when referring to the power tool reflects

be mounted on it. The term "trimmer" is 
used to designate an FS unit that is 
equipped with a nylon line head or a 
head with flexible plastic blades (i.e., the 
PolyCut head.) FS models with an "R" 
on the nameplate were originally 
configured (at the time of distribution) as 
a trimmer with a loop handle.Have your STIHL dealer show you how...

6 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....

7 NTo 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.
NIf 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

are wearing one) to suit your size before 
starting work. The machine should be 
properly balanced as specified in your 
instruction manual for proper control and 
less fatigue in operation. To be better 
prepared in case of an emergency,...
