it sits above the draw bar normaly and the air cyl shoves the motor assembly down to engage the draw bar , air cyls are in the same air circut as the motor so it spins at the same time the cyl shoves it down on to the draw bar. I used the original valve off the back of the red impact wrench, push the button and it ejects the collet and tool out into my hand in about 2 seconds

Didn't realize that was an impact wrench.

All I can say is, you must be Scottish!
