Page 3: Safety Instructions
Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) , and other safety regulations. - Page 4 Safety Instructions Caution We develop, design, and manufacture our products to be used for automatic control equipment, and provide them for peaceful use in manufacturing industries. Use in non-manufacturing industries is not covered. Products we manufacture and sell cannot be used for the purpose of transactions or certification specified in the Measurement Act.
- Page 5 Design / Selection Warning 1. Confirm the specifications. Products represented in this catalog are designed only for use in compressed air systems. Do not operate at pressures or temperatures, etc., beyond the range of specifications, as this can cause damage or malfunction. (Refer to the specifications.) We do not guarantee against any damage if the product is used outside of the specification range.
- Page 6 12. Select a speed within the product’s allowable energy value. If the product’s kinetic energy of the load exceeds the allowable value, it could damage the product, and cause a hazard to humans and damage the machinery and equipment. 13. Provide a shock absorber if the kinetic energy that is applied to the product exceeds the allowable value.
- Page 7 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. 2. Ensure sufficient space for maintenance activities. When installing the products, allow access for maintenance.
- Page 8 12. Place an external stopper in a position that is away from the rotating shaft. If the stopper is placed near the rotating shaft, the torque that is generated by the product itself will cause the reaction force which is directed to the stopper to be redirected and applied to the rotating shaft.
- Page 9 Caution 1. Do not use organic solvent to wipe the area of the name plate that shows the model. It will erase what is indicated on the name plate. 2. Do not hit the rotating shaft by securing the body or hit the body by securing the rotating shaft.
- Page 10 Lubrication Warning 1. This product should be used without lubrication. Although it will operate even if it is lubricated, it could lead to sticking or slipping. Air Supply Warning 1. Type of fluids Use compressed air. 2. When there is a large amount of moisture Compressed air containing a large amount of moisture can cause malfunction of pneumatic equipment.
- Page 11 Operating Environment Warning 1. Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, steam, or where there is direct contact with any of these. Refer to the construction for information on the rotary actuator material. 2. Do not expose the product to direct sunlight for an extended period of time. 3.
- Page 12 Auto Switches Precautions Design / Selection Warning 1. Confirm the specifications. If the product is used with excess load applied or beyond the specification range, this may cause the product to break or malfunction. We do not guarantee against any damage if the product is used outside of the specification range.
- Page 13 8. Provide enough space for the lead wire. Applying stress to the lead wire and auto switch body connection part increases the risk of disconnection. Provide a space of at least the min. bending radius from the lead wire and auto switch body connection part.
- Page 14 2) If the internal resistance of a light emitting diode causes a problem, select an auto switch without an indicator light. <Solid state / 2-wire type> Generally, the internal voltage drop of the solid state auto switch is larger than that or the reed auto switch.
- Page 15 5. Mount an auto switch at the center of the operating range. In the case of 2-color display auto switch, mount it at the center of the green LED illuminating range. Adjust the mounting position of the auto switch so that the piston stops at the center of the operating range.
- Page 16 5. Avoid repeatedly bending or stretching lead wires. Broken lead wires will result from repeatedly applying bending stress or stretching force to the read wires. Stress and tensile force applied to the connection between the lead wire and auto switch increases the possibility of disconnection.
- Page 17 Operation Environment Warning 1. Never use in an atmosphere with explosive gases. The structure if auto switches is not intended to prevent explosion. This may lead to explosion hazard. Caution 1. Do not use in an area where a magnetic field is generated. Auto switches will malfunction or magnets inside rotary actuators will become demagnetized.
- Page 18 Maintenance Warning 1. Removal of equipment, and supply/exhaust of compressed air. Before any machinery or equipment is removed, first ensure that the appropriate measures are in place to prevent the fall or erratic movement of driven objects and equipment, then cut off the electric power and reduce the pressure in the system to zero.

Page 27: Setting Of Rotation Time
Setting of rotation time It is necessary to calculate the inertial load and kinetic energy in the application prior to setting the speed of the actuator. The inertial load generated in the application may be high even if the torque required in the application is low, this may lead to damage to the internal components of the actuator. -

Page 30: Auto Switch
Auto switch The rotary actuator has a magnet mounted on its piston and an auto switch on the outside of the body to detect the piston position (table position). Rotary actuators have a short piton stroke, so detection should be done at the stroke end. Refer to page 18 for mountable auto switches. -

Page 32: Maintenance And Inspection
Maintenance and Inspection Periodic inspection is necessary for optimum use. Generally, annual inspection is recommended for the rotary actuator. Even if no problem is found, seal parts replacement is recommended every three years. It is highly possible that the actuator is operated out of specification when the components like pinion, piston, bearing are broken. - Page 33 ■Disassembly procedure （1）Loosen cross recessed no.0 screw（size 10,15）or roundhead screw（size 20,30,40）. （2）Pull out the bearing retainer and the table from the body. Remove the bearing from the housing at this time. （3）Loosen hexagon socket head bolt to remove the cover assembly and the end cover assembly. （4）Push piston assembly from one side to pull out two piston assembly from the body.
- Page 34 ■Assemble procedure （1）Clean each component sufficiently before assembled to prevent a dust from attaching. Apply the grease which is enclosed to the seal set to each part shown in Table 11. The referential amount of applied grease is to the extent which can brighten the surface of components. After that, mount a piston seal to a piston with care not to damage the piston seal.
