Using your Malish Dust Skirt is easy. First, pick the right size (17” or 20”) for your floor machine. Then, use the VELCRO® quick - connect system to attach the dust skirt to the housing of your single - disc floor machine. When you start your sanding, grinding, or buffing project, the dust skirt will start doing its job, containing the dust. Make sure the skirt shroud is in contact with the floor for best results. For maintenance, regularly check the black reinforced nylon brush. If it gets too dirty or worn out, you may need to replace it. Also, clean the adjustable skirting to keep it flexible. Store the dust skirt in a dry place when not in use to prevent damage.
