11.4 Change of the pressure limiting valve

In order to protect the lubricant circuit, a pressure limiting valve is integrated in the device (fig. 14, pos. 2). It opens from a lubricant
pressure of 280 bar. Proceed as follows to change the pressure limiting valve:

Loosen the screw plug with Allen key AF 8 (see fig. 14, pos. 1) and remove it including the Cu sealing ring.

Unscrew the pressure limiting valve with a hexagon wrench AF 9.

At the assembly of the pressure limiting valve, make sure that the ball, valve piston and spring are in the correct order in the
housing of the pressure limiting valve.

Screw the pressure limiting valve in again. Make sure that the pressure limiting valve is firmly seated in the pump housing because
it seals with a cutting edge.

Screw the screw plug incl. Cu sealing ring in again.
