CONTROLS AND INDICATORS 2 3 1 CONTROLS No controls are used on any components of any RSS However the optional accessories required for use in conjunction with the RSS do contain the operational controls indicated below a Manual Air Compressor The only controls on the Manual Air Compressor are the foot lever used to deliver pressure and a sliding valve ring that permits isolating one of the two cylinders thereby increasing the delivered pressure and decreasing the delivered volume by a factor of 2 Air Cylinder 3000 psi The only control on the Air Cylinder 3000 psi is the shut off valve that prevents the flow of compressed air Regulator 300 psi CGA The only controls on the Regulator 300 psi CGA are the shut off valve assembly and the pressure adjusting knob assembly The shut off is either open to permit regulated delivery air to pressurize the system or closed to prevent seal off regulated delivery air from pressurizing the system The pressure adjustment knob is turned to control the delivery pressure up to 250 psi 17 2 bar maximum Single Strut Controller G2 Single Strut Controller The controls on the Single Strut Controller G2 Single Strut Controller are rocking levers or pushbuttons with UP and DOWN markings that can pressurize the strut to extend or release the pressure to collapse A gauge is provide to monitor the air pressure provided to the strut A 250psi 17 2 bar relief valve is intergraded i
