"Attention: Dry air must be used for application below 0°C" General The piston rod lock devices are clamping units mounted on the microcylinders front head. They allow the piston rod to lock in any position. Piston rod clamping is mechanically obtained by springs actuated purpose-made jaws. This method allows to lock the cylinder in the desired position, should the air pressure drop. The piston rod lock device is not a safety device . Use and maintenance Operate within the specified technical characteristics. The piston rod lock does not requiremaintenance if properly utilised. The working inlet port has to be pressurised for assembling the piston rod lock device on cylinder. Alternatively adjust the jaws with screw located on connection. Spare parts are not available.
