Setup

1. Battery Installation: Ensure the impact wrench is switched off. Align the compatible 18V Makita-style battery (not included) with the battery slot at the base of the tool. Slide the battery firmly until it clicks into place. To remove, press the battery release button and slide the battery out.
2. Accessory Attachment: Select the appropriate 1/2" square drive socket or accessory for your task. Push the accessory onto the square drive until it is securely seated.

Operating Instructions

1. Power On/Off: Press the main power button (if present) or simply press the trigger to activate the tool.
2. Selecting Rotation Direction: Use the Forward/Reverse switch located near the trigger to select the desired rotation direction. Ensure the switch is fully engaged in either forward or reverse position, not in the center (locked) position.
3. Speed Control (Automatic Transmission): The tool features an automatic transmission system. The speed of the wrench is directly proportional to the pressure applied to the trigger. Gently pressing the trigger will result in low speed, while pressing it fully will achieve high speed. The 5-gear system allows for precise control.
4. LED Work Light: The integrated LED work light automatically illuminates when the trigger is pressed, providing visibility in dimly lit areas.
5. Reverse Rotation Auto-Stop Mode: When operating in reverse (counterclockwise), this mode stops the impact and rotation within 0.1-0.2 seconds after the bolt/nut is sufficiently loosened. This prevents over-loosening and dropping fasteners.
6. Application: Position the tool with the attached socket firmly onto the fastener. Apply steady pressure and press the trigger to begin operation.

Maintenance

• Cleaning: Regularly clean the tool's exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Brushless Motor: The brushless motor design reduces wear and tear, requiring less maintenance compared to brushed motors. However, keep the cooling vents clear of debris to ensure proper airflow.
• Storage: Store the tool in a dry, clean place away from direct sunlight and extreme temperatures. Remove the battery if storing for extended periods.
• Inspection: Periodically inspect the tool for any signs of damage, loose parts, or wear. If any issues are found, discontinue use and contact customer support.

Troubleshooting

• Tool Not Starting:
  • Ensure the battery is fully charged and correctly installed.
  • Check the Forward/Reverse switch is not in the center (locked) position.
• Reduced Power/Performance:
  • The battery may be low on charge. Recharge the battery.
  • Ensure the correct socket size is being used and it is properly seated.
• Overheating:
  • Check that the cooling holes are not obstructed.
  • Allow the tool to cool down before resuming operation. Avoid continuous heavy-duty use without breaks.

User Tips

• Battery Selection: This impact wrench is designed for Makita 18V B-series lithium batteries. Ensure you use compatible batteries for optimal performance and safety. G-series or Ni-CD batteries are NOT compatible.
• Fastener Size: The tool is suitable for standard bolts M10-M20 (3/8"-3/4") and high-strength bolts M10-M16 (3/8"-5/8"). Using it outside these ranges may affect performance or damage the tool/fastener.
• Trigger Control: Utilize the stepless speed change by varying your trigger pressure. This allows for precise control, especially when starting to tighten or loosen fasteners, preventing stripping or over-tightening.
