If the cap does not drop fully into the fuel tank opening when
the positioning marks (1, 2) line up, or if it does not tighten
properly when turned, the base of the cap may be
prematurely rotated in relation to the top. Such misalignment
can result from handling, cleaning or an improper attempt at
tightening.
– Illustrations A and B: The base of the cap is prematurely
rotated to the closed position and is not in the correct
starting position for installation. The tank will not seal in
this configuration. Note: in Illustrations A and B, the
interior positioning marks (1) are in line with the exterior
positioning marks (2).
– Illustration C: The bottom of the cap is in the correct
starting position for installation. Note: in Illustration C, the
interior positioning mark (1) is under the grip and not in
line with the outer positioning mark (2).

► Drop the cap into the fuel tank opening (A).
► Turn the cap counter-clockwise with slight pressure until it
drops fully into the fuel tank opening (approx. 1/4
turn) (B). This will rotate the base of the cap into the
correct starting position for installation (C). The exterior
positioning mark (1) on the cap will line up with the
"unlocked" symbol on the fuel tank housing. The interior
positioning mark (3) should be under the grip and not in
line with the outer positioning mark (1).
► Then, turn the cap clockwise, closing it normally.
► If your fuel cap still does not tighten properly, it may be
damaged or broken. Stop using the unit and take it to your
authorized STIHL dealer for repair.
