LED Angel wont fire in cold weather.

[Mr. Wagner]

Anyone else have this trouble, or any suggestions as to what to check to correct it?

[Pman69]

r u using nitrogen or c02?

[Mr. Wagner]

compressed air

[Pman69]

wut do u mean by, it wont fire?

[Mr. Wagner]

just hear a clicking but the bolt wont cycle

[Pman69]

hmm, maybe sumtin with the ram, im not too sure tho

[Crazy4Paintball1]

Will it fire if you take it in the house? Or somewhere warm? Also is there a ball in the breech or anything that could restrict the bolt from moving? Do you have good air flow to the gun?

[Mr. Wagner]

If you warm the gun up it operates perfectly. There is nothing obstructing the bolt, and I have plenty of air in the tank. When the gun is cold however only the relay operates when you pull the triger.

[Crazy4Paintball1]

hmm that is really weird. I have no idea. I have been shooting led's for 4 years now and not once have I ever had or seen that problem with mine or anyone elses. You got me stumped.... I will ask around and see if I can find anything out.

[kinetisist]

Just out of curiosity are you using an aluminum bolt .. if so is it a snug fit meaning if the bolt fits with little play and operates perfectly in warm weather but not in cold it is swelling and you might want to try a delrin or just remove the bolt and see what happens .. that is the only thing I can think of that might cause problems

[Crazy4Paintball1]

I really really hope you aren't using an aluminum bolt in your gun as that would just be plain stupid...

[Mr. Wagner]

No, the bolt is delrin and the gun wont fire even if its removed from the gun. I think the problem is with the RAM valve. I have a tool kit, could you tell me how many shim washers I should have, and what they adjust. Also if I put a pressure guage on the port under the barrel what should it be reading?

[Crazy4Paintball1]

The Shims are for your LPR not your ram. To adjust your ram you need to open your backplate and adjust it from there. The thing that I dont understand is the ram really should'nt be causing a problem if the gun shoots when its warm just not when its cold. The ram isn't changing any....I could be wrong but that is just my assumption.

[Mr. Wagner]

I was thinking maybe the lubricant in the ram was thickening up when the temp droped and maybe preventing the ram from operateing. I soaked the ram in alchool to get out all the lubricant I could, and then relubed it with the angel lube. Didnt seem to help. Anybody got any other ideas???

[pimpinsaylor]

try pitting oil in your macroline and dry fireing it for 50 shots. If that dosent work take the ram out and grease that bad boy up

[Crazy4Paintball1]

Well he said he already cleaned the ram and re lubed it and still had no luck....I am absolutley stumped as I am sure you are too. I would go ahead and give an MT a call and see if they know what is up. They might be able to point you in a direction we haven't thought of yet. Let us know if they tell you how to fix it and stuff, just so we will all know...lol

[BakWoodz]

I actually had this problem myself this weekend. In my case it was the field paint not being meant for cold weather. When the gun tried to fire, the paint was lodged in the chamber so tightly that I had to take off the barell and jam a squeegie in to dislodge it. They replaced the paint with some that was ok for cold weather, and the gun worked fine for the rest of the day.

[Mr. Wagner]

My problem isnt the paint, as the gun wont even dry fire below 40 degrees. Can anyone tell me what the shims in the Low Pressure chamber adjust, how many I should be running, and what pressure reading I should have there?

Also where I could pick up some more shims would be nice if anyone has a link handy.

[Crazy4Paintball1]

The shims in your LPR adjust the pressure. I belive you should be running around 82 psi. The number of shims all depends on what your pressure is as now. You will either have to add or remove some to get that designated pressure. There is no universal number as each gun is different. Any of the MT's will have shims that you can buy. www.angelparts.com

etc...

[Mr. Wagner]

My LPR is running at 120. Guess I need to be getting that set down a bit.

[Crazy4Paintball1]

Yeah that is a bit high. I just double cecked the LPR setting and for the LED it should be around 90 psi, so you need to take some shims out...lol

[Arctic_Wombats]

Thats strange I just played in the snow and it was 20 out and my gun worked awesome. Paintballs were another story. Its around 90psi, I think mine is like 88 or 87psi. I dont think that will fix your problem but it cant hurt. Its got to be somethign that expands when it is cold and that expansion prevents something moving. What kind of hammer do you have?

[LightEmUp13]

my gun has this same problem

[hgroberts]

its pm'ed to ken

[BoB]

I would replace the snap oring and ensure the snap ring retaining screw is adjusted correctly.

[Crazy4Paintball1]

I would replace the snap oring and ensure the snap ring retaining screw is adjusted correctly.

Would that O-ring cause it to stop shooting in the cold? Or is it because it is expanding or something? Thanks Bob..

[BoB]

It could but best to start fresh and then break it down from there.
