Allow only persons who understand this
manual to operate your trimmer. 
To receive maximum performance and
satisfaction from your STIHL trimmer, it
is important that you read and under-
stand the maintenance and safety pre-
cautions before using your trimmer. 
Contact your STIHL dealer or the STIHL
distributor for your area if you do not 
understand any of the instructions in this
manual.

:DUQLQJ

Because a trimmer is a high-speed 
cutting tool some special safety pre-
cautions must be observed to reduce
the risk of personal injury. Careless or 
improper use may cause serious or
even fatal injury. Make sure your unit is
equipped with the proper deflector, 
handle and harness for the type of 
cutting attachment being used. Always
wear proper eye protection.
STIHL’s philosophy is to continually 
improve all of its products. As a result, 
engineering changes and improve-
ments are made from time to time. If the
operating characteristics or the appear-
ance of your trimmer differ from 
those described in this manual, please
contact your STIHL dealer for informa-
tion and assistance.
