Each ball is manually plunged into play, hitting the multi ball( yellow target,left hand side above left sling ) will cause another ball to be automatically plunged into play.
Once all claw letters are lit, you can use second button to use claw save.........C L A  W flashes as a "timer", approx 5 seconds that you can reuse the claw save until the claw letters extinguish and the claw save button cannot be used again.........if that makes sense.

Thanks for that info ,

So obviously this machine has an issue in that it auto ejects EVERY ball EVERY time.

And the CLAW - OK , I took the flash of ( word ) Claw to be that it thought we had depressed the button but it didnt move the claw, so the issue could still be the switch itself then.

Cheers
