IMPORTANT:
Dirt/dust, oil, greases, detergents and any chemicals
and natural products must be prevented from entering
the Adblue/DEF tank.
The system will be damaged if dust or dirt enters the
tank clogging the filters in the dosing system.
Keep the tank clean at all times.
®
The AdBlue /DEF-solution is stored in a separate
tank.
Tanks are made of plastic and are available in different
shapes and sizes.
There is a fitting in the tank that comprises a heating
coil (1), a float (2) and a filter (3) on the suction line to
prevent any particles from circulating through the
system and causing disruptions.
The filter must be checked and cleaned as necessary.
There is a drain plug (4) on the bottom of the tank so
that the solution can be emptied when necessary, e.g.
for cleaning.
The tank is fitted with a breather to equalize pressure
changes.
Tank level
®
AdBlue /DEF solution consumption varies during
operations. The level in the tank is shown on the gauge
as a percentage of the total tank volume.
When the level in the tank falls below the limit, the level
sensor in the tank transmits a signal that closes the
injection valve. A fault code is set in the engine control
unit, a warning lamp lights up and a fault message is
shown on the control panel. If AdBlue
not added, injection into the exhaust pipe will cease
and engine rpm and torque will be limited. When
®
AdBlue /DEF is added the fault message is canceled
and the engine is once again able to deliver full power.
Refer to Fault handling, page 58 for further
information.
®
Should the AdBlue /DEF tank become empty during
operations this will not lead to damage to the engine or
