5. Configuració
5.1 Càrrega de la bateria

- Feu lliscar la bateria al carregador fins que encaixi al seu lloc.
- Allow the battery to charge fully before first use. The indicator light on the charger will show charging status.
5.2 Attaching the Container and Battery
- Ensure the paint container is empty and clean.
- Screw the paint container onto the sprayer body until it is securely fastened.
- Slide the fully charged battery into the battery slot on the handle until it clicks into place.
5.3 Nozzle Selection and Installation
The sprayer comes with 5 copper nozzles of different sizes (1.0mm, 1.5mm, 1.8mm, 2.0mm, 2.5mm). Choose the appropriate nozzle based on the viscosity of your paint and desired spray pattern.

- Unscrew the air cap and nozzle ring from the front of the sprayer.
- Insert the chosen nozzle into the nozzle seat.
- Place the air cap over the nozzle and secure it with the nozzle ring, tightening firmly.
5.4 Paint Preparation (Thinning and Filtering)
Proper paint preparation is crucial for optimal spray performance and to prevent clogging. Always refer to the paint manufacturer's instructions for thinning recommendations.

- Pour paint into the provided viscosity measuring cup.
- Time how long it takes for the paint to completely drain from the cup. Refer to the paint thinning guide (if available) or paint manufacturer's recommendations for ideal run-out times.
- If the paint is too thick, add the recommended thinner (e.g., water for latex, mineral spirits for oil-based) gradually and mix thoroughly. Re-test viscosity until desired consistency is achieved.
- Filter the thinned paint through a paint strainer or filter paper to remove any lumps or debris that could clog the sprayer.
- Pour the prepared paint into the sprayer's container.
6. Instruccions de funcionament
6.1 Ajust del patró de polvorització
The sprayer offers three adjustable spray patterns: horizontal, vertical, and circular (dot). Rotate the air cap to select the desired pattern.

- Horizontal (180°): Ideal for spraying vertical surfaces like fences or walls.
- Vertical (90°): Suitable for spraying horizontal surfaces like decks or tabletops.
- Circular (45° Dot): Best for small areas, edges, or corners.
6.2 Adjusting Paint Flow
The flow adjustment key (located near the trigger) controls the amount of paint sprayed. Turn it clockwise to increase flow and counter-clockwise to decrease flow. Start with a lower setting and gradually increase until the desired coverage is achieved.
6.3 Tècnica de polvorització
- Before spraying your actual project, test the spray pattern and flow on a piece of scrap material (e.g., cardboard) to ensure proper settings.
- Hold the sprayer approximately 6-12 inches (15-30 cm) from the surface, depending on the desired coverage and paint type.
- Move the sprayer in smooth, even strokes, overlapping each pass by about 50% to ensure uniform coverage.
- Release the trigger at the end of each stroke to avoid paint buildup.
- Apply multiple thin coats rather than one thick coat to prevent drips and achieve a smoother finish.

7. Manteniment
Regular cleaning and maintenance will prolong the life of your paint sprayer and ensure consistent performance.
