WORKING CONDITION
1. Refrain from operating the blow-
er 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 as-
sociated 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 as-
sociated 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

tect you against falling.
6. To reduce the risk of injury as-
sociated 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, ex-
posing the operator to vibrations
and cold may produce whitefin-
ger disease (Raynaud’s phenom-
enon), which symptoms are tin-
gling and burning sensations
followed by loss of color and
numbness in the fingers. All fac-
tors which contribute to whitefin-
ger disease are not known, but
cold weather, smoking diseases
or physical conditions as well as
long periods of exposure to vi-
bration are mentioned as factors.
In order to reduce the risk of
whitefinger disease, the follow-
ing 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,

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 pace-
maker manufacturer before op-
erating this tool.
WORKING CIRCUMSTANCE
1. To reduce the risk of injury as-
sociated with exhaust fume inha-
lation, do not operate in unventi-
lated area. The exhaust gases
contain harmful carbon monox-
ide.
2. Avoid using the blower where
stable footing and balance are
not assured.
3. Never operate the machine in
high wind, bad weather, poten-
tially explosive atmosphere,
when visibility is poor or in very
high or low temperatures. (Our
recommended use environment
is below 40 degrees C (104 de-
grees 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

ply with times listed in local ordi-
nances.
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

■FUEL
WARNING
• Gasoline is very flammable.Avoid smoking 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)

■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certied tooperateonunleaded

■HOW TO MIX FUEL
WARNING
• 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 agita-
tion is necessary for the engine to last long. Be care-
ful that, if the agitation is insufficient, there is an in-
creased danger of early piston seizing due to abnor-
mally 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.
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 sufciently 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 carbu-
retor and result in the engine failing to operate prop-
erly.
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.

SPARK ARRESTER
• The mufer 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 re-
quired 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 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
cylinder exhaust port at the same time.
2. Tighten all screws, bolts, and fittings.
