Starting The Engine - Honda HRC7018 Owner's Manual

MAINTENANCE &ADJUSTMENTS
Gasoline is highly flammable and explosive.
You can be burned or seriously injured.
When refueling:
l
Stop engine and keep heat, sparks, and flame away.
l
Refuel only outdoors.
l
Wioe up spills immediatelv.
Never refuel the mower inside a building where fumes may
reach an open flame or spark. Keep gasoline away from
appliance pilot lights, electric motors, etc.
Refuel in a well ventilated area before starting the engine. If
the engine has been running, allow it to cool. Avoid overfilling
the tank or spilling fuel.
Spilled fuel not only creates a fire hazard, it can cause
environmental damage. Wipe up spills immediately. Dispose
of gasoline properly.
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 warranty
Fuel Recommendation
We recommend unleaded fuel because it produces fewer
engine and spark plug deposits and extends exhaust system
life.
Be sure the gasoline you use is as fresh as possible. Stale or
contaminated gasoline or an oil/gasoline mixture can
damage the engine or its fuel system. Avoid getting dirt or
water in the fuel tank.
When the engine RPM drops under heavy loads, you may
hear light "spark knock' or "pinging" (a metallic rapping
noise). This is no cause for concern.
If spark knock or pinging occurs at a steady engine speed,
under normal load, the engine can be damaged. Try using
fresh gasoline in the tank or change brands of gasoline. If
spark knock or pinging persists, contact your authorized
Honda Commercial Mower dealer.
