Pro Tips for Maximizing GMAX 3400 Sprayer Longevity

Proper maintenance and the right parts go a long way toward avoiding downtime and costly repairs. Here’s how to keep your Graco GMAX 3400 Pump (246428) running strong:

1. Log Service Intervals

Establish a preventive maintenance schedule based on your workload and material types. Regularly inspect wear parts like seals, valves, and filters to avoid surprise failures.

2. Lubricate With Every Rebuild

Apply Graco-recommended lubricant during every pump repair or seal kit installation. This prevents premature wear and extends your pack-out intervals.

3. Stock Critical Components

Keep spare tip guards, filters, and check valves on hand. Having extras ready to go can keep jobs running when failures strike unexpectedly.

4. Organize Parts by Use

Use color-coded bins to store parts like Graco spray gun components, drywall blades, and Graco Paint Sprayer Parts & Accessories. This makes for faster identification and avoids mixing up similar parts between sprayer models.
