When the bucket has been operated to the DUMP position, if the
control lever is pulled to the TILT position, it will be held at that
position and the bucket will continue to move.
When the bucket reaches the position set by the bucket positioner,
the control lever is automatically returned to the HOLD position and
the bucket movement stops.
If the lift arm is lowered in this condition, the bucket will contact
the ground horizontally. If the bucket is not horizontal, adjust again.
