FUEL
WARNING
•
Gasoline is very flammable. Avoid smo king 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-stroke gasoline engine use. If Zenoah
oil is not available, use an anti-oxidant added quality oil ex-
pressly labeled for air-cooled 2-stroke engine use (JASO FD
GRADE OIL or ISO-L-EGD 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>
(JASO FD GRADE OIL or ISO-L-EGD GRADE)
•
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 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
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 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 de-
pending on oil ingredients, sufficient agitation is neces-
sary for the engine to last long. Be careful that, if the agita-
tion is insufficient, 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 iden-
tification.
■
FUELING THE UNIT
1. Untwist and remove the fuel cap. Rest the cap on a dust-
less 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 con-
tainer.

FOR YOUR ENGINE LIFE, AVOID:
1. FUEL WITH NO OIL (RAW GASOLINE) – It will cause se-
vere 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.
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 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 in-
struction manual is not observed as to the mixed gasoline, etc.
described therein, it may not be covered by the warranty.

SUPPLYING CHAIN OIL
WARNING
Running the equipment for long hours with its chain oil run out
will accelerate the wear and tear of the chain and guide bar,
possibly resulting further in a chain cut and even in a fatal
accident leading to death.
1. For chain oil, use a type that is sufficiently viscous and
adequately lubricating under the summer-use conditions
and another type that shows similar performance under
the winter-use conditions.
2. The use of Zonoah genuine chain oil is recommended to
make your chain saws last as long as possible. If no genu-
ine chain oil is available, please use commercially avail-
able chain oil, which is commonly used.
CAUTION
Using waste oil, recycled oil, or anything similar causes a break-
down and also proves harmful to the human body and envi-
ronment. Please do not under any circumstances use any such
material.
IMPORTANT
Use chain oil of vegetable origin. Before storing it for a long
period, remove the chain oil from the blade and chain groove
and clean them. If not, the chain may become rusted. Chain
rust will cause the chain to become rigid or to become viscous
at the tip.
