DPF
About DPF
The DPF is a purifying filter that collects PM
(soot) from exhaust gas.
When a certain amount of PM (soot) has
accumulated, DPF regeneration must be
performed automatically or manually in order to
restore the filtering function.
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.
Caution
Do not use "DPF Auto Regeneration Inhibit
Switch" and "DPF Parked Regeneration
Switch" during back lapping.
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
Do not repeat unnecessary regeneration or
interrupting regeneration.
If repeating them, the measured level of
engine oil may increase since the engine oil is
mixed with a slight amount of fuel,
accompanied by quality degradation.
Important
Perform DPF regeneration when the engine
sufficiently warmed up.
DPF regeneration is burning PM (soot)
collected in DPF with the exhaust temperature
heated up to high temperature by the engine
ECU control of intake air mass and fuel
injection.
Automatic 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.
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 can cause the
engine and DPF to malfunction.
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.
Important
If auto regeneration is performed during
backlapping operation, the auto regeneration
may result in failure.
When auto regeneration starts during
backlapping operation, stop backlapping
immediately and keep auto regeneration
activated until it is completed.
Automatic regeneration is the automatic
control of increasing the exhaust temperature
for DPF regeneration.
You can continue to use this machine for
traveling and cutting work during DPF
regeneration.
You can operate this machine to perform
the regeneration. (The fault diagnostic tool
is not required.)
