WARNING:
The engine exhaust

birth defects or other reproductive harm.
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.
SPECIAL NOTICE:
Your saw is equipped
with a temperature limiting muffler and spark
arresting
screen
which
meets
the
requirements of California Codes 4442 and
4443. All U.S. forest land and the states of
California, Idaho, Maine, Minnesota, New
Jersey, Oregon, and Washington require by
law that many internal combustion engines to
be equipped with a spark arresting screen. If
you operate a chain saw in a state or locale
where such regulations exist, you are legally
responsible for maintaining the operating
condition of these parts. Failure to do so is a
violation of the law. Refer to the SERVICE

screen. Failure to follow all Safety Rules and
Precautions can result in serious injury. If
