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 refuel-
ing the unit. Select outdoor bare ground for fuel-
ing and move at least 3 m (10 ft) away from the
fueling point before starting the engine.

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
increased danger of early piston seizing due to ab-
normally 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

identification.

■

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 flat and 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 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.

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 con-

tainer, 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, nor-
mal wear and change in product with no functional in-
fluence are not covered by the warranty. Also, be care-
ful that, if the usage in the instruction manual is not ob-
served as to the mixed gasoline, etc. described therein,
it may not be covered by the warranty.

CHAIN OIL

Use motor oil SAE #10W-30 all year round or SAE
#30 ~ #40 in summer and SAE #20 in winter.

NOTE

Do not use wasted or regenerated oil that can cause
damage to the oil pump.

• 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) with-
out addition of any major hardware or the intro-
duction 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 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.
