DPF Regeneration switch
Automatic Regeneration
The ECU attempts to start Regeneration during
working “Automatic Rege neration” at a proper
moment after determining the moment.
Once automatic Regeneration starts, the high
temperature indicator lamp lights up with a popup
appearing for the operator to notice it.
Display that notifies the operator of automatic Regeneration
If automatic Regeneration is failed due to a low
exhaust temperature, you should perform it after the
vehicle stops. Therefore, it is recommended to keep
the vehicle working as far as possible in order to
ensure automatic Regeneration is fully completed.
While automatic Regeneration is being carried out,
exhaust emissions above 500
°
C may cause fires or
burns.
Setting this switch to position "3" prohibits automatic
DPF Regeneration in an environment subject to dust,
explosion or regulated noise level. At position "3", a
pop-up appears as shown below:
The switch returns to the normal position of "2" after
pressed by the operator to position "1". However, it
does not return when pressed to position "3" and the
operator shall return the switch from position "3".
DPF Regeneration inhibited
If automatic Regeneration is failed, you should carry
it out a while after the vehicle starts working.
A pop-up on the Display warns the operator to
perform DPF Regeneration. (3 warnings: at 10 hrs
remaining, 5 hrs remaining, Immediate)
Exemplary warning – 10 hrs remaining
Limit the engine power and stop the current work
when Regeneration is not used; you will be violating
the exhaust regulations if you do not.
To carry out Regeneration safely, observe the
following steps:
1. Park the vehicle at a safe place. White smoke
can be emitted during Regeneration.
2. Remove the flammable material or stained oil
from exhaust system. High temperature of
exhaust system and gas can cause fire.
3. Engage the parking brake, and make sure the
gear is in neutral.
4. Allow engine to warm up sufficiently; the
Regeneration is not possible in cold condition.
5. After holding down the switch at the “3” position
for three seconds, check that DPF Regeneration
has started.
6. Once Regeneration finishes, the LCD display will
show a notification.
