Adjusting Controls

• Pattern Control Knob: Located at the rear of the gun, this knob adjusts the spray pattern from a full, wide fan to a round, concentrated spray.
• Fluid Control Knob: This knob regulates the amount of paint mixed with air. Turn clockwise to decrease fluid flow, counter-clockwise to increase.
• Air Control Knob: Adjusts the overall air flow. Turn clockwise to decrease air flow, counter-clockwise to increase.
• Air Cap Ring: Rotate the air cap ring at the end of the nozzle to adjust the direction of the spray fan (vertical for side-to-side spraying, horizontal for top-to-bottom spraying).

Spraying Technique

1. Hold the spray gun approximately 6-8 inches from the surface.
2. Press the trigger to the first step to initiate air flow.
3. Press the trigger further to engage paint flow.
4. Move the gun in smooth, even passes, overlapping each pass by about 50%.
5. Release the trigger at the end of each pass to avoid paint buildup.
