Travel Speed Selector Switch
WARNING
When loading or unloading the machine on a trailer, always travel at low speed (set to Lo). Never operate the travel speed
selector switch when traveling.
If the Hi-Lo switch is operated when the machine is traveling, the machine may deviate to one side even when it is traveling in
a straight line. Always stop the machine before changing the travel speed.
The area at the rear of the machine is a blind spot. Always use the rear view camera to check the area at the rear of the machine
before traveling in reverse.
This switch (3) is used to set the travel speed to 2 stages.
Lo lights up : Low-speed travel
Hi lights up : Hi-speed travel
When the engine is started, the speed is automatically set to Lo.
Each time that the switch is pressed, the display changes Lo J
Hi J Lo in turn.
When traveling in high speed (Hi), if travel power is needed, such
as when traveling on soft ground or on slopes, the speed
automatically switches to low speed (Lo), so there is no need to
operate the switch. The monitor display stays at Hi.
REMARK
Each time travel speed selector switch (3) is switched, the mode is
displayed on the monitor display, and after two seconds, the
screen returns to the standard screen.
