Using your Slim Slab Table Tool Shelf is a breeze. First, find the rails of your S³ | Slim Slab Table HD. Attach the tool shelf to these rails. Then, place your grinder and core bits in the unique cut - outs provided. Stick your polishing pads to the velcro backing. When using the shelf, make sure the attachments are secure to avoid any tools falling. For maintenance, wipe it down with a clean, dry cloth regularly. If it gets dirty, you can use a mild soap and water solution. Avoid using harsh chemicals as they may damage the stainless steel and zinc - plated steel parts. Also, check the velcro periodically to ensure it's still sticky enough to hold your polishing pads.
