Using the grip, press the cap down firmly while
turning it clockwise to the closed position
(approximately 1/4 turn). In the closed position, the
interior (4) and exterior (1) positioning marks will
align with the "locked" symbol (3) on the fuel tank
housing.
–
Fold the grip flush with the top of the cap and check
for tightness.
–
If the grip does not lie completely flush with the cap
