4. Attach Container: Securely attach the filled container to the sprayer body.
5. Select Nozzle: Choose the appropriate brass nozzle (1.0mm for fine finish, 1.8mm for small interior, 2.5mm for small exterior, 3.0mm for medium exterior) and attach it to the sprayer.
6. Insert Battery: Insert a fully charged Makita 18V battery into the battery slot on the sprayer.

5. Operating Instructions

Once set up, follow these steps for effective painting.

Adjusting Spray Patterns and Flow:

Figure 5.1: Spray pattern and flow control adjustments.

• Spray Size Knob: Rotate the spray size knob to adjust the width of the spray pattern.
• Flow Control Knob: Adjust the flow control knob to regulate the paint output volume.
• 360° Rotating Nozzle: The nozzle can be rotated to achieve horizontal, vertical, or circular spray patterns. Select the pattern best suited for your project.

Spraying Technique:

1. Test Spray: Before painting your main surface, always perform a test spray on a piece of scrap material to ensure the desired pattern and flow.
2. Maintain Distance: Hold the sprayer approximately 6-12 inches (15-30 cm) from the surface, depending on the desired coverage and paint type.
3. Even Strokes: Move the sprayer in smooth, even strokes, overlapping each pass by about 50% to ensure uniform coverage.
4. Release Trigger: Release the trigger at the end of each stroke to avoid paint buildup.
5. Multiple Coats: Apply multiple thin coats rather than one thick coat for a smoother finish and to prevent drips. Allow adequate drying time between coats.

Proper cleaning and maintenance ensure the longevity and optimal performance of your paint sprayer.

After Each Use:

3. Clean Nozzle and Air Cap: Disassemble the nozzle, air cap, and nozzle nut. Clean these parts thoroughly with warm soapy water for water-based paints, or appropriate solvent for oil-based paints. Use the included cleaning brush and valve needle to clear any blockages.
4. Flush Sprayer: Fill a clean cup liner with water (for water-based paints) or appropriate cleaning solvent (for oil-based paints). Attach it to the sprayer and spray until the liquid runs clear.
