Series CU Safety Instructions These safety instructions are intended to prevent a hazardous situation and/or equipment damage. These instructions indicate the level of potential hazard by a label of "Caution", "Warning", or "Danger". To ensure safety, be sure to observe ISO 4414 Note 1), JIS B 8370 Note 2) and other safety practices. Caution : Operator error could result in injury or equipment damage. Warning : Operator error could result in serious injury or loss of life.
Series CU Actuator Precautions 1 Be sure to read before handling. Design Warning Design Warning 1. There is a danger of sudden or erratic action by cylinders if sliding parts of machinery are twisted and changes in forces occur. 9. Consider the action when operation is restarted after an emergency stop or an abnormal stop. In such cases, bodily injury may occur, e.g., by catching hands or feet in the machinery, or damage to the machinery itself may occur.
Series CU Actuator Precautions 2 Be sure to read before handling. Mounting Cushion Caution Caution 1. Be certain to align the rod center of the piston axis with the load and direction of movement when connecting. When a cylinder is not properly aligned, the rod and tube may be twisted. This can cause wear on areas such as the inner tube surface, bushings, rod surface, seals, and cause damage to these areas. 2.
Series CU Actuator Precautions 3 Be sure to read before handling. Operating Environment Warning 1. Do not use in environments where there is a danger of corrosion. 2. In dusty conditions or where water or oil splashing is a regular occurrence, protect the rod by installing a rod cover. 3. When using auto switches, do not operate in an environment where there are strong magnetic fields. Maintenance Warning 1.
Series CU Auto Switch Precautions 1 Be sure to read before handling. Design and Selection Warning 1. Confirm the specifications. Read the specifications carefully and use the product appropriately. The product may be damaged or malfunction if it is used outside the range of specifications for load current, voltage, temperature or impact. 2. Take precautions when multiple cylinders are used close together.
Series CU Auto Switch Precautions 2 Be sure to read before handling. Mounting and Adjustment Warning Warning 1. Do not drop or bump. Do not drop, bump, or apply excessive impacts (300m/s² or more for reed switches and 1000m/s² or more for solid state switches) while handling. Although the body of the switch may not be damaged, the inside of the switch could be damaged and cause a malfunction. 2. Do not carry a cylinder by the auto switch lead wires. Never carry a cylinder by its lead wires.
Series CU Auto Switch Precautions 3 Be sure to read before handling. Operating Environment Warning 1. Never use in the presence of explosive gases. The construction of our auto switches does not make them explosionproof. Never use them in the presence of an explosive gas, as this may cause a serious explosion 2. Do not use in an area where a magnetic field is generated. Auto switches will malfunction or magnets inside cylinders will become demagnetized if used in such an environment.
Series CU Specific Product Precautions Be sure to read before handling. Refer to pages 12 through 18 for Safety Instructions, Actuator Precautions, and Auto Switch Precautions. Installation and Removal of Snap Rings Selection Caution Caution 1. Use appropriate pliers (C-type snap ring installing tool) for installation and removal of snap rings. 2.
