The DPF indicator will remain off when DPF
regeneration is completed. Allow the engine and the
DPF time to return to normal operating temperature
before stopping engine. At any time during the parked
procedure, the process can be cancelled .
Avoid disabling the cleaning procedure unless
absolutely necessary. Repeated disabling or ignoring
prompts to perform a manual/parked cleaning
procedure will cause additional engine power
limitations and can eventually lead to dealer required
service. Utilize Exhaust Filter Cleaning AUTO mode to
avoid additional service.
IMPORTANT: The operator will be informed by the
operator warning system when the emission control
system does not function correctly and/or an engine
malfunction is detected by the engine control unit.
Ignoring the operator warning signals will lead to an
emission related derate, resulting in an effective
disablement of non-road mobile machinery operation.
Three indications for DPF regeneration and
warnings are present on the instrument cluster.
DPF REGENERATION
Ÿ Servicing machine or attachments during exhaust
filter cleaning active regeneration of DPF can
result in serious personal injury. Avoid exposure
and skin contact with hot exhaust gases and
components.
Ÿ During auto or stationary exhaust filter cleaning
operations, the engine will run at elevated idle and
hot temperatures for approximately 30 minutes.
Exhaust gases and exhaust filter components
reach temperatures hot enough to burn people,
ignite, or melt common materials.
Ÿ If the machine is not in a safe location for elevated
exhaust temperatures, move the machine to a
safe location and check for adequate fuel level
before beginning the exhaust filter cleaning
process. Any PTO driven devices (if equipped)
should be powered off or disconnected.
Note : If the machine is not able to be moved into a
safe location, the operator should temporarily
disable auto exhaust filter cleaning by pressing
DPF switch in position 2 as mentioned in section
3.14) If the machine is located in a safe location,
the auto mode should always be enabled, the
switch should be in OFF condition.
Failure to follow the approved ash removal methods
may violate state and local hazardous waste laws,
along with damage to the DPF resulting in potential
denial of the diesel exhaust filter emissions warranty. It
is strongly recommended you take the DPF to an
authorized Farmtrac service location or other qualified
service provider for servicing.
CAUTION : Hot surface indication is present
on the muffler. Do not touch or stand near it while
operating the tractor.
4.2.4. Manual Regeneration
Manual Exhaust Filter Cleaning is an automated
process initiated at the request of the operator. This
process allows the system to clean the exhaust filter
when DPF cleaning signal starts blinking on
dashboard. During the process the engine speed will
be controlled by the ECU and the machine must
remain parked to complete the procedure. Time
required for the Manual/Parked regeneration process
is dependent upon the level of exhaust filter restriction,
ambient temperatures, and current exhaust gas
temperature.
