Prepare the Cleaning Solution

Fill a clean bucket or other containers with warm water and Graco 390 cleaner according to the instructions on the bottle. Mix until thoroughly combined.

Once you have finished wiping away all residue, rinse off your paint sprayer with clean water and dry it thoroughly with another cloth or paper towel.

Clean Interior Components

To get the interior components of your paint sprayer clean, use a soft-bristled brush or compressed air to remove excess dirt or dust that has built up over time.

How To Assemble the Graco 390 Paint Sprayer?

Graco 390 paint sprayers are an excellent choice for home renovation projects. But before you start your project, you must assemble the sprayer correctly. Here’s what you need to do:

Unpack the Contents:

Carefully remove the Graco 390 paint sprayer and all components from their packaging. Be sure to check that you have all of the pieces before proceeding with assembly.

Attach the Hose Fittings:

Attach the hose fittings by pushing them into the designated gun handle and sprayer body locations. Tighten any screws that may be necessary, but be careful not to over-tighten.

Connect the Air Supply Hose:

Connect one end of your air supply hose to your compressor and thread it through your Graco 390’s gun handle until it reaches its connection point on the sprayer body. Connect the other end of the hose to the connection point and hand-tighten it as necessary.

Install the Gun Filter:

The gun filter should be attached to the gun handle, just below the air supply connection point. This will help prevent debris and particles from getting into your paint sprayer system and clogging it up.

Attach the Spray Tip:

Attach the appropriate size spray tip by unscrewing the collar on top of the gun handle, inserting your chosen tip, and tightening up both sides of the collar securely with a wrench or similar tool.

Fill With Paint:

Finally, fill your Graco 390 paint sprayer with the paint of your choice, and you’re ready to go!

Now that you know how to assemble the Graco paint sprayer, it’s time to start spray painting! Be sure to follow all safety instructions when using any paint sprayer. And always wear protective gloves and eyewear, as well as a respiratory mask if recommended, for your safety. Happy Painting!
