Bleeding the Oil-Hydraulic
System
See also "Instructions for Use for LPS
Climbing Device and Hydraulics".
In order to ensure a reliable operation of
the system, it must be completely bled
during the initial commissioning on site,
after tubes and hoses have been re-
placed, or after maintenance work has
been carried out on the cylinder. In the
process, the oil level in the hydraulic
pump must always be checked and
topped up as required.
Bleeding
1. Attach hydraulic twin hose (92) on
the hydraulic pump side.
2. Connect the pair of couplings to the
climbing device (90) at the other end.
3. Place climbing device in an upright
position.
4. Completely extend the cylinder to
displace the air pockets on the rod
side. (Fig. D5.11a)
5. Disconnect the climbing device and
short-circuit the hydraulic twin hose.
6. Switch on the hydraulic pump and
flush hydraulic twin hose for approx.
1 minute by operating the hand valve.
(Fig. D5.11b)
7. Disconnect the hose ends from one
another and reconnect to climbing
device.
8. Turn climbing device upside down.
9. Completely retract the cylinder in or-
der to displace the air pockets on the
piston side. (Fig. D5.11c)
10. Disconnect the climbing device and
once again flush the hydraulic twin
hose for approx. 1 minute using a
short-circuit connection. (Fig. D5.11d)
11. Extend and retract the cylinder pair
several times to check synchronisa-
tion.
