hitachi — Automatic Regeneration

OPERATOR'S STATION 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. 1 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: MNEC-01-041 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. 1-5
