5. Operation

5.1 Power On/Off and Direction Control

The tool features a forward/reverse button and a variable speed trigger.

• To turn the tool ON, press the trigger switch. To turn OFF, release the trigger switch.
• The forward/reverse button (located above the trigger) controls the rotation direction. Push it left for forward (tightening) and right for reverse (loosening).
• A middle position on the forward/reverse button acts as a lock, preventing accidental activation of the trigger.

Figure 5.1: The impact wrench features a forward/reverse selector and a speed gear display. The tool offers different torque levels for various applications.

5.2 Speed Control and Torque Settings

The impact wrench offers three adjustable speed settings and a reverse auto-stop mode.

• Press the speed control button (located on the base of the tool) to cycle through the three speed settings (1, 2, 3). The corresponding indicator lights will illuminate.
• Speed 1: Lower torque for delicate tasks or initial fastening.
• Speed 2: Medium torque for general applications.
• Speed 3: Maximum torque (1850 ft-lbs) for heavy-duty fastening.
• Reverse Auto-Stop Mode: When in reverse, pressing the speed control button activates the auto-stop feature. This mode stops the tool automatically once the fastener is loose, preventing it from falling off completely.
