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.

This engine is certified to operate on unleaded gasoline with a
pump octane rating of 86 or higher (a research octane rating of 91

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

this engine for refuelling.
Refuel in a well-ventilated area before starting the engine. If the
engine has been running, allow it to cool. Refuel carefully to avoid
spilling fuel. It may be necessary to lower the fuel level depending
on operating conditions. After refueling, tighten the fuel tank 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.
