Replacing the planer knives on your DEWALT DW735 Portable Thickness Planer involves several steps. First, disconnect the planer from its power source and ensure it's turned off for safety. Remove the top cover by unscrewing the four screws located on the top. Next, detach the dust shroud by removing the three wing nuts and sliding the shroud to the left to disengage it from the fan housing, then set it aside. Use a piece of scrap wood to carefully rotate the cutter head until you can access the eight screws in the knife clamp; the cutter head lock lever should engage to prevent further rotation. Use a T-wrench to remove these eight screws and place them in a small container to avoid losing them. The T-wrench's magnets can then attract and lift the knife clamp, exposing a knife. Use the magnet to lift the knife itself, avoiding direct contact with your fingers. If only one side of the knife is worn, flip it so the sharp, unused edge is ready for use, ensuring the oblong holes align with the pins on the cutter head. Replace the knife clamp, aligning the beveled edge with the knife's cutting edge, and tighten the screws. To access the other knives, disengage the cutter head lock lever and rotate the cutter head until it locks, revealing the next knife clamp; repeat the knife replacement process. After all knives are replaced, reattach the dust shroud, securing it with the wing nuts, and replace the top cover. Finally, run the planer for about 10 minutes to help seat the new knives before using the DEWALT DW735.
