At that time, the operator is provided a chance to inspect and ensure that there are no obstructions in the area of the vehicle and lifts. After confirmation that the vehicle and lift area is clear of obstructions, the operator simply needs to retract the mechanical safety locks again and compete the lowering cycle to bring the lift completely to the floor.
