Exhaust gas aftertreatment
Cleanliness is very important when working on
the reductant circuit. Clean thoroughly around
all parts to be dismantled to prevent dirt from en-
tering the system.
When working on the exhaust gas aftertreatment
management system, the reductant connections
may only be lubricated with soapy water or with
distilled water with a 3% urea mixture. Any oth-
er types of lubricants may block and damage the
components in the exhaust gas aftertreatment
management system.
Reductant causes certain metals to corrode. Al-
ways rinse away reductant spillage on connec-
tions and other parts with lukewarm water to
prevent corrosion. If reductant seeps into electri-
cal connections or electrical cables, these must
be renewed.
When the engine is running, the exhaust system
parts can reach such high temperatures that there
is a risk of personal injury. Make sure that the
temperature has fallen to a suitable level before
starting work.
A P3 type respiratory protection/filter mask,
goggles and gloves should be used for any work
where there is a risk of exposure to hazardous
particles from the particulate filter. Safety clear-
ance for unprotected people is 3 m.
Any particles must be removed with a vacuum
cleaner to minimise exposure. The vacuum
cleaner must be equipped with a HEPA filter that
can filter out particles down to a particle size of
0.3 µm.
To avoid ingestion, do not eat, drink or smoke
while work is in progress. Make sure you clean
your hands after working on the particulate filter.
The oxidation catalytic converter, the particulate
filter and the SCR catalytic converter contain
precious metals and must be processed in com-
pliance with local regulations.
