EMS INSTRUMENT CLUSTER CONTINUED
Brake Pad Wear
0004
The machine is fitted with a disc brake system operating disc pads on all four wheels. Embedded into each pair of pads are
contacts. The contacts are connected electronically to the EMS. When the pads wear to a pre-set minimum level, the contacts
are exposed. When the machine ignition is ON and the foot brakes are applied, the contacts in the pads are shorted together by
the brake discs and complete the electrical circuit. When the EMS senses this condition in one or more pad contacts, the EMS
illuminates the warning light (Figure 41, Item 17), sounds the internal buzzer, and displays the message "BRAKE PADS" on
the LCD. The message will be displayed for a period of five seconds, after which it will extinguish until the circuit is activated
again by applying the brakes. The buzzers can be canceled by pressing the OK button (Figure 41, Item 5). As soon as the brake
pad wear light and message are displayed, contact Field Maintenance.

Low Brake Fluid Level
0004
The machine s braking system fluid reservoirs are fitted with electrical float switches. When the fluid level in one or more of
the reservoirs falls below a pre-determined level, the EMS unit is activated. The EMS will illuminate the warning light (Figure
41, Item 17) on the EMS panel, sound the internal and external buzzers, and display the message "BRAKE FLUID LO" on the
LCD. The buzzers can be extinguished by pressing the OK button (Figure 41, Item 5).
