Stationary Exhaust System Cleaning (Non-Mission)
If the in-mission cleaning process was not successful, the Selective Catalytic Reduction
(SCR) Indicator (
2
) will illuminate to indicate a non-mission cleaning process is required. A
50 hour period is available to complete the non-mission cleaning process.
1. Move telehandler to an area free of flammables and people that could be exposed to
hot exhaust.
2. Shift transmission to neutral, retract and lower boom and engage park brake.
3. When exhaust system cleaning begins, the HEST (

) and Do Not Turn Off Engine (
3
)
indicators will illuminate. Do not turn off engine.
4. Do not press accelerator pedal or other controls during exhaust system cleaning.
5. SCR indicator (
2
) flashes during cleaning. Stationary exhaust system cleaning takes
approximately 30 to 60 minutes.
Note:
Stationary exhaust system cleaning will stop and may be incomplete if any
controls are inadvertently moved or activated. If stationary exhaust cleaning is
interrupted, HEST (
1
) indicator will turn off and SCR Indicator (
2
) will stop blinking and
illuminate solid. To restart stationary exhaust system cleaning, depress service brake and
disengage park brake. Return to step 1 and repeat process.
6. Stationary exhaust system cleaning is complete after HEST, SCR and Do Not Turn Off
Engine indicators turn off.
If stationary exhaust system cleaning is not completed within the 50 hour period, SCR (
2
),
System Distress (
4
) and Engine Fault Warning (
5
) indicators will illuminate. A torque
derate is initiated.
If stationary exhaust system cleaning is not completed within the next ten hours, SCR (
2
),
System Distress (
4
), Engine Fault Warning (
5
) and Engine Fault Critical (
6
) indicators will
illuminate. Engine is placed in idle-lock until resolved. Contact the local dealer or engine
manufacturer.
