After you’ve unboxed and familiarized yourself with the paint sprayer, it’s time to move on to assembling the components and getting everything ready for your painting project.
Assembling the Components of the Paint Sprayer
To start the process, you’ll need to put together all the different parts of the sprayer. Here are some assembling tips to help you out:
- Make sure to read the instruction manual carefully before starting.
- Lay out all the components on a clean and flat surface.
- Attach the handle to the sprayer body using the provided screws and a screwdriver.
- Connect the hose to the sprayer by twisting it clockwise until it locks into place.

By following these steps, you’ll have your Graco 390 Airless Paint Sprayer ready to go. If you encounter any issues during assembly, refer to the troubleshooting tips in the manual. Once assembled, you can move on to preparing the surface and paint for spraying.
Preparing the Surface and Paint for Spraying
To prepare the surface for spraying, follow these steps:
-
Clean the surface thoroughly by removing any dirt, dust, or debris. Use a mild detergent and water, and scrub with a brush or sponge. Rinse the surface with clean water and allow it to dry completely before painting.
-
Choose the right paint for your project. Consider the type of surface you are painting and the desired finish. Ensure the paint is compatible with your Graco 390 airless paint sprayer.
-
Adjust the spray settings for desired coverage. This includes adjusting the pressure, spray pattern, and flow rate of the paint sprayer. Test the settings on a small area before spraying the entire surface.
Remember, proper surface preparation and paint selection are key to achieving a flawless finish. Take your time and follow these steps to ensure a successful spray painting project.
Adjusting the Spray Settings for Desired Coverage
Ensure you have the perfect coverage by adjusting the spray settings on your Graco 390. To adjust the spray pattern, locate the spray tip guard and turn it clockwise or counterclockwise to change the fan width. A narrow fan width will provide more concentrated coverage, while a wider fan width will cover a larger area.
Additionally, you can adjust the pressure control knob to increase or decrease the paint flow. If you encounter a clogged nozzle, first, make sure the sprayer is turned off, then remove the nozzle and clean it with a nozzle cleaning tool or a small brush. Reattach the nozzle and test the spray pattern to ensure it is clear and even.
Now that you have adjusted the spray settings, you are ready to move on to starting and stopping the paint sprayer, ensuring seamless application.
Starting and Stopping the Paint Sprayer
Starting and stopping the paint sprayer is a seamless process once you’ve mastered adjusting the spray settings. This allows for effortless application.
To start the Graco 390 airless paint sprayer, simply turn on the power switch and squeeze the spray gun trigger. The sprayer will begin pumping paint through the hose and out of the nozzle.
If you’re experiencing any issues with starting, make sure the power source is connected and the spray gun is properly primed. If the motor doesn’t start, check the fuse and replace if necessary.
To stop the sprayer, release the spray gun trigger and turn off the power switch. This will stop the pump and prevent any paint from being sprayed.
Now, let’s move on to cleaning the paint sprayer after use and ensuring its longevity.
Cleaning the Paint Sprayer After Use
After you’ve finished using the paint sprayer, it’s time to give it a thorough cleaning to ensure optimal performance for future projects.
Cleaning the paint sprayer involves a few key techniques. First, remove any remaining paint from the sprayer by spraying a cleaning solution through the nozzle and into a waste container.
Next, disassemble the paint sprayer and clean each part individually. Use a brush and solvent to remove any dried paint or debris. Pay special attention to the filters, as they can easily become clogged.
Once all the parts are clean, reassemble the sprayer and run clean water through it to flush out any remaining residue. It’s important to use the best cleaning products recommended by Graco to ensure the longevity of your sprayer.
With the sprayer clean and ready for the next job, it’s time to move on to disassembling and cleaning the spray gun.
Disassembling and Cleaning the Spray Gun
To properly maintain your spray gun and ensure its longevity, it’s crucial to disassemble and thoroughly clean it after each use.
The disassembling process involves removing the spray tip, guard, and filter from the gun. Carefully unscrew the tip using a wrench, then detach the guard by unscrewing the retaining nut.
Next, remove the filter from the gun handle. Once disassembled, clean each part separately. Use a brush and solvent to remove any paint residue from the spray tip and guard. For the filter, rinse it with warm soapy water until clean.
Dry all parts thoroughly before reassembling the spray gun. With the gun disassembled and cleaned, you can now move on to the next step of flushing the paint sprayer system, which ensures a clean and efficient operation.
Flushing the Paint Sprayer System
Now that we’ve disassembled and cleaned the spray gun, let’s move on to the exciting step of giving our paint sprayer system a refreshing flush. Proper paint sprayer maintenance includes regular cleaning, as it helps to maintain the performance and longevity of the equipment. Flushing the paint sprayer system removes any leftover paint or debris, preventing clogs and ensuring a smooth spraying process. To flush the system, follow these steps:
