15.3 Launching the regeneration
The exhaust gas temperature increases to high levels.
When launching the regeneration, an icon representing
the temperature of the exhaust gas is displayed on the
operator display station to warn of the emission of high
temperature gas.
Note
The following phenomena are not faults:
• White smoke can be emitted from the exhaust pipe when the engine is cold or acce-
lerating. The vapour accumulated in the DPF causes the emission of smoke which cea-
ses when the temperature of the exhaust gas increases.
• The exhaust gases cleaned by the catalytic converter on the DPF emit a smell diffe-
rent from that of conventional engines.
• When regeneration is underway, engine noise may change if the engine is idling
with no load.
• When regeneration is in progress, auxiliary regeneration mechanisms can emit
noise during their operation.
15.4 Manual regeneration of the particulate filter
• To perform a manual regeneration:
1. Park the machine in a well-ventilated place.
2. Turn the engine speed setting switch to the slow
positron.
3. Raise the lock lever.
4. Hold the DPF manual regeneration switch in
the ON position for 3 seconds or more to start a
manual regeneration.
• When regeneration starts, the engine speed will in-
crease gradually reach high speed idle to perform the
regeneration.
• During the regeneration, the exhaust gas tempera-
ture icon is displayed on the operator display station.
