Air suspension
!
WARNING
Risk of accident due to fully lowered or
raised vehicle!
Failure to set the air suspension to the
"Drive" position before starting off can res-
ult in a risk of accidents due to impaired
driving characteristics or vehicle collisions
in passageways.
► Always move the air suspension into
driving position before driving off. The
only exception is manoeuvring at
walking speed.
CAUTION
Risk of injury due to crushing!
When lowering the trailer, the clearance
under the trailer is reduced. Persons
between the road and vehicle parts can be
crushed and seriously injured.
► Avoid the danger areas.
► When operating the air suspension,
avoid having persons underneath the
trailer.
NOTE
Material damage due to grounding!
On vehicles with a large lifting height, the
ground distance is reduced when reaching
maximum lifting height. The spring ele-
ments on the axle could ground when
manoeuvring and be damaged.
► For vehicles with large lifting heights,
always put the air suspension in driv-
ing position.
KRONE trailers are equipped with an air
suspension system. The vehicle height
(e.g. to adjust it for a ramp) can be adjus-
ted in two ways:
○
Manually
○
Electronically controlled
Also observe the enclosed supplier
documentation.
