L - Level - Your brush level should be checked before sweeping operation begins, this will extend
the brush life of the unused bristles by 50%

So test your down pressure before starting a job. The correct down pressure should clear a 4-6 inch path.
S - Speed - Maintain a low ground speed while sweeping at a higher brush speed obtaining a sweeping
effect verses a bull-dozing effect, which in turn damages the life of your brush bristles.
