REFUELING

Recommended Fuel
Unleaded gasoline
U.S. Pump octane rating 86 or higher
Except U.S. Research octane rating 91 or higher
Pump octane rating 86 or higher
This engine is certified to operate on unleaded gasoline. Unleaded
gasoline produces fewer engine and spark plug deposits and
extends exhaust system life.
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when refueling.
Stop 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 Distributor's Limited Warranty.
Never use stale or contaminated gasoline or oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
Occasionally you may hear a light ''spark knock'' or ''pinging''
(metallic rapping noise) while operating under heavy loads. This is
no cause for concern.
If spark knock or pinging occurs at a steady engine speed, under
normal load, change brands of gasoline. If spark knock or pinging
persists, see an authorized Honda servicing dealer.
Running the engine with persistent spark knock or pinging can
cause engine damage.
Running the engine with persistent spark knock or pinging is
considered misuse, and the Distributor's Limited Warranty does
not cover parts damaged by misuse.
1. Check the fuel level by looking through the translucent fuel tank.
2. 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.
Standard/Pump type:
FUEL FILLER CAP
8
Tiller type:
MAXIMUM
FUEL LEVEL
To refuel, rest the engine on the ground with the fuel filler cap
facing up, as shown. Remove the fuel filler 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 filler 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.

equivalent. Always check the
API service label on the oil
container to be sure it includes
