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 engines. Use

of diesel or 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. Diesel or alternative fuels may also cause premature

deterioration of fuel lines, gaskets, carburetors 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. ECHO Red Armor Fuel

™

(Power Fuel

™

) is 93

octane, ethanol-free fuel premixed with ECHO Red Armor

engine oil at 50:1

ratio. Use of ECHO Red Armor Fuel

™

(Power Fuel

™

) is recommended to

extend engine life in all air-cooled 2-stroke and 2/4-stroke hybrid engines.

Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738)

and J.A.S.O. FD

Standards must be used. Echo brand 2-stroke oils meet these

standards. Engine 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, such as

Echo brand 2-stroke oils, will void the two-stroke engine warranty.

Echo brand 2-stroke oils may be mixed at 50:1 ratio for application in all

Echo engines sold in the past regardless of ratio specified in those

manuals.
