Installation and Operating Manual Series RA 4.5.1 Removal of the shaft 4.5.3 Removal of the piston Remove the circlip and the sliding ring from the shaft. Remove the end cap on the actuator. Remove the return springs (singleacting actuators). The actuator has fastened springs. The removal of the springs is safer compared to actuators with nonfastened springs. Clip must not be over-stretched ! Press the shaft downwards out of the casing.
Installation and Operating Manual Series RA Table 1 4.6 Mounting the return springs Warning - Danger of injury ! Loosen the end caps only when the actuator is isolated from the compressed air supply. In order to achieve a symmetrical pressure distribution, it is necessary to insert the springs as shown in the diagrams below. Remove the end cap on the actuator. Set the desired number of return springs in the round insets in the piston.
