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 can 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 can 
also cause premature deterioration of fuel lines, gaskets, 
carburetors and other engine components.

Fuel Requirements

Gasoline

 - Use fresh (purchased within the last 30 days from the pump) 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. 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.

2-Stroke engine oil contains petroleum distillates and other 
additives that may be harmful if swallowed. Heated oil can 
release vapors that can cause flash fire, or ignite with explosive 
force. Read and follow the oil manufacturer’s instructions, and 
observe all safety warnings and precautions for handling 
flammable liquids. For more detailed safety and first aid 
information, visit www.echo-usa.com for a copy of the Material 
Safety Data Sheet.

KEEP OUT OF REACH OF CHILDREN.
