Pop Riveter

Well Lads
Have a Pop make air riveter that's is leaking air at the trigger.
It.s also gone into the pull position straight away when plugged into airhose.
When disconnected it goes back to it.s original position.
Any ideas on what might be wrong.

The trigger valve stuck in the "on" position?, may be possible to strip the valve and lubricate the spool.

if it is a Genuine POP make, Part on Tools should have spares expensive
