State and Local Requirements Your saw is equipped with a temperature limiting muffler, a spark arresting screen and dual bucking spikes in order to comply with the requirements of SAE Recommended Practice J335 and California Codes 4442 and 4443. All national forest land and land managed by the states of California, Maine, Washing- ton, and Oregon require internal combustion engines to be equipped with a spark arrester screen by law. Other states and federal agencies are enacting similar regulations. 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 a law . Spark arrester maintenance is described in the Maintenance-Spark Arresting Muffler Section of the manual. WARNING Muffler surfaces are very hot during and after operation of the chain saw, keep all body parts away from the muffler. Serious burns may occur if contact is made with the muffler. WARNING Exposure to vibrations through prolonged use of gaso- line powered hand tools could cause blood vessel or nerve damage in the fingers, hands, and wrists of people prone to circulation disorders or abnormal swell- ings. 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 wrists, discontinue the use of this tool and seek medical attention. 5 English
