STARTING THE ENGINE
1. Keep bystanders and animals at
least 15 m away from the operat-
ing point. If you are approached,
immediately stop the engine.
2. The product is equipped with a
centrifugal clutch mechanism, so
the cutting attachment begins to
rotate as soon as the engine is
started by putting the throttle trig-
ger into the start position. When
starting the engine, place the
product onto the ground in a flat
clear area and hold it firmly in
place so as to ensure that neither
the cutting part nor the throttle
trigger come into contact with any
obstacle when the engine starts.
WARNING
Never place the throttle trigger
into the high-speed position when
starting the engine.
3. After starting the engine, check
to make sure that the cutting at-
tachment stops rotating when the
throttle is moved fully back to its
original position. If it continues to
rotate even after the throttle trig-
ger has been moved fully back,
turn off the engine and take the
unit to your authorized ZENOAH
servicing dealer for repair.

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 refuel-
ing 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 en-
gine 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 introduc-
tion 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 pre-
scribed, there is a danger that the engine tempera-
ture 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
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
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 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 fu-
eling point before starting the engine.
3. Stop the engine before refueling the unit. At that
time, be sure to sufficiently agitate the mixed gaso-
line 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 stick-
ing.
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, nor-
mal wear and change in product with no functional influ-
ence 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.
