Warning: This unit is equipped with an internal combustion engine and should not be used on or near any unimproved forest-covered, brush-
covered or grass-covered land unless the engine’s exhaust system is equipped with a spark arrester meeting applicable local or state laws (if any).
If a spark arrester is used, it should be maintained in effective working order by the operator. In the State of California the above is required by law
(Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. A spark arrester
