Caution Design/Selection 1. Use the product within the limits of the maximum usable stroke. The piston rod will be damaged if operated beyond the maximum stroke. Refer to the Cylinder Model Selection Procedure for the maximum useable stroke. 2. Operate the cylinder component parts within a range such that collision damage will not occur at the stroke end. For applications where a piston with inertial force strikes a cover and stops at the stroke end, follow the cylinder model selection procedure (Best Pneumatics No. 2), or select while taking into account the allowable kinetic energy indicated in the each model specifications. 3. Use a speed controller to adjust the cylinder drive speed, gradually increasing from a low speed to the desired speed setting. 4. Provide intermediate supports for long stroke cylinders. Provide intermediate supports for cylinders with long strokes to prevent rod damage due to sagging of the rod, deflection of the tube, vibration and external loads, etc. In addition, thoroughly examine the possibility of buckling and establish safety measures, such as constructing a guide outside of the product, etc. 5. If pressure is applied to the external cylinder parts, there is a possibility that air will get inside the cylinder from the rod seal section. (Example: inside a chamber, etc.) Warning Mounting 1. Operation manual Install the product and operate it only after reading the operation manual carefully and understanding its contents. Also, keep the manual in a location where it can be referred to as necessary. 2. Ensure sufficient space for maintenance activities. When installing the products, allow access for maintenance. 3. Tighten threads with the proper tightening torque. When installing the products, follow the listed torque specifications. 4. Do not place a magnetic object near the product. The auto switch is a magnetic sensing type. If a magnetic object is placed close to it, the rotary actuator could operate suddenly, which could pose a hazard to humans and damage the machinery and equipment. 5. Do not perform additional machining to the product. Additional machining to the product can result in insufficient strength and cause damage to the product. This can lead to possible human injury and damage to the surrounding equipment. 6. Do not enlarge the fixed throttle by modifying the pipe connectors. If the hole diameter is enlarged, the product’s rotation speed will increase, causing the shock force to increase and damage to the product. As a result, it could pose a hazard to humans and damage the machinery and equipment. Mounting 1. Be certain to align the rod axis with the load and direction of movement when connecting. When not properly aligned, the rod and tube may be twisted, and damage may be caused due to wear on areas such as the inner tube surface, bushings, rod surface and seals. 2. When an external guide is used, connect the rod end and the load in such a way that there is no interference at any point within the stroke. 3. Do not scratch or gouge the sliding parts of the cylinder tube or piston rod, etc., by striking or grasping them with other objects. Cylinder bores are manufactured to precise tolerances, so that even a slight deformation may cause malfunction. Also, scratches or gouges, etc., in the piston rod may lead to damaged seals and cause air leakage. 4. Prevent the seizure of rotating parts. Prevent the seizure of rotating parts (pins, etc.) by applying grease. 5. Do not use until you can verify that equipment can operate properly. Verify correct mounting by function and leak tests properly after compressed air and power are connected following mounting or repair. 6. Cantilever fastening If a cylinder is actuated at high speed when mounted with one side fastened and one side free (basic type, flange type, direct mount type), the bending moment may act on the cylinder due to vibration at the stroke end, causing damage to the cylinder. In such cases, install a mounting bracket to suppress vibration of the cylinder body, or reduce piston speed until the cylinder body does not vibrate at the stroke end. Also, use a mounting bracket when moving the cylinder body, or mounting a long stroke cylinder horizontally with one-sided fastening. 7. Be very careful when handling the product. Depending on the handling method, there is a risk that the corners of the product will injure your hand or fingers, etc. Caution Actuators Precautions 2 Be sure to read this before handling. 9
