The AVSpare Monitoring System consists of a monitoring panel, action light (3), and individual alert indicators (2) for the different machine systems. In addition, the system has gauge panel (1) .
The monitoring system alerts the operator of a problem or of an impending problem. The panel is designed to alert the operator of faulty machine systems.
Functional Test
Check the operation of the monitoring system. Observe the self testing feature when you start the engine.
The self testing feature verifies that the modules of the monitoring system are properly operating.
The internal circuits are automatically checked. The outputs (gauge display, action light, and the action alarm) are automatically checked.

The operator must observe the outputs in order to determine if the modules are operating properly. This self testing feature is three seconds long.
During the self test, all alert indicators flash.
The pointers in the gauges point upward. Then, the pointers point to the left. Then, the pointers point to the right. Then, the pointers point to the final position.
- The action light stays illuminated.
- The action alarm sounds once.
The monitoring panel is then in the normal operating mode. If a switch is grounded, the monitoring system will display the modes.
Warning Categories
The monitoring system provides three warning categories. The first category requires only operator awareness. The second category requires the operator to respond to the warning. The third category requires immediate shutdown of the machine systems.
Warning Category 1
In category 1, only the alert indicator will flash. This category alerts the operator that the machine system needs attention.

| Alternator (1) - This indicator indicates that the alternator is malfunctioning. If this indicator illuminates, stop the machine at a convenient place. Investigate the cause. The cause may be a loose belt or a broken belt. |
Do not operate the machine until the cause has been corrected.
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 the alert indicator continues to flash, do not operate the machine. If the action light continues to flash, do not operate the machine.

| Hydraulic Oil Temperature (2) - This indicator indicates excessive hydraulic oil temperature. If this indicator flashes, reduce the load on the machine. If the indicator remains on, stop the machine at a convenient place. Investigate the cause. |
Do not operate the machine if the indicator remains on, and the fault light flashes.
| Coolant Temperature (3) - This indicator indicates excessive coolant temperature. If this indicator illuminates, stop the machine at a convenient place. Investigate the cause. |
Do not operate the machine if the indicator remains on, and the fault light flashes.
| Transmission Oil Temperature (4) - This indicator indicates excessive transmission oil temperature. If this indicator illuminates, reduce the load on the machine. Stop the machine at a convenient place. Investigate the cause. |
| Transmission Oil Filter (5) - This indicator indicates that the transmission oil filter should be changed. Change the transmission oil filter. See Operation and Maintenance Manual, "Transmission Oil Filter - Replace". |
Warning Category 3
In this category, the alert indicator lights and the action light flashes. Also, the action alarm will sound. This category requires immediate shutdown of the operation in order to prevent severe damage to the system and/or to the machine.

| Engine Oil Pressure (6) - This indicator indicates low oil pressure. If this indicator flashes, stop the machine immediately. Stop the engine and investigate the cause. |
Do not operate the machine if the indicator remains on, and the fault light flashes.
