Pro Tips for Extending Sprayer Life & Maximizing Performance

Even a machine as rugged as the Graco GMAXII 7900 HD IronMan Series needs regular care. Here’s how the pros keep theirs running like new:

Log Service Intervals
Use a service log to track when seals, filters, and valves were last changed. This helps prevent emergency failures on the jobsite.
Use Lubricant with Every Seal Kit
Graco Throat Seal Liquid (TSL) prevents premature wear and keeps packings from drying out during storage.
Keep Spare Parts on Hand
Stock extras like Graco 395 PC parts, tips, and filters in color-coded bins to avoid confusion and downtime.
Clean After Every Use
Especially important with solvent-based or elastomeric coatings—failure to clean components leads to hardened material that damages internal parts.

By following these tips and using only genuine Graco parts, your 7900 HD IronMan Series sprayer will deliver reliable, high-output performance for years.
