Maintenance Warning 1. Perform maintenance inspection according to the procedures indicated in the operation manual. If handled improperly, malfunction and damage of machinery or equipment may occur. 2. Maintenance work If handled improperly, compressed air can be dangerous. Assembly, handling, repair and element replacement of pneumatic systems should be performed by a knowledgeable and experienced person. 3. Drain flushing Remove drainage from air filters regularly. 4. Removal of equipment, and supply/exhaust of compressed air When components are removed, first confirm that measures are in place to prevent workpieces from dropping, run-away equipment, etc. Then, cut off the supply pressure and electric power, and exhaust all compressed air from the system using the residual pressure release function. When machinery is restarted, proceed with caution after confirming that appropriate measures are in place to prevent cylinders from sudden movement. Operating Environment Warning 1. Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these. Long machined parts made by machining plated carbon steel (end threads of piston rods, double-sided chamfer portion, tie rod threads etc.) are not plated. Consider a made-to-order product (-XC6/-XC7) when using in an environment where rusting or corrosion will be a problem. Refer to each construction on drawing on the rotary actuators material. 2. Do not expose the product to direct sunlight for an extended period of time. 3. Do not use in a place subject to heavy vibration and/or shock. 4. Do not mount the product in locations where it is exposed to radiant heat. 5. Do not use in dusty locations or where water or oil, etc., splash on the equipment. Use the heavy duty scraper type (-XC4) in situations where there is a lot of dust. Use a water resistant cylinder when there is splashing or spraying of a liquid. 6. When using auto switches, do not operate in an environment with strong magnetic fields. 7. If a shock absorber is attached to an actuator, read the Specific Product Precautions for the shock absorber. 8. A decrease in grease base oil may be accelerated by the properties of compressed air used in pneumatic equipment, the external environment, or operating conditions, etc., and the resulting drop in lubricating performance may have an effect on equipment service life. Caution 1. Internal lubricant or grease base oil may seep out of the cylinder depending on the operating conditions (an ambient temperature of 40°C or more, pressure retention, and low frequency actuation, etc.). Take great care when the clean environment is required. Actuators Precautions 4 Be sure to read this before handling. 11
