4. Setup
4.1. Battery Charging
To charge the battery:
- Plug the EU charger into an appropriate AC outlet.
- Insert the battery pack firmly into the charger.
- The charging lamp will light up during charging.
- When charging is complete, the charging lamp will start flashing quickly.
- If the battery pack is warm (e.g., immediately after heavy use), charging will not occur until the battery cools down. The orange standby lamp will light until the battery is cool, then charging will begin automatically.
- For new battery packs or those unused for a prolonged time, charge for approximately 24 hours to reach full capacity.
Charging Indicator Light Status:
| Charge State | Indicator State |
|---|---|
| Charger Into The Power Source | Green on, Red off |
| Charging | Green off, Red on |
| After Charging | Green on, Red off |
| Battery Abnormal | Green Red Flick |
| Battery Temperature Below 0°C or Over 45°C | Green off, Red Flick |
Note: The plug defaults to EU. If you require other specifications (US, UK, AU), please contact customer service for a conversion head (for orders from China warehouse only).

5. Operation
5.1. Using the Control Switch (Forward/Reverse/Lock)
The control switch has three positions: forward (clockwise), reverse (counter-clockwise), and lock. It can only be adjusted when the ON/OFF trigger is not pressed. Always allow the motor to come to a complete stop before adjusting the control switch.
- For Forward (Clockwise) Rotation: Push the control switch in the direction indicated for forward operation.
- For Reverse (Counter-Clockwise) Rotation: Push the control switch in the direction indicated for reverse operation.
- To Lock the Trigger: Push the control switch to the center position. The trigger will not function when locked.

5.2. Starting, Stopping, and Controlling Speed
This tool can be operated at any speed from 0 to full speed.
- To Start: Pull the trigger. An LED light will turn on.
- To Vary Speed: Increase or decrease pressure on the trigger. The further the trigger is pulled, the greater the speed.
- To Stop: Release the trigger. The electric brake will stop the tool instantly.

5.3. Impacting Techniques
- The longer a bolt, screw, or nut is impacted, the tighter it will become. Avoid excessive impacting to prevent damage to fasteners or workpieces.
- Be particularly careful with smaller fasteners, as they require less impacting to reach optimum torque.
- Practice with various fasteners to understand the time required for desired torque. Check tightness with a hand-torque wrench. Adjust impacting time as needed.
- Oil, dirt, rust, or other matter on threads or under the fastener head can affect tightness.
- The torque required to loosen a fastener is typically 75% to 80% of the tightening torque, depending on surface conditions.
- For light gasket jobs, run each fastener down to a relatively light torque and use a hand torque wrench for final tightening.
5.4. Reverse Auto-Stop Function
The wrench includes a reverse auto-stop function to prevent nuts from falling off after loosening. This function automatically stops the tool when turning to the edge of the bolt in reverse mode.

6. Maintenance
- Keep the wrench clean. Use a clean cloth to wipe down the tool, battery, and charger. Do not use abrasive or solvent-based cleaning agents.
- Use a soft brush or dry cloth to clean dust from the wrench head.
- Do not immerse the wrench, battery, or charger in any liquid.
- Regularly inspect the tool for any signs of damage or wear. If any damage is found, discontinue use and seek professional repair.
- Store the tool in a dry, secure place, out of reach of children.
7. Troubleshooting
7.1. Tool Not Starting
- Ensure the battery pack is fully charged and properly inserted.
- Check that the control switch is not in the locked (center) position.
- Verify that the ON/OFF trigger is being pulled sufficiently.
7.2. Reduced Power or Performance
- Check the battery indicator light; recharge the battery if low.
- Ensure the correct size and type of socket is being used for the fastener.
- Clean any debris from the square drive and socket.
7.3. Battery Not Charging
- Ensure the charger is properly plugged into a working AC outlet.
- Check the charging indicator light for error codes (e.g., Green Red Flick for abnormal battery, Green off Red Flick for temperature issues).
- Allow a warm battery to cool down before attempting to charge.
