- Slide the M12 REDLITHIUM battery pack into the charger. Ensure it is fully seated.
- The charger's indicator light will change to indicate charging status (e.g., solid red for charging, solid green for fully charged).
- Once fully charged, remove the battery pack from the charger.
4.2 Installing/Removing the Battery Pack
- Installation: Align the battery pack with the base of the impact wrench. Slide the battery pack into the tool until it clicks securely into place.
- Removal: Press the battery release button located on the battery pack. Pull the battery pack out of the tool.
4.3 Attaching Sockets
The impact wrench features a 1/2" square drive with a friction ring for secure socket retention.
- Select the appropriate 1/2" drive impact-rated socket for your application.
- Push the socket firmly onto the anvil of the impact wrench until it snaps into place. The friction ring will hold the socket securely.
- To remove, simply pull the socket off the anvil.
5. Operating Instructions
5.1 Forward/Reverse Control
The forward/reverse lever is located above the trigger. Push the lever to the left for forward rotation (tightening) and to the right for reverse rotation (loosening). Position the lever in the center for the trigger lock, which prevents accidental activation.

5.2 4-Mode DRIVE CONTROL™
The impact wrench features a 4-Mode DRIVE CONTROL system, allowing you to select the appropriate speed and power for various applications. This includes an Auto Shut-Off mode and a Bolt Removal mode.
- Mode 1: Low power for delicate applications or when precise control is needed.
- Mode 2: Medium power for general fastening tasks.
- Mode 3: Full power for maximum torque applications.
- Mode 4 (Auto Shut-Off/Bolt Removal): This mode is designed to prevent over-tightening in forward and provides controlled bolt removal in reverse. In forward, it stops the tool once it senses the fastener is seated, preventing over-tightening. In reverse, it slows down the tool once the fastener is broken loose, preventing fastener run-off.
5.3 How to Change Modes
To cycle through the DRIVE CONTROL modes:
- Ensure the forward/reverse lever is set to the neutral (center) position.
- Pull the trigger twice in quick succession. The mode indicator lights on the tool will change to reflect the selected mode.
Figure 5.2: Steps for changing DRIVE CONTROL modes.
5.4 General Usage Tips
- Always ensure the battery is fully charged before starting a task.
- Select the appropriate mode for the task to prevent damage to fasteners or the workpiece.
- For maximum torque, ensure the tool is held firmly and squarely against the fastener.
- The integrated TRI-LED worklight illuminates the work area for improved visibility.
