well just in case you`ve been into the gun, after taking the grips off, you`ll see the air tube , 2 x screws holding the top to the bottom, undo those, the whole thing should just separate, and what you can see very blatantly is the upper tube and the Solenoid, Unscrew the tube, then unscrew the silver barrel ( which happens to be the Solenoid ) but just as you do this = check to see if the connection is properly in place, I`m talking about the lead connector that just pushes in. use an allen key to push it in properly ??
before doing anything else , turn the gun on , and touch the part where the trigger touch or should I say where they connect and listen for that Clicking, if it is ?? there`s nothing wrong ??
If it doesn`t ?? then unscrew that round shiny cylinder and possibly borrow another from a friend that has an Axe ? ( don`t worry you can`t do any harm ) if it clicks ? you`ll know the problem.
have a look at the Solenoid after this and look to see if it`s all together as sometimes they come apart, this is usually because of firing the gun ABOVE 200psi.
If you need another ? Just Paintball ( Top of the page ) sell them for peanuts.
Please check your battery and don`t use anything else other than a Durracell Battery as these give out 9.2 , all the others around 8.6.
sometimes buying a brand new one can be low charged, Check out a Pound shop around you to buy a Battery Tester = £1 then when you buy a Battery you`ll be able to buy the best on the shelf Ha Ha Ha, I laugh but it works !!
