WARNING

DANGER

Alternative fuels, such as E-20 (20% 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

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.

GASOLINE - Use 89 Octane [R+M/2] (mid grade or higher) gasoline or gasohol known to be good quality. Gasohol

may contain up to 10% Ethyl (grain) alcohol or 15% MTBE (methyl tertiary-butyl ether). Gasohol containing methyl

(wood) alcohol is

NOT approved.

used. Echo brand premium Power Blend

TM

Universal 2-Stroke Oil meets these standards. Engine problems due to

inadequate lubrication caused by failure to use an ISO-L-EGD and J.A.S.O. FC certified oil, such as Echo premium

Power Blend

TM

, will void the two-stroke engine warranty. (Emission related parts only are covered for two years, re-

gardless of two-stroke oil used, per the statement listed in the Emission Defect Warranty Explanation.)
