What should be done if a strange noise occurs when using a hand-operated pulley? Stop the machine and check whether there are foreign objects inside the pulley. Or, perhaps the gears have worn or loosened. If necessary, replace the damaged parts and ensure that all components are securely connected. Regular maintenance of the hand-operated pulley can reduce the occurrence of such situations. Periodic inspection of the chain is also important to observe for cracks on the surface and deformation of the links. If the chain is deformed, it may cause the sprocket to jam the chain, resulting in noise. When using a hand-operated pulley, it is important to avoid overloading.
