RT9130E-2 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
Right Turn Signal Indicator
The Right Turn Signal Indicator (16, Figure 3-7) is located in
the steering column gauge display. It is a green arrow light
that flashes when the turn signal lever is pushed up or the
Hazard Light Switch is positioned to On.
Inhibit Cleaning
The Inhibit Cleaning Indicator (17, Figure 3-7) is located in
the steering column gauge display. When the Cleaning
Switch (9, Figure 3-4) is in the inhibit cleaning position, this
amber indicator is illuminated and both manual and active
cleaning will be inhibited.
Diesel Exhaust Fluid (Tier 4F Engines Only)
The Diesel Exhaust Fluid (DEF) Level Indicator (18,
Figure 3-7) is located in the steering column gauge display.
The indicator has four different stages which will be triggered
by the fluid level sensor in the DEF tank.
Low Tank: First warning to the operator is that the reducing
agent in the tank is low. The Low DEF Indicator (18) will be lit
continuously.
Derate: The Low DEF Indicator (18) will start to flash as a
warning to the operator that a derate will be activated if the
reducing agent in the DEF tank is not refilled.
Low Level Inducement: The Low DEF Indicator (18) will
flash and the Engine Warning Indicator (14) will be lit
continuously. Derate will be activated at this stage.
Severe Inducement: Once the DEF tank is empty, the crane
operation will be restricted. The Low DEF Indicator (18) will
flash and the Stop Engine Indicator (13) will be solid red.
High Exhaust System Temperature
The High Exhaust System Temperature (HEST) Indicator
(19, Figure 3-7) is located in the steering column gauge
display.
During cleaning it is possible for the engine exhaust to reach
temperatures exceeding 1200°F. The HEST indicator will
illuminate red to warn the operator of when temperatures
reach 640°C (1184°F) and will stay on until the temperature
falls below 625°C (1157°F).
A warning light near the tailpipe will flash during cleaning
when high exhaust temperatures exist.
For more information on the cleaning process, refer to
Exhaust System Cleaning (Tier 4 Engines Only), page 3-14
Engine Wait to Start
The Engine Wait To Start Indicator (20, Figure 3-7) is located
in the steering column gauge display. It illuminates amber for
a period of time when the ignition switch is in the ON
position. The engine should not be cranked until the Wait to
Start light turns OFF. This light is controlled by the engine
ECM.
Four-Wheel Drive Engaged
The Four-Wheel Drive Indicator (21, Figure 3-7) is located in
the steering column gauge display. It illuminates amber when
the Drive Axle Selector Switch (5, Figure 3-2) is in the four-
wheel low position. When in four-wheel drive only first and
second gears are enabled. This lamp will blink when the two-
wheel drive/four-wheel drive is selected without the brake
pedal depressed and the transmission in neutral.
Interaxle Locked
The Interaxle Locked Indicator (22, Figure 3-7) is located in
the steering column gauge display. This indicator illuminates
when the Differential Lock Switch (10, Figure 3-9) is pressed
to the Lock position, when in the Lock position there is no
differential action between the wheels.
Rear Wheels Not Centered Indicator
The Rear Wheels Not Centered Indicator (23, Figure 3-7) is
located in the steering column gauge display. The indicator is
an amber light that will illuminate any time the rear wheels
are not centered.
Engine Coolant Temperature Gauge
The Engine Coolant Temperature (water temp) Gauge (25,
Figure 3-7) is located in the steering column gauge display.
The gauge indicates the engine coolant temperature on a
dual scale calibrated from 38 to 138°C and 100 to 280°F. The
gauge receives a signal from the engine ECM and a
temperature sending unit in the engine cooling system.
Fuel Gauge
The Fuel Gauge (26, Figure 3-7) is located in the steering
column gauge display. The gauge indicates the quantity of
fuel in the fuel tank and has a scale calibrated from 0 (zero)
to 4/4 (full). The fuel gauge receives a signal from a sending
unit in the fuel tank.
Low Fuel Level
The Low Fuel Level Indicator (27, Figure 3-7) illuminates
when the fuel level in the tank is nearing empty (15%) and
the crane is in danger of running out of fuel. When this
CAUTION
Engine Damage Hazard!
Ultra low sulfur diesel fuel required in Tier 4 engines.
If “Ultra Low Sulfur” fuel is not used in engines that require
it, the Cummins warranty will be void and the engine
performance will quickly deteriorate and may stop
running.
