D5.2 Venting the system
Venting during hose replacement
1. Detach old hose.
2. Connect new hose on the hydraulic
pump side.
3. Connect coupling pair at other end.
Short-circuit connection (Fig. 59)
4. Switch on hydraulic pump.
5. Push hand valve upwards. Hose is
flushed for approx. 1 minute.
6. Disconnect hose ends from one
another.
7. Connect cylinder according to the
circuit diagram.
8. Extend and retract the cylinder pair
several times in order to check the
synchronisation.
9. Vent cylinder if required – see
previous section “Venting during
initial commissioning”.
Extend and retract the cylinder several
times in order to check for leakage and
the synchronisation. In the process, run
at maximum pressure for a longer time
in the end positions.
D5.3 Carrying out a reference run
Carry out a reference run if there is any
synchronisation deviation in a cylinder
pair.
1. Extend both cylinders until the climb-
ing pawl or piston claw engages the
climbing rail. The piston of the non-
engaged climbing device moves very
slowly (the leak oil in the flow divider
allows end position compensation).
2. Then move both cylinders against stop
for approx. one minute.
Carry out this operation after each climb-
ing procedure in order to eliminate the
standard deviations of the flow divider.
Manual end position compensation
If synchronisation deviation is too large
when under load, then carry out a
manual end position compensation with
the help of a short-circuit connection:
