7. Fuel
■ FUEL
• 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.
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.
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
period 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.
• 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.

WARNING
Make sure that the engine has stopped and
is cool before performing any service to the
blower. Contact with rotating blower fan or
hot muffler may result in a personal injury.
AIR CLEANER
• Never operate the blower without the air filter or with
a deformed filter element because unfiltered dusty
air will quickly ruin the engine.
• Check the air cleaner before use.
A clogged air filter may increase fuel consumption
while cutting down the engine power.
[EB7000]
• Never clean a paper filter by striking it with or against
another object. The filter may be damaged and resultant dust contamination can diminish engine performance.
CLEANING AIR FILTER:
[EBZ4800]
1. Remove the air cleaner cover by pulling the tab on
bottom and take out the filter element.
2. Use neutral deterget and warm water to clean the
filter element. After cleaning, air dry the element completely and moisten with a samll amount of 2 cycle
motor oil.
(1) 2 Cycle Motor Oil
NOTE
Soak the filter element into a 2cycle motor oil. Suqueeze
the element to remove excess oil so that it weighs 2 to 3
times heavier than that of the dry element.
3. Place the filter element into the packing with the yellow side facing to the cover. Set the packing into the

NOTE
• Assure that the screen is securely fitted to the packing. Fit securely if it is loose.
• Insufficient fixing of screws may cause fall off of the
cover and insufficient sealing.
• Care shall be taken to an direction of the filter element. Incorrect direction of the element will result in
poor element performance.
NOTE
• Do not apply 4 cycle motor oils as they may damage
element.
• Do not use mixture gasoline. this type of gasoline
does not contain much of oil so that element becomes
dry after a few hours.
IMPORTANT
Place the filter element into the packing with the yellow
side facing to the cover. Set the packing into the air
cleaner body. Set the cover with 2 fixing screws.

IMPORTANT
• Note that using any spark plugs 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.
MUFFLER
2. Wash the prefilter in fresh, non flammable cleaning solution (ex. warm soapy water) and then dry.
(Clean the air filter once in a week.)
3. Exchange the paper filter element with new one in case it
has been contaminated.
WARNING
• This prefilter is dry type.
• Never wash the prefilter in oleaginous cleaning solution.
• Do not clean a paper filter by striking it.
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.
(1) Screen
(3) Holder
WARNING
• Inspect periodically, the muffler for loose fasteners,
any damage or corrosion. If any sign of exhaust leakage is found, do not use the blower and have it repaired 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 cylinder and crank case. (Fastening Torque : 8~12 N·m)
• Also make sure that the spark arrester and the diffuser are properly attached with four bolts (Fastening
Torque : 2~3 N·m)
• Even if one of seven bolts is loose, it may result in
engine catching on fire.

(4) Retainer
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 electrodes as necessary with a wire brush. The spark gap
should be adjusted to .025 in (0.6~0.7mm).
(1) Bolt
(2) Spark Arrester
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. In the State of California it is required by
law (Section 4442 of the California Pulic Resources
Code) to equip a spark arrester when a gas powered
tool is used in any forest covered, bush covered, or
grass covered unimproved land.
NOTE
• Plug manufacturers recommend replacing the plug
twice a year to avoid unexpected plug failure in a job.

9. Maintenance
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.
HARNESS
If the harness is damaged it may break during use, thus
causing the product to fall and resulting in personal injury. Follow the instructions below to replace the harness
