output and the hose to the washing station.

3. Run the Foam Wash washing programme for this

washing station.

4. Adjust the air dosing valve so that the service tool

pressure gauge reads 0.15 MPa (1.5 bar).

5. End the currently running Foam Wash washing pro-

gramme.

6. Remove the service tool and reconnect the hose to

the washing station to the air distribution block.

7. Repeat the setting of the air dosing valves for the re-
