If the work equipment control levers are returned to NEUTRAL position when the machine is stopped, even if
the fuel control dial is set to High idle (MAX) position, the auto-deceleration mechanism works to reduce the en-
gine speed to the low speed.
REMARK
This machine is equipped with an accumulator in the control circuit. Even if the engine is stopped, if the starting
switch key is turned to ON position within 15 seconds after stopping the engine, and the lock lever is set to
FREE position, it is possible to use the lever operation to lower the work equipment to the ground.
This procedure can also be used for releasing the remaining pressure in the hydraulic cylinder circuits or for
lowering the boom after loading the machine onto a trailer.
