MOM Display Screen Air Cleaner Vacuum Gauges MOM display (10, Figure 32-1) is an electronic dis- play that provides the operator or service technician with important messages concerning selected truck functions. Air cleaner vacuum gauges (14, Figure 32-1) provide a continuous reading of maximum air cleaner restric- tion reached during operation. The air cleaner(s) should be serviced when the gauge(s) reaches 6.2 kPa (25 in. of H 2 O) vacuum. Refer to Electronic Displays And Messages later in this section, for a detailed description of the mes- sages provided and the functions monitored by this display. NOTE:
After service, push the reset pin on the face of the gauge to allow the gauge to return to zero. Payload Meter MOM Dimmer Switch Payload meter (15, Figure 32-1) is used to provide management with operational data such as tonnage hauled and cycle times.
