Check the locking function of the joystick regularly. Carry out the function
test only when the vehicle is at a standstill.
When the locking function is switched on, the loader unit must not move
when the joystick is operated. If the loader unit does move, there is a
technical defect which must be repaired by an authorized service center.
Do not put the vehicle back into operation
