My makita 2703 blade movement quirks
Here are two links for the parts manual and the owners manual. It is not uncommon for a tool to go slightly out of line with use due to vibration and and movement of the arbor. As for the tool not tilting, it just sounds like the worm screw and gear are off line. this is a pretty quick fix but it requires you to turn your saw upside down to access the set screws. I glanced at the diagram and it looks like the handle for the adjustment is held on by a set pin. you will also be able to access this from inside the cabinet.
