as above lads any help please
regards dave
Seals may be damaged. Gas leaks are not a common problem with these afaik so its probably damaged somewhere.
seals can normally be had from chambers airgun spares
to fit the new seal you need to strip the gun down abit to access the seal as the old seal is dead fish it out with a thin flat blade screwdriver carfully then put the new seal in and seat it down with something blunt so as not to damage it
if your not confident take it to your local airgun shop and see if they will do it for you
thanks lads phoned brocock its going back tomorrow thanks for your help

I think you'll find there are no spares available for these at all,unlike all the other umarex pistols.Why that is I don't know.
