- Clean Blade Area: Clean any debris or material residue from the blade mounting area on the cutter.
- Position New Blade: Align the new Hanchen YJ-50 Φ50mm replacement blade with the mounting points on the electric cutter. Ensure the blade is seated correctly and flush against the mounting surface.

4. Operating Guidelines
While this manual focuses on the blade, proper operation of the electric cutter with the new blade is essential for effective and safe cutting.
- Material Preparation: Ensure the material to be cut is laid flat and free of obstructions.
- Cutting Technique: Guide the electric cutter smoothly and steadily through the material. Avoid forcing the blade, as this can lead to uneven cuts or blade damage.
- Cutting Thickness: The Hanchen YJ-50 blade is designed for materials up to 10mm thick. Do not attempt to cut materials exceeding this thickness, as it can strain the motor and damage the blade.
- Overheating: If the cutter or blade becomes excessively hot, discontinue use and allow it to cool down before resuming operation.
