have come to a complete stop before removing obstructions, clearing debris, or servicing unit.
Operation of this equipment may create sparks that can start fires. This unit is equipped with a spark
arrestor to prevent discharge of hot particles from the engine. Metal cutters can create sparks if the

requirements are NOT approved for use in ECHO 2-stroke gasoline engines. Use of alternative fuels
may cause performance problems, loss of power, overheating, fuel vapor lock, and unintended
machine operation, including, but not limited to, improper clutch engagement. Alternative fuels may
also cause premature deterioration of fuel lines, gaskets, carburetors and other engine components.
