Draining the compressed air
tanks
!
WARNING
Risk of accident due to condensation
water!
Condensation water in the compressed air
tank can cause corrosion and affect the
functionality of the brake system and the
air suspension. Frozen condensation wa-
ter can lead to total failure of the brake
system and to serious accidents.
► Check the compressed air tank for the
presence of condensation water.
► Drain any existing condensation wa-
ter.
► Drain existing condensation water
more frequently in case of low or
strongly fluctuating outside temperat-
ures.
The tractor vehicles are fitted with air dry-
ers. This means that condensate in the
compressed air is largely prevented. Dur-
ing cold periods of the year, or when air
humidity is high, condensation water can
still form and collect in the compressed air
tank. The compressed air supply for the
brake system and the air suspension is
stored in the compressed air tanks. Exist-
ing condensation water can be drained us-
ing the water drain valve.

► Push the valve pins of the water drain
valves on all compressed air tanks to
the side until the condensation water is
fully drained.

Brake system

DANGER
Risk of accidents due to non-functional
EBS!
If the EBS plug connection function is not
established, the EBS of the vehicle and
the automatic load-dependent brake
power regulation cannot work. The vehicle
is overbraked and the wheels may lock.
Serious traffic accidents could occur. Driv-
ing without the EBS plug connection is
prohibited by law.
► Only drive with an approved, connec-
ted and functioning EBS plug connec-
tion.
► Always connect the EBS plug connec-
tions between the tractor unit and the
trailer.
► Verify the EBS plug connection via a
system check (the magnetic valves in
the EBS modulator are audibly and
briefly activated and deactivated for 2
seconds after “ignition on”)
► Only use plug connections that com-
ply with the regulations.
► Have the fault immediately repaired
by the nearest contract workshop.

WARNING
Risk of accident due to unharmonised
brake power tuning!
Unharmonised brake power between the
tractor unit and trailer may lead to insuffi-
cient or excessive trailer braking values.
This can cause wear and accidents.
► Monitor the automatic coupling force
control to harmonize the brake power.
► Pay attention to the sticker on the
trailer.
