Manual winch is a common lifting tool with a long service life, but it requires daily maintenance to ensure its normal operation and extend its service life. The following are daily maintenance precautions for manual winches:

　　1. Cleaning: After use, clean the surface of the winch with clean water to remove dust and oil stains on the surface. When cleaning the winch, it is important to avoid splashing water inside the winch and onto the brakes.

　　2. Lubrication: Regularly lubricate the moving parts on the winch. Use appropriate lubricants, such as lubricating oil or grease, and apply them to the moving parts before use.

　　3. Steel wire rope: Regularly check the condition of the steel wire rope. If there is any twisting or breakage, it should be replaced immediately. When using, attention should be paid to the bending radius of the steel wire rope to avoid damage caused by too small bending radius. At the same time, the wire rope should be kept dry, clean, and smooth to avoid friction or twisting with other objects.

　　4. Brake: Regularly check the brake of the winch to ensure its normal operation. If the brake fails or malfunctions, the winch should be immediately stopped and the cause should be identified and repaired.

　　5. Storage: When maintaining the winch, it should be stored in a dry, ventilated, non corrosive, and safe place to avoid exposure to damp, high temperature, corrosive, or collision prone environments, in order to extend its service life.

　　Please note that these are just some general precautions, and specific usage and maintenance requirements may vary depending on the model and usage of the manual winch. To ensure the safety and reliability of manual winches, it is recommended to carefully read the user manual before use and follow the recommendations and requirements for use and maintenance.
