Setting of steering pressure
21.Connect the manometer to the test outlet (9) on the priority
valve H10. Turn the steering wheel to max wheel deflection
and rev up the engine to 1200 rpm. Check that the pressure
reading corresponds to the hydraulic plate.
22.Adjust if needed with the adjusting screw (10)
Checking of accumulator charging pressure
23.Allow the engine to idle.
24.Connect the manometer to the test outlet (11) on the accumu-
lator charging valve H21.
25.Close the accumulator evacuating valve.
26.Check that the accumulator charging starts at 15 MPa and
stops at the pressure stated on the hydraulic plate.
27.Adjust if needed with the adjusting screw (12)
Checking of servo pressure
28.Connect the manometer to the test outlet (13)
29.Check that the pressure reading corresponds to the hydraulic
plate. The pressure is not adjustable.
