CATALYST-CONTAINING DIESEL-PARTICULATE-FILTER (DPF) DEVICE

EXHAUST AFTERTREATMENT DEVICE

CATALYST-CONTAINING
DIESEL-PARTICULATE-FILTER
(DPF) DEVICE
The catalyst-containing-DPF-device has the following
two functions.
• Reducing certain emissions, like hydrocarbon (HC)
and carbon monoxide (CO), to harmless carbon
dioxide (CO ) and water.
2
• Trapping and eliminating PM (particulate-matter)
through the filter at the same time.
To meet EPA regulations, it is necessary to service the
DPF, such as renewing or cleaning the filter at regular
intervals.
Be sure to carefully read the following items before
using the machine. The machine owner and operator
are responsible for using the catalyst-containing-DPF-
device correctly to protect the environment and to
prevent damage to the DPF, and comply with federal
and state regulations.
Use instructions
IMPORTANT :
• If you fail to use the specified fuel or engine oil,
the cleaning interval of the DPF cannot be
secured and the DPF will clog after a shorter
operating time than expected.
The cleaning interval of the DPF
• Fuel
Be sure to use the following fuel.
Use of other diesel fuel other than the following fuel
may adversely affect the engine and the emission-
control-device and may damage them.
Fuel ULTRA LOW SULFUR FUEL (S15)
• Engine oil
Use the following engine oil.
Engine oil DPF-compatible engine oil (CJ-4 or CK-4)
Any unspecified oil may damage the DPF earlier
than expected and lower fuel economy.
Prohibited unnecessary idling
Generally speaking, the lower the engine rpm is, the
lower the exhaust gas temperature is. It is more difficult
to burn PM (particulate-matter) in the DPF at low rpm.
With this in mind, do not keep the engine idling
unnecessarily.

EXHAUST AFTERTREATMENT DEVICE
If you leave the machine with the engine running, to
protect the DPF, the engine may automatically stop.
DPF regeneration system
On the Kubota SSL, the ECU prompts the DPF-
regeneration cycle. When starting the engine, auto-
regeneration-mode is set by default. When all the
conditions are met, regeneration automatically starts,
unless the inhibit switch is engaged.
REGENERATION OF DIESEL-
PARTICULATE-FILTER (DPF)
WARNING
To avoid personal injury or death:
• When the DPF is in the regenerating mode, the
exhaust gas and the DPF muffler become hot.
During the DPF regeneration, take into account
that the DPF muffler will be very hot and keep
the machine away from other people, animals,
plants, and flammable material. Also keep the
area near the DPF muffler clean and away from
flammable material.
• Do not leave the
regeneration.
Indicator symbol and buzzer indicate the DPF level of
PM during operation of the machine.

NOTE :
• During DPF regeneration cycle, keep the
surrounding environment in mind. Do not allow
the ambient temperature to rise excessively due
to heat from the DPF regeneration. If the
ambient temperature rises excessively, activate
the inhibit switch.
