The EBG-20/C PIVOT Surface Preparation Machine features a smooth 3450 rpm motor, 50-foot, 14 gauge power cord with lighted hospital grade plug, removable weights and Dust Containment Kit. The 6Ó x 2Ó non-marking ball bearing wheels are coupled with a 3/4Ó axle for greater mobility. The new Square Scrub Pivot includes a pivoting head for balanced contact & easier control. The pivoting head releases the control handle from the bottom of the base, allowing the machine to pivot freely front to back. This pivoting motion follows uneven floors more efficiently.
