I wonder if all DevilBiss gun's are that way? The nice man from UPS left my PRi Primer gun at the door yesterday and I'm itching, I say itching, to play with it.
I have a SRi gun and I set that one up the way I do all my guns. I get it set to the recommended PSI with the Fan and Fluid on the gun the way I want by pulling the trigger and just spraying Air.
Then I put in the material and do a spray out on a piece of masking paper taped to the wall and final check the PSI and other gun settings.
