might have come off an assembly line doing a dedicated task

good point I dont think it reverses just one way, there's no turn nob

It should have a trigger, like a paddle thing. Have a look through any other bits and see if you can find it!

It should also have some sort of drive on the end, normally a 3/8 square (like the end of a ratchet) maybe it's just the other side in the photo?

Hard to tell without a photo of the drive end, but its an Atlas Copco torque-controlled wrench or screwdriver, 7 to 15 Newton-metres.
The small button is for on/off control of the air flow, operated by a paddle mounted on a pivot through the hole with recessed shoulders.

Have you a better picture of the drive. Looks like a collet drill to me

Here is a better photo of the square end

It's an Atlas Copco,
Part number might well be ltv26sr006

I expect it's come from an assembly line where it was doing the same job over & over.
For production you can set the incoming air pressure to achieve a desired torque.

It's possible that the trigger has been bypassed and it was previously used with a pull down or foot switch. Does it spin up if you plug it in?

will check out the trigger bypass when I get a min

It's odd that the roll pin that goes through the hole is missing.
Normally that (or part of it) gets left if the trigger is broken off or worn off.
I reckon it's been removed for some reason, either as spares for another or a bypass kit fitted.

It would be easy enough to make up another one if you wanted to get it working again but plug it onto an airline first and see what happens...

I connected this nut runner on line today it runs constantly, I had a look, now I have a better idea of whats meant to be happening, thanks to you guys. There is a grub screw srewed into where the trigger plunger goes.



I took the grub screw out to see whats what,I didnt lean anything from that,


I will see if I can make up a plunger thing when I feel like messing with it till then it will go back in the cupboard It not a lot of good to me but there maybe a little value in it to some one, if its fixed

Cheers to all for your help on this

Try it on the air line again with that grub screw removed and see if it still runs.
Maybe wrap a towel or something around it incase anything blows out of the hole.
