Conditions for DPF Regeneration
Danger
Danger
Since it will become extremely hot around the
exhaust outlet during DPF regeneration, do
not perform the regeneration in a location
where fires may occur.
Important
If DPF regeneration is interrupted before it is
completed, the next regeneration may be
requested soon since not all of the PM (soot)
was removed.
Important
Perform DPF regeneration when the engine
sufficiently warmed up.
DPF auto regeneration does not begin
unless both of the following two conditions
are met.
The DPF auto regeneration inhibit switch
is set to the "Auto regeneration mode".
(Auto regeneration inhibit icon is turned
off.)
The coolant temperature is 50 °C or more.
DPF parked regeneration and manual
regeneration do not begin unless all of the
following five conditions are met.
The DPF auto regeneration inhibit switch
is set to the "Auto regeneration mode".
(Auto regeneration inhibit icon is turned
off.)
The parking brake is applied.
The traveling pedal is in the neutral
position.
The throttle opening is 0% (idling).
The coolant temperature is 50 °C or more.
During DPF regeneration, the operation is
canceled if any of the following conditions
occur.
Any condition for starting regeneration is
violated.
The ignition key is switched to the "OFF"
position.

PM Accumulation Level
Level 0
DPF regeneration is not necessary.
Level 1
Danger
Danger
Since it will become extremely hot around the
exhaust outlet during DPF regeneration, do
not perform the regeneration in a location
where fires may occur.
Caution
Normally, set the DPF auto regeneration
inhibit switch to the "Auto regeneration mode".
However, when operating in a location where
fires may occur, set the DPF auto
regeneration inhibit switch to the "Auto
regeneration inhibit mode".
Important
When the system enters the level where DPF
regeneration is required, perform the
regeneration immediately.
Interrupting the regeneration or ignoring the
warning and continuing traveling or cutting
work may cause the engine and DPF to
malfunction.
Important
If the regeneration remains uncompleted even
after 30 minutes have passed since the start
of automatic regeneration in PM accumulation
"Level 1", PM accumulation level enters
"Level 2".
Important
Keep engine rotation at 2200 rpm or more
during auto regeneration.
If auto regeneration continues at lower engine
speed than the specified speed, the engine
and DPF will malfunction.
