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 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-oxi-
dant added quality oil expressly labeled for air-
cooled 2-cycle engine use (JASO FD GRADE OIL
or ISO EGD GRADE).
• Do not use BIA or TCW (2-stroke water-cooling
type) mixed oil.
■ RECOMMENDED MIXING RATIO GASO-
LINE 50 : OIL 1
<when using ZENOAH genuine oil>
• These engines are certified to operate on unleaded
gasoline.
• Make sure to use gasoline with a minimum octane
number of 90RON (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.
7. Fuel
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
in- creased danger of early piston seizing due to ab-
normally lean mixture.
5. Indicate the contents on outside of container for
easy identification. To avoid mixing up the fuel 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 lubri-
cation.
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
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.
NOTE
• As for details of quality assurance, read the descrip-
tion in the section Limited Warranty carefully. More-
over, normal wear and change in product with no
