• The Zenoah engines are lubricated by oilspecially
formulated for air-cooled 2-stroke gasoline engine use.
If Zenoah oil is not available, use an anti-oxidant
added quality oil expressly labeled for air-cooled
2-stroke engine use (JASO FD GRADE OIL or ISO-L-
EGD GRADE).

• Theseenginesarecertiedto operateon unleaded
gasoline.
• Makesure to usegasoline 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.
• Poorquality gasolines or oils may damage sealing
rings, fuel lines or fuel tank of the engine.
■ HOW TO MIX FUEL
WARNING
• Payattentiontoagitation.
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 agita-
tion is necessary for the engine to last long. Be care-
ful that, if the agitation is insufficient, there is an in-
creased danger of early piston seizing due to abnor-
mally 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.
WARNING
1. Selectatandbaregroundforfueling.
2.Moveat least 10feet(3meters) away fromthe
fuelingpointbeforestartingtheengine.
3. Stoptheenginebeforerefuelingtheunit.Atthat
time,be sure tosufcientlyagitatethe mixed

■ 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-STROKE ENGINE USE – It can cause spark
plug fouling, exhaust port blocking, or piston ring
sticking.
4. Mixedfuelswhichhavebeenleftunusedforape-
riodofonemonthormore may clog the carbu retor
and result in the engine failing to operate properly.
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.
