I've been using my new circular saw for about a week. Today while making a plunge cut it just locked. It didn't get stuck on anything inside the board and it consistently locked every time I tried to cut something with it afterwards. Is there anything I can do about that other than invoke the warranty?
Update
Problem solved. The nut holding the blade down was coming loose. I'm new to power saws and didn't even think to check that. :/
Next problem. I tightened the nut as tight as it goes. Is it normal to have to do this after every single cut?
Best Answer
It is unusual to need to retighten the nut. If one side of the nut is concave, ensure that side is against the blade.
