Closing
With grip 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 While pressing the cap down, twist it
firmly clockwise as far as it will go
(approx. 1/4 turn).
N Fold down the grip.

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.
Left: Base of improperly aligned
cap (with open space)
Right: Base of cap correctly posi-
tioned for installation
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.
