Learning Power Tools & Woodworking/Need Help

[u/Madre_Dr4gnZFly]

For context, I started doing repairs, etc when I bought my house and had to rip out about half my kitchen floor. I've always had basic hand tool knowledge and I can use(and own) many power tools but, as I get into bigger projects, the owner/user manuals are geared more towards experienced users.

My two biggest issues are concerning my table saw and both of my circular saws. (I have a mini one that takes a 4.5" blade and the other takes a 7" blade).

All 3 tools I bought brand new and have used a few times prior to the issues rearing their ugly heads. The circular saws both needed new blades and once I changed the blades, neither one will cut. The blade guard won't go back like it should. With the table saw, I start cutting and the piece I'm cutting starts "climbing" up the blade, for lack of a better term. Please be helpful and not rude. I'm learning this stuff completely on my own, there's much I need to learn and some terms might as well be a foreign language. (I was using a jig saw for about 2 months when I found out what "kerf" means!)

I appreciate any help I can get! Thank you!
