7. Fuel

■ 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-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 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.

1. Measure out the quantities of gasoline and oil to be
mixed.

GB-12

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.

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 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 pe-
riod 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.

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 instruction manual
is not observed as to the mixed gasoline, etc. de­scribed therein, it may not be covered by the war­ranty.

because unfiltered dusty air may quickly ruin the
engine.

CLEANING AIR FILTER:

1. Remove the air cleaner cover by pulling the tab on
bottom and take out the filter element.

FUEL FILTER

•A clogged fuel filter may cause poor acceleration of
the engine. Check periodically to see if the filter is
clogged with dirt. The filter can be taken out of the
fueling port using a small wire hook. Disconnect the
filter assembly from the fuel pipe and unhook the re­tainer to disassemble it. Clean the components with
gasoline.

10. Storage

WARNING

• When draining fuel, please be careful not to spill
it. If fuel is spilt, wipe off thoroughly. In addition,
please be sure to close the storage container cap
tightly.

IMPORTANT

• If fuel is left in the engine for protracted periods, the
inside of the carburetor may become clogged and
cause engine malfunction (faulty starting and insuffi­cient output).

• During storage, slightly loosen the cap of the chemi­cal fluid tank. If screwed too tightly, the gasket may
become distorted.

On completion of all work procedures, when not plan­ning to use again for a protracted period please carry
out the following pre-storage care, to prevent trouble
caused by time-lapse changes.

MD6210M

1. Clean the chemical fluid tank and nozzle.

2. Remove dirt from the sprayer, inspect it for any dam­age or looseness, and, if any abnormality is found,
correct it thoroughly in preparation for the next time
you use the unit.

3. Drain the fuel tank.

4. Start the engine, and leave it in idling condition until
all the fuel inside the carburetor is spent and the en­gine comes to a natural stop.

5. Remove the spark plug and put a few drops (1 to 2
cc) of 2-cycle oil inside the engine. After pulling the
starter rope 2 or 3 times, return the spark plugs to
their original position and stop in compressed posi­tion.
