OPERATION

WARNING
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. Blower housing may contain shredder blades and other sharp edges that can
cause serious injuries if touched, even if engine is off and blades are not moving. Wear gloves to protect hands from sharp
edges and hot surfaces.
WARNING
Operation of this equipment may create sparks that can start fires around dry vegetation. This unit is equipped with a spark
arrestor to prevent discharge of hot particles from the engine. Contact local fire authorities for laws or regulations regarding
fire prevention requirements.
WARNING
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a poison gas. Breathing CO can cause unconsciousness, seri-
ous injury, or death. Exhaust can cause serious burns. ALWAYS position unit so that exhaust is directed away from your face
and body.
WARNING
• Always maintain a direct, clear line of site to the unit and the work being performed.
• Always be alert for changes in operation of unit.
• Always shut engine off before transporting unit to new location.

Fuel

WARNING
Diesel fuels and alternative fuels, such as E-15 (15% ethanol), E -85 (85% ethanol) or any fuels not meeting ECHO require-
ments 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, improp-
er 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 ap-
proved. Use of ECHO branded 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, such as ECHO branded 2-stroke oils, meeting ISO-L-EGD (ISO/CD 13738) and
J.A.S.O. FD Standards must be used. ECHO branded 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 will void the two-stroke
engine warranty.
