7 - MAINTENANCE
Selective Catalytic Reduction (SCR) system
Requirements
The operator must maintain appropriate Diesel Exhaust Fluid (DEF)/AdBlue® levels at all times. No additional main-
tenance is required.
NOTICE: Prolonged idling of the machine with no load for more than 6 h will cause damage to the SCR catalyst.
NOTE: See your CASE CONSTRUCTION dealer for replacement components and cleaning agents.
CASE CONSTRUCTION recommends using CASE AKCELA UNITEK NO. 1™ SBL CJ-4 . Optionally, CASE
AKCELA NO. 1™ ENGINE OIL (CI-4) can be used. See [**Link to specifications section**] for specific lubrication
oil temperature charts, maximum lubrication oil consumption ratings, and fuel requirements. Your SCR system is
compatible with up to
20 % biodiesel fuel.
Diesel Exhaust Fluid (DEF)/AdBlue® refilling
The DEF/AdBlue® tank is located on the left-hand side of
the machine, next to the diesel filling port.
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.
NOTICE: 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 com-
ponents.

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: If a warning light has been triggered for low or empty DEF/AdBlue®, the system must be reset by cycling
the key switch OFF then ON after refilling the DEF/AdBlue® tank.
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), Docu-
ment 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 concen-
tration, and engine speed. The “typical” consumption is only a guideline to verify proper function of the SCR system.
CASE CONSTRUCTION recommends to fill the DEF/AdBlue® tanks at every fuel refilling interval.
