FUEL STATEMENT
Gasoline - Use 89 Octane [R+M/2] (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 I Emission Defect Warranty Explana-
tion.)
IMPORTANT
Echo Premium 2-Stroke Oil may be mixed at 50:1 ratio
for application in all Echo engines sold in the past regard-
less of ratio specified in those manuals.
Mixing Instructions
1. Fill an approved fuel container with half of the required
amount of gasoline.
2. Add 2-stroke oil to gasoline.
3. Close container and shake to mix oil with gasoline.
4. Add remaining gasoline and remix.
5. Install fuel container cap and wipe any spilled fuel from
container and surrounding area.
IMPORTANT
Stored fuel ages. Do not mix more fuel than you expect to
use in thirty (30) days, ninety (90) days when a fuel stabi-
lizer is added.
Stored two-stroke fuel may separate. ALWAYS shake fuel
container thoroughly before each use.
IMPORTANT
Spilled fuel is a leading cause of hydrocarbon emissions.
Some states may require the use of automatic fuel shut-
off containers to reduce fuel spillage. Contact your ECHO
dealer for ordering information.
CHAIN LUBRICANT
Proper lubrication of the chain while in operation reduces friction
between the chain and the guide bar to a minimum and assures
a longer service life.
• Use high quality ECHO bar and chain oil for this purpose.
• Do not use used or reclaimed oil to avoid various oiler
problems.
• Use bar and chain oil of the following grades:
SAE NO. 30 ..... in summer
SAE NO. 10 ..... in winter or when cutting resinous trees.
• When refueling, also refill chain oil.
