Through these specifications, this specifi-cation aims to assist designers and manufacturers in reducing the possibility of injury when theseproducts are used in accordance with the operational instructions.The
4、 equipment user must recognize, however, that a standard alone will not necessarily preventinjuries. Like other physical activities, exercise involving this equipment involves the risk of injury,particularly if the equipment is used improperly or is not properly maintained. In addition, users withph
5、ysical limitations should seek medical advice and instruction from the fitness facility prior to usingthis equipment. Certain physical conditions or limitations may preclude some persons from using thisequipment as intended by the manufacturer, and using this equipment may increase the risk of injur
