FUEL SYSTEM
Refueling
This engine is certified to operate on unleaded gasoline with a pump
octane rating of 86 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.
If your equipment will be used on an infrequent or intermittent basis,
please refer to the fuel section of the STORAGE chapter (page 25) for
additional information regarding fuel deterioration.
Check the fuel level by looking through the translucent fuel tank. If the
fuel level is low, refuel in a well-ventilated 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.
NOTICE
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.
Fuel Filter and Fuel Tank Cleaning
1. Remove the fuel tank cap and empty the fuel tank into an approved
gasoline container. Use a funnel to avoid spilling gasoline.
2. Pull the fuel filter out through the fuel filler neck by hooking the
black fuel supply tube with a piece of wire, such as a partly
straightened paper clip.
3. Inspect the fuel filter. If the fuel filter is dirty, remove it and wash it
with nonflammable solvent. Be careful to avoid damaging the filter.
4. Replace the filter if it is damaged or excessively dirty.
5. Rinse sediment from the fuel tank with nonflammable solvent.
6. Insert the fuel filter in the fuel tank and install the fuel tank cap.
COOLING FIN INSPECTION
1. Remove the 5 x 12 mm hex bolt and top cover. Inspect the engine
cooling fins and clean out any dirt and debris.
2. Install the top cover and 5 x 12 mm hex bolt, and then tighten
securely.
 WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured when handling fuel.
• Stop the engine and keep heat, sparks, and flame away.
