4. Use Guide

4.1 Initial Setup

1. Charging the Batteries: Insert the battery into the provided fast charger. The charger indicator will show the charging status. A full charge takes approximately 30 minutes to reach 80% capacity.
2. Installing the Battery: Slide a charged battery into the battery port on the tool until it clicks into place.
3. Attaching a Socket: Pull back the Hog Ring on the anvil, insert the square drive of the socket, and release the ring to lock the socket in place.

4.2 Basic Operation

1. Power On/Off: The tool is activated by pressing the variable-speed trigger. Release the trigger to stop.
2. Selecting Direction: Use the forward/reverse switch located above the trigger.
   • Push the switch to the left (⭯ symbol) for forward (tightening) rotation.
   • Push the switch to the right (⭮ symbol) for reverse (loosening) rotation.
3. Selecting Speed Gear: Rotate the gear selection dial (numbered 1, 2, 3) to choose the appropriate speed and power level for your task.
4. Using the LED Light: The LED work light turns on automatically when the trigger is pressed. It cannot be manually turned on independently.

4.3 Performing Tasks

• Loosening a Bolt/Nut: Set the direction switch to reverse (⭮). Place the socket securely on the fastener. Press the trigger firmly. The impact mechanism will deliver concussive force to break the fastener free.
• Tightening a Bolt/Nut: Set the direction switch to forward (⭯). Start the tool at a low speed to thread the fastener. Increase pressure on the trigger to apply final torque. Caution: Do not over-tighten, as this can damage threads or the fastener.
• For Precision Work: Use Gear 1 and apply light pressure to the variable-speed trigger for better control.

4.4 Battery and Charging

• The 3-LED battery indicator on the tool shows remaining charge. Press the battery check button to illuminate the LEDs.
  • 3 LEDs: High charge (60-100%)
  • 2 LEDs: Medium charge (30-60%)
  • 1 LED: Low charge (10-30%)
  • Flashing LED: Charge immediately (<10%)
• For optimal battery life, avoid completely draining the batteries. Recharge when the indicator shows one LED.
• Store batteries in a cool, dry place away from metal objects.

5. Maintenance and Storage

• Keep the tool clean. Wipe the exterior with a dry cloth. Do not use solvents or immerse the tool in liquid.
• Periodically check the Hog Ring Anvil for wear or damage.
• Store the tool and batteries in the provided case in a dry location.
• The tool has an internal cooling fan. Keep the air vents clear of debris.
• The tool features smart protection against over-current, over-voltage, overheating, and short circuits. If the tool stops unexpectedly, allow it to cool down and check the battery charge.
