Since Series C M does not have an air release valve, release air from components other than the cylinder (e.g. from piping, etc.). 2. When operating a cylinder for the first time, be sure to release the air at low pressure. When the air release is complete, operate the cylinder at reduced pressure, then gradually increase it to the normal operating pressure. owever, the piston speed at this time should be adjusted to the minimum speed. Caution 1. When mounting with bracket mounting nuts, tighten them using the tightening torques in the table below as a guide. ore size Mounting Mounting nut thread M x 1. M x 1. M x 1. M33 x 1.

When mounted with one side attached and one side free (basic type, flange type) and operating at high speed, the bending moment acts on the cylinder due to oscillation at the stroke end, which may cause cylinder damage. In this type of situation, install brackets to suppress the oscillation of the cylinder body, or reduce the piston speed enough so that the cylinder body does not oscillate at the stroke end. 23
