Instructions:

　　For marine lifting motors that are newly installed or installed after dismantling, the first empty test run should be carried out several times. However, before the installation is completed, it is forbidden to turn on the power. In use, it is absolutely forbidden to use in an unacceptable environment and in excess of the rated load and the number of rated closings per hour (120 times). During installation, commissioning and maintenance, the positioner must be strictly checked for flexibility and reliability. When the hook is raised to the upper limit position, the distance from the hook casing to the drum casing must be greater than 50 mm (10t, 16t, 20t must be greater than 120mm). When the hook is lowered to the lower limit position, the wire rope safety ring on the reel should be ensured, and the effective safety ring must be more than 2 turns. It is not allowed to simultaneously press two flashlight button buttons that move the marine hoist motor in the opposite direction.
