Auto-Idle

Auto-Idle Function
With auto-idle selector (3) turned to the A/I ON position,
approximately 4 seconds after all control levers are returned
to neutral, the engine speed decreases to the auto-idle
setting to save fuel consumption.
The engine speed will immediately increase to the speed
set by engine control dial (2) when any control lever is
operated.
IMPORTANT:
 Always check if auto-idle indicator (1) is turned ON or
OFF before starting operation. If the indicator is ON,
the auto-idle function will be activated.
 Always be aware of engine control dial (2) setting
when auto-idle selector (3) is turned to the A/I ON
position. If the engine speed is set high with engine
control dial (2), and if the operator is not aware of
the high engine speed setting, the engine speed
will unexpectedly increase when any control lever is
operated, causing unexpected machine movement,
thus possibly resulting in serious personal injury.
d
WARNING: Prevent the machine from unexpected
movement. Be sure to turn auto-idle selector (3) to the
A/I OFF position when unexpected machine movement
is undesirable, especially when loading/unloading the
machine for transportation.
f
NOTE: Auto-idle control may not work completely until the
end of the warm-up.
