Valves

Remove valve cover 

1

. Before changing the valves 

2

note their orientation so they are replaced correctly.

NOTE:

 One special valve with white flap 

2A

 is used. It

has to be placed in the valve opening shown.
It is recommended to use new gaskets 

3

 when changing

or checking the valves.

Diaphragms

Remove the diaphragm cover 

4

. The diaphragm 

5

 may

then be changed. If fluids have reached the crankcase,
re-grease the pump thoroughly. Check also the drain
hole at the bottom of the pump is not blocked. Reas-
semble with the following torque setting.

If the main ON/OFF valve does not seal properly (drip-
ping nozzles when main ON/OFF valve is closed), the
ball and seat should be checked.
Remove the
2 bolts fixing
the main
ON/OFF-
pressure
valve unit to
the bracket,
unscrew the
union nut
and pull the
valve away
from the
distribution valves.
Check the ball for sharp edges and scratches, and
check the ball seat for cracks and wear - replace if
necessary.
