Pneumatic Clean Series

209Rotary Actuator/Common Precautions 3Be sure to read before handling. Refer to pages 7 to 16 of Front matter for safety instructions andcommon precautions with clean series. Refer to the main text for precautions for each series.WarningAir SupplyqUse clean air.Do not use compressed air that contains synthetic oil, salt, andcorrosive gases in which chemicals and organic solvents arepresent, because it could cause equipment damage ormalfunction.CautionqInstall an air filter.Install an air filter close to and upstream of the valve. Select afiltering degree of 5µm or smallerwTake measures such as installation of after cooler,air dryer or drain catch.Compressed air containing a large amount of drainage could causethe rotary actuator or other types of pneumatic equipment tomalfunction. Therefore, take appropriate measures to ensure airquality, for example, by installing an after cooler, air dryer or draincatch.eUse the product within the specified range of fluidand ambient temperature.Take freeze proof measures when the temperature is 5°C orbelow. Otherwise the moisture in the circuit may freeze tocause damage to the packing or malfunction.For detailed information regarding the quality of the compressedair descried above, refer to pages 8 to 9 of Front matter.WarningEnvironmentqDo not use in environments where there is danger ofcorrosion.Refer to the respective construction diagram for details on thematerials used in the rotary actuator.Speed and Cushion AdjustmentWarningqIn speed adjustment, start from the low speed endand gradually move to higher values.If the speed adjustment is performed from the high speed end,it could damage the product. As a result, it could cause humaninjury or damage to machinery and equipment.wThe cushion needle is not factory adjusted. Pleaseadjust it acording to the operation speed and themoment of inertia of the load.The absorption of kinetic energy by the cusion is determinedby the needle adjustment. If the adjustment is incorrect, it candamage products and equipment or even cause injury topersonnel.eDo not operate the product with its cushion needlefully closed.If could tear up the seal, causing human injury or damage tomachinery and equipment.rDo not apply exessive force to loosen the cusiohneedle.The needle itself is provided with a pull stop, which could bedamaged by application of excessive force to loosen theneedle. As a result, it could pose a hazard to humans ordamage the machinery and equipment.WarningMaintenanceqFollow the procedures given in the operation manual toperform maintenance and inspection. Improper handlingcould lead to malfunction or damage the machinery andequipment.wIn the course of maintenance, do not disassemble theproduct with its power on or with air pressure applied.eWhen the product is overhauled, be sure to performan appropriate functionality inspection.Failure to perform functionality inspection will lead to theproduct's inability to meet the specifications.CautionqFor lubrication, use the type of grease that is usedfor the respective product.Use of a lubricant out of the specifications could damage theseals.CautionRefer to pages 5 to 7 for common precautions onauto switches.190
