Dress properly; avoid loose clothing or jewelry. Keep hair, clothing, and gloves away from moving parts.
- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
- Battery Tool Use and Care: Recharge only with the charger specified by the manufacturer. Use power tools only with specifically designated battery packs.

| Problem | Possible Cause | Solution |
|---|---|---|
| Tool does not start | Battery not inserted correctly or discharged. | Ensure battery is fully inserted. Charge battery if necessary. |
| Reduced power or torque | Battery low or incorrect impact mode selected. | Recharge battery. Select a higher impact mode. |

9. User Tips
- Battery Compatibility: Remember that this impact wrench is sold without a battery. You will need a compatible Makita 18V LXT battery and charger to operate it.
- Impact Regulation: The tool features multiple impact regulation settings (Strong/High/Medium/Low). Experiment with these settings to find the optimal power for different bolt sizes and materials, preventing overtightening or stripping.
- Socket Selection: Always use impact-rated sockets with your impact wrench. Standard sockets are not designed to withstand the high torque and impact forces and can shatter, causing injury.
- Workpiece Stability: Ensure the workpiece is securely clamped or supported to prevent movement during operation, which can lead to inaccurate fastening and potential injury.
