15OPERATING THE ENGINE
BHandling Points
C Fuel
Be sure to use Ultra Low Sulfur Fuel (S15).
A Use of diesel fuel other than Ultra Low Sulfur Fuel may
adversely affect the engine and DPF performance.
Use of fuels other than Ultra Low Sulfur Fuel (S15)
may not meet regulations for your region.
C Engine oil
Use DPF-compatible oil (CJ-4) for the engine.
A If any engine oil other than CJ-4 is used, the DPF may
become clogged earlier than expected and the fuel
economy may drop.
BDPF Regeneration Process
This system has "Parked Regeneration" in which the DPF
regenerates while the tractor is parked and "Automatic
Regeneration" which the DPF can regenerate
automatically while working.
When key switch is turned ON, the tractor will be in the
"Inhibit Mode". By pressing the auto regeneration switch,
the mode can be switched to the "Auto Regeneration
Mode".
Choose from them according to your job condition, usage
environment and other factors.
C Parked Regeneration Mode;
When an amount of PM more than specified has built up
in the DPF, the indicator starts flashing to notify the
operator that Regeneration is required. Therefore, park
the tractor in a safe place and carry out the regeneration.
C Auto Regeneration Mode;
Press the auto regeneration switch, and the Auto Mode
is activated.
When an amount of PM more than specified has built up
in the DPF muffler, the DPF is automatically regenerated
whether the tractor is in motion or parked.
For jobs not affected by hot gases emitted out of the DPF
muffler during regeneration, the Auto Mode is advisable.
C Inhibit Mode;
The tractor has been set to Inhibit Mode by default.
Even if an amount of PM more than specified has built
up in the DPF muffler, the DPF does not regenerate.
When the regeneration is needed, the indicator starts
flashing to notify the operator to active either Auto
Regeneration Mode or conduct a Parked Regeneration
Mode, once in a safe area.
For jobs that are done in poorly ventilated area or in area
that may affect plants and animals because of hot gases
that will be emitted, the Inhibit Mode is recommended.
