Maintenance points: Regular cleaning: Use diesel or kerosene to soak and clean, remove the sealing cover to thoroughly remove impurities, and check the wear after air drying; Lubrication management: Use high-temperature grease (such as high-quality yellow dry oil) to melt over a slow fire and then immerse the bearing to ensure full penetration; Condition monitoring: Use a wooden stick to conduct the rotation noise to judge abnormalities. Loose or serious defects need to be replaced in time wi...
