MIXING RATIO GASOLINE 50 : OIL 1

Exhaust emission are controlled by the fundamental en-
gine parameters and components (eq., carburation, igni-
tion timing and port timing) without addition of any ma-
jor hardware or the introduction of an inert material dur-
ing combustion.

• These engines are certified to operate on unleaded gaso-

line.

• 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 contami-

nation of the air for the sake of your health and the environ-
ment.

• 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 con-

tainer.

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 insuffi-
cient, 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 identi-

fication.

■ 

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.

■ 

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 plas-

tic 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 gaso-
line, etc. described therein, it may not be covered by the
warranty.

FUEL

Gasoline is very flammable. Avoid smoking or bringing
any flame or sparks near fuel. Make sure to stop the en-
gine 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 formu-

lated for air-cooled 2-cycle gasoline engine use. If Zenoah
oil is not available, use an anti-oxidant added quality oil ex-
pressly 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.
