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.

Move at least 10 feet (3 meters) away from the fueling source and site 
before starting the engine.

Fuel can damage paint and plastic. Be careful not to spill fuel when 
filling your fuel tank. Damage caused by spilled fuel is not covered by 
the Distributor’s Limited Warranty (page 72).

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.

Never use stale or contaminated gasoline or an oil/gasoline mixture. 
Avoid getting dirt or water in the fuel tank.

Occasionally you may hear 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.

This is considered misuse, and the Distributor’s Limited Warranty 
(page 72) does not cover parts damaged by misuse.
