Operating Instructions
Power On/Off and Speed Control
The tool features a variable speed trigger. Press the trigger to start the tool; the speed increases as you press the trigger further. The impact wrench offers 4-speed settings, allowing for precise control from 0-1850 RPM. Use the speed selection button, typically located near the battery indicator, to cycle through the different speed modes to match the application requirements.
Forward/Reverse Mode
A directional switch, usually located above the trigger, allows you to select forward (tightening) or reverse (loosening) rotation. Ensure the switch is in the desired position before operating the tool. The tool also features an auto-stop function in reverse mode to prevent over-loosening or accidental ejection of fasteners.

LED Work Light
The integrated LED work light illuminates your work area, providing better visibility in dimly lit or confined spaces. The light activates automatically when the trigger is pressed.
