■ 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
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. 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 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.
GASOHOL – It can cause deterioration of rubber and/
2.
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.
G
B
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.

WARNING
Make sure that the engine has stopped and is cool
before performing any service to the machine. Contact with moving cutting head or hot muffler may result in a personal injury.
AIR FILTER
• The air filter, if clogged, will reduce the engine performance. Check and clean the filter element in warm,
soapy water as required. Dry completely before installing. If the element is broken or shrunk, replace
with a new one.
Air Filter
FUEL FILTER
• When the engine runs short of fuel supply, check the
fuel cap and the fuel filter for blockage.s
IMPORTANT
• Note that using any spark plug other than those designated may result in the engine failing to operate
properly or in the engine becoming overheated and
damaged.
•To install the spark plug, first turn the plug until it is
finger tight, then tighten it a quarter turn more with a
socket wrench.
TIGHTENING TORQUE:
MUFFLER
WARNING
• Inspect periodically, the muffler for loose fasteners, any damage or corrosion. If any sign of exhaust leakage is found, stop using the machine
and have it repaired immediately.
• Note that failing to do so may result in the engine
catching on fire.
SPARK ARRESTER
• The muffler is equipped with a spark arrester to prevent red hot carbon from flying out of the exhaust outlet. Periodically inspect and clean as necessary with
a wire brush.

INTAKE AIR COOLING VENT
WARNING
•Never touch the cylinder, muffler, or spark plugs
with your bare hands immediately after stopping
the engine. The engine can become very hot when
in operation, and doing so could result in severe
burns.
• When checking the machine to make sure that it
is okay before using it, check the area around the
muffler and remove any wood chips or leaves
which have attached themselves to the machine.
Failing to do so could cause the muffler to become
overheated, and that this in turn could cause the
engine to catch on fire. Always make sure that the
muffler is clean and free of wood chips, leaves,
and other waste before use.
• Check the intake air cooling vent and the area
around the cylinder cooling fins after every 25
hours of use for blockage, and remove any waste
which has attached itself to the machine. Note that
it is necessary to remove the engine cover shown
in (A) in order to be able to view the upper part of
the cylinder.
IMPORTANT
• If waste gets stuck and causes blockage around the
intake air cooling vent or between the cylinder fins, it
may cause the engine to overheat, and that in turn
may cause mechanical failure on the part of the machine.
Cylinder
PROCEDURES TO BE PERFORMED AFTER EVERY 100 HOURS OF USE
1. Remove the muffler, insert a screwdriver into the vent,
and wipe away any carbon buildup. Wipe away any
carbon buildup on the muffler exhaust vent and cylinder exhaust port at the same time.
2. Tighten all screws, bolts, and fittings.
3. Check to see if any oil or grease has worked its way
in between the clutch lining and drum, and if it has
wipe it away using oil-free, lead-free gasoline.
10. Storage
• Aged fuel is one of major causes of engine starting
failure. Before storing the unit, empty the fuel tank and
run the engine until it uses all the fuel left in the fuel
line and the carburetor. Store the unit indoor taking
necessary measures for rust prevention.
• Oil the blades.
11. Disposal

fuel tank → incorrect fuel → drain it and use correct fuel
fuel filter → fuel filter is clogged → clean
carburetor adjustment screw → out of normal range → adjust to normal range
sparking (no spark) → spark plug is fouled/wet → clean/dry
→ plug gap is incorrect → correct (GAP: 0.6 ~ 0.7 mm)
spark plug → disconnected → retighten
Case 2. Engine starts but does not keep running/hard re-starting
CHECK PROBABLE CAUSES ACTION
fuel tank → incorrect fuel or staled fuel → drain it and use correct fuel
carburetor adjustment screw → out of normal range → adjust to normal range
muffler, cylinder (exhaust port) → carbon is built-up → wipe away
air cleaner → clogged with dust → wash
