REFUELING
Recommended Fuel
Unleaded gasoline
Research octane rating 91 or higher
Pump octane rating 86 or higher
This engine is certified to operate on unleaded gasoline with a
research octane rating of 91 or higher (a pump octane rating of 86
or higher).
Refuel in a well ventilated area with the engine stopped. If the
engine has been running, allow it to cool first. Never refuel the
engine inside a building where gasoline fumes may reach flames
or sparks.
You may use 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 under the Warranty.
If your equipment will be used on an infrequent or intermittent
basis, please refer to the ''Fuel'' section of the STORING YOUR
ENGINE chapter (see page 11) for additional information
regarding fuel deterioration.
Never use stale or contaminated gasoline or an oil/gasoline
mixture. Avoid getting dirt or water in the fuel tank.
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when refueling.
• Stop the engine and keep heat, sparks, and flame
away.
• Refuel only outdoors.
• Wipe up spills immediately.
Fuel can damage paint and some types of plastic. Be careful not to
spill fuel when filling your fuel tank. Damage caused by spilled
fuel is not covered under the Warranty.
For refueling, refer to the manufacturer's instructions provided
with the equipment. See the following for a Honda supplied
standard fuel tank refueling instruction.
1. With the engine stopped and on a level surface, remove the
fuel filler cap and check the fuel level. Refill the tank if the fuel
level is low.
2. Add fuel to the maximum fuel level of the fuel tank. Do not fill
the fuel tank completely. Do not overfill. Wipe up spilled fuel
before starting the engine.

3. Refuel carefully to avoid spilling fuel. Fill tank to approximately
50 mm below the top of the fuel tank. It may be necessary to
lower the fuel level depending on operating conditions. After
refueling, tighten the fuel filler cap securely.
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.
ENGINE OIL
Oil is a major factor affecting performance and service life.
Use 4-stroke automotive detergent oil.
Recommended Oil
Use 4-stroke motor oil that meets or exceeds the requirements for
API service category SE or later (or equivalent). Always check the
API service label on the oil container to be sure it includes the
letters SE or later (or equivalent).
SAE 10W-30 is recommended for general use. Other viscosities
shown in the chart may be used when the average temperature in
your area is within the indicated range.
Wash your hands with soap and water after handling used oil.
