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 as-
sociated with thrown objects, al-
ways 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 anti-slip protection to help
protect 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 vibra-
tions 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 white-
finger 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 fac-
tors. In order to reduce the risk
of whitefinger disease, the fol-
lowing 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,

of serious or fatal injury, per-
sons with pacemaker should
consult their physician and the
pacemaker manufacturer be-
fore operating this tool.
WORKING CIRCUMSTANCE
1. To reduce the risk of injury as-
sociated with exhaust fume in-
halation, do not operate in un-
ventilated 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, 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 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.
5. For safe operation
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

away from the fueling point be-
fore starting engine.
g) Always store gasoline in a con-
tainer approved for flammable
liquids.
h) Make sure the unit is properly
assembled and in good operat-
ing condition.
i) Do not use the blower near a
fire, as aiming the blower in the
direction of a flame may cause
flammable substances to ignite.
BEFORE STARTING THE
ENGIN
• Each time before starting the
engine, 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 ignition wiring, do not use
the blower until it has been re-
paired.
IMPORTANT
• Before starting operation, al-
ways make sure to check if
any obstacles are left inside
the volute case and net. The
obstacles may cause damage
on fan and volute case and
serious injury.

7. Fuel
■FUEL
W
ARNING
• 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-oxi-
dant added quality oil expressly labeled for air-
cooled 2-cycle engine use (JASO FD GRADE OIL
or ISO EGD GRADE).
• Do not use BIA or TCW (2-stroke water-cooling
type) mixed oil.
■RECOMMENDED MIXING RATIO GASO-
LINE 50 : OIL 1
<when using ZENOAH genuine oil>
• These engines are certified to operate on unleaded
gasoline.
• Make sure to use gasoline with a minimum octane
number of 90RON (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
W
ARNING
• 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.
7. Fuel
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 agi-
tation is necessary for the engine to last long. Be
careful that, if the agitation is insufficient, there is an
in- creased danger of early piston seizing due to ab-
normally lean mixture.
5. Indicate the contents on outside of container for
easy identification. To avoid mixing up the fuel 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.
W
ARNING
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 lubri-
cation.
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
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.
NOTE
• 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.

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 elec-
trodes as necessary with a wire brush. The spark
gap should be adjusted to .025 in (0.6~0.7mm).
• Plug manufacturers recommend replacing the plug
twice a year to avoid unexpected plug failure in a
job.
REPLACEMENT PLUG IS NGK CMR7H

9. Maintenance
IMPORTANT
• Note that using any spark plugs other than those
designated may result in the engine failing to oper-
ate 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
W
ARNING
• 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 en-
gine 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 dif-
fuser 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.
SPARK ARRESTER
• The muffler is equipped with a spark arrester to pre-
vent red hot carbon from flying out of the exhaust
outlet. Periodically inspect and clean as necessary
with a wire brush.
9. Maintenance
PROCEDURES TO BE PERFORMED AFTER
EVERY 100 HOURS OF USE
1. Remove the muffler, insert a screwdriver into the ex-
haust port, and wipe away any carbon buildup. Wipe
away any carbon buildup on the muffler exhaust
opening and cylinder exhaust port at the same time.
2. Tighten all screws, bolts, and fittings.
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 dam-
aged.
W
ARNING
Never use the blower without the net of the blow-
er. Before each use, check that the net is attached
in place and is free from any damage.

9. Maintenance
SHOULDER STRAP
If the shoulder strap is damaged it may break during
operation, thus causing the product to fall and resulting
in personal injury. Follow the instructions below to re-
place the shoulder strap with new one.
1. Take off the clip from the strap.
2. Pass the end of the strap through the eyelet.
3. Return the clip to the strap.
W
ARNING
• Make sure that the thick round bar of the clip is
in the strap.
If it is attached in the wrong way, it leads to se-
rious personal injury.
• Do not apply liquid type screw lock glue on
screws or bolts used to fix plastics components.
Adherence of this type of glue may cause cracks
on plastics and end up with the breakage.
10. Storage
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 cylinder. 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 disas-
semble the machine.
• When disposing your machine, fuel or oil for the ma-
chine, be sure to allow your local regulations.
