flammable substances.
• Shut down the engine before adding fuel.
• Do not leave the machine when adding fuel or oil.
• Tighten all the fuel and oil caps securely.
• Be careful not to spill fuel on overheated surfaces or on
parts of the electrical system.
• After adding fuel or oil, wipe up any spilled fuel or oil.
• Put greasy rags and other combustible materials into a
safe container to maintain safety at the workplace.

not use diesel fuel or gasoline. There is danger that they
may catch fire.
