Fuel Recommendations

Use gasoline wi.th a pump octane rating of 86 or higher.

We recommend unleaded fuel because it 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 lawn mower dealer.

1 NOTICE 1

Running the engine with persistent spark knock or pinging can

cause engine damage.

Running the engine with persistent spark knock or pinging is

misuse, and the Distributor’s Limited Warranty does not cover

parts damaged by misuse.
