OPERATION EXPLANATION OF COMPONENTS

NOTICE
If the work is continued without performing the stationary
manual regeneration and the quantity of soot exceeds the
allowable limit, action level monitor "L04" lights up. In this
case, the machine needs to be repaired by your Komatsu
distributor. Also, the maximum engine output and maxi-
mum engine speed are limited to protect the engine and
KDPF system.
REMARK
q
Soot accumulation level (4) can be checked with the KDPF
regeneration screen. Press switch F6 on the standard
screen to display the KDPF regeneration screen of the user
menu.
q
Since the soot in the filter of KDPF can be burnt by the high-
performance catalyst and high-temperature exhaust heat,
the soot accumulation quantity may decrease even if the
regeneration is not performed, depending on the operating
condition.
q
Even when the soot accumulation level is low, the auto-
matic regeneration may be performed and the manual sta-
tionary regeneration may be requested to protect the
system. In particular, if engine is kept running with no load,
the regeneration frequency may increase, but this is not
trouble.
q
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 trouble.
q
Since noncombustible matter which cannot be burnt by the
regeneration is accumulated in the filter of KDPF, the filter
needs to be cleaned or replaced at regular intervals. See
"EVERY 4500 HOURS MAINTENANCE (4-10)".
q
The engine speed or engine sound may change during or
after the regeneration. This is caused by the control for bet-
ter regeneration and is not trouble.
q
The smell of the exhaust gas is different from that of the
conventional diesel engine because of the exhaust gas
purification function.
q
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 trouble.
q
Always use Komatsu genuine engine oil for KDPF. If the
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 lubricating function reduction by
deteriorated oil, and it may cause failure. In addition, the
regeneration interval may be shortened and the fuel con-
sumption may increase. For details of the genuine oil, see
"RECOMMENDED BRANDS AND QUALITY FOR PROD-
UCTS OTHER THAN KOMATSU GENUINE OIL (7-8)".
