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. If RedMax oil is not available, use an anti-oxidant added quality oil expressly labeled for air-cooled 2-cycle engine use. (JASO FC GRADE OIL or ISO EGC GRADE)

Do not use BIA or TCW (2-stroke water- cooling type) mixed oil.

Exhaust emission are controlled by the fundamental engine parameters and components(eq., carburation, ignition timing and port timing) without addition of any major hardware or the introduction of an inert material during combustion.

These engines are certified to operate on unleaded gasoline.

Make sure to use gasoline with a minimum octane number of 89 RON (USA/Canada: 87AL)

If you use a gasoline of a lower octane value than prescribed, there is a danger that the engine temperature may rise and an engine problem such as piston seizing may consequently occur.

Unleaded gasoline is recommended to reduce the contamination of the air for the sake of your health and the environment.

Poor quality gasolines or oils may damage sealing rings, fuel lines or fuel tank of the engine.

HOW TO MIX FUEL

IMPORTANT

Pay attention to agitation.

1.Measure out the quantities of gasoline and oil to be mixed.

2.Put some of the gasoline into a clean, approved fuel container.

3.Pour in all of the oil and agitate well.

4.Pour In the rest of gasoline and agitate
