Allow only persons who understand this 
Manual to operate your chainsaw.
To receive maximum performance and 
satisfaction from your STIHL chainsaw, 
it is important that you read and 
understand 
the maintenance and safety 
precautions,
 starting on page 3, before 
using your chainsaw. 
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 chainsaw is a high-speed 
wood-cutting tool, some special safety 
precautions must be observed as with 
any other power saw to reduce the risk 
of personal injury. 
Careless or improper use may cause 
serious or even fatal injury.
STIHL's philosophy is to continually 
improve all of its products. As a result, 
engineering changes and improvements 
are made from time-to-time. If the 
operating characteristics or the 
appearance of your chainsaw differs 
from those described in this Manual, 
please contact your STIHL dealer for 
information and assistance.
