Manual Regeneration
DO NOT leave Telehandler unattended during manual
regeneration.
The manual regeneration should be performed by qualified
personnel.
This procedure requires the engine to run
continuously for 15 to 30 minutes. The Telehandler cannot be
operated during this procedure.
1.
Stop the Telehandler and set the parking brake (Do
not release the parking brake until the regeneration is
complete).
2.
Verify the engine is at low idle.
3.
Verify the fuel level is sufficient for 30 minutes of operation.
4.
Verify the accelerator pedal is not depressed.
5.
Press the Manual Regeneration Button.
6.
The engine speed will increase to 1000 RPM and the High
Exhaust System Temperature (HEST) indicator will be
displayed.
7.
Do not press the accelerator pedal.
8.
Allow the manual regeneration to complete without
interruption.
9.
Engine speed will decrease to low idle and High Exhaust
System Temperature (HEST) indicator will turn off.
10. The manual regeneration is complete.
11. Turn the engine off and re-start to reset the Exhaust
Aftertreatment System.
Engine Diagnostic Fault Codes
The electronic engine control system displays and records
certain detectable fault conditions. These failures are dis-
played as fault codes, which make troubleshooting easier.
The fault codes are retained in the ECM.
There are two types of diagnostic codes:
•
Engine electronic control system fault codes inform the
operator that there is a problem with the control system
that requires troubleshooting.
•
Information and engine protection fault codes inform
the operator that the control system has detected an
engine condition outside the normal operating range.

Caution
All fault codes recorded will either be active (fault code is
presently active on the engine) or inactive (fault code was
active at some time, but is not presently active).
The STOP ENGINE lamp is red and indicates the need to stop
the engine as soon as it can be safely done. The engine must
remain shut down until the engine can be repaired.
When illuminated, the yellow "WARNING" or "CHECK ENGINE"
lamp indicates that the engine is in need of repair at the first
available opportunity.
Another function of the WARNING or CHECK ENGINE lamp
(yellow lamp) is to flash for 30 seconds at key ON when one
of the following occurs:
•
Maintenance is required (if the Maintenance Monitor
feature is enabled)
•
Water in fuel is detected.
If the warning light flashes for 30 seconds at Ignition Switch
ON and water is drained from the primary water-separating
fuel filter, the secondary fuel filter must be replaced.
Fault codes can be accessed using the electronic service tool
or by fault code flash out.
To check for active engine electronic fuel system and engine
protection system fault codes, turn the Ignition Switch OFF
and move the diagnostic switch to the ON position.
Turn the vehicle Ignition Switch to the ON position.
If no active fault codes are recorded, both lights will come on
and stay on.
If active fault codes are recorded, both lights will come on
momentarily, then begin to flash the code numbers of the
recorded fault codes.
The fault code flashes in the following sequence:
•
A WARNING (amber) light flashes.
•
Following a short one or two second pause, the number
of the recorded fault code flashes in the STOP (red) lamp.
•
There is a one or two second pause between each num-
ber.
•
After the number finishes flashing in red, an amber light
appears again.
The lights flash each fault code out three times before ad-
vancing to the next code. To skip to the next fault code, move
the Increment/Decrement switch, if equipped, momentarily
to the increment (+) position. You can go back to the pre-
vious fault code by momentarily moving the Increment/
Decrement switch, if equipped, to the decrement (-) position.
If only one active fault code is recorded, the same fault code
will continuously be displayed when either (+) or (-) switch is
depressed.
The diagnostic switch must remain in the OFF position
(shorting plug removed) while the engine is being operated
