Step 1:  Unplug the power cord of the saw from the power socket. Or remove the battery if it is a cordless saw.

Step 2: Try to figure out where the saw blade lock is and press that saw lock button (refer to your user manual to locate the lock button) then turn the blade until the locking mechanism engages.

Step 3: Use the wrench provided with your saw to remove the nut from the shaft that holds the blade in place. To loosen the nut, turn the key in the same direction as the blade.

Step 4: Retract the top guard of the saw blade and remove the old one.

Step 5: Slide the new blade onto the saw shaft, making sure that the saw teeth are oriented in the correct direction of rotation. If you are unsure, refer to the arrow on the saw blade.

Step 6: Use the same wrench to tighten the shaft nut until it is tight. Be careful not to over tighten the nut as it will be difficult to loosen it the next time you replace the blade.
