Lasoya Pressure problems

[bcelos]

Ok, so i have my Lasoya Promaster for a few weeks and its been working great. I had a tournamnet today and everything seemed to be working great. After a few games, I was dry firing to empty my tank which had about 500psi in it, so I could go refill it. Emptied the tank and turned off and cleaned the gun. I went to play another game screwed back in the tank, and when I was shooting it would shoot a few shots then stop, and I noticed that the eyes seemed to be turned off, and wouldn't turn on. I unscrewed the tank and tried again when I noticed that on the High Pressure Reg gauge the needle was past the 600, and its been at 250 the whole day. Also when the air was screwed in the bolt didn't cock back.

I am using a PMI 72 CI, 3000PSI tank

So now whenever I screw in a tank the gauge goes past 600 and I cant shoot or dryfire due to the bolt not cocking itself as it should.

Any ideas???

Uhm... is your gun completely stock? I had this problem with my bushmaster when using an upgraded valve system.

it might be ur tank

You can try this...
add 3-4 drops of cup seal oil into your asa, screw in your tank and try to dry fire like that. Had somewhat of the same problem like you and someone told me to try that and it worked. Good luck man.

Yes My gun is completly stock

Ive tried with another tank, however is was the same size

I'll try the oil

cup seal oil? Well I wouldn't put oil in my marker in any hurry but it's not my marker.

I would first try zeroing out all your regs first before going out and buying anytihng. Just zero your regs out then turn up your LPR untilthe bolt cocks then one more half turn

Yeah zero-ing out the regulators would most likely solve the problem, or you could take apart and clean the HPR if you experience regulator creep.

make sure you only put synthetic oil in your gun, nothing with petroleum in it. in fact since promasters use grease-type lube in the solenoids its best to use that style lube for the entire gun instead of liquid style lubes. Dow33, Shocker Lube, Super Lube, etc can all be used.

first try turning down your inline to zero, and resetting the regs to the proper pressures. If that doesn't work, take apart the reg and flip the reg seat over to the other side (in case one side is scratched) and lube all the o-rings and seals in the inline. reassemble and see if the problem reoccurs.

Yeah, ICD regs can be screwy sometimes, depending on how they've been treated. If you haven't ever cleaned the reg and you've had the gun for a while; then chances are the hpr / lpr need some cleaning :)
At least this was part of the case with my bushy; it needed excessive cleaning.

Turns out It needed a new cup seal or something like that...
