1.Keep the tool clean, remove dirt, wood resin, and other impurities. Use standard industrial solvents for cleaning.

2.Apply a small amount of oil to prevent rust and damage to the tool surface. Clean all stains on the tool shank to prevent slippage during operation.

3.Do not re-grind the tool or change the shape of the tool, as every grinding process requires professional equipment and professional grinding techniques, otherwise it will cause edge fracture and industrial accidents.
