SAFETY NOTICE:
Exposure to vibrations
through prolonged use of gasoline powered
hand tools could cause blood vessel or nerve
damage in the fingers, hands, and joints of
people prone to circulation disorders or
abnormal swellings. Prolonged use in cold
weather has been linked to blood vessel
damage in otherwise healthy people. If
symptoms occur such as numbness, pain,
loss of strength, change in skin color or texture,
or loss of feeling in the fingers, hands, or joints,
discontinue the use of this tool and seek
medical attention. An anti-vibration system
does not guarantee the avoidance of these
problems. Users who operate power tools on
a continual and regular basis must monitor
closely their physical condition and the
condition of this tool.

Your saw is equipped
with a temperature limiting muffler and spark
arresting
screen

Jersey, Oregon, and Washington require by
law that many internal combustion engines
to be equipped with a spark arresting screen.
