How To Use a Paint Sprayer.

What happens here

Most airless sprayers, regardless of brand, will have three main controls: a power switch, a pressure dial, and a prime valve. Locate the power switch, usually on the body of the sprayer. Identify the pressure dial, which adjusts the paint pressure up or down. Find the prime valve, often a small lever located on the lower housing. This valve typically has two positions: 'down' for prime (fluid goes through the prime hose) and 'up' for spray (fluid goes to the gun). For initial setup, ensure the prime valve is in the 'down' position.

Goal: Understand the main operational controls of the airless sprayer.

What they say

Hide

to make a mess so if you've never used an airless sprayer before what type of knobs or valves or buttons do you have on that thing so we've got our this is our siphon this is our prime hose the little hose that comes out next to the siphon which is the big one and then most sprayers are going to follow the same pattern and they're going to be pretty simple you're going to have your pressure knot or your pressure dial here which is going to bring your pressure up or down you're going to have it's on the back side here so you can't see there's a little uh prime valve and that's going to that that is going to make it so that it either sends fluid through the prime hose or to the gun and for the most part if it's pointed down alongside the the prime hose that's going to be prime and then when you click it up that's going to be spray and then you've got your power so really you've only got three little things on this that you need to worry about power your pressure knob and then your prime valve so let's uh go ahead turn it on right now the prime valve is down so it's on prime you're going to hold on to the prime hose just so it doesn't kick up and then we've got to make sure we've got power which we don't have power so most airless sprayers follow the same rules as far as what they have on them you're going to have your power button or power switch which will be located somewhere on the body here you're going to have your pressure valve or not valve but your pressure dial which is going to adjust your pressure either up or down depending on where you want it and then they're all going to have a prime valve
