If this tool is subjected to unusually high 
loads for which it was not designed (e.g. 
heavy impact or a fall), always check 
that it is in good condition before 
continuing work. Check in particular that 
the fuel system is tight (no leaks) and 
that the controls and safety devices are 
working properly. Do not continue 
operating this machine if it is damaged. 
In case of doubt, have it checked by your 
STIHL servicing dealer.
THE USE OF THE POWER TOOL
Transporting the Power Tool
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.
Warning!
Never modify this power tool in any way. 
Only attachments supplied by STIHL 
and expressly approved by STIHL for 
use with the specific STIHL model are 
authorized. Although certain unauthor-
ized attachments are useable with 
STIHL power tools, their use may, in 
fact, be extremely dangerous. For the 
cutting attachments authorized by 
STIHL for your unit, see the chapter 
"Approved Combinations of Cutting 
Attachment, Deflector, Handle and Har-
ness" in the instruction manual or the 
STIHL "Cutting Attachments, Parts & 
Accessories" catalog.
Warning!
To reduce the risk of injury from loss of 
control and blade or line contact, never 
carry or transport your power tool with 
the cutting attachment moving.
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.
