1. Listen to the sound inspection: When installing the blade, please use the right index finger to carefully lift the blade and make the blade hang in the air, then tap the blade body with a wooden hammer, and listen to the sound from the blade body, such as the blade that emits a dull sound. It proves that the cutter body is often damaged by external force, and there are cracks and damages. Use of such blades should be banned immediately. The use of a chipper blade that emits a dull sound is prohibited!
2. Blade installation: Before installing the blade, please carefully clean the dust, chips and other debris on the rotating bearing installation surface of the foot cutter, and keep the bearing installation surface and the foot cutter clean.
