Place a sharpening tool against the tip of the tooth. Open the top wheel compartment and move the tool slowly toward the blade.
Move it until it touches the front of the tooth. Now spin the upper wheel, so the blade moves upward, backward, and through the guides. When the blade moves, any protruding teeth will touch the sharpening tool. Tips will be worn down a little.
It ensures that the tips of the teeth are in the same plane. So each tooth can contribute to smoother cuts. Sometime, you’ll see not all the teeth are touching the sharpening tool.
It means the fronts of the band saw blade teeth are not aligned.
Now again, rotate the upper wheel as long as you see the marking line come all the way around.
When you reach the marking line, it means you are done with sharpening the front as well. All you have now is a sharp band saw blade.
