N If the cap can be moved, it is not properly installed. Misalignment of the cap parts N If the cap does not drop fully into the opening when the positioning marks line up and/or if the cap does not tighten properly when twisted, the base of the cap may be rotated out of position vis-à-vis the top. N Such misalignment can result from handling, cleaning or an improper attempt at tightening. N To correct a misalignment, turn the cap (with the grip up) until it drops fully into the tank opening. N Twist the cap counterclockwise as far as it will go (approx. 1/4 turn) - this will twist the base of the cap into the correct position. N Twist the cap clockwise, closing it normally - see the sections "Closing" and "Checking for proper closure." N If your cap still does not tighten properly, it may be damaged or broken; immediately stop use of the unit and take it to your authorized STIHL dealer for repair. FC 70 C
