Periodically check the distribu-
tion valves for proper sealing.
Do this by running the sprayer
with clean water and open all
distribution valves.

Cautiously remove the clip 

A

and pull out the hose 

B

 for the

pressure equalisation device.
When the housing is drained,
there should be no liquid flow
through the pressure equalisa-
tion device. If there is any
leakage, the valve cone 

E

must be changed.

Remove the clip 

C

 and lift the

motor housing off the valve
housing. Then unscrew the
screw 

D

 and replace the valve

If it becomes difficult to build up sufficient pressure or if
pressure fluctuations occur, it may be necessary to
renew cone and cylinder. A HARDI kit is available for this
purpose. Ref. no. 741293.

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 

A

 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.
