5 IMPORTANT SAFETY INSTRUCTIONS
￭ An improperly tightened fuel filler cap can loosen or come
off and spill quantities of fuel. To reduce the risk of fuel
spillage and fire from an improperly installed fuel cap,
correctly position and tighten the cap in the fuel tank
opening:
– Raise the grip on the top of the cap until it is upright
at a 90° angle. Insert the cap in the fuel tank opening
with the exterior positioning mark (1) lined up with
the "unlocked" symbol (2) on the fuel tank housing.
– 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
or the detent on the grip does not fit in the
corresponding recess in the tank opening, or if the
cap is loose, the cap is not properly seated and you
must repeat the above steps. Refer to the procedure
below for returning the base of the cap to the proper
starting position for installation.

￭ 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).

￭ To return the base of the cap to the proper starting
position for installation:
– 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.
