The slow (1800 RPM) constant speed of the drum will not gouge floors.
The tilt action for the SL-8 allows for more controlled and even sanding when compare to other machines available to the rental trade. When you sand forward and backward with the SL-8, you can be assured of straight sanding because it runs on the drum and wheels. The weight of the machine is specifically designed and evenly distributed for the best results.
We have manufactured the SL-8 with a 1 hp completely sealed, repulsion-induction Baldor motor. It will run the drum at 1800 RPM constantly on 14 amps (standard household current). Because of this design, unique to the Silver-Line motor, the drum will not slow down or speed up as it sands, resulting in a level, smooth finish without waves.
