Automatic Regeneration - Hitachi ZW 550-6 Operator's Manual

Automatic Regeneration

White deposition may accumulate inside the aftertreatment
device. An automatic regeneration (Auto-regeneration) mode
is designed to automatically clean the aftertreatment device
at regular intervals. The auto-regeneration may start during
operation of the machine; you can continue to operate the
machine. (Refer to 1-35).
f
NOTE:
 Usually, auto-regeneration starts after the previous
regeneration at regular intervals (either auto or manual).
 If auto-regeneration interval becomes shorter, consult your
authorized dealer.
Auto-regeneration may be "terminated" early (inhibited) when
in the presence of flammable materials, such as flammable
airborne debris, wood dust, grain dust, dried leaf debris, or
other flammable risks.
However, when "early termination" (inhibiting regeneration)
happens often, the system will sense this and eventually call
for a manual regeneration using manual regeneration switch
(1). The regeneration request symbol will show, indicating that
manual regeneration is required. Refer to page 1-37 for further
information.
f
NOTE:
 The auto-regeneration may be terminated depending on
the machine operating condition.
 Do not stop the engine during regeneration unless it is
absolutely necessary to do so.
