adjust the adjusting screw of the moving arm until the micro
switch is closed then re clamp it.
Depress the pedal and check if the machine returns and stops in the top position. If the position is
incorrect repeat the adjustment again.
