7. Fuel
EBZ4800 / EB7000
■ 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 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.
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 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. 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.
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.

■ RECOMMENDED MIXING RATIO
GASOLINE 50 : OIL 1
<when using ZENOAH genuine oil>
• Exhaust emission are controlled by the fundamental 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 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 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
IMPORTANT
• Pay attention to agitation.
■ 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 carburetor 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.
• 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.
