Follow these steps to loosen the blade nut:
- Make sure the saw is switched off and the power cord is unplugged to prevent any accidents.
- Locate the blade nut on the front of the saw. It is usually a large, round nut that holds the blade in place.
- Using a wrench or a socket set, turn the blade nut counterclockwise to loosen it. The nut may be tight, so you may need to apply some force.
- Once the blade nut is loose, keep turning it until you can remove it completely.
- Set the blade nut aside in a safe place.
Now that the blade nut is loosened, you can proceed to remove the old blade and install a new one. Refer to the user manual or manufacturer’s instructions for further guidance on blade replacement.
