Fuel Recommendation
1. Check the fuel level gauge.
2. Refill the tank if the fuel level is low. Do not fill above the shoulder of the fuel strainer.
WARNING
Gasoline is extremely flammable and is explosive under certain conditions. Refuel in a
well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the
area where the engine is refueled or where gasoline is stored. Do not overfill the fuel tank
(there should be no fuel in the filler neck). After refueling, make sure the tank cap is closed
properly and securely. Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may
ignite. If any fuel is spilled, make sure the area is dry before starting the engine. Avoid repeated
or prolonged contact with skin or breathing of vapor.
KEEP OUT OF REACH OF CHILDREN.
Fuel tank capacity: See specifications. (Page 21)
Use gasoline with a pump octane rating of 86 or higher. We recommend unleaded gasoline because it
produces fewer engine and spark plug deposits and extends exhaust system life. Never use stale or
contaminated gasoline or oil/gasoline mixture. Avoid getting dirt or water in the fuel tank. Occasionally
you may hear light knocking or pinging, (metallic rapping noise) while operating under heavy loads.
This is no cause for concern. If knocking or pinging occurs at a steady engine speed, under normal
load, change brands of gasoline. If knocking or pinging persists, contact your authorized QBP
generator dealer.
NOTICE
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 Limited Warranty does
not cover parts damaged by misuse.
Oxygenated Fuels
Some gasoline is being blended with alcohol or an ether compound to increase the octane. This
gasoline is collectively referred to as oxygenated fuels. Some areas of the United States use
oxygenated fuels to help meet clean air standards. If you use an oxygenated fuel, be sure its pump
octane rating is 86 or higher.
Ethanol (ethyl or grain alcohol)
