Changing the planer blades on a thickness planer is not a difficult task at all. Gather the necessary tools and follow these steps.
Step 1 - Remove Blade
Begin by unplugging the planer and removing the blade. Do this by loosening the screws that are holding the blade in and then pulling them out carefully so that you do not hurt yourself.
Step 2 - Clean Tool
Use a clean rag and wet it with water. Wipe down the planer so that there is no dust or debris left on it at all. This will help your tool to last much longer as you care for it properly.
Step 3 - Replace Blade
Once the tool has been cleaned, you can put a new blade back in. Adjust it so that it is up high enough but not too high that it might break off. Typically you will need to use your own judgment when it comes to fitting the blade. You can nip them in while you decide the right fit before you actually tighten. Then, secure the screws so that the blade is held in tightly.
