Contents
This manual contains operating and
safety instructions for all STIHL
Professional Tree Service Chain Saws.
A professional tree service chain saw is
designed especially for in-tree
maintenance, tree surgery and other
cutting work in confined spaces such as
working from a rope and harness or from
a lift-bucket.
Allow only persons who fully understand
this manual to operate your chain saw.
To receive maximum performance and
satisfaction from your STIHL chain saw,
it is important that you read, understand
and follow the safety precautions and
the operating and maintenance
instructions in chapter "Safety
Precautions for Chain saw Users" and
"Safety Precautions" before using your
chain saw. For further information you
can go to www.stihlusa.com.
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 chain saw 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.
