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. 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)

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 90 ROZ(USA/Canada : pump octane min.87)

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

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 again for at least one minute.

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.

FUELING THE UNIT

1.Untwist and remove the fuel cap. Rest the cap on a dustless place.

2.Put fuel into the fuel tank to 80% of the full capacity.

3.Fasten the fuel cap securely and wipe up any fuel spillage around the unit.

WARNING

1.Select bare ground for fueling.

2.Move at least 10 feet (3 meters) away from the fueling point before starting the engine.

3.Stop the engine before refueling the unit.

FOR YOUR ENGINE LIFE, AVOID;

1.FUEL WITH NO OIL(RAW GASOLINE) – It will cause severe damage to the internal engine parts very quickly.

2.GASOHOL – It can cause deterioration of rubber and/or plastic parts and disruption of engine lubrication.

3.OIL FOR 4-CYCLE ENGINE USE or

WATER COOLED 2-CYCLE ENGINE USE – It can cause spark plug fouling, exhaust port blocking, or piston ring sticking.

4.Mixed fuels which have been left unused for a period of one month or more may clog the carburetor and result in the engine failing to operate properly.
