Adjusting the spray pattern of a siphon air spray gun allows you to control the coverage and direction of the paint. Follow these steps to adjust the spray pattern:
1. Ensure the gun is disconnected from the air supply.
2. Locate the pattern control knob or dial on the gun.
3. Turn the knob or dial clockwise to narrow the spray pattern or counterclockwise to widen it.
4. Test the spray pattern on a test surface and make further adjustments if needed.
5. Once satisfied with the spray pattern, reattach the gun to the air supply and continue painting.
