Checking and Filling Fuel

WARNING! To prevent serious injury from fire:

Fill the fuel tank in a well-ventilated area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it to cool before adding fuel.

Do not smoke.

1.Clean the Fuel Cap and the area around it.

2.Unscrew and remove the Fuel Cap.

3.If needed, fill the Fuel Tank to about 1 inch under the fill neck of the Fuel Tank with 87 octane or higher unleaded gasoline.

Note: Do not use gasoline containing more than 10% ethanol (E10). Do not use E85 ethanol.

Note: Do not use gasoline that has been stored in a metal fuel container or a dirty fuel container. It can cause particles to enter the carburetor, effecting engine performance and/or causing damage.

4.Then, replace the Fuel Cap.

5.Wipe up any spilled fuel and allow excess to evaporate before starting engine.

To prevent FIRE, do not start the engine while the smell of fuel hangs in the air.
