11. Set the simulated bellows pressure to its
second highest value, as indicated on the
instruction plate.
12. Depress the brake pedal until pressure
gauge (4) indicates a pressure of 8 bar.
13. Read the pressure gauge (2) and check that
this braking pressure matches the pressure
indicated in the table on the instruction plate.
14. If the measured reading is not correct,
depressurise connection (43) and turn the
adjusting bolt (r) using a Torx screwdriver:
- braking pressure too high: screw in the
adjusting bolt
- braking pressure too low: unscrew the
adjusting bolt.
Note:
When depressurising the simulation
connection (pressure gauge 43), the air hose
must remain connected to prevent the
(actual) bellows pressure from accidentally
activating the valve.
The small socket head screw in the centre of
the valve must not be adjusted.
15. If the adjusting bolt (r) has been turned,
repeat the procedure from point 6.
