FUEL
WARNING
• Gasoline is very flammable. Avoid smo king 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 3 m (10 ft) away from the fueling point
before starting the engine.
• 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.
■
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) without
addition of any major hardware or the introduction
of an inert material during com bustion.
• 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
WARNING
• 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 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. Indicate the contents on outside of container for easy
identification. To avoid mixing up with gasoline or
other containers.
■
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. At that
time, be sure to sufficiently agitate the mixed
gasoline in the container.
4. Do not smoke or place hot object near fuel.
■
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 container,
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.
