Where is the fluid adjustment mechanism typically located on a spray gun?

The fluid adjustment mechanism on a spray gun is typically located at the rear of the gun. This placement allows the operator to easily adjust the flow of material while maintaining a comfortable grip and steady control over the spraying process. Having the adjustment at the rear helps provide better visibility of the spray pattern and allows for quick and convenient changes without adjusting their stance or hand position significantly.

In contrast, the front or side locations may complicate adjustments during operation, and an underneath placement could restrict access and visibility, making it less practical for the user. Therefore, having the fluid adjustment at the rear enhances operational efficiency and user comfort, which is critical in achieving a consistent and quality finish in painting and refinishing tasks.
