1. Do not use this winch to pull or move a person. Don't overload. 3, if the wire rope has been damaged, broken, peaceful rust or knot, do not use. 4. When working, do not fasten the hook at the end of the wire rope on the wire rope, so as not to wear the wire rope. 5, when pulling the goods, the wire rope and the reel should be kept vertical, otherwise easy to make the wire rope wear. 6. Use pulleys to reduce the load on the winch and wire rope when the winch is used to pull heavy loads. 7. Do not use the winch to pull the goods when the wire rope is wound less than 5 times on the reel. Otherwise, the plate will not bear the heavy load and accident. 8.
