(approx. 1/4 turn). The positioning mark
on the cap should now line up with the
"closed" mark on the tank.
Fold the grip flush with
the top of the cap. Grip
the cap and check for
tightness. If the grip does
not lie completely flush
with the cap and the
detent on the grip does
not fit in the correspond-
ing recess in the filler
opening, or if the cap is
loose in the filler opening,
the cap is not properly
seated and tightened and
you must repeat the
above steps.
Misaligned, damaged or broken cap
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 prematurely
rotated (in relation to the top) to the
closed position. Such misalignment
can result from handling, cleaning
or an improper attempt at
tightening.

Left: Bottom of cap in closed posi-
tion – inner mark (1) in line
with outer mark.
Right: Bottom of cap in correct posi-
tion for installation – inner
mark is under the grip and
not in line with the outer
mark.
To return the cap to the open
N
position for installation, turn the cap
(with the grip up) until it drops fully
into the tank opening. Next, 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 for installation. Then, twist
the cap clockwise, closing it
normally.
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.
See also the "Fueling" chapter in your
Instruction Manual for additional
information.
Before Operation
Take off the chain guard (scabbard) and
inspect the chain saw for proper
condition and operation. (See the
maintenance chart near the end of the
instruction manual.)
WARNING
Always check your chain saw for proper
condition and operation before starting,
particularly the throttle trigger, throttle
trigger lockout, stop switch and cutting
attachment. The throttle trigger must
move freely and always spring back to
the idle position. The Master Control
Lever / stop switch must move easily to
STOP, 0 or †. Never attempt to modify
the controls or safety devices.
WARNING
Check fuel system for leaks, especially
the visible parts, e.g., filler cap, hose
connections, manual fuel pump (only for
chain saws equipped with a manual fuel
pump). Do not start the engine if there
are leaks or damage – risk of fire! Have
the chain saw repaired by a STIHL
servicing dealer before using it.
WARNING
Check that the spark plug boot is
securely mounted on the spark plug – a
loose boot may cause arcing that could
ignite combustible fumes and cause a
fire.
