Pro Tips for Long-Term Reliability
Keeping your Graco 455 ST Pro Hi-Boy sprayer in top shape doesn’t require a lot of time—it just takes the right practices. Here are expert-backed recommendations to help you maximize equipment life:
Track Usage and Schedule Maintenance
Create a simple log of operating hours and coating types used. Replace packings, valves, filters, and seals on schedule—not after failure.
Always Lube New Seal Kits
Graco seal kits are designed for extended life, but they still require proper lubrication during installation. Use OEM-recommended lubricant to avoid dry starts and premature wear.
Stock Spare Components
When deadlines are tight, you don’t want to be caught without a critical part. Keep extras of common wear items like inlet strainers, piston rods, and prime valves in your jobsite kit or van.
Organize Parts for Quick Access
Set up color-coded bins or compartments for related components like Graco airless sprayer accessories, extension tools, and gun rebuild kits. This makes on-site maintenance or last-minute repairs faster and error-free.
