4.3 Controls

The R160T / R190T machines have two hydraulic pilot joystick controls. The joy-
sticks are used to control machine speed and direction as well as lift arm and
bucket functions.

The lift arm joystick is used to control the lift arms, bucket, and to engage the
float function. The illustration above shows the relationship between joystick
movement and resulting lift arm action.
Note: To activate the float function, move the joystick fully forward in a quick
motion. The joystick will then be held in detent by the magnet attached to the
joystick base. Pull back quickly to disengage the float function.
4.3.2 Drive Control
The drive joystick controls the direction and speed of the machine. The illustration
above shows the relationship between joystick movement and resulting machine
