EFFICIENT AND ECONOMICAL DRIVING TECHNIQUES (M915A1) - CONTINUED

NOTE

Running in a low gear at a high rpm when restricted to

25–30 mph wastes fuel and creates a higher noise level than

necessary.

3. When driving conditions do not permit operating in economy range, it may be

necessary to run engine at higher engine speeds (full throttle) or manually shift to

a lower gear. When operating in hilly terrain, high winds, or at maximum GCWR,

additional power to meet these conditions may require operating in gear range 1-4

(Figure 13, Item 2) or lower.
