Operating Instructions
- Prime the Sprayer: Follow the manufacturer's instructions for priming the pump to remove air from the system. This typically involves setting the prime/spray valve to "prime" and running the unit until material flows smoothly.
- Adjust Pressure: Set the desired spray pressure using the adjustable control. Start with a lower pressure and gradually increase until the desired spray pattern is achieved.
- Test Spray: Before spraying your project, test the spray pattern on a piece of scrap material. Adjust pressure and technique as needed.
- Begin Spraying: Maintain a consistent distance and speed from the surface. Overlap each pass by approximately 50% for even coverage.
- Stop Spraying: Release the trigger to stop the flow of material.
Maintenance
Cleaning After Use:
- Relieve Pressure: Always relieve system pressure before cleaning or performing any maintenance.
- Flush System: Use the quick-flush adapter connected to a garden hose to thoroughly flush the system with water (for water-based materials) or appropriate cleaning solution (for oil-based materials).
- Clean Components: Clean the spray gun, tip, and suction tube separately.
- Apply Storage Fluid: After cleaning, run 4 oz. of storage fluid through the pump to protect internal components during storage.
Pump Replacement:
The pump is designed for easy replacement, typically in under one minute. Refer to the detailed pump replacement guide (if provided separately) or contact customer support for assistance.
Piston Lube Oil:
Regularly apply piston lube oil (8 oz. provided) to the piston rod as directed to ensure smooth operation and extend pump life.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No spray or weak spray | Clogged tip, air in system, low material, pump issue | Clean tip, re-prime sprayer, refill material, check pump |
| Inconsistent spray pattern | Incorrect pressure, worn tip, material too thick | Adjust pressure, replace tip, ensure material is suitable for spraying |
| Leaks | Loose connections, damaged seals | Tighten connections, inspect and replace seals |
| Motor runs but no pressure | Inlet valve stuck, pump not primed | Clean inlet valve, re-prime pump |
