RT765E-2 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
LCD Display
The LCD Display(12) (Figure 3-6) is located in the steering
column gauge display. The display shows the transmission
gear being used, fault codes, and master software version.
If an active engine fault code is present, the display will show
the code when the Ignition Switch is in the RUN position and
the engine is off. The display will show the master software
version when the Ignition Switch is in the ACC position.

Engine Stop
The Engine Stop Indicator (13) (Figure 3-6) is located in the
steering column gauge display. It illuminates red when a
signal is sent from the engine ECM. In addition, a warning
buzzer will also sound.
If this indicator light illuminates, note the fault code, shut the
engine off and refer to the Engine Operator Manual.
Engine Warning
The Engine Warning Indicator (14) (Figure 3-6) is located in
the steering column gauge display. It illuminates amber when
a signal is sent from the engine ECM.
If this indicator light illuminates, note the fault code and see
Engine Operator Manual.
The Engine Warning Indicator may also illuminate with the
Diesel Particulate Filter Indicator or Diesel Exhaust Fluid
Indicator.
Diesel Particulate Filter (Tier 4 Engines Only)
The Diesel Particulate Filter (DPF) Indicator (15) (Figure 3-6)
is located in the steering column gauge display. This
indicator illuminates amber when the diesel particulate filter
is getting filled with soot and needs to be cleaned out.
When the DPF indicator illuminates or flashes, start
regeneration process.
The indicator will be lit continuously during the early stages
of clogging. If the system continues to clog, the lamp will
begin to flash and slight engine derate will occur.
If even more clogging occurs, the engine warning light (14)
will illuminate in addition to the DPF indicator (15) and
severe engine derate will occur.
The regeneration process can take place in three different
modes:
Passive: the exhaust is hot enough during normal working
operation to burn off any hydrocarbon (soot) accumulation
Active: Active self-regeneration occurs when there is not
sufficient heat in the exhaust to convert all the hydrocarbon
being collected in the DPF. Exhaust temperatures are raised
by injecting a small amount of fuel. The resulting chemical
reaction raises exhaust gas temperatures high enough to
oxidize the hydrocarbon from the filter. This is all done
without any operator intervention.
Manual: Manual or stationary, regeneration is the same as
active regeneration but takes place while the equipment is
not being operated. It offers the equipment operator the
option, if needed, of performing regeneration outside the
normal duty cycle.

WARNING
Extreme Heat Hazard!
During the regeneration process the exhaust becomes
very hot. Do not park the vehicle near objects that are
flammable.
Use caution near the exhaust tailpipe as it will also
become very hot.
