The Electronic Monitoring System (EMS) is located on the front dash in the operator compartment. The EMS consists of an action alarm, action light (1), and monitoring panel (2). The monitoring panel includes an individual alert indicator for each machine system that is listed on the monitoring panel.
The EMS is designed to alert the operator to an immediate problem with any of the machine systems that are monitored. The EMS is also designed to alert the operator to an impending problem with any of the machine systems that are monitored. The action light and the individual alert indicators will light when a problem occurs.
EMS Functional Test
To ensure the proper operation of the EMS, check the system daily.
The battery disconnect switch must be in the ON position in order to supply electrical power to the machine.
