To Perform an Exhaust System
Cleaning
1. Park the machine in a safe location
where the exhaust pipe outlet will not
face any combustible surface.
2. Engage the parking brake.
3. With the engine running and at idle,
press the Manual Regen Button (located
on the Machine Display - Machine Diag-
nostics Page).
NOTE: When the cleaning event is
activated, engine speed may
increase and the HEST Indicator
Lamp (located on the Machine
Display) may illuminate and the
Exhaust System Cleaning Indicator
Lamp will flash.
4. Monitor the machine and surrounding
area for safety.
NOTE: If the machine needs to be used or
moved, stop the stationary cleaning
event by increasing the Throttle
Switch (located near the Hydrostatic
Drive Control Handle).
5. When the Exhaust System Cleaning is
complete, the engine will return to nor-
mal idle speed and the HEST and
Exhaust System Cleaning Indicator
Lamps will turn off.

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.
Excessive use of the Exhaust System
Cleaning Switch in the STOP position
will result in the need for more frequent
stationary exhaust cleaning events.
•
Stop Engine Indicator Lamp (if
equipped)
- Illuminates when
continued operation could result in
damage to the exhaust system. Shut
down the engine as soon as it is safe to
do so and call for service to avoid
damage to the exhaust system.
