I recently bought a refurbished Kity 613 bandsaw and I’ve been having problems setting it up, but as I’m new to bandsaws I’m not sure if it’s me or not! I‘m aware that the Kity bandsaw is unusual in that the blade is set slightly overhanging the edge of the tyre, not the middle, but when I set the blade on the top wheel, it is almost off the bottom wheel and easily falls off when using it. I wonder if the wheels aren’t perfectly aligned and are causing this, or am I doing something wrong? Also, could it be that I’m using too thin a blade as it’s a 6.3mm blade (is there a minimum size?). The only way it will work without the blade falling off the bottom wheel is to have the top one further in than it should be. I’ve attached two photos, the one of the top wheel has the blade a few mm in from the edge, and the one of the bottom wheel has the blade overhanging the wheel. Any help gratefully received!
