How to Keep Your Graco Paint Sprayer Running Smooth

By Sprayers And Parts 26-08-2025 93

If you’ve ever had a sprayer stop working in the middle of a job, you know how frustrating it is. A Graco sprayer—whether it’s the 395, 490, or 695—is built to last, but it still needs care. A little routine maintenance saves you from wasted time, uneven finishes, and expensive repairs.

This isn’t about fancy tricks. It’s about simple habits that keep your sprayer dependable.

Why Bother with Maintenance?

A paint sprayer is like any other tool: if you ignore it, it won’t perform. Paint dries fast, clogs up filters, wears down piston rods, and hardens inside hoses. Once that happens, pressure drops and the spray pattern goes bad.

Cleaning and checking parts right after each job makes sure your sprayer is ready the next time you pull it out.

Daily Care – What to Do After Each Use

Flush the system – Run clean water or the right solvent until it sprays clear.

Clean the spray gun and tip – Don’t leave paint to dry. Remove the tip guard and wash them properly.

Check filters – Look at pump and gun filters. Replace if they’re clogged.

Wipe the unit down – A quick wipe helps you spot leaks or loose fittings later.

Lubricate moving parts – Use Pump Armor or piston lube to protect seals.

This routine takes less than 15 minutes.
