???? Pro-Level Tips for Long-Lasting Performance

Stay ahead of the maintenance curve with these contractor-tested best practices:

1. Schedule Preventative Rebuilds
   Replace pistons and packings after every 500–700 gallons—or sooner for abrasive coatings.

2. Always Use Graco-Approved Lubricants
   Packings need TSL or lithium grease during rebuild to prevent wear.

3. Flush After Every Job
   Use compatible solvents to clear residue from high-viscous coatings and preserve component life.

4. Stock Spare Pump Sections
   Keep a spare GMax 3900 fluid section or pump kit for fast field replacement.

5. Organize by O-Ring & Seal Size
   Use labeled bins for o-rings, valves, and packings to avoid sci-fi scavenger hunts on site.
