The safety valve’s factory setting for opening pressure = working pr 25 to +30 bars.
Upon each service inspection the setting must be tested and, if necessary, adjusted.
When mounting, affix ball and pressure plate to the spring with lubrication.
The seat is screwed on using a 10mm socket wrench (no gasket required).
Before testing with a pressure gauge, make sure that two threads are visible behind the locknut.
