Yesterday, I spent (wasted) a day cleaning the gunk from the blade guard mechanism on my bandsaw for the first time in 5 years. It was coated in grease and caked sawdust. I was having a difficult time moving the wheel to raise and lower the guard. Took it apart, removed blade, blade guard. and the steel plate protecting the geared mechanism. It had the factory supplied grease imbedded and was clogged. Took quite a while to clean it all out and remove the sawdust/grease without removing the gears at all. Afterward, I am able to rotate the wheel, but it is somehow off its position, so it sticks in one spot for each rotation - I probably bent it slightly trying to move it. I applied some spray lube/ rust inhibitor and I will check it again after several uses.
Long story, but I would remove quite a bit of the grease. And I will set a regular machine maintenance routine to avoid clogs.
I am curious what opinions the experts on this forum have to say. I welcome advice as well.
