2. Slide a 20V battery pack onto the charger until it clicks into place.
3. The indicator light on the charger will show the charging status (e.g., red for charging, green for fully charged).
4. Once fully charged, remove the battery from the charger.

4.2 Installing and Removing the Battery

1. To Install: Align the battery pack with the battery interface on the tool. Slide the battery into place until it clicks securely.
2. To Remove: Press the battery release button (usually located on the battery pack) and slide the battery out of the tool.

4.3 Attaching Sockets and Accessories

The AOBEN ratchet wrench is compatible with 3/8" drive sockets. The kit includes various extended sockets, a 3/8" to 1/4" adapter, and a 6-inch extension bar.

1. Select the appropriate socket size for your fastener.
2. Push the socket firmly onto the 3/8" drive square until it locks into place.
3. To use a 1/4" drive socket, first attach the 3/8" to 1/4" adapter to the drive square, then attach the 1/4" socket to the adapter.
4. For extended reach, attach the 6-inch extension bar between the drive square and the socket/adapter.

5. Operating Instructions

5.1 Powering On/Off

1. To Power On: Slide the safety lock switch to the unlocked position. Press the variable speed trigger to activate the tool. The LED work light will illuminate.
2. To Power Off: Release the variable speed trigger. Slide the safety lock switch to the locked position to prevent accidental startup.

5.2 Selecting Direction (Forward/Reverse)

The direction of rotation is controlled by the forward/reverse selector located on the back of the ratchet head.

• For Tightening (Forward): Rotate the selector to the 'F' position (or clockwise direction).
• For Loosening (Reverse): Rotate the selector to the 'R' position (or counter-clockwise direction).

5.3 Applying Torque

The variable speed trigger allows for precise control over the tool's speed and torque output.

1. Ensure the correct socket is securely attached and the direction selector is set appropriately.
2. Position the socket onto the fastener.
3. Gently press the variable speed trigger to start the rotation. The more you press the trigger, the faster the tool will rotate and the more torque it will apply, up to its maximum of 60 ft-lbs.
4. For initial loosening of very tight fasteners, it may be necessary to manually break the fastener loose before using the power ratchet. Similarly, for final tightening, ensure the fastener is adequately secured without overtightening.
