4. Tips on diesel particulate filter
(DPF) regeneration
• Operation
The
higher in speed or load the engine operates,
the higher the exhaust temperature rises. As a
result, particulate matter (PM) inside the DPF is
consumed, therefore the regeneration process
occurs less frequently over time.
The lower in speed or load the engine operates, the
lower the exhaust temperature. Accordingly, less
particulate matter (PM) inside the DPF is
consumed, therefore more accumulation of PM will
occur, which requires frequent regeneration,
therefore avoid prolonged idling if possible.
• Necessary conditions for regeneration
When all of the following conditions are satisfied,
the regeneration process will commence. If one of
the following conditions is not met, the regeneration
cycle will be interrupted:
– The engine coolant temperature
– The DPF temperature
– The engine speed is around 1200 rpm or
higher.
• Usually it takes 15 minutes to 20 minutes to
complete the regeneration cycle.
Actual regeneration time may depend on ambient
temperature, exhaust temperature, and engine
speed.
• It is recommended to perform the regenerating
while the engine is warm.
• Do not unnecessarily start and interrupt the
regeneration process. Otherwise, a small amount of
fuel becomes mixed with the engine oil, which
degrades the oil quality.
• While the DPF is being regenerated, the air-flow
rate of engine is automatically limited to keep up
the exhaust temperature. Because of limit of the air-
flow rate of engine, the engine may sound
differently, but this sound is normal for this engine.
• Just after the regeneration has ended, the DPF
muffler remains hot. It is advisable to keep the
engine running for about 5 minutes to allow cooling
of the exhaust components.
STARTING THE ENGINE
1. Activate
the hydraulic-lock-switch by pressing
forward.
(1) Hydraulic lock switch (2) Hydraulic lock indicator
2. Insert
the starter key into the starter switch and turn
it to the [RUN] position.
(1) Starter switch (A) STOP
(B)
RUN
(C) START
The glow-plug-indicator will light up while the
engine
is preheated and will go out automatically
after preheating is finished.
3. Make sure that the and marks appear on
the instrument panel.
If
the
and marks
do not appear, the system
is malfunctioned. Contact your local dealer.
