FUEL STATEMENT
GASOLINE - Use 89 Octane [(R+M)/2] (mid grade
or higher) gasoline or gasohol known to be good
quality.
Gasohol may contain up to 10 % Ethyl (grain)
alcohol or 15 % MTBE (methyl teriary-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 JASO
FC Standards must be used. ECHO brand premium
Power Blend™ Universal 2-Stroke Oil meets these
standards. Engine problems due to inadequate
lubrication caused by failure to use an ISO-L-EGD
and JASO FC certified oil, such as ECHO premium
Power Blend™, 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.)
HANDLING FUEL
MIXING INSTRUCTIONS -
1. Fill an approved fuel container with half of the
required amount of gasoline.
2. Add the proper amount of two-stroke oil to
gasoline.
3. Close container and shake to mix oil with
gasoline.
4. Add remaining gasoline, close fuel container,
and remix.
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.
• Stored fuel ages.
Do not mix more fuel than you expect to use in
thirty (30) days, ninety (90) days when a fuel
stabilizer is added.
• Stored two-stroke fuel may separate. ALWAYS
shake fuel container thoroughly before each
use.
AFTER USE -
DO NOT store a unit with fuel in its tank. Leaks can
occur. Return unused fuel to an approved fuel
storage container.
STORAGE -
Fuel storage laws vary by locality. Contact your
local government for the laws affecting your area.
As a precaution, store fuel in an approved, airtight
container. Store in a well-ventilated, unoccupied
building, away from sparks and flames.
IMPORTANT
• ECHO premium Power Blend™ 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 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.
DANGER
Fuel is VERY flammable. Use extreme care
when mixing, storing or handling or serious
personal injury may result.
• Use an approved fuel container.
• DO NOT smoke near fuel.
• DO NOT allow flames or sparks near fuel.
• Fuel tanks/cans may be under pressure.
Always loosen fuel caps slowly allowing
pressure to equalize.
• NEVER refuel a unit when the engine is
HOT!
• NEVER refuel a unit with the engine
running.
• DO NOT fill fuel tanks indoors.
ALWAYS fill fuel tanks outdoors over bare
ground.
• Securely tighten fuel cap after refueling.
• Inspect for fuel leakage.
If fuel leakage is found, do not start or
operate unit until leakage is repaired.
• Move at least 3 m (10 feet) from refueling
location before starting the engine.
