21 Series MXH 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 1 Note 1), JIS B 37 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. Danger : In extreme conditions, there is a possible result of serious injury or loss of life. Note 1) ISO 1 : Pneumatic fluid power -- Recommendations for the application of equipment to transmission and control systems. Note 2) JIS B 37 : Pneumatic system axiom. Warning 1. The compatibility of pneumatic equipment is the responsibility of the person who designs the pneumatic system or decides its specifications. Since the products specified here are used in various operating conditions, their compatibility for the specific pneumatic system must be based on specifications or after analysis and/or tests to meet your specific requirements. 2. Only trained personnel should operate pneumatically operated machinery and equipment. Compressed air can be dangerous if an operator is unfamiliar with it. Assembly, handling or repair of pneumatic systems should be performed by trained and experienced operators. 3. Do not service machinery/equipment or attempt to remove components until safety is confirmed. 1. Inspection and maintenance of machinery/equipment should only be performed after confirmation of safe locked-out control positions. 2. When equipment is to be removed, confirm the safety process as mentioned above. Cut the supply pressure for this equipment and exhaust all residual compressed air in the system. 3. Before machinery/equipment is restarted, take measures to prevent shooting-out of cylinder piston rod, etc. (Bleed air into the system gradually to create back-pressure.). Contact SMC if the product is to be used in any of the following conditions: 1. Conditions and environments beyond the given specifications, or if product is used outdoors. 2. Installation on equipment in conjunction with atomic energy, railway, air navigation, vehicles, medical equipment, food and beverages, recreation equipment, emergency stop circuits, press applications, or safety equipment. 3. An application which has the possibility of having negative effects on people, property, or animals, requiring special safety analysis. 1

22 Series MXH Actuator Precautions 1 Be sure to read before handling. Warning Precautions on design 1. There is a possibility of dangerous sudden action by air cylinders if sliding parts of machinery are twisted due to external forces, etc. In such cases, human injury may occur; e.g., by catching hands or feet in the machinery, or damage to the machinery itself may occur. Therefore, the machine should be designed to avoid such dangers. 2. A protective cover is recommended to minimize the risk of personal injury. If a stationary object and moving parts of a cylinder are in close proximity, personal injury may occur. Design the structure to avoid contact with the human body. 3. Securely tighten all stationary parts and connected parts so that they will not become loose. When a cylinder operates with high frequency or a cylinder is installed where there is a lot of vibration, ensure that all parts remain secure.. A deceleration circuit or shock absorber, etc., may be required. When a driven object is operated at high speed or the load is heavy, a cylinder s cushion will not be sufficient to absorb the shock. Install a deceleration circuit to reduce the speed before cushioning, or install an external shock absorber to relieve the shock. In this case, the rigidity of the machinery should also be examined.. Consider a possible drop in operating pressure due to a power outage, etc. When a cylinder is used in a clamping mechanism, there is a danger of work dropping if there is a decrease in clamping force due to a drop in circuit pressure caused by a power outage, etc. Therefore, safety equipment should be installed to prevent damage to machinery and human injury. Suspension mechanisms and lifting devices also require consideration for drop prevention.. Consider a possible loss of power source. Measures should be taken to protect against human injury and equipment damage in the event that there is a loss of power to equipment controlled by air pressure, electricity or hydraulics, etc. 7. Design circuitry to prevent sudden lurching of driven objects. When a cylinder is driven by an exhaust center type directional control valve or when starting up after residual pressure is exhausted from the circuit, etc., the piston and its driven object will lurch at high speed if pressure is applied to one side of the cylinder because of the absence of air pressure inside the cylinder. Therefore, equipment should be selected and circuits designed to prevent sudden lurching, because there is a danger of human injury and/or damage to equipment when this occurs.. Consider emergency stops. Design so that human injury and/or damage to machinery and equipment will not be caused when machinery is stopped by a safety device under abnormal conditions, a power outage or a manual emergency stop. 9. Consider the action when operation is restarted after an emergency stop or abnormal stop. Design the machinery so that human injury or equipment damage will not occur upon restart of operation. When the cylinder has to be reset at the starting position, install manual safety equipment. Warning Selection 1. Check the specifications. The products advertised in this catalog are designed according to use in industrial compressed air systems. If the products are used in conditions where pressure, temperature, etc., are out of specification, damage and/or malfunction may be caused. Do not use in these conditions. Consult SMC if you use a fluid other than compressed air. 2. Intermediate stops. When intermediate stopping of a cylinder piston is performed with a 3 position closed center type directional control valve, it is difficult to achieve stopping positions as accurate and minute as with hydraulic pressure, due to the compressibility of air. Furthermore, since valves and cylinders, etc. are not guaranteed for zero air leakage, it may not be possible to hold a stopped position for an extended period of time. Contact SMC in case it is necessary to hold a stopped position for an extended period. Caution 1. Operate the piston within a range such that collision damage will not occur at the end of the stroke. Operate within a range such that damage will not occur when the piston having inertial force stops by striking the cover at the stroke end. Refer to the cylinder type selection procedure for the range within which damage will not occur. 2. Use a speed controller to adjust the cylinder drive speed, gradually increasing from a low speed to the desired speed setting. 19

23 Series MXH Actuator Precautions 2 Be sure to read before handling. Caution Mounting 1. Be certain to match the rod shaft center with the load and direction of movement when connecting. When not properly matched, problems may arise with the rod and tubing, and damage may be caused due to friction on areas such as the inner surface of the tubing, bushings, rod surface and seals. 2. Do not scratch or dent 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 faulty operation. Moreover, scratches or dents, etc. in the piston rod may lead to damaged seals and cause air leakage. 3. Do not use until you verify that the equipment can operate properly. After mounting, repair or modification, etc., connect the air supply and electric power, and then confirm proper mounting by means of appropriate function and leak inspections.. Instruction manual. The product should be mounted and operated after thoroughly reading the manual and understanding its contents. Keep the instruction manual where it can be referred to as needed. Caution Piping 1. Preparation before piping. Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove cutting chips, cutting oil and other debris from inside the pipe. 2. Wrapping of pipe tape. When screwing together pipes and fittings, etc., be certain that cutting chips from the pipe threads and sealing material do not get inside the piping. Also, when pipe tape is used, leave 1. to 2 thread ridges exposed at the end. Wrapping direction Expose approx. 2 threads Caution Pipe tape Lubrication 1. Lubrication of non-lube type cylinder. The cylinder is lubricated at the factory and can be used without any further lubrication. However, in the event that it will be lubricated, use class 1 turbine oil (with no additives) ISO VG32. Stopping lubrication later may lead to malfunction due to the loss of the original lubricant. Therefore, lubrication must be continued once it has been started. Warning Air Supply 1. Use clean air. If compressed air includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases, etc., it can cause damage or malfunction. Caution 1. Install air filters. Install air filters at the upstream side of valves. The filtration degree should be µm or finer. 2. Install an air dryer, after cooler, etc. Air that includes much condensate causes malfunction of valves and other pneumatic equipment. To prevent this, install an air dryer or after cooler, etc. 3. Use the product within the specified range of fluid and ambient temperature. Take measures to prevent freezing, since moisture in circuits will be frozen under - C, and this may cause damage to seals and lead to malfunction. Refer to the Air Cleaning Equipment catalog for details on compressed air quality. Warning Operating Environment 1. Do not use in environments where there is a danger of corrosion. Refer to the construction drawings regarding cylinder materials. 2. In dirty areas, such as dusty locations or where water, oil, etc. splash on the equipment, take suitable measures to protect the rod. Warning Maintenance 1. Maintenance should be done according to the procedure indicated in the instruction manual. If handled improperly, malfunction and damage of machinery or equipment may occur. 2. Machine maintenance, and supply and exhaust of compressed air. When machinery is serviced, first confirm measures to prevent dropping of driven objects and run-away of equipment, etc. Then cut off the supply pressure and electric power, and exhaust all compressed air from the system. When machinery is restarted, confirm that operation is normal with actuators in the proper positions. Caution 1. Drain flushing. Remove condensate from air filters regularly. (Refer to specifications.)

24 Series MXH Specific Product Precautions 1 Be sure to read before handling. Refer to pages 1 through for safety instructions and precautions. Auto Switch Mounting Precautions When installing in close proximity Caution q In compact slides with D-A9 or D-F9 type auto switches, there is a danger of auto switch malfunction if the mounting pitch is less than the dimensions shown in Table 1. Be sure to allow at least the indicated interval. If it is not possible to maintain the intervals shown below, shielding will be necessary. Attach a steel plate or magnetic shielding plate (MU-S2), etc. to the relative position on a cylinder which will be close to an auto switch. (Inquire regarding details.) Auto switch malfunction will result if shielding plates are not used. Operating Direction with Different Pressure Ports q The compact slide can be piped from 3 directions. Confirm the pressure ports and operating direction. (See drawing below.) OUT Caution OUT port (on both sides) IN OUT port Table 1 Bore size (mm) MXH MXH MXH1 MXH d 1 (mm) L IN port (on both sides) IN port Caution Operating Precautions q Positively do not put fingers between the table and cylinder tube, as they can be caught when the piston rod retracts, If fingers are caught in a cylinder, there is a danger of injury due to the strong cylinder output, and therefore caution must be exercised. w Operate within the limits of the maximum movable weight and allowable moment. e When the output of the compact slide will be directly applied to the table, it should be applied along the rod axis. (See drawing below.) Stroke Direction Backlash Caution Since the connection between the piston rod and table is a floating structure, there is a maximum table backlash of.1mm in the stroke direction. (See drawing below.) Piston rod and table connection r Be sure to attach a speed controller, and adjust the speed to mm/s or less. 21

Since the table is supported by the linear guide, take care not to apply strong impact or large moment, etc. when mounting work pieces. Hold the table when fastening work pieces to it with bolts, etc. If the body is held while tightening bolts, etc., the guide section will be subjected to large moment, and there may be a loss of precision. For connection with a load having an external support/guide mechanism, select an appropriate connection method and perform careful alignment. Use caution, as scratches or nicks, etc. on the sliding parts of the piston rod can cause malfunction and air leakage. 23
