CHAIN LUBRICANT
Proper lubrication of the chain while in operation 
reduces the 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 (10 feet) from refueling 
location before starting the engine.
