a. N (Neutral) is normal transmission position when machine is not in use. Use N to start engine, when idling
engine, and for parking. Always lock transmission in neutral when machine is left unattended in N, parked,
or stopped.

reverse. Backup alarm will also sound when in reverse, unless the military light switch is in B.O. (blackout)
mode.

(1) Positions 1 and 2 are suitable for low speeds. They must be manually selected. During load, haul, and
dump cycles, manual shifting is not recommended.
