OPERATION
Fuel
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 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.
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 brand Power Fuel
™ is 93 octane, ethanol-free fuel
premixed with ECHO Red Armor ® engine oil at 50:1 ratio. Use of ECHO 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 premium Power Blend X
™ Universal 2-Stroke Oil meets 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. FD certified oil, such as Echo premium Power Blend X
™ , will void the two-stroke engine warranty.
Echo premium Power Blend X ™ Universal 2-Stroke Oil may be mixed at 50:1 ratio for application in all Echo
engines sold in the past regardless of ratio specified in those manuals.
Handling Fuel
Fuel is VERY flammable. Use extreme care when mixing, storing or handling, or serious personal
injury may result.
• Use an approved fuel container.
•
DO NOT smoke near fuel.
•
DO NOT allow flames or sparks near fuel.
