Setup

- Slide the battery into the tool until it clicks securely into place.
- To remove, press the battery release latch and pull the battery out.

Attaching Sockets and Adapters
- Ensure the tool is off and the battery is removed.
- For 1/2-inch square drive sockets: Push the socket firmly onto the square drive anvil until the locking pin engages the hole in the socket.
- For 1/4-inch hex bits: Insert the included 1/4-inch hex adapter onto the 1/2-inch square drive anvil, then insert the hex bit into the adapter.
- To remove, pull the socket or adapter firmly off the anvil while depressing the locking pin if necessary.
Operating Instructions
Powering On/Off and Speed Selection
- To Power On: Squeeze the trigger switch. The tool will begin to rotate.
- To Power Off: Release the trigger switch.
- Direction of Rotation: Use the forward/reverse selector switch located above the trigger to choose between forward (tightening) and reverse (loosening) rotation. Ensure the switch is fully engaged in the desired direction.
- Speed Selection: The tool features a 3-speed selector switch, typically located on the top of the tool. Adjust this switch to select the appropriate speed (and corresponding torque) for your application. Lower speeds provide more control, while higher speeds deliver maximum torque.
Using the Impact Wrench
The impact wrench is designed for fastening and loosening nuts, bolts, and other fasteners. Its impact mechanism delivers high torque with minimal reactive torque to the user.
- Select the appropriate socket or adapter for the fastener.
- Attach the socket/adapter to the tool's anvil.
- Select the desired direction of rotation (forward for tightening, reverse for loosening).
- Choose the appropriate speed setting based on the fastener's tightness and material.
- Place the socket firmly onto the fastener.
- Squeeze the trigger to operate the tool. Apply steady pressure to keep the socket engaged with the fastener.
- For tightening, stop when the fastener is snug. For critical applications, always use a torque wrench for final tightening to specified torque values.


Maintenance
Regular maintenance ensures the longevity and optimal performance of your impact wrench.
- Cleaning: Keep the tool's air vents clear and free of debris. Use a clean, dry cloth to wipe down the housing. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the tool in a dry, secure location out of reach of children. Remove the battery pack when storing for extended periods.
- Inspection: Periodically inspect the tool for any signs of damage, loose screws, or worn parts. Do not use a damaged tool.
