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.
• 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.

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.
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 from refueling location
before starting the engine.
