HC-2420/3020
OPERATION
Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects
away from all openings. Always stop engine, disconnect spark plug, and make sure all moving parts
have come to a complete stop before removing obstructions, clearing debris, or servicing unit.
Operation of this equipment may create sparks that can start fires. This unit is equipped with a spark
arrestor to prevent discharge of hot particles from the engine. Metal cutters can create sparks if the
cutter strikes rocks, metal, or other hard objects. Contact local fire authorities for laws or
regulations regarding fire prevention requirements.
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.

must be used. Echo brand premium Power Blend X

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.

™
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.
