AEH2

I just got a TES and I'm having a little trouble. It seems to have two problems. It will not fire a ball with the eye on. If I turn off the eye it will fire and I can take the little cover loose and pop out the eye and cover it with my finger and it will fire with the eye on, it just won't fire with a ball blocking the eye. It will "click" with the eye on if I just put a piece of paper down in the barrel and block it. Any suggestions?

Second problem is that there seems to be no difference in auto and semi. When in auto it will only fire once per trigger pull. Is it supposed to be automatic or not? If not, whats the difference.

The manual seems to be pretty lacking. I have not read every page yet but I've seem nothing about the "dwell" Whats it do and where should it be set?

I have no experiance with paintball guns, But have bought my 11 year old a Tippman and myself this TES. Any set-up advice and tips will be greatly appreciated. I'm trying to read as much as I can and have found a lot of good info here. I'd appreciate any links to good threads you think will be of help.
