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. Do not operate with the cushion needle in a fully closed condition. Using it in the fully closed state will cause the cushion seal to be damaged. When adjusting the cushion needle, use the “Hexagon wrench key: nominal size 1.5”. 3. Do not open the cushion needle wide excessively. If the cushion needle were set to be completely wide (more than 3 turns from fully closed), it would be equivalent to the cylinder with no cushion, thus making the impacts extremely high. Do not use it in such a way. Besides, using with fully open could give damage to the piston or cover. Warning 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 nonrotating 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 nonrotating guide. 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. 5. The oil stuck to the cylinder is grease. 6. The base oil of grease may seep out. 7. When using a rod end bracket and/or pivot bracket, make sure they do not interfere with other brackets, workpieces and rod section, etc. 8. Combine the rod end section, so that a rod boot might not be twisted. If a rod boot is installed with being twisted when installing a cylinder, it will cause a rod boot to fail during operation. Caution Be sure to read this before handling. Refer to the back cover for Safety Instructions.
