Checking for proper closure
The lug on the grip must engage
N
entirely in the recess (arrow), and
the grip must lie completely flush
with the top of the cap.
Grip the cap and check for
N
tightness.
If the cap can be moved, it is not
N
properly installed.
Misalignment of the cap parts
If the cap does not drop fully into the
N
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.
Such misalignment can result from
N
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
To correct a misalignment, turn the
N
cap (with the grip up) until it drops
fully into the tank opening.
Twist the cap counterclockwise as
N
far as it will go (approx. 1/4 turn) –
this will twist the base of the cap into
the correct position.
Twist the cap clockwise, closing it
N
normally – see the sections
"Closing" and "Checking for proper
closure."
If your cap still does not tighten
N
properly, it may be damaged or
broken; immediately stop use of the
unit and take it to your authorized
STIHL dealer for repair.
Opening the threaded filler cap
Turn the cap counterclockwise until
N
it can be removed from the tank
opening.
Remove the filler cap.

Refueling
Take care not to spill fuel while fueling
and do not overfill the tank. STIHL
recommends use of the STIHL filling
system (special accessory).
Closing the threaded filler cap
Position cap.
N
Turn the cap clockwise as far as it
N
will go and tighten it as securely as
possible by hand.
