AUTO-IDLE CONTROL (Except ZX27U
Auto-Idle Function
During operation, approximately 4 seconds after all con-
trol levers have been returned to neutral, this system
reduces the engine speed to the auto-idle setting until
any control lever is operated again to improve fuel con-
sumption. The engine speed immediately increases to
the speed set by the engine control dial when any control
lever is operated.
CAUTION:
•
Always check if auto-idle indicator (2) is turned
ON or OFF before starting operation. When the
indicator is ON, the auto-idle function will op-
erate.
•
When any control lever is operated from the
neutral position with auto-idle switch (1) turned
ON, the engine speed will increase to the speed
set by the engine control dial. Therefore, al-
ways be aware of engine control dial setting
before starting operation to prevent the engine
speed from increasing unexpectedly.
•
When unexpected machine movement could be
dangerous, such as when loading/unloading
the machine for transportation, or when the
machine is engaging in lifting work, turn
auto-idle switch (1) OFF to ensure safe opera-
tion.
•
Use the auto-idle function only after warm-up
operation is complete. Failure to do so may not
reduce the engine speed.
Note that the auto-idle function can be turned ON or OFF
only when the key switch is in the ON position. Check if
the auto-idle function is turned ON or OFF with auto-idle
indicator (2).
Auto-Idle Switch
ON: Auto-idle indicator (2) ON.
OFF: Auto-idle indicator (2) OFF.
After the key switch is turned OFF when the auto-idle
function is activated [with auto-idle indicator (2) ON],
when the engine is restarted, the auto-idle indicator
flashes for 10 seconds and the auto-idle function be-
comes activated later.
