• The Zenoah engines are lubricated by oil

specially formulated for air-cooled 2-cycle
gasoline engine use. If 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.

• 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

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

■ STARTING ENGINE

1. Feed fuel into the fuel tank and tighten the

cap securely.

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. 

■ 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.

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.

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

container, scrap it only at an authorized
repository site.
