Brian-- yes, definitely release tension on the blade when you're not using the saw. A quick-release accessory will make it much easier and quicker to do so when you're done cutting, and more importantly, quickly pull it up to good cutting tension when you want to do some cutting. Much easier on the tires, wheel bearings, and the blade. The Carter (bearing) guides are a primo upgrade, that really improve your saw. Unfortunately, neither accessory is available for my little Delta saw, so I have to screw blade tension up and down, and every so often, adjust the cool blocks. Mustn't complain though, at least I have a bandsaw, and it'll resaw 7" (but not very fast) .
