Three things come to mind:
1) Metal cutting blades do not have the same tooth geometry as wood cutting blades. You may need to change the blade.
2) Blade (wheel) speed. I don't have at my fingertips the desired linear speed of the blade for cutting wood. It is probably something that could be found in the manual for a similarly sized Jet or Delta or whatever brand bandsaw. Adjust the metal cutting saw as closely as possible.
3) I have access to a machine shop for occasional use. They have a nice large vertical metal cutting bandsaw and other metal working tools. However they have a very strong bias against running any wood through them simply because it has the potential for leaving behind sawdust. The story I was given is that in the past they did allow it but the sawdust built up too much, mixed with the cutting oil in some cases making a putty. And in one extreme case on a stationary beltsander, the sawdust caught fire due to sparking.
So, blade, speed and clean up before AND after.
