Fortunately, most models are designed with ease of removal in mind, and are even equipped with their own special tools to remove the retaining nut and collar allowing the saws to be disassembled, reassembled and ready to cut in minutes.

Instructions

  1. 1

    Turn off your circular saw and disconnect it from its power source before removing the blade. Place your unplugged circular saw on a sturdy table or work bench with the blade facing upwards.

  2. 2

    Lift up the spring-loaded blade guard so the bottom of the saw blade is exposed. With a leather glove protecting your hand from the sharp saw teeth, grip the sides of the blade and hold it in place. Some models are equipped with a special locking pin which can be used instead to keep the blade from rotating.

  3. 3

    Loosen the retaining nut in the centre of the blade by turning it to the left using the circular saw key provided by the manufacturer or an adjustable wrench,

  4. 4

    Remove the retaining nut and slide off the collar from underneath. Place the two pieces in a safe place where you will not lose them.

  5. 5

    Lift the blade straight off of its axle.

Tips and warnings

  • The blade can be reattached or replaced with a new blade using the reverse of this process: sliding the blade onto the axle, followed by the collar and then the retaining nut which will be tightened down with the key or wrench.
  • Always turn off an unplug your circular saw before attempting to remove the blade.
  • Wear gloves when handling the blade to protect against its sharp teeth.
