REMARK
The engine speed for all control levers (travel, work equipment, attachment) is changed as follows by the auto-
deceleration mechanism.
When the travel lever and work equipment control levers are at the neutral position, even if the fuel control dial is
above midrange speed, the engine speed will go down to a midrange speed. If one of these levers is operated, the
engine speed will rise to the speed set by the fuel control dial.
If all the control levers are at the neutral position, the engine speed goes down approx. 100 rpm, then after approx.
4 seconds, the engine speed goes down to the deceleration speed (approx. 1400 rpm).
