4. Fuel and Chain Oil

■FUEL

•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 refuel- ing the unit. Select outdoor bare ground for fuel- ing and move at least 3 m (10 ft) away from the fueling point before starting the engine.

•The Komatsu Zenoah engines are lubricated by oil specially formulated for air-cooled 2-cycle gasoline engine use. If Komatsu Zenoah 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.

■RECOMMENDED MIXING RATIO GASOLINE 50 : OIL 1

(when using ZENOAH genuine oil)

•Exhaust emission are controlled by the funda- mental engine parameters and components (eq., carburation, ignition timing and port timing) with- out addition of any major hardware or the intro- duction 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 89RON (USA/Canada: 87AL).

•If you use a gasoline of a lower octane value than prescribed, there is a danger that the engine tem- perature 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

• 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 again for at least one minute. As some oils may be difficult to agitate depending on oil ingredients, sufficient agi- tation 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 ab- normally lean mixture.

5.Put a clear indication on the outside of the container to avoid mixing up with gasoline or other contain- ers.

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.

1.Select bare ground for fueling.

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

3.Stop the engine before refueling the unit. At that time, be sure to sufficiently agitate the mixed gasoline in the container.

■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 – 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 carbu- retor and result in the engine failing to operate prop- erly.

5.In the case of storing the product for a long period of time, clean the fuel tank after rendering it empty. Next, activate the engine and empty the carburetor of the composite fuel.

6.In the case of scrapping the used mixed oil con- tainer, scrap it only at an authorized repository site.

Note: As for details of quality assurance, read the description in the section Limited Warranty carefully. Moreover, normal wear and change in product with no functional influence are not covered by the warranty. Also, be careful that, if the usage in the instruction manual is not observed as to the mixed gasoline, etc. described therein, it may not be covered by the warranty.

■CHAIN OIL

Use motor oil SAE #10W-30 all year round or SAE #30 ~ #40 in summer and SAE #20 in winter.

Note: Do not use wasted or regenerated oil that can cause damage to the oil pump.
