It may be carried only in a horizontal 
position. Grip the shaft in a manner that 
the machine is balanced horizontally. 
Keep the hot muffler away from your 
body and the cutting attachment behind 
you.
Fuel
Your STIHL power tool uses an oil- 
gasoline mixture for fuel (see the 
chapter on "Fuel" of your instruction 
manual).
Fueling Instructions
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 power tool 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 
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 
Warning!
Always shut off the engine and make 
sure the cutting attachment has stopped 
before putting a trimmer / brushcutter 
down. When transporting it in a vehicle, 
properly secure it to prevent turnover, 
fuel spillage and damage to the unit. 
STIHL recommends that you keep 
metal blades covered with the transport 
guard (optional accessory).
Warning!
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 power tool. Note that 
combustible fuel vapor may escape 
from the fuel system.
Warning!
To reduce the risk of serious injury from 
burns, never attempt to refuel the unit 
until it has been completely removed 
from the operator.
Warning!
Fuel your power tool in well-ventilated 
areas, outdoors. Always shut off the 
engine and allow it to cool before refu-
eling. Gasoline vapor pressure may 
build up inside the fuel tank depending 
on the fuel used, the weather conditions 
and the tank venting system.
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.
