    • To ensure that you do not get grease and dirt on your table or floor, lay a towel down before you begin working.

    • The grease from the circular saw can stain your towel so a dirty towel or work rag is recommended.

    • With your Phillips screwdriver, unscrew all 7 of the 20 mm screws on the handle of the circular saw.

    • There is one 25 mm screw that goes in the hole circled in red.

    • Unscrew the forked screw head

    • Lift off the top half of the handle.

    • Unscrew the two wide-head 20 mm screws holding the remaining half of the handle to the motor.

    • Remove the remaining half of the handle from the motor by lifting it over the screw that is keeping it in place.

    • Using a crescent wrench, unscrew the hex washer head screw that is holding the blade in place.

    • Lift the blade over the internally threaded screw and pull it off of the saw.

    • If the hex washer head screw rotates but does not loosen or if the whole blade rotates as you turn your wrench, giving the wrench a quick jerk should loosen the screw.

    • Remove the blade cover by applying upward pressure until it unsnaps from the washer.

    • The blade cover will come off easier if it is facing away from the rest of the saw (see second picture).

    • Unscrew the 70 mm screw that is inside the black tube (see first picture).

    • Unscrew the five screws as highlighted in the second picture. The bottom left is a 70 mm screw and the other four are 20 mm screws.

    • Unscrewing the remaining four 20 mm screws are unnecessary unless you wish to repair or replace the cogs in the saw.

    • The motor will now be loose and you should be able to twist the motor in a counter-clockwise direction until it is able to be pulled off.

Conclusion
