Manual winch is a commonly used lifting tool for handling heavy objects and lifting equipment. Here are some precautions for using manual winches:

　　1.Before using the manual winch, please carefully read and understand the user manual, and strictly follow the instructions.

　　2.Before using a manual winch, it is necessary to check whether the winch is intact and ensure that there are no debris in the winch and its surrounding area.

　　3.When using a manual winch, attention should be paid to the center of gravity of the heavy object and overload should be avoided. If it is necessary to lift heavy objects beyond the rated load of the winch, a larger model of winch should be selected.

　　4.When using a manual winch, the rotation direction of the winch handle should be kept consistent and the weight should be gradually raised or lowered. Do not use excessive force or suddenly change direction to avoid damaging the winch or causing accidents.

　　5.When using a manual winch, the handle should be kept dry and clean, and attention should be paid not to get stuck or twist the handle.

　　6.When using a manual winch, the steel wire rope should be kept smooth and tidy to avoid friction or twisting with other objects. The steel wire rope needs to be regularly inspected and replaced to ensure its integrity.

　　7.When using a manual winch, attention should be paid to the environment and safety conditions around the winch. Do not use the winch in unstable or unsafe areas to avoid accidents.

　　8.After using a manual winch, it should be stored in a dry, ventilated, non corrosive, and safe place. Avoid exposing the winch to damp, high temperature, corrosive or easily colliding environments 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.
