NOTE:
 The auto-regeneration is performed 30 hours after the
previous regeneration. The auto-regeneration may start
during operation of the machine; you can continue
to operate the machine. The engine sound and/or the
machine response to the operation of control levers may
change when performing the auto-regenerration; this is
not a malfunction.
 Do not stop the engine during regeneration unless
absolutely necessary.
When the manual regeneration switch is pushed during the
auto-regeneration process, the message "Minimal Exhaust
Restriction. Exhaust Filter Cleaning Not Available." will be
displayed on monitor (2).
Depending on the operating conditions of the machine,
the regeneration may not be completed. In this case,
an aftertreatment device regeneration request will be
displayed on monitor (2). Immediately perform manual
regeneration following the procedure.
This mark indicates that the aftertreatment device
regeneration is inhibited. Regeneration will not be
performed while this mark is lit.
IMPORTANT: Set aftertreatment device regeneration to
the inhibited position while operating the machine
in an environment with materials that could be
flammable. (Refer to the page 1-55)
