3. knut on the connector fully anti clockwise RELEASE VALVE 3 This can be used to reduce or release the pressure in the system The rate of pressure reduction is dependent upon the degree of rotation when opening the valve Minimal force is required to seal the system VOLUME CONTROL 2 2 The pressure generated can be finely adjusted by turning the fine adjustment valve 2 either clockwise or anticlockwise to increase or decrease pressure accordingly 3 OVER PRESSURE PROTECTION 5 To adjust the maximum output pressure of the system turn the nuts 5 to increase or decrease the stroke length IMPORTANT Under no circumstances should the fine adjustment valve 2 be wound back beyond the red line indicator on the body Should this occur then the pressure must be released from the system before attempting to re engage the fine adjustment valve PRESSURE VACUUM SELECTION 4 Press the selector 4 as indicated on the label to engage the desired mode Ensure that the release valve 3 is open before changing mode Red Line NOTE Indicator The system should only be used for pressurising small volumes due to its small displacement lf the system has not been used for a period of time it could be difficult to operate on the first stroke The cylinder has been lightly greased on assembly but if additional lubrication should ever be required then apply a minimal amount to the inside of the cylinder Access is via the three retaining screw
