Assembly Tighten screw (7). Ø Tightening torque: ✓ SRH-plus 20-30: 1.2 Nm / SRH-plus 35-50: 2.1 Nm Swivel repeatedly to test the setting, adjust if necessary. Ø Version with limiting sleeves Loosen screw of the limiting sleeve (6) approx. one revolution. Ø Actuate air connection B (4).
Assembly 5.3.2 Adjust swiveling speed CAUTION Material damage due to too high swiveling speed! If the swiveling speed is too high, the assembly will be decelerated abruptly by the shock absorber and will continue to oscillate until reaching the end position. This will overload the shock absorber and may cause damage to it.
Assembly For the variants with pneumatic and locked center position, air supply throttle valves must be mounted to various air connections, Pneumatic connection 20]. The sequence for setting the swivel speed with the air supply throttle valve is identical to the sequence with mounted exhaust throttle valve.
