Really Nice....
The Billy wing bolt is a fusebolt that has been polished.
if your low on air then matrix's will leak as there is not enough pressure to seal them.
Alot of matrix's leak when you air them up and it will stop when you have cycled the bolt a couple of times.

that link will also help you
This was a great link. We got some gas todays from a very nice man at Lips and nipped home to see if a decent amount of pressure and stripping and regreasing the bolt then cycling it would fix the air hissing out the back of the bolt .... it didn't
sooooo looked at the diagram above and replace the 4 o-rings it said could all cause air leaking out of the back of the bolt and it fixed it perfectly !!!
I still can't see any damage to th 4 o-rings we replaced but perhaps they have simply perished and softened with age ?? They certainly felt softer and less rigid than the newed ones ... what the hell it's all good.
I'll make 1 final observation. The shiney new EGO 09 I bought myself has a waaaaaaay better instruction manual than the DM9. Dye take note ?
cheers everyone who has helped and spent the time replying !
