For levers b, c and d, the engine speed changes as follows be-
cause of the auto-deceleration mechanism.
• When the travel lever and work equipment control levers are at

the engine speed will drop to a mid-range speed. If any of the le-
vers are operated, the engine speed will rise to the speed set by
the fuel control dial.
• If all control levers are set to neutral, the engine speed will drop by
approx. 100 rpm, and after approx. 4 seconds, the engine speed
will drop to the deceleration speed (approx. 1400 rpm).
