While temporary tightening, you may hear the “click” sound. But do not stop tightening at that time. This sound does not mean that the saw chain and guide bar were assembled.
5.While holding the chain cover, temporary tighten the nut assembly and fix the bar and chain cover. (You can fix them even by tightening the lever.)
Check if the saw chain fits on the bar rail. If not, readjust by loosen the nut assembly.
