Auto speed control (OPT)
This function automatically limits the maximum
speed, the acceleration and the deceleration by detect-
ing the forks height (Low/High) and the loaded weight,
reducing the possibility of falling of loads.
Caution Caution Caution
• Do not blindly rely on Auto Speed Control
• Maximum speed and the acceleration (decelera-
tion) are suppressed corresponding to the
weight of loads at high position. But it doesn’t
necessarily mean that it will not turn over. So
safe driving is always necessary.
• When loads are lifted to high position, never
step on the accelerator pedal suddenly, or never
shift the vehicle from the neutral to driving con-
dition with keeping the accelerator pedal
stepped on.
• The fluctuations of the vehicle speed and accel-
eration can be caused temporarily even under
the controlled condition, by changes of road
conditions.
Specifications of control
Lift-height and load-sensing vehicle speed control
This feature improves the stability while driving with
heavy loads at the high lift position, by limiting the
maximum speed, depending on the load at the high lift
position.
Height position and the weight of loads are detected by
the height switch and the load sensor, which are used
in SAS control, and the maximum speed is controlled
in range from unlimited speed to approximately 8 km/h
depending on the weight of loads when the height
switch detects high side.
Note:
• When the maximum speed limit is disabled, the
sudden acceleration is suppressed until the acceler-
ator pedal is stepped off, or until the speed
becomes stable.
• In case that the vehicle speed has already exceeded
the maximum speed, it is gradually decreased and
limited to the maximum speed.
• If the maximum speed limiter and/or low speed set-
ting has been set, the lowest limit speed is adopted
including the limit speed of this feature.
Lift-height and load-sensing acceleration and decel-
eration control
This feature can improve the stability while driving
with the heavy load at the high lift position, by limiting
the acceleration (deceleration) depending on the load.
For example, it can reduce the possibility of falling of
loads, in operational errors that the accelerator pedal
has been suddenly stepped on (off) or that the direction
switch has been shifted while the accelerator pedal is
fully stepped on.
Note:
• Because the deceleration limitation is released at
the speed of less than 3km/h when the forklift
approaches to the racks, it can be operated in ordi-
nary feeling of the accelerator off regeneration
brake.
• The deceleration limitation is also released when
the switchback operation has been done, because it
can be taken as the braking operation.
• Brake pedal operations always precede the deceler-
ation limitation of Auto Speed Control.
Auto speed control indicator
The Auto Speed Control Indicator is displayed on the
multi-function display while it is activating (1).
The indicator is also displayed for a while after the key
switch is turned on (2) to inform that this feature is in
available configuration.
If only acceleration/deceleration control is available
(with speed control disabled by dealer), the indicator is
shown with inverted colors.
