EXPLANATION OF COMPONENTS
NOTICE
If the work is continued with red KDPF soot accumulation caution lamp (2) displayed, KDPF or the en-
gine can have trouble.
If KDPF soot accumulation caution lamp (2) is displayed, be sure to perform the manual stationary re-
generation.
If the engine is stopped during the aftertreatment devices regeneration, the components may be dam-
aged.
When stopping the engine, stop the aftertreatment devices regeneration first according to "PROCE-
DURE FOR AFTERTREATMENT DEVICES REGENERATION DISABLE SETTING", then stop the engine af-
ter running it at low idle for approximately 5 minutes. Then stop the engine.
REMARK
• If the parking brake lever and work equipment lock lever are set to LOCK position, the manual stationary
regeneration may start automatically to protect the KDPF system.
• If KDPF soot accumulation caution lamp (2) lights up in red, the maximum engine output power and maxi-
mum engine speed are limited to protect the engine and KDPF system.
NOTICE
If the work is continued without performing the manual
stationary regeneration, and the quantity of soot exceeds
the allowable limit, action level "L04" lights up. In this
case, the machine needs to be repaired by your Komatsu
distributor. Also, the maximum engine output power and
maximum engine speed are limited to protect the engine
and KDPF system.
