into rotating parts, do not wear
loose clothing, scarves, neck
chains, hair longer than shoulder
length, or other loose material.

7. Prolonged use of a blower, expos­ing the operator to vibrations and
cold may produce whitefinger
disease (Raynaud’s phenom­enon), which symptoms are tin­gling and burning sensations fol­lowed by loss of color and numb­ness in the fingers. All factors
which contribute to whitefinger
disease are not known, but cold
weather, smoking diseases or
physical conditions as well as
long periods of exposure to vibra­tion are mentioned as factors. In
order to reduce the risk of
whitefinger disease, the following
precautions are strongly recom­mended;

a) Keep your body warm. Never use

blower during rains.

b) Wear thick anti-vibration gloves.
c) Take more than 5 minutes of break

in warm place frequently.

d) Maintain a firm grip at all times,

F).)

AVOID NOISE PROBLEM

IMPORTANT

Check and follow the local

regulations as to sound level
and hours of operations for
blower.

1. Operate power equipment only at
reasonable hours-not early in the
morning or late at night when
people might be disturbed. Com­ply with times listed in local ordi­nances.

2. To reduce sound levels, limit the
number of pieces of equipment
used at any one time.

3. Operate power blowers at the
lowest possible throttle speed to
do the job.

4. Check your equipment before op­eration, especially the muffler, air
intakes and air filters.

WORKING PLAN

• When planning your work sched­ule, allow plenty of time to rest.

Limit the amount of time over
which the product is to be used
continuously to somewhere
around 30 ~ 40 minutes per ses­sion, and take 10 ~ 20 minutes of
rest between work sessions. Also
try to keep the total amount of
work performed in a single day
under 2 hours or less.

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.

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.

■ 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) 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.

■ 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
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.

HB2302 / HBZ2602

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.

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).

MUFFLER

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. (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.

PROCEDURES TO BE PERFORMED AFTER EV­ERY 50 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.

•Plug manufacturers recommend replacing the plug
twice a year to avoid unexpected plug failure in a job.

REPLACEMENT PLUG

HB2302 : CHAMPION RCJ6Y (noise proof)
HBZ2602 : NGK CMR7H (noise proof)

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.

SPARK ARRESTER

• The engine is equipped with a spark arresting screen
at the exhaust port. Periodically check and keep it in
good condition. In the state of California it is required
by law (Section 4442 of the California Public Re­sources Code) to equip a spark arrester when a gas
powered tool is used in any forest covered, brush
covered, or grass covered unimproved land.

9. Maintenance 10. Storage

AIR INTAKE SCREEN (AIR INLET NET)

IMPORTANT

• Blowing air is taken in from the air inlet net. When air
flow has dropped down during operation, stop the
engine and inspect the air inlet net for blocking by
obstacles.

• Note that failure to remove any such obstacles may
result in the engine becoming overheated and dam­aged.

WARNING

• Never use the blower without the net of the blower.
Before each use, check that the net is attached in
place and is free from any damage.

BEFORE STORING THE BLOWER:

1. Drain a fuel tank and push the primer bulb until it be­comes empty of fuel.

2. Remove the spark plug and drop a spoonful of 2-cycle
oil into the cylider. Crank the engine several times and
install the spark plug.

3. Store unit in a dry, dust free place, out of the reach of
children.

11. Disposal

• When you dispose of the machine, do not disassemble
the machine.

• When disposing your machine, fuel or oil for the ma­chine, be sure to allow your local regulations.

13. Troubleshooting guide

Case 1. Starting failure

CHECK PROBABLE CAUSES ACTION

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
cylinder fin, fan cover → clogged with dust → clean
