5. Operation
5.1 Priming the Sprayer
Before first use and after each cleaning, the sprayer must be primed to remove air from the system and ensure proper paint flow.
- Place the suction tube into a bucket of water or thinner (depending on paint type).
- Turn the pressure control knob to the 'Prime/Slow' setting.
- Turn on the power switch.
- Open the return valve to allow water/thinner to circulate through the system until a steady stream emerges from the return pipe.
- Close the return valve and turn the pressure control knob to the desired spray pressure.
5.2 Spraying Techniques
For optimal results, maintain a consistent distance and angle from the surface. Overlap each pass by approximately 50% to ensure even coverage. The sprayer offers adjustable pressure settings to meet different spraying needs:
- Low Gear: Ideal for fine painting and detailed work.
- Medium Gear: Suitable for general painting tasks.
- High Gear: For fast painting and large surfaces.
