5. FUEL

WARNING

•Gasoline is very flammable. Avoid smoking or bringing any flame or sparks near fuel.

•Wipe up all spills before starting the engine.

•Make sure to stop the engine and allow it cool before refueling the unit.

•Keep open flames away from the area where fuel is handled or stored.

IMPORTANT

•Never use oil for 4 cycle engine use or water cooled 2-cycle engine. It can cause spark plug fouling, exhaust port blocking, or piston ring sticking.

•Mixed fuels which have been left unused for a period of one month or more may clog the carburetor or result in the engine failing to operate properly. Put remained fuel into an air-tight container and keep it in the dark and cool room.

Mix a regular grade gasoline (leaded or unleaded, alcohol-free) and a quality-proven motor oil for air cooled 2 cycle engines.
