Design/Selection Caution Mounting 1. Do not use below the speed adjustment range specified for the product. If the product is used below the specified speed adjustment range, it could cause the product to stick, slip, or the movement to stop. 2. Do not apply an external torque to the product that exceeds the rated output. If an external force that exceeds the product’s rated output is applied to the product, it could damage the product. 3. The holding torque of the rotating end of the double piston type. If the internal piston of a double piston product comes in contact with the angle adjustment screen or the cover and stops, the holding torque at the rotating end is one half of the actual output. 4. If it is necessary to provide repeatability of the rotation angle, directly stop the load externally. Even with a product that is equipped with an angle adjuster, there are times in which the initial rotation angle could change. 5. Do not use under hydraulic pressure. The product will be damaged if it is used by applying hydraulic pressure. 6. There is a possibility of backlash being generated when stopping the double piston style in the middle with a valve of the closed center type. 7. For the vane type product, if it is necessary to ensure a rotation angle, make sure to use a minimum pressure of 0.3 MPa. 8. Do not use the Made-to-Order -XC30 at low speeds. Although fluorine grease is used, it is not designed for low-speed applications. For information on fluorine grease, refer to the Material Safety Data Sheet (MSDS). 9. Do not use in places where there are many temperature fluctuations. When using in lower temperature applications, use caution so that frost does not occur inside the cylinder or the piston rod. Operation may be unstable. 10. Adjust the speed control in the environment in which it will be used in. Speed adjustment may be changed if the environment is different. 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. Before adjusting the angle by supplying air pressure, take appropriate measures to prevent the equipment from rotating unnecessarily. When an adjustment is performed under air pressure, the equipment could rotate and fall during the adjustment, depending on the mounted placement of the equipment. As a result, it could pose a hazard to humans and damage the machinery and equipment. 5. Do not loosen the angle adjustment screw beyond the allowable adjustment range. The angle adjustment screw could fall out if it is loosened beyond its allowable adjustment range and cause a hazard to humans and damage to machinery and equipment. 6. 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. 7. 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. 8. 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. 9. If shaft couplings are used, use those with angular freedom. If shaft couplings that lack angular freedom are used, they could scrape due to eccentricity, leading to equipment malfunction and product damage. As a result, it could pose a hazard to humans and damage the machinery and equipment. 10. Do not apply to the shaft a load that exceeds the values given in a catalog. If a load that exceeds the allowable value is applied to the product, it could lead to equipment malfunction, a hazard to humans, and damage to the machinery and equipment. Provided that a dynamic load is not generated, a load that is within the allowable radial/thrust load can be applied. However, applications in which the load is applied directly to the shaft should be avoided wherever possible. The methods such as those described below are recommended to prevent the load from being applied directly to the shaft in order to ensure a proper operating condition. Mounting Warning 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. Warning Rotary Actuators Precautions 2 Be sure to read this before handling.
