Precautions Caution on Handling/Disassembly Warning Caution o20 0.2 o25 0.25 o32 0.25 o40 0.44 Be sure to read before handling. Refer to front matter 57 for Safety Instructions and pages 3 to 12 for Actuator and Auto Switch Precautions. 1. Do not rotate the cover. If a cover is rotated when installing a cylinder or screwing a fitting into the port, it is likely to damage the junction part with cover. 2. In the case of exceeding the standard stroke length, implement an intermediate support. When using cylinder with longer stroke, implement an intermediate support for preventing the joint of rod cover and cylinder tube from being broken by vibration or external load. 1. Avoid using the air cylinder in such a way that rotational torque would be applied to the piston rod. If rotational torque is applied, the non-rotating guide will become deformed, thus affecting the non-rotating accuracy. Refer to the table below for the approximate values of the allowable range of rotational torque. To screw a bracket or a nut onto the threaded portion at the tip of the piston rod, make sure to retract the piston rod entirely, and place a wrench over the flat portion of the rod that protrudes. Tighten it by giving consideration to prevent the tightening torque from being applied to the non-rotating guide. Allowable rotational torque (N・m or less) 2. When replacing rod seals, please contact SMC. Air leakage may be happened, depending on the position in which a rod seal is fitted. Thus, please contact SMC when replacing them. 3. Not able to disassemble. Cover and cylinder tube are connected to each other by caulking method, thus making it impossible to disassemble. Therefore, internal parts of a cylinder other than rod seal are not replaceable. 4. Do not touch the cylinder during operation. Use caution when handling a cylinder, which is running at a high speed and a high frequency, because the surface of a cylinder tube could get so hot enough as to cause you get burned. 240 Series CM2RK
