PANEL AS-SOUND SUPPRESSION 3534493 - Caterpillar

Engine Air Intake (2) - This indicator shows that the filter for the engine air intake should be changed. If this indicator flashes, change the filter for the engine air intake. The electronic controls may derate the engine horsepower if the filter is not changed. For detailed information on the filter for the engine air intake, see the topic "Engine Air Filter Primary Element".
Check Engine (3) - This indicator indicates that diagnostic information is present in the engine control system. This does not indicate a problem with the engine operation. If this indicator lights, the operator should check the engine at the earliest possible time.
Engine Overspeed (4) - The tachometer enters the yellow zone when engine speed exceeds 2500 rpm. The yellow zone is a visual warning. The yellow zone indicates that the machine is approaching the maximum recommended engine speed limit. The operator should adjust operating techniques in order to minimize these events. Warning Category 2
In this category, the alert indicator flashes and the action light flashes. The warning category requires you to change the machine operation. Changing the machine operation will reduce the excessive temperature in one of the systems or in more than one of the systems. Also, changing the machine operation will reduce the excessive engine speed.If warnings continue to flash after changing the machine operation, do not operate the machine.

Engine Coolant Temperature (5) - The needle in the red zone of the gauge indicates excessive coolant temperature. Change the operation of the machine in order to reduce coolant temperature. If the coolant temperature is not reduced, pull the machine to a convenient stop. Investigate the cause.
Transmission Oil Temperature (6) - The needle in the red zone of the gauge indicates excessive transmission oil temperature. Change the operation of the machine in order to reduce transmission oil temperature. If the transmission oil temperature is not reduced, pull the machine to a convenient stop. Investigate the cause.
Engine Overspeed (7) - The tachometer provides the operator with a visual warning when the engine is overspeeding. The red zone informs the operator that the engine is exceeding the maximum recommended speed limits. The red action light and the auxiliary light will turn on at 2700 rpm. The red action light and the auxiliary light will turn off at 2600 rpm. The pointer on the tachometer will remain at the maximum speed reached for several seconds. The pointer will then return to the position for actual monitoring. The maximum speed will automatically appear on the digital display window until the operator acknowledges the warning by pressing the diagnostic scroll switch. The hour meter will then reappear. These features are designed to alert the operator that machine operation needs to be adjusted in order to reduce the risk of engine damage.
Hydraulic Oil Temperature (8) - The needle in the red zone of the gauge indicates excessive hydraulic oil temperature. Change the operation of the machine in order to
