Tuning New Air Force 50 CAL LSS won\\\'t fire any sugestions

[SteveEnglish]

I received a new LSS yesterday and after setting up it just clicks. Tank was pre-charged and everything looks good just won't fire.

Did you make any adjustments towards tuning the gun before firing? You think hammer is falling and not knocking the valve open? Increase hammer spring tension? Call up the place you bought it from? 

 

[SteveEnglish]

No I did not make any adjustments. I will call them but I did already send them an email. Will be Monday I think before I can get in touch. Thanks for your reply.

Did you take it OFF SAFE-?

Does your mother know you on her computer??????

 

[sasquatch]

Have you tried to turn the power wheel to max? You didn't say if you've tried messing with hammer tension 

 

[SteveEnglish]

It looks like it's almost at MAX but no I have not adjusted it. Was going to try that later today. Thanks

 

[sasquatch]

Maybe you got a melon if that thing is set to max and won't fire. But be sure the valve is not locked - according to the manual this could happen if tank is overfilled

Gun fires but projectile remains in the barrel Is the air tank filled? Is the barrel free from obstructions? Was the action closed and locked when you fired? Is the projectile of the correct caliber for the barrel? Are you sure the projectile did not exit the barrel? Remove the air tank and look through the rear of the barrel to verify that it is still inside. Is the tuner turned up high enough for the specific projectile? If the tuner is turned down, increase its tension on the striker spring by rotating it downward. Once you get the gun to fire, you can start backing the tuner down again to the desired level.

Gun fails to fire when the trigger is pulled Is the gun cocked? Has the safety been taken off? Is the removable air tank installed? Is the tank filled with air? Is anything blocking the valve or the bolt? Is the air tank overfilled, causing valve lock?

Personally, I'd try turning the power wheel *down* and see if it releases.

Yeah any adjustment in the power. Up, down, sideways if you could. User stated he had not tried. That's the first place I would be looking is hammer tension which is basically power wheel.

 

[SteveEnglish]

Just tried adjusting spring tension and that doesn't work either. The tank was pre-charged to looks like 3500 which should be good but as you suggested the valve may be locked.

Is THIS question directed towards me-?

I would retract the cocking lever a little bit and shove a wooden or fiberglass dowel rod and tap the projectile completely out muzzle loader style if the gun still won't fire after the safety is disengaged then remove the projectile then dry fire to see if any air comes out then go from there.

Put in vise, tap directly straight on the valve a few times with a rubber mallet. It will let air out. It’s just valve locked.

PLEASE point it on a safe direction with a good backstop if attempting to do so if the projectile is STILL in the breech.

 

[sasquatch]

Try draining the bottle to 3300 or 3000 psi and see if it makes a difference. 

 

[SteveEnglish]

Bleed bottle down to 3000 PSI and then 2000 PSI same result- Not firing. Did tap the end of the valve with a hardwood dowel and it does release air. Seems something isn't actuating the valve but have no idea what.



Thanks

Don't drain the bottle just remove it if you want to do that there is no sense in having a pump it back up. After you remove the bottle try working your safety back and forth. I have a funny feeling that it's in the safety. If this is a new gun that you purchased I would contact him place you bought it from and tell them what's going on. They may have you send it back to Air Force but those guys are great with customer service. You go screw around with it too much they're not going to warranty it.

Do you think that comment was directed towards ME-?

Wish I thought of that.
