FUEL TANK

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 under warranty.

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.

Running the engine with a 
low oil level can cause engine 

damage. 
The Oil Alert system (applicable engine types) will 
automatically stop the engine before the oil level falls 
below safe limit. However, to avoid the inconvenience 
of an unexpected shutdown, always check the engine 
oil level before startup.

Use unleaded gasoline with a pump octane rating of 86 or 
higher. 

These engines are 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 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

Refuel in a well-ventilated area before starting the engine. If the 
engine has been running, allow it to cool. Refuel carefully to avoid 
spilling fuel. Do not fill above the fuel strainer shoulder. After 
refueling, tighten the fuel tank cap securely. 

Never refuel the engine inside a building where gasoline fumes

damage. Wipe up spills immediately.

FUEL RECOMMENDATIONS

Place a suitable container below the engine to catch the

plug. 

Allow the used oil to drain completely, and then reinstall the 
drain plug, and tighten it securely. 

Please dispose of used motor oil in an environmental friendly 
way. We suggest you take used oil in a sealed container to 
your local recycling center or service station for reclamation. 
Do not throw it in the trash; pour it on the ground; or down a 
drain.
