Transmission Oil Filter (8) - This indicator indicates that the transmission oil filter should be changed. If this alert indicator flashes, change the transmission oil filter. Refer to Operation and Maintenance Manual, "Transmission Filter".
Engine Overspeed (9) - The tachometer will function in the "sticky-tach" mode. The operator monitor panel will also function in the "sticky-tach" mode. The tachometer and the operator monitor panel will function during the "level 2" or the "level 3" engine overspeed. The analog tachometer will display the high engine speed that was attained. The actual engine speed will not show on the display. The analog tachometer will continue to display the high engine speed that is attained for 30 seconds. This continues until the "engine overspeed" indicator is turned off. The overspeed can occur in any operating mode. The digital display will show the engine high rpm that was attained when the overspeed occurs. The engine high rpm will be the same reading as the tachometer reading. The operator monitor panel will display this reading until the operator has activated the reset switch button. Once the operator has activated the switch, the display returns to the display mode. During a 30 second "sticky-tach" period, the following events may occur: Engine overspeed can occur. Then, the engine overspeed goes away. Engine overspeed then reoccurs. A display of the previous high speed will remain on the tachometer and on digital display until the latest engine overspeed exceeds that level. The "sticky-tach" feature will function during the duration of the latest event, plus 30 seconds after the most recent event ends.
Hydraulic Oil Temperature (10) - The needle in the red zone of the gauge indicates excessive hydraulic 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.
