About Aftertreatment Device

The aftertreatment device removes particulate matter (PM)
and nitrogen oxide (NOx) from the exhaust gas. Follow the
instructions below to prevent the aftertreatment from being
damaged.

WARNING:
 Exhaust gas from the aftertreatment device, muffler,
exhaust piping and tail piping becomes hot during
and just after engine running and regeneration of
aftertreatment device. Pay attention not to let your
skin contact any part of exhaust system or hot gas
from the exhaust piping, as it may cause severe
burns.
 If flammable materials such as dead leaves or paper
scraps are around the aftertreatment device, they
may cause a fire.
 To avoid burns, stop the engine and make sure
the engine has sufficiently cooled down before
performing maintenance.
IMPORTANT:
 Be sure to use fuel that complies with JIS K-2204,
EN-590 or ASTM D-975 that contains 15 ppm or
lower sulfur. If the fuel described above is not used,
exhaust gas that exceeds regulation values may be
discharged and serious engine problems may occur.
 Refill DEF/AdBlue® which meets Japanese Industrial
Standards (JIS) or International Organization for
Standardization (ISO). If improper liquid (diesel oil,
kerosene or gasoline) is refilled in the DEF/AdBlue®
tank, fire or system failure may result.
 Use only genuine Hitachi engine oil. Using engine
oil other than Hitachi genuine oil may result in
malfunction of the aftertreatment device.
 Do not mix poor quality diesel fuel, drainage
agents, fuel additives, gasoline, kerosene, alcohol,
or any other type of lubricating oil with specified
diesel fuel. Improper fuel usage may deteriorate
performance of fuel filters, can cause problems in
the lubricated parts of the injector. It can also affect
the engine parts and aftertreatment device, leading
to malfunction.
