Loader Control Joystick Operation – The right-hand
joystick controls the loader arm and the at-tachment tilt
cylinder. It allows the operator to raise, lower and pivot
the attachment. The joystick operates on hydraulic
charge pressure.
The loader control also has a float position, which is
activated by moving the joystick completely forward
until it is held in detent. The joystick is held in the for-
ward float position by an electromagnet.
The tools required for loader/drive control joystick
removal and installation are listed in Table 9 1. Use
manufacturer recommended tools whenever possible.
