OPERATION
Fuel
Diesel fuels and 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 engine
s.
Use
of diesel or alternative fuels can cause performance
problems, loss of power, overheating, fuel vapor lock, a
nd
un
intended machine operation, including, but not limite
d to,
improp
er clutch engagement. Diesel or alternative fuels can
also cause premature deterioration of fuel lines, gasket
s,
c
arburetors and other engine components.
Fuel Requirements
Gasoline - Use fresh (purchased within the last 30 days from the pump) 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. Use of ECHO branded fuel is recommended to extend
engine life in all air-cooled 2-stroke and 2/4-stroke hybrid engines.

oils, meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD

problems due to inadequate lubrication caused by failure to use an ISO-L-
EGD (ISO/CD 13738) and J.A.S.O. M345-FD
certified oil will void the two-
stroke engine warranty.
2-Stroke engine oil contains petroleum distillates and other
a
dditives that may be harmful if swallowed. Heated oil
can
