7. Fuel
■ FUEL
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 agi-
tate 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.
• 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.
G
B
■ 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 spill-
age around the unit.
• 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.
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.
■ FORYOUR 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.
■ 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 pre-
scribed, there is a danger that the engine tempera-
ture may rise and an engine problem such as piston
seizing may consequently occur.
6. In the case of scrapping the used mixed oil container,
scrap it only at an authorized repository site.
• 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.
• As for details of quality assurance, read the descrip-
tion in the section Limited Warranty carefully. More-
over, normal wear and change in product with no func-
tional 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. de-
scribed therein, it may not be covered by the warranty.
■ HOW TO MIX FUEL
• 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.

FUEL FILTER
MUFFLER
WARNING
• 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 re-
tainer to disassemble it. Clean the components with
gasoline.
• Inspect periodically, the muffler for loose fasteners,
any damage or corrosion. If any sign of exhaust leak-
age is found, do not use the blower and have it re-
paired immediately.
• Note that failing to do so may result in the engine
catching on fire.
IMPORTANT
• Before starting operation, always make sure to check
if the muffler is properly held by three bolts to the cyl-
inder. (Fastening Torque : 8~12 N·m)
• Even if one bolt out of three bolts is loose, the muffler
may get loose during operation which may result in
engine catching on fire.
SPARK PLUG
• The spark plug may gather carbon deposits on its
firing end with reasonable use. Remove and inspect
the spark plug every 25 hours and clean the elec-
trodes as necessary with a wire brush. The spark gap
should be adjusted to .025 in (0.6~0.7mm).
PROCEDURES TO BE PERFORMED AFTER EV-
ERY 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 cylin-
der exhaust port at the same time.
2. Tighten all screws, bolts, and fittings.
• Plug manufacturers recommend replacing the plug
twice a year to avoid unexpected plug failure in a job.
