Display panel with longitudinal stability indicator
Engine Coolant Temperature (17) - This
gauge indicates the temperature of the engine
coolant. The green zone indicates that the
engine coolant temperature is normal. The red zone
indicates that the engine coolant is overheating. If the
gauge indicates overheating, stop the engine.
Investigate the cause. Check the coolant level. Check
that the fan drive belt is not broken or loose. Check
that the radiator fins are clean.
Tachometer (18) - This gauge indicates the
speed of the engine in revolutions per minute, if
equipped. Refer to Illustration
Torque Converter Oil Temperature (19) -
This gauge indicates the temperature of the
transmission and hydraulic system oil after the
oil has passed through the torque converter. The green
zone indicates that the temperature of the transmission
and hydraulic system oil is normal. The red zone
indicates that the torque converter temperature is
overheating.
Hydraulic Oil Temperature (20) - This
indicates the temperature of the
transmission and hydraulic system oil in the
sump. The green zone indicates that the temperature
of the transmission and hydraulic system oil
temperature is normal. The red zone indicates that the
transmission and hydraulic system oil is overheating.
Speedometer (21) - This digital display indicates the
current speed of the machine.
Service Hour Meter (22) - This digital display
indicates the total operating hours of the engine. The
service hour meter should be used to determine the
service hour maintenance intervals.
Fuel Level (23) - This gauge indicates the
amount of fuel that is left in the fuel tank. When
the needle on the fuel gauge reaches the red
area the fuel tank should be filled.
Longitudinal Stability Indicator (24) - This gauge
indicates the longitudinal stability of the machine, if
equipped. Refer to Illustration 139. Refer to
"Longitudinal Stability Indicator" for more information.
Longitudinal Stability Indicator
Operating the machine beyond its stability limit could
result in a tip over or failure of the work tool. Check the
proposed lift with the load chart. Do not attempt the lift if
the longitudinal stability limit of the machine will be
exceeded. Tip over or failure of the work tool could
cause personnel injury or death.
Your machine may be equipped with a longitudinal
stability indicator. The longitudinal stability indicator
provides audible signals and visual signals in order to
indicate the limit of the forward stability of the machine,
if equipped. The audible signal is shared with other
system failures. Refer to Operation and Maintenance
Manual for usages of the audible signal. The
longitudinal stability indicator is powered by the
machine electrical system which is activated when the
engine start switch key is turned to the ON position.
Ensure that a Caterpillar work tool is attached to the
machine and use the correct load chart in order to
verify that the intended lift operation is within the
capability of the machine. Refer to Operation and
Maintenance Manual, "Lifting Capacities" for the
location of the load charts.
The forward stability of the machine will depend on the
following factors:
• Weight of the attachment
• Weight of the load
• Angle of the boom
• Length of the boom
• The position of the stabilizers (if equipped)
Illustration 140 g01014337
The longitudinal stability indicator has a variable gauge
(24) that indicates the longitudinal stability of the
machine. The indicator shows the status of the
attempted lift operation in comparison to the limit of the
