7. Troubleshooting

This section addresses common issues you might encounter with your Avhrit Cordless Impact Wrench.

7.1 Socket Not Holding Torque / Excessive Wobble

If the socket appears to wobble excessively or the tool struggles to apply sufficient torque, ensure the socket is fully seated on the anvil. Verify that the retaining ball on the anvil is properly engaging the socket. If the issue persists, inspect the anvil for any signs of wear or damage. Worn anvils can reduce torque transfer and may require replacement.

7.2 Battery Dislodging During Use

If the battery frequently dislodges from the tool during operation, check the battery release mechanism and the battery slot for any obstructions or damage. Ensure the battery is fully inserted and clicks securely into place. If the issue continues, the battery or tool's battery interface may be faulty.

7.3 General Power Issues

• Tool not turning on: Ensure the battery is fully charged and properly inserted. Check if the forward/reverse switch is in the middle (safe) position.
• Reduced power: The battery might be low on charge. Recharge the battery. If the issue persists, the battery may be at the end of its lifespan.
