SWITCHES
5. The manual regeneration symbol stops
flashing and remains lit to indicate that
the engine RPM is automatically
increased and the DPF (1) regeneration
(PM burning) has started.
6. Release the switch. Do not leave the
machine during regeneration.
It takes approximately 25 to 30 minutes,
depending on the ambient temperature,
to complete the regeneration operation.
7. The manual regeneration symbol goes
off to indicate the end of manual
regeneration.
Note:
· Since the exhaust gas is cleaned through
the catalyst fitted inside the DPF, it has a
smell different from that of the conventional
diesel engine.
· In some cases smoke may be emitted from
the tail pipe while the DPF regeneration is
being performed. This is not a failure; it is
due to burning of the particulate matter
(PM).
· It is normal that a sound is produced when
the DPF regeneration is started or
completed; This is to adjust the air-intake
throttle and EGR opening position.
· In some cases the noise associated with
the DPF regeneration operation or cancel
operation may change; this is not a failure.
· The DPF manual regeneration can be
completed faster while the machine engine
is warm rather than cold. Note that the
manual regeneration does not start unless
the coolant temperature is higher than a
set value. The coolant temperature may
increase while manual regeneration is being
performed.
· Since the DPF regeneration is designed to
work only when the accumulated
particulate matter (PM) in the filter exceeds
a certain amount, it will not start otherwise,
even if you attempt to perform manual
regeneration.
• DPF regeneration inhibit (cancel)
To cancel the DPF regeneration currently
being processed (manual or auto), press
the regeneration inhibit symbol side.
The DPF regeneration inhibit symbol
appears on the display, and the
regeneration operation must be performed
again. Start the manual regeneration
procedure from Step (1) above, as soon as
possible. Do not press the DPF
regeneration inhibit switch unless there is a
risk of fire.
To cancel, press the switch again. Turning
the starter switch to OFF will also cancel
the operation.
