Manual Regeneration Procedure

When manual regeneration is needed, screen (1) as
shown in the right will be displayed. When this screen (1)
is displayed, you need to perform manual regeneration.
Before starting manual regeneration, be sure to check the
following.
If the rear view camera is equipped on the machine and the
camera is enabled, screen (1) is displayed only when the
pilot control shut-off lever is in LOCK position.
 No person is present around the machine.
 Keep flammable materials away from the muffler.
 Fuel level alarm is not lit.
 DEF/AdBlue® level alarm does not light.
1. Park the machine in a safe place. Lower the front
attachment onto the ground.
2. Pull the pilot control shut-off lever to the LOCK position.
3. Set the engine control dial to slow idle.
4. Push aftertreatment device regeneration switch (2).
5. When pushing aftertreatment device regeneration
switch (2), screen (3) as shown in the right will be
displayed and the manual regeneration starts. A
bar graph on screen (3) shows the progress of the
regeneration process.
IMPORTANT: The manual regeneration does not start
unless the pilot control shut-off lever is in the LOCK
position and the engine control dial is in slow idle.
When touching the pilot control shut-off lever or the
engine control dial during manual regeneration, the
regeneration process is aborted. When the process is
aborted, start over again.
6. When the manual regeneration is complete, the
message "Regeneration Has Completed." is displayed.
If "Regeneration Has Failed." message is displayed, start
over the manual regeneration process once again.
Failure of the regeneration process may happen in
conditions other than those mentioned above (such as
a malfunction of a sensor that affects regeneration, or at
low ambient temperature).
