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.
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.
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.
Chain Lubricant
Note: Cap indication - Fuel/oil tanks are indicated by the following illustrations
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.
