• Even just after the regeneration is completed, the soot accumulation level may not be “0”. This is caused by
the accumulated noncombustible material in the exhaust gas and is not a failure.
• Since noncombustible material which cannot be burnt by the regeneration is accumulated in KDPF, the filter
needs to be cleaned or replaced at regular intervals. Ask your Komatsu distributor for cleaning the inside of
KDPF.
• The engine speed or engine sound may change during or after the regeneration. This is caused by the con-
trol for better regeneration and this is not a failure.
• The smell of the exhaust gas is different from that of the conventional diesel engine because of the exhaust
gas filtering function.
• White smoke may be discharged for a short time just after the engine is started or during the regeneration
in the cold season, but this is not a failure.
• Komatsu recommends using Komatsu genuine engine oil for KDPF.
If engine oil other than Komatsu genuine oil for KDPF is used, it may shorten cleaning interval of KDPF
filters, adversely affect the engine such as deteriorated oil may reduce lubricating function, and it may
cause failure.
In addition, the regeneration interval may be shortened and the fuel consumption may increase.
• If the mixing ratio of the bio-fuel in the diesel fuel is high, the regeneration of KDPF may become more fre-
quent.
When the degree of emergency is low
• If the KDPF soot accumulation caution lamp (2) lights up in
yellow (the action level (4): “L01”), the screen (A) is dis-
played first.
• The action level goes out 2 seconds later and the screen
changes to the standard screen (B).
• If the machine is completely stopped, the display switches
to “Aftertreatment Devices Regeneration” screen (C) after
3 seconds only the first time. If, however, the manual sta-
tionary regeneration is not performed, the display returns
to the standard screen (B) after 30 seconds.
Then, if the accumulated soot does not decrease, “After-
treatment Devices Regeneration” screen (C) is displayed
for 30 seconds every 2 hours.
• If the KDPF soot accumulation caution lamp (2) lights up in
yellow, stop the machine in a safe place after finishing the
work and perform the manual stationary regeneration.
