Re: Gun help? seems to be wasting a lot of material !
Wasting a lot as in......? Like is it shooting to much powder? If so, just lower the PSI some. Or is just a lot of it falling to the ground? Maybe you don't have a good ground or your just spraying to much in the first place, which could relate back to what I said up there^. -
Re: Gun help? seems to be wasting a lot of material !
I have one of those guns myself, and I've noticed it does like to waste if you're not careful. Shoot, my trigger's been stuck open for about a month now, so I have to use the screw at the bottom of the handle to regulate the flow/pressure. I've noticed it doesn't take a whole lot of pressure, so try turning that screw way down. Also, don't load the cup too full, I've found 1/3 full or less works well.Comment

kcrails,
Without a powder cup on, screw the air adjuster on the gun clear in and put about 60 or 70 psi to the gun. I'm pretty sure the adjuster is downstream of the trigger... you need some psi against the trigger to push it back out.
Adjust the screw out to set the pressure to the cup.
Did that make sense?

Can you put that in English ?

kcrails, in addition to what popeye said, you might be able to make the trigger work freely again by taking it apart, cleaning it, and lubing it with a little silicone grease. I did that to mine after the trigger began to stick and it made it work like new again.Steve Dold

Re: Gun help? seems to be wasting a lot of material !
First thing I'd do is take the diffuser tip of the gun and pitch it.
It just takes some time and practice... play around with different psi settings and different amounts of powder in the cup.
I wish there was a hard and fast answer but there isn't. I know it can be a little frustrating at first but you'll find the sweet spot with the gun.
It's the nature of the beast

Popeye,
Not too worried about fixing the trigger, it actually kind of helps me having it that way. When the trigger did work, it would glob a bunch out when I'd hit the trigger, didn't seem to matter where I set the pressure. I should probably upgrade to a pro-model gun anyway.
And the diffuser came off after my second botched job. Never had many issues after that.
JHFGSX9D,
How full is the gun cup? After the feed pressure, that's where I'd look. I generally keep mine below 1/3 full.Comment

Remove the little plastic tip on the end of the gun ? what will that do ?
