What should you do if the material control valve does not limit the trigger from opening fully?

If the material control valve does not limit the trigger from opening fully, turning the valve in or clockwise is the appropriate action. This adjustment is essential because it can help regulate the flow of material more effectively, ensuring that the application process is controlled and prevents over-spray, which can lead to a poor finish and waste of materials. The adjustment allows for fine-tuning of the valve to achieve the desired performance, balancing flow rates while maintaining optimal spraying conditions.

Making this adjustment is crucial for painting and refinishing tasks as it can greatly influence the quality of the finish and the efficiency of the process. The ability to control the trigger and, by extension, the material flow ensures that the painter can achieve precise results while minimizing the risk of defects in the final application.
