Using the A8 Earth Auger Bit is straightforward. First, make sure your excavator is up to 15 tons, as this bit is designed for such machines. Attach the bit securely to your excavator according to the equipment's instructions. When drilling in earth, aim for a speed between 55 - 65 rotations per minute. For clay, go for 45 - 55 rotations, and for shale, 25 - 45 rotations. Avoid using it on heavy rock as it's not suitable. If you need to replace the teeth, thanks to Digga's unique tooth - locking system, you don't need any complicated tools. Just knock the old teeth out and knock the new ones in. To keep your auger bit in good shape, after each use, clean it thoroughly to remove any dirt or debris. Check the teeth regularly for wear and tear, and replace them when needed. Also, inspect the body of the bit for any signs of damage, especially after use in tough conditions.
