7.4 Parking the trailer safely
WARNING
Risk of accident due to instability and
rolling away!
Unintentional trailer movements can
cause serious injury and property dam-
age.
► Secure the trailer against rolling away
by applying the parking brake.
► Use the wheel chocks to prevent the
trailer from rolling away.
► Park the trailer on a solid surface to
avoid sinking in or tipping.
► Align the tractor unit and trailer behind
each other in a straight line.
► Load and unload the trailer such that
traffic hazards are ruled out.
► Be mindful of the trailer's stability
when loading and unloading while un-
hitched. If necessary, use additional
supports.
INFO
Ramp adjustments can only be made in
the coupled (saddled) condition, with ad-
ded compressed air. If rear braces have
been factory-fitted to the rear of the trailer,
adjust these according to the height of the
ramp.
► Drive the trailer onto firm and level
ground.
► Apply the parking brake (see "5.9.2
Parking brake", pg.37).
► Use wheel chocks to prevent the trailer
from rolling away (see "5.1 Using wheel
chocks", pg.22).
► Extend the landing leg winches (see
"5.2 Landing leg winches", pg.23).
► Extend the rear braces, if present (see
"5.3 Rear braces", pg.25).
► Disconnect the supply and control con-
nections (see "5.6 Supply and control con-
nections", pg.31).
► Unhitch the trailer from the tractor unit.
► For longer parking periods and when
loading the ramp while parked, lower
the air suspension (see "5.10 Air suspen-
sion", pg.41).
ü The trailer is safety parked.
7.5 Driving with open doors
Driving with open doors can be necessary
in exceptional cases.
► Additionally secure open doors to pre-
vent them from moving uncontrollably
(tension strap).
► Mark excessive lengths at the rear of
the vehicle.
► Stabilise the superstructure with cross-
bracing (max. 20 dN).

The opened doors give the trailer an ex-
cess width. Load-securing certificates be-
come invalid.
