AUTO-IDLE

With auto-idle switch (3) turned to the A/I ON position, ap-
proximately 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 switch (3) 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 en-
gine speed setting, the engine speed will
unexpectedly increase when any control
lever is operated, causing unexpected ma-
chine movement, thus possibly resulting
in serious personal injury.
WARNING: Prevent the machine from unexpected
movement. Be sure to turn off auto-idle switch (3)
when unexpected machine movement is undesirable,
especially when loading/unloading the machine for
transportation.
Note that auto-idle function can be turned on or off only when
the key switch is in ON position. Always check if the auto-idle
function is turned on or off with auto-idle indicator (1).
Auto-Idle Function ON :
Auto-Idle Function OFF :
• When auto-idle switch (3) is turned OFF with auto-idle
indicator (1) ON, indicator (1) will go OFF and the auto-
idle system is deactivated.
• Even if the engine is stopped by turning the key switch
with auto-idle switch (3) in the A/I ON position [indicator
(1) ON], the auto-idle system is not deactivated. When the
engine is restarted, the auto-idle system remains activat-
ed, allowing auto-idle indicator (1) to flash for 5 seconds
and stay ON later.
