Select bare ground for fueling and move 
at least 10 feet (3 m) from the fueling 
spot before starting the engine. Wipe off 
any spilled fuel before starting your 
machine.
Different models may be equipped with 
different fuel caps.
Toolless cap with grip
To do this with this STIHL cap, 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 raised positioning 
marks on the grip of the cap and on the 
fuel tank opening lining up. Using the 
grip, press the cap down firmly while 
turning it clockwise as far as it will go 
(approx. 1/4 turn).
Misaligned, damaged or broken cap
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 prematurely 
rotated (vis-à-vis the top) to the 
closed position. Such misalignment 
can result from handling, cleaning 
or an improper attempt at 
tightening.
N To return the cap to the open 
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. Then, twist the cap 
clockwise, closing it normally.
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.
Warning!
Check for fuel leakage 
while refueling and dur-
ing operation. If fuel 
leakage is found, do not 
start or run the engine 
until the leak is fixed and 
any spilled fuel has been wiped away. 
Take care not to get fuel on your cloth-
ing. If this happens, change your 
clothing immediately.
Warning!
In order to reduce the risk of fuel spill-
age and fire from an improperly 
tightened fuel cap, correctly position 
and tighten the fuel cap in the fuel tank 
opening.
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.
