HOW TO OPERATE YOUR TRACTOR
Diesel Particulate Filter Regeneration
Regeneration Mode: The exhaust filter
regeneration includes 5 patterns of
regeneration modes according to the
particulate matter (PM) accumulation
amount and operating time.
Self-regeneration and assist regeneration
are carried on automatically, but reset
regeneration, stationary regeneration, and
recovery regeneration are to be performed
manually. When the exhaust filter
regeneration request is shown, always
perform the regeneration manually.
The exhaust filter accumulates PM that
cannot be completely burnt inside the
exhaust filter during regeneration. Because
of this, maintenance is needed.

IMPORTANT:
The reset regeneration must be done
during operation.
If it is not done during operation, the
regeneration condition will not be met, the
regeneration request lamp will stay on, and the
regeneration may not end.
If the reset regeneration does not end, please contact
your purchased dealer.

Note: At reset regeneration, the condition may not
be met when the tractor is stopped or idling.
Run the engine at a rated speed during operation or
traveling. (Even while stopped, by increasing the
engine speed to a rated speed, it will become easier
to regenerate.)
