SCX550-3 ECOLOGY

The highest level of clean performance.
Environmentally-friendly design to redefine mankind and society.
It is fitting that the most advanced technology is installed in a machine designed to redefine the future of society.

The SCX550-3 brings together a new cleaner running engine and advanced control system (ECO winch mode, auto idle stop function)for energy-efficient operation. Compliant with EU Stage IV exhaust gas emission regulations, the SCX550-3 also offers
exceptional fuel efficiency and outstanding operation and control.

DPR + Urea SCR

Urea tank

DPR + Urea SCR system
A DPR (muffler filter) and Urea SCR system are installed as the exhaust gas aftertreatment
device. The initial muffler filter reduces PM emissions, while the secondary Urea SCR system
reduces NOx emissions. The Urea SCR system injects AdBlue® (urea fluid) into the exhaustgas to break down NOx gases into harmless water and nitrogen via a chemical reaction.
Treating the NOx in the exhaust helps to maintain the engine’s high combustion efficiency,
which increases its fuel efficiency and power output.

Precautions with the new clean engine● Always use diesel for the fuel, specified lower ash
oil (DH-2 <JASO>, CJ-4 <API> class) for the engine
oil, and specified engine coolant. The DPR + Urea
SCR System may undergo automatic regeneration(cleaning) to maintain its performance level.

AdBlue® is a registered trademark of the German Association of the Automotive Industry.

on crane conditions

What is AdBlue®?
The trademark of a high-quality urea aqueous
solution standardized in Europe for using the
Urea SCR System.

Customers®

AdBlue® is a registeredtrademark of theGerman Association of theAutomotive Industry.

Reﬁlling frequency

Once per two refuelings
The SCX550-3 requires AdBlue® to be refilled once
every two times the machine is refueled.
(AdBlue® consumption may vary slightly depending on operating conditions)

Precautions with machines installed with the Urea SCR System

To ensure that the machine can be used safely and smoothly, use AdBlue ® aqueous solution (or a urea aqueous solution that complies with
JIS or ISO standards). Using a non-standard aqueous solution or diluting the solution before use may cause mechanical problems.
Malfunctions arising from the use of non-standard aqueous solutions are not covered by the HSC warranty service.
● The remaining AdBlue® level can be checked during work on the monitor display (Moment
Limiter) in the cab. A warning is displayed on the monitor when the remaining level becomes low
or there is an issue with quality. ● The engine power output will be limited if the remaining
AdBlue® level falls below the minimum level or there is an issue with quality, so be sure to plan
refills in advance. ● The Urea SCR System is designed exclusively for the machine, and must not
be used for any other purpose. ● Rinse with water any solution that comes in contact with skin.
● When storing the solution, always use sealed containers and store at room temperature in awell-ventilated location out of direct sunlight. When carrying the solution, always use thecontainer that the solution was purchased in, or other specified container. ● The Urea SCR
System includes a heater function, however sufficient care must be taken to prevent freezing
when the solution is stored in cold regions (freezing temperature: -11°C) ● Read the instruction
manual for more details.
