N Remove the filler cap.
Refueling
Take care not to spill fuel while fueling
and do not overfill the tank – leave
approx. 1/2" (13 mm) air space.
Closing
Handle is in an upright position:
N Insert the cap – positioning marks
on the cap and the fuel tank opening
must line up.
N The cap should drop fully into the
opening in this position.
N Push the filler cap down and twist it
clockwise until it engages.
N Flip the handle down.
Checking for proper closure
N The lug on the grip must engage
entirely in the recess (arrow), and
the grip must lie completely flush
with the top of the cap.
N Grip the cap and check for
tightness.
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.
