•Remove foreign objects from the stock. Make sure that any stock you process with the jointer is clean and free of any dirt, nails, staples, tiny rocks or any other foreign objects that may damage the jointer blades.
•Only process natural wood fiber through your jointer. Never joint MDF, particle board, plywood, laminates or other synthetically made materials.
•Make sure all stock is sufficiently dried before jointing. Wood with a moisture con- tent over 20% will cause unnecessary wear on the knives and poor cutting results.
•Make sure your workpiece exceeds the minimum dimension requirements (Figures 20 & 21) before edge jointing or surface planing, or it may break or kick back during the operation!
