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 ab- normal swellings. Prolonged use in cold weather has been linked to blood vessel dam- age 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 med- ical attention. An anti--vibration system does not guarantee the avoidance of these prob- lems. Users who operate power tools on a continual and regular basis must monitor closely their physical condition and the condi-

tion of this tool.

SPECIAL NOTICE: This unit is equipped with a temperature limiting muffler and spark arresting screen which meets the require- ments of California Codes 4442 and 4443. All U.S. forest land and the states of California, Idaho, Maine, Minnesota, New Jersey, Ore- gon, and Washington require by law that many internal combustion engines be equipped with a spark arresting screen. If you operate in a locale where such regulations ex- ist, 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 arrest- ing screen will not require any service. After 50 hours of use, we recommend that your muffler be serviced or replaced by an autho- rized service dealer.
