blood vessel or nerve damage in the
fingers, hands, and joints of people
prone to circulation disorders or ab
normal 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. Us
ers who operate power tools on a con
tinual and regular basis must monitor
closely their physical condition and the
condition of this tool.
SPECIAL NCTICE: This unit is
equipped with a temperature limiting
muffler and spark arresting screen
which meets the requirements of Cali
fornia Codes 4442 and 4443. AIIU.S.
forest land and the states of California,
Idaho, Maine, Minnesota, New Jersey,
Oregon, and Washington require by
law that many internal combustion en
gines be equipped with a spark arrest
ing screen. If you operate in a 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. For normal homeowner use, the
muffler and spark arresting screen will
not require any service. After 50 hours
of use, we recommend that your muf
fler be serviced or replaced by a
Sears Service Center,
