Please define 'cleaning the marker'?Yes I have read the manual and I would recommend that you guys should to insted of jumping to conclusion and thinking you know all about it.
It clearly says double flash is for cleaning marker and emptying the air
How does being able to fire the beast with no ball in the breach enable you to 'clean the marker'. From a safety point of view I think the opposite would be true, as you'd want the marker to be safe, i.e. off and de-gassed before you start sticking cloth's, fingers, etc in it to dislodge paint, lube and paint shells from the internals.
Karma. I think some of us know a touch more than you, and we are attempting to pass on our knowledge and experience to help people like you in the forum, becuase basically thats how a forum works mate.
