Engine Exhaust Emission Control System
This machine is equipped with an engine exhaust emission
control system that meets applicable engine EPA/EU exhaust
emission regulations. The owner/operator is responsible for
proper operation and maintenance of the emission controls
system as provided in this manual and the emissions-related
warranty provisions.
The engine exhaust system is equipped with a diesel particulate
filter (DPF). The DPF is an emissions reduction device that
removes diesel particulate matter or "soot" from the exhaust
gases of the diesel engine. The DPF will trap and collect the
particulate matter until it is burned off. The process of burning off
the collected particulate matter is called "regeneration". After the
regeneration process is completed, ash residue will remain and
will need to be periodically removed from the DPF. Ultra Low
Sulfur Diesel fuel and API-CJ-4/ACEA-E9 grade engine oil must
be used with this engine for the emission control system to
function properly.
If you have any questions about the operation or maintenance of
your emission control system, contact your DOOSAN distributor.
WARNING
AVOID DEATH OR SERIOUS INJURY
Exhaust gas temperature and exhaust system components
are very hot during regeneration. This can cause a fire or
burn hazard and result in death or serious injury or property
damage. Keep flammable material and explosive gases
away from exhaust system during regeneration.
