Auto-Idle - Hitachi ZAXIS 450LC-3 Operator's Manual

AUTO-IDLE

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) 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.

WARNING: Prevent the machine from unexpected
movement. Be sure to turn off auto-idle selector (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 selector (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 selector (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 activated, allowing auto-idle indicator (1) to flash
for 5 seconds and stay ON later.
