Fuel WARNING • Gasoline is very flammable. Avoid smoking or bringing any flame or sparks near fuel. Make sure to stop the engine and allow it cool before refueling the unit. Select outdoor bare ground for fueling and move at least 3m (10ft) away from the fueling point before starting the engine. • The RedMax engines are lubricated by oil specially formulated for air-cooled 2-cycle gasoline engine use.
Fuel again for at least one minute. As some oils may be difficult to agitate depending on oil ingredients, sufficient agitation is necessary for the engine to last long. Be careful that, if the agitation is insufficient, there is an increased danger of early piston seizing due to abnormally lean mixture. 5. Put a clear indication on the outside of the container to avoid mixing up with gasoline or other containers. 6. Indicate the contents on outside of container for easy identification.
