Allow only persons who understand this
manual to operate your clearing saw.
To receive maximum performance and
satisfaction from your STIHL brush-
cutter, it is important that you read and
understand the maintenance and safety
precautions, starting on page 3, before
using your clearing saw.
Contact your STIHL dealer or the STIHL
distributor for your area if you do not
understand any of the instructions in this
manual.
!Warning!
Because a clearing saw 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 clearing saw differs from
those described in this manual, please
contact your STIHL dealer for informa-
tion and assistance.
