WORKING CONDITION

1. Refrain from operating the blower
if you are tired, ill, or upset, or if
you are under the influence of al­cohol, drugs or medication.

2. To reduce the risk of hearing loss
associated with sound level(s),
hearing protection is required.

3. To reduce the risk of injury asso­ciated with thrown objects, al­ways wear eye protection and
foot protection. Eye protection
should meet the requirements of
ANSI Z87.1.

4. To reduce the risk of injury asso­ciated with the inhalation of dust,
use a face filter mask in dusty
conditions.

5. Wear sturdy rubber-soled shoes
or shoes with some other form of
anti-slip protection to help protect
you against falling.

6. To reduce the risk of injury asso­ciated with objects being drawn
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,

but do not squeeze the handles

doctor before getting worse.

8. The ignition system of your unit
produces an electromagnetic
field of a very low intensity. This
field may interfere with some
pacemakers. To reduce the risk
of serious or fatal injury, persons
with pacemaker should consult
their physician and the pace­maker manufacturer before oper­ating this tool.

WORKING CIRCUMSTANCE

1. To reduce the risk of injury asso­ciated with exhaust fume inhala­tion, do not operate in
unventilated area. The exhaust
gases contain harmful carbon
monoxide.

2. Avoid using the blower where
stable footing and balance are
not assured.

3. Never operate the machine in
high wind, bad weather, poten­tially explosive atmosphere, when
visibility is poor or in very high or
low temperatures. (Our recom­mended use environment is be­low 40 degrees C (104 degrees
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 sched-

ule, 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.

WARNING

To reduce the risk of fire and burn
injury:

a) Handle fuel with care. It is highly

flammable.
b) Do not smoke while handing fuel.
c) Do not refuel a hot engine.
d) Do not refuel a running engine.
e) Avoid spilling fuel or oil. Always

wipe unit dry before using.
f ) Move at least 10 ft. (3 meters)

away from the fueling point be-

fore starting engine.
g) Always store gasoline in a con-

tainer approved for flammable liq-

uids.
h) Make sure the unit is properly as-

sembled and in good operating

condition.
i ) Do not use the blower near a fire,

as aiming the blower in the direc-

tion of a flame may cause flam-

mable substances to ignite.

BEFORE STARTING THE
ENGINE

• Each time before starting the en-

gine, inspect the entire unit to see

if every part is in good order and

is securely tightened in place. If

any damage is found in the fuel

line, the exhaust line, or the igni-

tion wiring, do not use the blower

until it has been repaired.

IMPORTANT

• Before starting operation, al-

ways make sure to check if any

obstacles are left inside the

volute case and net. The ob-

stacles may cause damage on

fan and volute case and serious

injury.

7. Fuel

■ FUEL

• Gasoline is very flammable. Avoid smoking or bring-

ing 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 for-

mulated 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 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.

■ 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.

• As for details of quality assurance, read the descrip-

tion 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.

AIR CLEANER

• Check the air cleaner every 25 hours of use or more
frequently if used under dusty conditions. A clogged
air filter may increase fuel consumption while cutting
down the engine power. Never operate the blower
without the air filter or with a deformed filter element
because unfiltered dusty air may quickly ruin the en­gine.

CLEANING AIR FILTER:

1. Remove the air cleaner cover.

2. Use neutral detergent and warm water to clean the
filter element. After cleaning, air dry the element com­pletely.

3. Reinstall the filter. Never forget to attach the screen. If
the screen is not attached, the cleaner will not seal
properly and the dusts come into the cylinder.

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 (0.65mm).

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

REPLACEMENT PLUG IS NGK CMR7H.

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 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.

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.

• 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 two bolts. (Fastening
To rque : 7 to 11 N·m)

• Also make sure that the spark arrester and the dif­fuser are properly attached with two bolts. (Fastening
To rque : 2 to 3 N·m)

• Even if one of four bolts is loose, it may result in en­gine catching on fire.

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.

12. 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: 0.65 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
