Airless or hvlp check your pressure and that the spray tip is clean if the pressure is too low the paint will gather on the tip

How do you take this hvlp gun apart for proper cleaning of the spray gun?

I've found over the years the least amount of times you can tear a spray gun completely apart the better. Usually a real good 'flushing' with lacquer thinner will suffice. I will take the air cap off and let it soak in thinner to dislodge any build up but other than that, I simply run thinner thru till it runs clear out the tip.

I also 'back flush' which involves having thinner in the cup and the air supply hose attached. the air pressure should be adjusted quite a bit lower than what you use for spraying paint.

Then you place a clean shop towel or rag over the air cap of the gun and pull the trigger. This forces air back into the paint cup 'back flushing' the gun. Then take the rag away from the cap and pull the trigger again to run thinner thru the gun the normal way.

IF you still want to tear the gun apart for cleaning you can hopefully get some idea with this video link;

Please provide correct paint viscosity to be used for Airless Paint Sprayer (item 60600). Include the method (standard) used to measure the paint viscosity. Thank you.

I had an airless sprayer years ago. I couldn't work out how to thin the paint either. The end result was if its too thick and wouldn't spray, I added more thinners. If it sprayed blobs and ran everywhere, I added a bit more paint. Not very professional but I got it down pat after a few errors. I wrote on the paint can I was using, the mix that worked the best.

Shoots drips

Most airless spray guns spit a bit when you pull or release the trigger because the paint between the spray tip and the paint valve is under pressure but not enough to atomise the paint. If you increase the pressure you may reduce the spit to a point when you don't notice it. A blocked filter could slow the paint getting through to the tip cause lower pressure.

We are having trouble getting the spray gun to pull the paint through. It will spray air but does not spray paint.

when you pull the trigger can u see the needle moving backward? if so, then it's either the paint is too thick compare to the nozzle size or the passage for paint is blocked. try to take the nozzle, needle and the cup off and give it a good clean!

Tdwbit269@aol.commy gun will not shut off even when i pull the trigger, liquid keeps flowing out. good thing is that i am getting something through the hose so that means my machine is working right?

You need a re-build kit for your gun.

The needle that pulls back when you squeeze the trigger is no longer making a seal when you release the trigger.
The problem is worse when you spray thin oil-based paints.

Depending on the gun, Sherwin Williams has kits for the Graco gun. That's where we bought ours for years up until I retired from painting.
Home Depot and Lowes may have parts.

Porter cable spray painter PSH1 it says what you can spray with it and I want to spray water base paint can I do it with this painter it is new and I didn't relize it was onl for laciur paint thank you...

Be sure to filter the paint you are trying to use so that you aren't dealing with large lumps of paint. You will need to experiment with hose pressure to get proper spray quality, and set the mixture control for a fairly fine mist as the paint is likely to be more fluid. Fan control is set so that you don't get an unpainted space in the middle of the paint swath. Make sure to wash the gun thoroughly after painting. If you are doing a lot of painting, expect some nozzle wear over time as the water base paint is somewhat gritty. Don't forget to trigger 'off' before the end of each stroke and trigger 'on' after starting the return stroke to keep running at a minimum. Good luck!

Spray guns

hey do not see any answers so here you go -First I am not an apprentice on this matter- I spray cars as a hobbie- controls can be determined this way-follow these steps look at the trigger typically the needle that is lowest on the handle will be the air -top most will be paint.Paint will be adjusted by feel- the air is easy to adjust-back the knob off all the way- hold trigger on fully depressed(without being hooked to air) turn knob until you feel it touch trigger-stop- this is now adjusted.

I do recommend you lose the syphon system -gravity will sevre you better- you will use less paint and it is better for enviroment.

Go to web site for new book- best of luck -I will watch for you- what are you trying to paint?
