Fuel Requirements
Gasoline - Use 89 Octane [ ] (mid grade or higher) gasoline known to
be good quality. Gasoline may contain up to 15% MTBE (methyl
tertiary-butyl ether). Gasohol containing methyl (wood) alcohol is NOT
approved.
Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD
13738) and J.A.S.O. FC Standards, must be used. Echo brand Premium
50:1 oil meets these standards. Engine problems due to inadequate
lubrication caused by failure to use an ISO-L-EGD and J.A.S.O. FC
certified oil, such as Echo Premium 50:1 Two-stroke Oil, 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 EPA Phase II Emission Defect Warranty Explanation.)

Tighten guide bar nuts firmly. Move saw chain backwards on
guide bar by hand. Saw chain should move freely on guide bar if it
is in proper mesh with sprocket.
Keep the saw chain lubricated and properly adjusted and the guide bar
nuts tightened firmly at all times. If saw chain is difficult to rotate or
binds on guide bar, it is too tight.
