Well, I used my BT3100 for the first time today. I set the blade at max height to cut a large 4x4, a job it handled admirably. However, when I tried to lower the blade it wasn't going anywhere... Turning the crank in either direction yielded nothing.
So I spent a good 30-40 minutes poking around under there. I tried lubing somethings up, etc. Here's the deal - the selection knob works fine (i.e. angle v. blade height), and I can change the angle just fine. But the crank just doesn't affect blade height when that selection knob is set to lock angle and adjust height.
The shaft moves a little bit and moves that first gear just a little bit, but once it meets any resistance (i.e from the inertia of the second gear, the on that sits on the worm and raises or lowers it) it stops.
So I tried taking things apart starting with the crank. I was able to loosen but not tighten that hex nut on the face that holds it in. I need to get the proper sized allen wrench - headed to HF tomorrow to get it. I hope that's the problem, i.e. that I just loosened that handle somehow.
Any other ideas? Anyone else ever have this happen to them?
Also, how dangerous is it to use the blade at its highest setting for the time being? I am done cutting 4x4s and need to crosscut some 2x6s. I am inclined to hold off until I get this fixed. Good idea?
