5. Operating Instructions

5.1. Powering On/Off

The tool is powered on by pressing the variable speed trigger and powered off by releasing it.

5.2. Selecting Rotation Direction (Forward/Reverse)

The forward/reverse switch is located above the trigger. Push the switch to the left for forward rotation (fastening) and to the right for reverse rotation (loosening). Ensure the switch is in the center position to lock the trigger and prevent accidental starting.

5.3. Variable Speed Control

The tool's speed is controlled by the pressure applied to the trigger. Pressing the trigger lightly results in lower speed, while pressing it fully increases the speed up to the maximum. This allows for precise control depending on the task.

  2. Set the forward/reverse switch to the desired direction.
  3. Place the socket onto the fastener.
  4. Gradually press the trigger to start the tool. Apply steady pressure to the tool to prevent kickback.
  5. For fastening, tighten until the desired torque is achieved. For loosening, continue until the fastener is free.

Caution: Always ensure the fastener and socket are correctly aligned to prevent damage to both the tool and the fastener.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your impact wrench.

  • Cleaning: Keep the tool's ventilation openings clean to prevent overheating. Use a soft, damp cloth to clean the housing. Do not use harsh chemicals or abrasive cleaners.
