SELECTIVE CATALYTIC REDUCTION (SCR) - BASIC INSTRUCTIONS
Requirements
The operator must maintain appropriate
DEF/AdBlue® levels at all times. The SCR system is
compatible with up to 7% bio-diesel fuel.
Diesel Exhaust Fluid (DEF)/AdBlue®
refilling
The DEF/AdBlue® tank cap (1) can be identified by
the “blue” color of the cap. A fitting under the cap
prevents the insertion of a diesel fill nozzle.
NOTE: If any DEF/AdBlue® spills or contacts any
surface other than the storage tanks, immediately
clean the affected surface with clear water.
DEF/AdBlue® will cause corrosion on painted and
unpainted metallic surfaces, and may distort some
plastic and rubber components.
It is recommended that DEF/AdBlue® filling
equipment should be used having a fill nozzle/pump
with the correct length and diameter, triggered by the
magnet in the tank filler neck and with overfill flow cut
out.
This will ensure that:
● The screen in the filler neck will not be damaged.
● Impurities are not entering the DEF/AdBlue® tank.
The standardized DEF/AdBlue® nozzle matches
the filler neck diameter.
● The DEF/AdBlue® tank is not overfilled, as the
DEF/AdBlue® pump will stop when the
DEF/AdBlue® tank is full.
● DEF/AdBlue® is not pumped in the fuel tank, as
the DEF/AdBlue® nozzle cannot pump when the
magnet is not sensed.
NOTICE: Refilling with a funnel is not recommended
as this may lead to damage of the screen in the filler
neck.
NOTE: The information above has been provided by
the International Organization for Standardization
(ISO), Document number ISO 22241-4 Diesel
engines - NOx reduction agent AUS 32 - Part 4:
Refilling interface.
Diesel Exhaust Fluid (DEF)/AdBlue®
consumption
NOTE: DEF/AdBlue® consumption is highly
dependent on engine loads, humidity levels,
DEF/AdBlue® fluid concentration, and engine speed.
