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 hedge trimmer differs from
those described in this manual, please
contact your STIHL dealer for
information and assistance.
