For levers 2, 3 and 4, the engine speed changes as follows
because of the auto-deceleration mechanism.
When the travel lever and work equipment control levers are at
neutral, even if the fuel control dial is above the mid-range
position, the engine speed will drop to a mid-range speed.
If any of the levers 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).
