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. 

Oil tank cap

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.
