|Here at Great Vacs we sometimes get asked how you adjust a kirby transmission. Sometimes if the transmission is not adjusted properly the transmission will work better one direction over the other. This just means that the transmission needs adjusted. It is fairly easy to do and does not mean that anything is wrong with your vacuum. This link is dedicated to help you adjust the transmission by yourself.
