Saw blade won't return to 90° to table

Sawdust always will find a way to get stuck in the gears of a table saw…I just take compressed air and blow any and all dust off out of it every few days and it solves the problem for me. I have a dust nozzle with a 24 inch extension that does this job perfectly.

I go a step further and take the throat plate of the saw out and stick an electric leaf blower down through the opening to really get all the dust out. If you do this while the DC is running it will suck up any big pieces that come loose but it does still get dust everywhere if it’s been a while since you’ve cleaned the inside of the cabinet. I try to do it after every big project. My leaf blower has considerably more air “force” than a blow gun attached to my compressor. I also use it to blow dust off counters/tools and off the floor of my garage at the end of the day to keep things somewhat tidy.

Might be saw dust have something to do with it. Try to check if there’s
something unusual with it , like loosing bolts .

I leave my set for 90 off I always square the blade after every angle cut that way I know its at 90 I just took out the set screw and use my square
