SAFETY PRECAUTIONS
• Make sure the engine is off before you begin any maintenance or
repairs. This will eliminate several potential hazards:
– Carbon monoxide poisoning from engine exhaust.
Be sure there is adequate ventilation whenever you operate
the engine.
– 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 nonflammable 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 genuine Honda
parts or their equivalents for repair and replacement.

REFUELING
Use unleaded gasoline with a pump octane rating of 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.

spill fuel when filling your fuel tank. Damage caused by spilled fuel is
not covered under your Distributor's Limited Warranty (see page 13).
Never use stale or contaminated gasoline or oil/gasoline mixture.
