warning
Alternative fuels, such as E-15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting ECHO requirements are
NOT
approved for use in ECHO 2-stroke gasoline engines. Use of alternative fuels may cause performance prob-
lems, 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, carbu-
retors and other engine components.
Fuel Requirements
Gasoline -
Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may contain up to
10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing methanol (wood alcohol)
is
NOT
approved.

adequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD
certified oil, such as Echo

openings. Always stop engine, disconnect spark plug, and make sure all moving parts have come to a complete stop
before removing obstructions, clearing debris, or servicing unit. Blower housing may contain shredder blades and
other sharp edges that can cause serious injuries if touched, even if engine is off and blades are not moving. Wear
gloves to protect hands from sharp edges and hot surfaces.
warning
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 blade use also can create sparks if the blade strikes rocks,
metal, or other hard objects. Contact local fire authorities for laws or regulations regarding fire prevention require-
ments.
