SAFETY PRECAUTIONS
• Make sure the engine is off before you begin any maintenance
or repairs. To prevent accidental startup, disconnect the spark
plug cap. This will eliminate several potential hazards:
– Carbon monoxide poisoning from engine exhaust.
Operate outside, away from open windows or doors.
– Burns from hot parts.
Let the engine and exhaust system cool before touching.
– Injury from moving parts.
Do not run the engine unless instructed to do so.
• Read the instructions before you begin, and make sure you
have the tools and skills required.
• To reduce the possibility of fire or explosion, be careful when
working around gasoline. Use only a non-flammable solvent,
not gasoline, to clean parts. Keep cigarettes, sparks and flames
away from all fuel related parts.
Remember that an authorized Honda servicing dealer knows your
engine best and is fully equipped to maintain and repair it.
To ensure the best quality and reliability, use only new Honda
Genuine parts or their equivalents for repair and replacement.

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
