fuel
NOTICE: Use of unmixed, improperly mixed, or fuel older than 90 days, (stale fuel), may cause hard starting, poor
performance, or severe engine damage and void the product warranty. Read and follow instructions in the Storage
section of this manual.
WARNING
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 alco-
hol) is NOT approved.
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 TM 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 TM , will void the two-stroke engine warranty. (Emission related parts only are covered for
two years, regardless of two-stroke oil used, per the statement listed in the Emission Defect Warranty Explanation.)
IMPORTANT
Echo premium Power Blend X TM 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.
Use Shoulder/Waist harness Use of the Shoulder/Waist Harness is
recommended for ALL Trimmer/Brush Cutter use, not just Blade oper-
ation. The Shoulder/Waist Harness when used in a trimming operation
with nylon line head suspends the trimmer from the operator's shoulder
and reduces operator fatigue.
During blade operation, the same fatigue reduction is achieved. Safety
to the operator is also enhanced by reducing the possibility of blade
contact with the operator's hands and feet by restricting trimmer move-
ment.
