Fuel
Your STIHL chain saw uses an oil- 
gasoline mixture for fuel (see the 
chapter on "Fuel" of your instruction 
manual).
WARNING
Fueling Instructions
WARNING
Fuel your chain saw in well-ventilated 
areas, outdoors. Always shut off the 
engine and allow it to cool before 
refueling. Gasoline vapor pressure may 
build up inside the fuel tank depending 
on the fuel used, the weather conditions 
and the tank venting system.
In order to reduce the risk of burns and 
other personal injury from escaping gas 
vapor and fumes, remove the fuel filler 
cap on your chain saw carefully so as to 
allow any pressure build-up in the tank 
to release slowly. Never remove the fuel 
filler cap while the engine is running.
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 
chain saw.
WARNING
Different models may be equipped with 
different fuel caps.
Toolless cap with grip
WARNING
In order to reduce the risk of fuel spillage 
and fire from an improperly tightened 
fuel cap, correctly position and tighten 
the fuel cap in the fuel tank opening.
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 with the positioning mark on the 
grip of the cap and the "open" mark 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). The positioning mark 
on the cap should now line up with the 
"closed" mark on the tank.
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 (in relation to the top) to the 
closed position. Such misalignment 
can result from handling, cleaning 
or an improper attempt at 
tightening.
Gasoline is an extremely 
flammable fuel. If spilled 
and ignited by a spark or 
other ignition source, it 
can cause fire and seri
-
ous burn injury or 
property damage. Use 
extreme caution when 
handling gasoline or fuel 
mix. Do not smoke or 
bring any fire or flame 
near the fuel or the chain 
saw. Note that combusti
-
ble fuel vapor may 
escape from the fuel 
system.
Check for fuel leakage 
while refueling and during 
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 
clothing. If this happens, 
change your clothing 
immediately.
