The instructions for using a hand winch are as follows:

Install the winch on a suitable support or fixing point to ensure its stability and reliability.

A steel wire rope or chain that connects heavy objects or goods to a winch.

Grasp the handle with three hands and transfer force to the gear set on the winch by manually rotating the handle. By manually rotating, the gear set will rotate accordingly, causing the steel wire rope or chain to wrap around the drum of the winch to achieve the purpose of lifting or pulling heavy objects.
