Note!
Spring ratio p/f depends upon the dimensions of the spring. It is recommended to check the
dimensions prior to adjusting the pressure.
When the safety relief valve is not functioning properly, the pump must immediately be taken
out of service. The safety relief valve must be checked by your local supplier.
