How to fix a chipped saw blade:
1. When manually feeding wood, always keep the wood close to the workbench and the positioning plate. Keep your hands away from the saw blade. Never work on wood that you cannot control.
2. Before working on the wood, check the wood for nails, sand, gravel, or loose knots to prevent damage to the saw blade or flying knots that could injure someone.
3. No one should stand in the cutting direction. Operators should also pay attention to safety when collecting wood.
4. Always disconnect the power supply before cleaning the machine, applying lubricant, replacing the saw blade, or removing wood chips.
5. If a malfunction occurs, immediately disconnect the power supply and stop operations. Have a dedicated technician perform repairs and adjustments. The machine should never be operated with a malfunction.
6. Before starting the machine, carefully check the blade washer, compression nut, and all screws to ensure they are secure. Tighten any looseness immediately. When installing the saw blade, pay attention to the cutting direction and do not reverse the process.
7. Do not operate the saw blade without a protective cover.
