PLACING VEHICLE IN MOTION - CONTINUED

NOTE

If available, assistant will adjust mirrors with driver seated

in cab.

3. Adjust rear view mirrors and driver seat as necessary. Put seatbelt(s) on and

adjust tension (WP 0007).

NOTE

Ensure scheduled PMCS are performed prior to operating

tractor.

4. Start engine (WP 0008 or WP 0009).

5. Check engine oil pressure gauge (Figure 1, Item 3) for at least 10 psi (69 kPa) at

idle. Cold engine will read higher.

6. Check engine water temperature gauge (Figure 1, Item 7) for approximately

165–195° F (74–91° C) for M915 through M920 or 160–180° F (71–82° C) for

M915A1 if pulling load.

7. Check air pressure gauges (Figure 1, Items 4 and 6) for

105–140 psi (724–965 kPa). Air pressures below 60 psi (414 kPa) will result in

brakes not releasing. LOW AIR PRESSURE warning lamp (Figure 1, Item 5) and

buzzer should go off when both front and rear air system pressures reach

approximately 64–76 psi (441–524 kPa).

8. Voltmeter (Figure 1, Item 2) should indicate 12–15 V (green shaded area).

9. Fuel gauge (Figure 1, Item 1) should indicate there is sufficient fuel for intended

mission.

10. If operating in conditions requiring use of service or blackout lamps, operate

headlamp switch (Figure 2, Item 1) or blackout operation switch

(Figure 2, Item 2) as appropriate (WP 0005).
