EXPLANATION OF COMPONENTS
REMARK
• The progress of the manual stationary regeneration
performed when soot is accumulated can be checked
by the number of lighting lamps of soot accumulation
level (2). The manual stationary regeneration starts at
soot accumulation level "4" or higher and finishes
when all the level lamps go out.
• The manual stationary regeneration for protection of
the system during cold season may start even when
the soot accumulation level is "0" to "3". In this case,
the soot accumulation level may not decrease, but this
is not a failure. The progress is not displayed on the
monitor during this regeneration. It is completed in ap-
proximately 10 minutes.
• If the accelerator pedal or directional lever is operated,
or the parking brake is released during the manual
stationary regeneration, the regeneration is stopped
automatically. Release your foot from the accelerator
pedal, turn the directional lever to NEUTRAL position
(N), apply the parking brake, and then repeat the pro-
cedure from step 5.
• When the machine needs to be moved during the
manual stationary regeneration, stop the regeneration
temporarily and move the machine, referring to the af-
tertreatment devices regeneration disable and cancel
of regeneration disable procedures described in the
following.
When restarting the manual stationary regeneration,
secure the safety of the machine and around it, then
cancel the regeneration disable.

After the manual stationary regeneration is completed, the screen automatically returns to the standard
screen.
PROCEDURE FOR AFTERTREATMENT DEVICES REGENERATION DISABLE
SETTING
If there is combustible material around the machine and the active regeneration that increases the exhaust tem-
perature must not be performed, the automatic active aftertreatment devices regeneration can be disabled.
Also, the regeneration in progress can be stopped.
NOTICE
Even if the regeneration is disabled, KDPF soot accumula-
tion caution lamp (1) lights up if soot is accumulated and
the manual stationary regeneration is required.
If KDPF soot accumulation caution lamp lights up, move
the machine to a safe place and perform manual stationary
regeneration.
If the operation is continued without performing the man-
ual stationary regeneration, it may cause the failure of
KDPF or the engine.
WHILE REGENERATION IS NOT BEING PERFORMED: SETTING FOR REGENER-
ATION DISABLE
