This engine is certified to operate on unleaded gasoline  

with a pump octane rating of 93 or higher. 

You may use regular unleaded gasoline containing no  

more than 10% ethanol (E10) or 5% methanol by volume.  

In addition, methanol must contain cosolvents and  

corrosion inhibitors. Use of fuels with content of ethanol or  

methanol greater than shown above may cause starting 

and/or performance problems. It may also damage metal,  

rubber, and plastic parts of the fuel system. Engine  

damage or performance problems that result from using a  

fuel with percentages of ethanol or methanol greater than  

shown above are not covered by warranty. 

Check the fuel level by looking through the translucent  

fuel tank. If the fuel level is low, refuel in a well-ventilate   

d 

area with the engine stopped. If the engine has been  

running, allow it to cool first. 

Never use stale or contaminated gasoline or an  

oil/gasoline mixture. 

Avoid getting dirt or water in the fuel tank. 

To refuel, rest the trimmer on the ground with the fuel  

tank cap facing up, as shown. Remove the fuel tank cap  

and fill the tank with gasoline to the bottom of the filler  

neck. Refuel carefully to avoid spilling fuel. 

Do not overfill. There should be no fuel in the filler neck.  

After refueling, tighten the fuel tank cap securely. 

Never refuel the engine inside a building where gasoline  

fumes may reach flames or sparks. Keep gasoline away  

from appliance pilot lights, barbecues, electric appliances,  

power tools, etc. 

Spilled fuel is not only a fire hazard, it causes  

environmental damage. Wipe up spills immediately. 

Move at least 10 feet (3 meters) away from the fueling  

source and site before starting the engine. 

Fuel can damage paint and plastic. Be careful not to spill  

fuel when filling your fuel tank. Damage caused by spilled  

fuel is not covered under warranty.
