NickDoes anyone know how this works ?. I have the instructions which are brief. I can't get it to depress fully. The instructions say it has to be between divisions on the ring. It isn't seized as it will move.

cheers

Thanks John, yes thats the manual and it says '

c) Rapid Return without changing sense of rotation or stopping the work­spindle, is initiated as follows, after disengagement of the cross feed: Depress button for rapid return (1) using the lever suppiied, and hold retaining ring (6) with stop rod.

Slide (13) will immediately withdraw at a rate of ,02"•.04" in dia
(0,5 mm􀄢 1,0 mm in&cent. Return button (1) may also be depressed before the automatic end release has become operative; the advance movement will then be arrested immediately and the slide withdraw.
If depressing return button (1) with the work spindle at rest:
Has stop pin (11) been hit either by slide (13) at the end of the advance movement, or by stop (12), unclamp the slide by turning collar
(7) contrary to the direction of arrow.
Thereupon depress return button (1) as follows:Turn retainine ring (6) until r,eturn button (1) comes to stay between two divisions of scale (7); press button (1), stop retaining ring (6) using the stop rod, and c􀁪cage clockwise rotation of the head.

Which doesn't seem to make sense or work.

I have a UPA2 head and that is exactly how it works. A stop is set and the head feeds out slowly to that diameter while you hold the stop rod and when the stop is reached the head then trips out. Still holding the stop rod and with the machine spindle still rotating you depress the return button and the slide rapids back to centre.
