Checking and adjusting load-sensing leaf-
spring control valve
1. Measure the weight plus load of the rear
axle(s).
2. Check the attachment of the control lever
and its ease of operation.
3. Check whether the correct valve and the
correct springs have been fitted (for
information, see the instruction plate).
4. Check the length of the control lever (see "L"
on the instruction plate).
5. Connect pressure gauge (4) to the test
connection close to connecting point on
the load-dependent control valve (input
pressure).
6. Connect pressure gauge (2) to the test
connection on one of the brake cylinders
(service brake connection) of the rear axle.
7. Make sure that the reservoir pressure is
higher than 8.5 bar throughout the testing
process.
8. Depress the brake pedal until gauge (4)
indicates a reading of 8 bar.
9. Read the brake pressure of the rear axle
from the pressure gauge (2) and check that
this value matches the one listed on the
instruction plate in the table under "delivery
