Handling Caution With rod boot (M12 x 1.75 x 25, Hexagon thin socket head bolt) CE00008 (M12 x 1.75 x 28, Hexagon thin socket head bolt) CE00032 Series MB Specific Product Precautions 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. Handling Caution Mounting and Piping Caution Non-rotating rod (Double acting, Single rod) 1. Do not open the cushion valve beyond the stopper. Crimping (o32) or a snap ring (o40 to o100) is provided to prevent the accidental removal of the cushion valve. Do not open the valve beyond the mechanism. If air is supplied, the cushion valve may shoot out from the cover. 1. Avoid using the air cylinder in such a way that more than allowable rotational torque would be applied to the piston rod. If rotational torque is applied, the non-rotating guide will deform, thus affecting the non-rotating accuracy. valve may shoot out from the cover. 1. Mounting a workpiece on the rod end 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. To tighten, take precautions to prevent the tightening torque from being applied to the non-rotating guide. 1. Do not turn the piston rod with the rod boot kept locked. When turning the piston rod, loosen the band once and do not twist the rod boot. 2. Set the breathing hole in the rod boot downward or in the direction that prevents entry of dust or water content.

Use the air cushion at the end of cylinder stroke. Select the cylinder with bumper “N” if cushion valve is to be fully opened. Tie rods or piston assembly may be damaged if neither air cushion nor bumper is utilized. 3. When replacing mounting bracket, use a socket wrench.

When replacing a bracket, tie-rod nuts on the cylinder body become loosened. After retightening the tie-rod nuts with the proper tightening torque (Refer to Adjustment 3.), mount a mounting bracket. 5. Mounting precision is required for the trunnion type cylinder. It is difficult to align the axial center of the trunnion with the axial center of the cylinder. Thus, if this type of cylinder is disassembled and reassembled, the required dimensional accuracy cannot be attained, which may lead to malfunctions.
