SAMPLE PAGES FROM THE MANUAL:
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.
