As I was putting the saw blade on my new Ryobi Circular saw my finger slipped off of the blade lock button while tightening and now I cannot get the blade lock to engage again. What would be the fix for this?

    What happens with the button or lever? Is it jammed or does it move freely? Often a little tapping with a block of wood jars things loose. You might also drizzle a little household oil into the mechanism. – isherwood Sep 24 '19 at 20:37

    Have you tried rotating the spindle? – Harper - Reinstate Monica Sep 24 '19 at 21:41
  • Is it still under warranty? – JACK Sep 25 '19 at 0:09
  • I don't know what happened to the button. I was tightening and my finger slipped off while I was turning the wrench and disengaged the blade lock. Now it won't lock. I am going to try hitting it as suggested. I did give it some oil before I put on the blade. If that does not work I will try the screw driver to block it from turning as Nate suggested. If those things do not work I will return it to the store as it is brand new. This is my first time using it. Thank you for all of your suggestions. – PlanoKathy Sep 25 '19 at 16:21

Thank you everyone for your suggestions. I tried the screwdriver but the blade still turned so I knocked it on the bolt with the handle of the screwdriver and that did the trick. Holding that engage button down is hard for small hands so I am sure I will make this mistake again. Thanks again.

  • Good deal. Don't forget to accept your answer to resolve the question. – isherwood Oct 25 '19 at 18:38

You can probably use a screwdriver between the teeth of the blade and the guard to prevent the spindle from turning while you wrench on the nut. I bought a used miter saw a few years ago with a broken spindle lock and this is how I change the blade on that. If it's under warranty, I wouldn't recommend you try to fix it yourself, and instead send it out for repair according to the manufacturers' guidance.

  • Thank you Nate. I will try this. – PlanoKathy Sep 25 '19 at 16:22
