the Manual Regen Button (located on the
Machine Display - Machine Diagnostics
Page).
NOTE: When the cleaning event is activated,
engine speed may increase and the

Exhaust System Cleaning Stop
Indicator Lamp
- Illuminates when the
Exhaust System Cleaning Switch is in
the STOP position, preventing a
cleaning event. This switch should be
used only when high exhaust
temperatures present a hazard.
