ATTENTION!
Please note the following when installing electric
cables and pneumatic hoses:
The electric cables and air hoses must be installed
at an adequate distance from moving parts of the
vehicle. If necessary, provide electric cables with
corrugated heat protection tubing or an anti-chafe
guard.
Lay electric cables and pneumatic hoses in such a
way that they do not kink or chafe.
The electric cables and air hoses must be secured
using cable ties (e.g. to the vehicle wiring harness).
Perform work on the compressed air system only
when it is not under pressure.
Comply with the fitting guidelines of the vehicle
manufacturer.

Safety instructions for operation
Before commencing any journey and each time a trailer is coupled
up, check that the equipment is in good condition and the locking
mechanism is secure. Only drive the vehicle with the locking mech-
anism locked and secured.
WARNING!
If the fifth wheel coupling is not correctly closed and
secured, the semi-trailer may become detached. This
can cause an accident, injuring you and others. After
coupling, always check that the fifth wheel coupling is in
good condition and securely locked. Always carry out a
pre-departure inspection, even if "Fifth wheel coupling
closed" (green) is shown on the display. The JOST KKS is
only an assistance function that helps you with the cou-
pling and uncoupling of semi-trailers.
