set, or if you are under the influ-
ence of alcohol, drugs or medi-
cation.
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

shoes with some other form of
anti-slip protection to help pro-
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, unconfined long
hair, and the like.
7.Prolonged use of a blower, ex-
posing the operator to vibrations
and cold may produce
whitefinger disease (Raynaud’s
phenomenon), which symptoms
are tingling and burning sensa-tions followed by loss of color
and numbness in the fingers. All
factors which contribute to
whitefinger disease are not
known, but cold weather, smok-
ing diseases or physical condi-
tions as well as long periods of
exposure to vibration are men-
tioned as factors. In order to re-
duce the risk of whitefinger dis-
ease, 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
with constant, excessive pres-
sures.
e)If you feel discomfort, redness
and swelling of your fingers or
any other part of your body, see
a 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 pace-
maker manufacturer before op-
erating this tool.
WORKING CIRCUMSTANCE
1. To reduce the risk of injury asso-
ciated with exhaust fume inhala-
tion, 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.

■ RECOMMENDED MIXING RATIO
    GASOLINE 50 : OIL 1
•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
prescribed, there is a danger that the engine tem-
perature 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
•    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 atleast one minute. As some oils may be difficult to
agitate depending on oil ingredients, sufficient agi-
tation 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 ab-
normally lean mixture.
5.Put a clear indication on the outside of the container
to avoid mixing up with gasoline or other contain-
ers.
6.Indicate the contents on outside of container for easy
identification.
■ 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 fuel-
ing 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.
■ 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 con-
tainer, scrap it only at an authorized repository site.
•    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
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.
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 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.
• The Komatsu Zenoah engines are lubricated by oil
specially formulated for air-cooled 2-cycle gasoline
engine use. If Komatsu 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.
