This optional system is designed to make the basic installation and set up of the GARED® PRO S effortless. It eliminates the need to adjust the leveling pads by automatically lifting the front wheels off the ground when the boom is raised to the play position and lower them when the boom is lowered to the folded or stored position. As the portable is raised, a cam operated mechanism raises the front wheels off the floor causing the boom to lock in the play position and the base to rest evenly on the supporting frame. Conversely when the wheels are in the down position, the portable can be moved around.
