6.4.2 Structure and function
The joystick steering system is a system used to steer wheel
loaders with a lever instead of a steering wheel.
The joystick enables steering with small, light movements, and
helps to reduce operator fatigue.
When joystick ON/OFF switch (1) is turned ON, it becomes pos-
sible to operate the steering with the joystick.
When the joystick steering is in use, the joystick pilot lamp on
the machine monitor lights up.
On machines equipped with the joystick steering system, it is
possible to use joystick ON/OFF switch (1) to select the steering
and transmission operation method as shown in the table below.
In addition, on machines equipped with joystick steering, the
transmission auto shift function is also included.
The differences between operation using the joystick and opera-
tion using the steering wheel are as follows.
*: Does not shift up above speed range of gearshift lever.
