2. Make sure that the DPF-INHIBIT-switch-lamp
is "OFF".
DPF INHIBIT switch lamp is off
Auto regeneration mode is activated.
DPF INHIBIT switch lamp is on
Regeneration inhibit mode is activated.
NOTE :
• When the engine is started, the auto-
regeneration-mode
activated.

3.1.1 PM warning level and required procedures for auto regeneration mode

During auto-regeneration-mode when the PM level has built up in the DPF, the regeneration cycle will begin
automatically. If the regeneration cycle is interrupted or the regeneration conditions are not satisfied, the buzzer starts
sounding and the indicator display changes in response to the PM level in order to prompt the operator to perform the
required procedure listed in the following table.
IMPORTANT :
• Once the regeneration level has been reached, immediately perform the required procedure for
regeneration.
Interrupting the regeneration cycle or continuing operation while ignoring the warning signs may cause
DPF and engine damage.

EXHAUST AFTERTREATMENT DEVICES
• Regeneration-inhibit-mode is activated when
the DPF-INHIBIT-switch is pushed after the
engine is started.
When the regeneration indicator
flashing, a specific amount of PM has built up in the
DPF.
3. Continue to operate the tractor.
The regeneration process will begin automatically.
Make sure that the working place is in a safe area
because DPF and exhaust temperature will rise.
4. When the engine-rpm-increase-indicator
starts flashing, keep on working and increase the
engine rpm until
turns "OFF".
NOTE :
• Even if the
selected, DPF regeneration may not begin
because system requirements have not been
satisfied.
• The engine-rpm-increase-indicator is used
as a guide to satisfy the regeneration
conditions. If the engine load is too heavy,
the engine-rpm-increase-indicator
continue to flash, even though regeneration
system conditions
regeneration may begin automatically.
