4. Setup
Before initial use, ensure all components are present and undamaged.
- Unpacking: Carefully remove the sprayer and all accessories from the packaging.
- Assembly: Attach the high-pressure hose to the sprayer outlet and the spray gun. Ensure all connections are tight.
- Tip Installation: Install the appropriate spray tip for your material and application into the spray gun.
- Material Preparation: Stir your paint or coating thoroughly. For optimal performance, strain the material to remove any lumps or debris.
- Priming: Place the suction tube into the paint container and the drain tube into a waste bucket. Turn the prime/spray valve to the prime position. Turn on the sprayer and allow it to run until paint flows smoothly from the drain tube, indicating the pump is primed.
- Kickstand Use (Hi-Boy models): Utilize the integrated kickstand for stable positioning and easy one-person bucket changes.
5. Operating Instructions
Proper operation ensures a quality finish and extends the life of your sprayer.
- Pressure Adjustment: Turn the prime/spray valve to the spray position. Use the SmartControl 3.0 interface to set the desired pressure. Start with a lower pressure and gradually increase until you achieve a consistent spray pattern without tails.
- Spraying Technique: Maintain a consistent distance (typically 10-12 inches) from the surface. Move the spray gun in smooth, overlapping passes. Release the trigger at the end of each pass to prevent excessive build-up.
- Material Changes: When changing materials or colors, thoroughly clean the sprayer as described in the Maintenance section.
- Shutting Down: When finished spraying, turn off the sprayer, relieve pressure by engaging the gun safety lock and then pulling the trigger into a waste bucket, and then turn the prime/spray valve to the prime position.
