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 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. M345-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.
• Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to
equalize.
• NEVER refuel a unit when the engine is HOT or RUNNING!
• DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground.
