D7 Remedial measures for malfunctions
Venting the system
The system must be completely vented
after initial commissioning on site, after
hydraulic hoses have been replaced, or
after maintenance work has been car-
ried out. The oil level in the hydraulic
unit must be checked throughout this
process and topped up as required.
The flushing time for each 20 m single
hose length is 1 minute (DN 08).
Venting
1. Flush hoses using short-circuit con-
nections. (Fig. D7.02)
2. Connect the cylinder in horizontal po-
sition and extend fully.
3. Uncouple the cylinder and flush hos-
es once again using short-circuit con-
nections.
4. Connect the cylinder in horizontal po-
sition and extend fully.
5. Uncouple the cylinder and flush hos-
es once again using short-circuit con-
nections.
6. Connect the cylinder and extend and
retract several times.

The flushing time required for each
20 m single hose length is approx.
1 minute (DN 08).
Venting during hose replacement
1. Detach old hose.
2. Connect new hose on the pump
side.
3. Flush hoses using short-circuit con-
nections.
4. Connect the cylinder in horizontal po-
sition and extend fully.
5. Uncouple the cylinder and flush hos-
es once again using short-circuit con-
nections.
6. Connect the cylinder in horizontal po-
sition and extend fully.
7. Uncouple the cylinder and flush hos-
es once again using short-circuit con-
nections.
8. Connect the cylinder and extend and
retract several times.
Extend and retract the cylinder several
times in order to check for leakage and
synchronisation. In the process, extend
and retract the cylinder at maximum
pressure for a longer time in the end
positions.
Manual end position compensation
If the synchronisation deviation is too
great when under load, then carry out a
manual end position compensation
with the aid of a short-circuit connec-
tion.
