Guide to Maintaining Your Graco Paint Sprayer
Flush the System:
After each use, flush the paint sprayer with a water-only solution to remove any excess paint and keep it in good working condition. Ensure no more than two gallons of water is used simultaneously to avoid over-saturating the system.
After use, immediately clean out the nozzle, hose, and cup of your Graco paint sprayer by running cleaning fluid through them. This will help ensure that all parts are free from dried paint buildup or other debris, which could cause clogs or blockages when not removed promptly.
Depending on how long between uses you have let your Graco paint sprayer sit, you may need to soak the parts in a cleaning solution. This will help loosen any dried paint and debris built on them over time. Always make sure to thoroughly rinse off the parts after soaking, or else this could lead to clogs or blockages later.
Brush It Out:
Use a soft brush to clean out the nozzle, hose, and cup of your Graco Paint Sprayer. This will remove any remaining dirt or debris and help prevent the future buildup of unwanted materials. Be sure not to use anything too abrasive, which may damage your Graco Paint Sprayer’s components.
After brushing out all the parts, thoroughly rinse them with warm water. This will help eliminate any remaining dirt or debris and will also help ensure that no cleaning solution residue is left behind.
Dry It Off:
After rinsing, it is vital to ensure all parts are correctly dried off before storing your Graco Paint Sprayer away for future use. This ensures that the parts remain in good condition and prevents any corrosion from occurring.
Clean your Graco Paint Sprayer’s interior using a soft brush and warm water after each use. This helps remove any unwanted paint or particle buildup on the inside walls and keeps your sprayer working in peak condition for a long time.
Depending on how often you use your Graco Paint Sprayer, it will be necessary to periodically replace certain parts, such as the nozzle and hose, to keep your sprayer working optimally. Check for any signs of wear or tear and take appropriate action if necessary.
Clean Between Jobs:
When switching between different types of paint, it is vital to flush out the Graco Paint Sprayer’s system and clean all parts before using a new paint color. This helps avoid mixing colors which could lead to an unexpected shade in the final product.
After cleaning, ensure your Graco Paint Sprayer is stored properly so that no dirt or debris accumulates while it is not in use. This will help keep your sprayer in good condition and ready for the next job.
How To Clean Graco Paint Sprayer
After completing the painting job, cleaning your Graco paint sprayer is essential. Doing this can help ensure your equipment keeps working well and reliably over time. Cleaning your paint sprayer can be relatively simple if you follow the steps below.
1: Pressure Relief Procedure
- Start by turning off the paint sprayer and unplugging it from the power source.
- Release any remaining pressure in the paint sprayer by activating its pressure relief valve near your machine’s rear.
- Activate your pump’s priming knob to remove all residual coating from the hose and gun assembly before disconnecting it from the machine body.
- Remove debris or excess coatings from your airless gun by cleaning it with an appropriate cleaner or solvent. Put aside for further cleaning if needed; otherwise, dispose of it responsibly according to local regulations.
- Disconnect hoses from the gun and sprayer body and place them aside for further cleaning.
2: Flush Coatings
- Reattach the hose to the paint sprayer and secure it with a clamp or similar fastening device.
- Fill your Graco paint sprayer container with an appropriate cleaning solvent, such as mineral spirits or lacquer thinner, depending on the type of coating you use during painting.
- Operate the pump intermittently until all air is cleared from the system and replaced with solvent-filled air.
- Activate your gun’s trigger to release any pressure in the pump and allow its fluid passages to flush cleanly with solvent-filled air expelled from the machine.
- Once the solvent has been completely evacuated, shut down your paint sprayer and turn off its main power switch.
3: Clean The Pump
- Unplug your Graco paint sprayer from any power source and open its hood to access the pump mechanism inside it.
- Remove any debris or excess coatings that have built up around the pump’s inlet valve, piston rod, and seat, using a brush or suitable cleaning tool if necessary.
- Thoroughly rinse away any residues with warm water before wiping down all pump surfaces with a lint-free cloth or similar item for added protection against contamination.
- Reassemble the hood and lid on your paint sprayer once all surfaces have been cleaned, dried, and inspected for any other debris or dirt.
4: Clean the Hose & Gun
- Disconnect the hose from your airless gun and Graco paint sprayer body, then set it aside for further cleaning.
- Flush out the hose with an appropriate cleaner or solvent to remove any residual coatings that may still be present inside it.
- Wipe down the exterior of your airless gun with a lint-free cloth to remove any residue or dirt built up around its nozzle area over time.
- Remove the back cap from your gun and flush its interior with cleaner or solvent, as well as any other components, such as filters, that need cleaning.
- Reattach the hose to the gun and sprayer body once all components have been cleaned and dried.
5: Reassemble & Test
- Reconnect the components of your Graco paint sprayer together and secure them with clamps or other fastening devices as needed.
- Please fill up the machine’s container with an appropriate solvent or cleaner, then operate it to prime its fluid passages and clear out any remaining air bubbles in the system.
- Connect a pressure gauge to the rear of your paint sprayer and check that its pressure output is accurate, meaning it should read around 500 psi (pounds per square inch) when running correctly.
- Multiple times, activate your gun’s trigger to ensure smooth operation without sticking or jerking motions during movement.
- Once all testing is complete and satisfactory, your Graco paint sprayer should be ready. Monitor it closely during operation for any further signs of wear or damage and address them accordingly. Regular cleaning and maintenance are recommended for optimal performance.
