Hi All,
I have a new finishline FL3 paint gun(actually I bought it new a year ago, and am just now using it) and I cannot seem to get 30 psi when pulling the trigger. It drops all the way down to 5psi. I set the air guage all the way up to 120 psi with trigger closed, but when pull it, I still only got about 5-10 psi. What gives??
I can thread the same air guage on my cheap harbor freight gun and get 30 psi with trigger pulled but not the finishline. Is the Finishline a big air consumer?

I'm not sure what your HF gun is (HVLP?) but the Finishline gun is HVLP and could certainly be sucking down more air than your other gun. What size compressor - what CFM does it claim to produce?
If your pressure @ gun handle drops to 5PSI immediately then something else might be going on. |

Screw gun directly onto the compressor outlet (no hose, etc.. probably put a regulator first though!) and see what happens.. If you're tank isn't dropping to 5psi with the gun, something is funky.This will bypass those variables.

It is an HVLP and I gave wrong model, Its FLG3. dont know why PSI drops to 5psi at pull of trigger, my harbor freight guns can get 30-35 psi at pull of trigger with same compressor, line, and air regultor.
Here is the model Im talking about second from top . http://www.tcpglobal.com/spraygundepot/ ... hline.aspx |

ya got the packing nut tightened properly? have ya tied( dont know ifeen it'll help) running some sovlent though the gun?

strip the gun down and clean ,check the air inlet ,that nothing has crept up there as its been sitting around for a year.
fail to prepare ,prepare to fail.

If the pressure drops to 5 PSI, doesn't that mean you have a serious leak?
If it's plugged, wouldn't that mean higher pressure on the gage? I don't understand. JC.
