fully lowered and on the ground.
2.
Clean the line connections and the
surrounding area.
3.
Remove the fuse from the lifting gear.
4.
Remove the shock absorber next to the
cylinder.
If the cylinder is located on the vehicle’s left,
the linkage of the load-sensing
brake-control valve should also be
removed.

Remove the lines from the lifting cylinder.
Note: the line attached to line connection A
of the pump unit may retain a residual
pressure.
Wait for approx. 5 minutes after the trailing
axle has been lowered before disconnecting
the lines.
Collect the oil coming from the line.
Plug the openings.

Disconnect the lines of the central
lubricating system, if applicable.
7.
Remove the pin (4) connecting the cylinder

The cylinder will now point downwards,
causing part of the oil in the cylinder to flow
out.

the cylinder (3) from the chassis bracket (1).
Collect the oil still present in the cylinder.
