Handling Fuel
WARNING 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 or RUNNING!
• DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks
outdoors over bare ground.
• DO NOT overfill fuel tank. Wipe up spills immediately.
• Securely tighten fuel tank cap and close fuel container after
refueling.
• Inspect for fuel leakage. If fuel leakage is found, do not start
or operate unit until leakage is repaired.
• Move at least 3m (10 ft.) from refueling location before
starting the engine.
Mixing Instructions
1. Fill an approved fuel container with half of the required amount
of gasoline.
2. Add the proper amount of 2-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 hydrocar-
bon emissions. Some states may require
the use of automatic fuel shut-off containers
to reduce fuel spillage.
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
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.
IMPORTANT
Stored two-stroke fuel may separate.
ALWAYS shake fuel container thoroughly
before each use.
IMPORTANT
Echo premium Power Blend
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.
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 bar and chain oil of high quality for this purpose.
• Do not use used or reclaimed oil to avoid various oiler
problems.
• Use ECHO bar and chain oil.
• When ECHO bar and chain oil is not available:
Use motor oil, etc.
• 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.
