Tuning Help with Dreamline

Generally can't fill an empty gun from compressor. Needs big air jolt to set the valve closed. Cock and shoot. Sometimes takes a couple times.

That gun should fill with 100 bar!

If it's a no fill problem, you should hear air escaping,. Since you have 100 bar ( you have cocked the gun and fired a pellet? They will fire with 100 bar!) If all this works, check the compressor drain valve. May not be tight/ sealed!
 
Well that's weird, the gun needs to be cocked ? and the first fill has to be done with a tank !! Strange nobody mentioned that, now I've got to find a paintball store. Mine was delivered with about 100 bar already in the gun so not quit empty.

Does the gun still have 100 bar in it? If it does then cocking it won't do any good, the valve in the gun is not hung open. When you try to fill it with your compressor, what does the gauge on the compressor read? Does the compressor gauge go up above 100 bar? If there is something wrong with the gun that it won't take air (some kind of blockage) then the gauge on the compressor should go up over 100 bar very quickly because all you are filling is the hose between the compressor and the gun.

Thanks for the responses guys.

I've fired the gun with a pellet it now reads just under 100 bar. The compressor drain valve I'm sure isn't a problem as I filled my other gun no problem after it failed with the Dreamline.

The compressor won't move above zero, it just sits there. My other gun it quickly rises to match the pressure in the gun (200 bar) and then fills normally. Interesting on reflection that it should reach 100 bar because it should just be filling the hose ... and it isn't. I've left it running for a few minutes and the pressure guage on the compressor just doesn't move.
So it's either the gun or the fill probe, doubt very much that it's the fill probe though.
 
Sounds like the female foster fitting my not be sealing well to the male foster fitting on the gun. These foster fitting don't all have the same tolerances and some fit looser than others. Try holding the female fitting tight to the male fitting as you run the compressor to see if it will seal. You may also wan to check the o-ring in the female foster fitting to make sure it's not worn.
 
I contacted the seller and they advised replacing the o-rings on the filler probe. These seemed to be in perfect condition but I changed them anyway and 'fiddled' with the fill probe connection to the gun. Now it charges, I will empty the resevoir on the gun (bit of plinking and zeroing) and see if the problem is fixed. Fingers crossed !!

Thanks again for the help guys, I have an aversion to covering my new gun with soapy water but if the problem persists I guess I'll have to, expensive way of blowing bubbles all the same :) I'll let you know how it shoots, my Vulcan 2 is laser accurate I'm hoping this will be the same.
 
Okay, I'm a bit confused... Does yours use a fill probe or does it have the male foster fitting attached to the gun? I have a Dream-Tac Compact and it has the male foster fitting. My Dreamline Classic uses a fill probe. Juast as an FYI, if yours uses the fill probe, a Hatsan Fill probe will also work. I've been using a Hatsan fill probe since shortly after I got my Dreamline Classic because I misplaced the FX fill probe and never found it! I have several Hatsan that I sold and I think I may have shipped the FX fill probe with one of them by mistake, but fortunately, the Hatsan Fill Probe works with it just fine. So, if you happen to have a Hatsan Fill probe handy, you may want to try it as well and see if it works better than the FX Fill probe.

I would NOT empty the gun. You are probably already below the regulator pressure if you are at 100 bar of bottle pressure. I don't think it is a good idea to shoot the gun when it is below the reg pressure. My advice would be to fill the gun to whatever the recommended fill pressure is and then shoot it some.

Ok, probably not 100% clear. I fully charged the gun after replacing the o-rings on the fill probe (no foster fitting on the gun) and now my intention is to empty the resevoir via zeroing and plinking and see if I can charge it again. Not possible to hear any air escaping though, it's like I'm putting the fill probe out of an open window and trying to charge the world to 230 bar.

Unfortunately I don't have a Hatsan, if the problem is persistant I may invest in a new fill probe though. Oh and my Dreamline Tac is the long/standard version where the fill probe is inserted into the end of the air resevoir, bit surprised at the length of the gun to be honest ... maybe should have bought the compact ...
 
That makes more sense, I have fixed many a leaking fill probe issue by just swapping the o-ring. I also recommend regularly lubing those 0-rings withsome silicone oil or diver's grease, it will help with wear anf tear and help them seal better. The o-rings make a difference also, I have a Hatsan fill probe that has the white nylon rings and it didn't seal well in the Dreamline. I replaced them with some black rubber (Dura 70 I think) and now it seals perfectly! Same sized o-ring, but I think the rubber 0-rings expand and seal better than the nylon o-rings.

That fully length Dreamline Tac, essentially the same gun as my Dreamline Classic, minus the wood stock, will make a lot more power than the Dream-Tac Compact! The longer barrel makes about 100FPS more than the short Compact barrel!
 
You know the air is not going in the cylinder, and you know it's being pumped out of the compressor. Doesn't that mean it has to be coming out the probe, or somewhere upstream of it? I assume that if the probe was somehow plugged up, the pressure would show building up in the compressor. Given what seems to be the only source of the leak, I'm just surprised you can't feel it escaping. 
 
Exactly, I smeared the fill probe with silicone grease, I'll have to look into those alternative o-rings. Where did you get them from ? Doubt I can buy them here in France but you never know.

I didn't realize you were in France! I was going to suggest the O-Ring Store, but you can probably get them off Amazon or a local hardware store. Or, you may be able to get some direct from FX or even Hatsan. The fill probe o-ring size for the Hatsan fill probe is 5.28mm inner diameter, 1.78mm width. Hatsan part number 2324. I was not able to find the specs of the FX Fill Probe on any of the Parts Sheets I have downloaded from their website.
