5. Setup
5.1 Preparing the Paint
The Marietta MPP-700 is compatible with a variety of coatings. Always check the paint manufacturer's instructions for dilution recommendations.
- Water-dilutable paints
- Solvent-soluble varnishes
- Primers (for surface preparation)
- Two-component paints (e.g., epoxy resins)
- Clear enamels (for transparent or semi-transparent finishes)

5.2 Assembling the Sprayer

6. Operation
6.1 Starting the Sprayer
Before starting, ensure you are wearing all necessary protective gear and working in a well-ventilated area. Hold the spray gun firmly and press the trigger to begin spraying.
6.2 Adjusting Spray Pattern
The Marietta MPP-700 offers three spray patterns. To change the pattern, rotate the air cap on the front of the spray gun:
- Circular: For small areas or detailed work.
- Horizontal: For spraying vertical surfaces.
- Vertical: For spraying horizontal surfaces.
6.3 Adjusting Flow Rate
Use the flow adjustment knob located on the spray gun to control the amount of paint being expelled. Turn clockwise to decrease flow and counter-clockwise to increase flow. Start with a lower flow and gradually increase until the desired coverage is achieved.
6.4 Spraying Technique
Maintain a consistent distance (approximately 6-10 inches) from the surface and move the spray gun at a steady speed. Overlap each pass by about 50% to ensure even coverage and avoid streaks or drips. Release the trigger at the end of each pass to prevent overspray.
7. Maintenance
Proper cleaning and maintenance are crucial for the longevity and optimal performance of your paint sprayer.
7.1 Cleaning After Use
- Empty Paint Container: Remove any remaining paint from the container.
- Flush with Cleaning Solution: Fill the container with an appropriate cleaning solution (water for water-based paints, solvent for oil-based paints/varnishes). Spray the solution through the gun until it runs clear.
- Disassemble and Clean: Disassemble the spray gun components (nozzle, air cap, paint container). Clean all parts thoroughly with the cleaning solution and the provided cleaning brush/needle.
- Wipe Down: Wipe the exterior of the main unit and hose with a damp cloth.
- Dry and Store: Ensure all parts are completely dry before reassembling and storing the sprayer in a clean, dry place.
Note: Never immerse the main motor unit in water or cleaning solutions.
