How do I replace the blade on a circular saw?

  1. Unplug the saw.
  2. Immobilize the saw blade either with the button provided for this purpose which is located somewhere on the body of the saw, or by use of some locking pliers, or a pin under one of the teath (do not damage the cutting tips with something hard.
  3. Loosen the threaded bolt in the center of the blade until it comes off.
  4. Replace with a new blade, and reverse the steps.
