STRUCTURE AND FUNCTION OF JOYSTICK STEERING

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
possible to operate the steering with the joystick.
Before turning this switch (1) ON, adjust the position of the joystick
console and check that there is no play in the console.
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.
The differences between operation using the joystick and
operation using the steering wheel are as follows.
