MAINTENANCE CHANGING BLADES See Figures 14 - 16. The planer blades are reversible. When one edge becomes dull, the blade can be reversed so that the other side can be used. Always replace or reverse blades in pairs. Do not attempt to sharpen blades. If the blades in the planer show signs of becoming dull, chipped, or damaged in any way, replace them. When changing blades, use the recommended replacement blades only (Part No. 671798001). WARNING: The blades are sharp. Use extreme caution when replacing blades. Failure to heed this warning can result in serious personal injury.  Remove the battery pack from the tool.  Secure the planer in an upside-down position.  Loosen the two screws securing the blade and blade clamp on the blade holder using the blade wrench provided. Loosen the screws just enough to remove the old blade. NOTE: If screws are too loose, alignment of the new blade will not be accurate. NOTE: Before removing the old blades, take notice of the direction of cut as well as how the tapered edge of the old blades are oriented. The tapered edge of the new blades must be in the same orientation as the original blades, with the tapered edge on the same side as the screw heads and the flat edge facing the cutter block.  Push the blade (to the right) out of the blade holder using the tip of a screwdriver.  Remove the old blade from the blade holder. NOTE: If you cannot easily push the blade out of the blade holder after loosening the screws, use a block of wood to break the blade loose from the blade holder. Give the blade a short, sharp blow, then push it with a screwdriver to remove. If necessary, tap the block of wood sharply with a small hammer to break the blades loose.  Clean any sawdust or wood chips from around the blade area.  Slide the new blade into the slot of the blade holder.  Use a screwdriver to push the blade into the blade holder until it is centered into position.  Tighten the two screws using the blade wrench.  Repeat the above procedure to change the other blade.
