EXPLANATORY NOTES ON THE MAINTENANCE ACTIVITIES
Inspection and adjustment
6. Set the simulated bellows pressure at its
highest value, as indicated on the
instruction plate. Depress the brake pedal
until pressure gauge (4) indicates a
pressure of 6 bar.
Read off pressure gauge (2) and check
whether this braking pressure matches the
pressure shown in the table on the
instruction plate.
If the measured value is incorrect, the value
of L2 should be altered.
Before attempting to change L2, first make
all connections pressureless.
- braking pressure too high: shorten L2
- braking pressure too low: extend L2
7. Repeat the procedure described in point 6
until the measured brake pressure reading
is within the tolerance limits.
8. Set the simulated bellows pressure to its
second lowest value, as indicated on the
5
instruction plate. Depress the brake pedal
until pressure gauge (4) indicates a
pressure of 6 bar.
Read off pressure gauge 2 and check
whether this brake pressure matches the
pressure indicated in the table on the
instruction plate.
If the measured value is incorrect, the value
of L1 should be altered. This is possible
without removing the spring.
Insert a Philips screwdriver of sufficient
length into the hollow adjusting screw.
Before attempting to change L1, first make
all connections pressureless.
- braking pressure too high: extend L1
- braking pressure too low: shorten L1
9. If L1 has been changed, repeat the
procedure from point 6.
