As Matt says wheel 01 is nothing to do with focusing, it just locks or unlocks the lens board so it can be tilted to correct verticals. Wheel 02 is the focusing wheel and if turning this does not move the bellows then it appears there is a fault somewhere. It might be worth lifting off the top half of the head to see what is happening inside. The instructions given by Matt should show you how to remove the top of the head.
