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 conse-
quently 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 at least one minute. As some oils may be
difficult to agitate depending on oil ingredi-
ents, sufficient agitation is necessary for the
engine to last long. Be careful that, if the agi-
tation is insufficient, there is an increased
danger of early piston seizing due to abnor-
mally lean mixture.

5. Put a clear indication on the outside of the

container to avoid mixing up with gasoline or
other containers.

6. Indicate the contents on outside of container

for easy identification.

!

WARNING!

• 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 flat and 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.

• 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 block-
ing, 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 ren-
dering 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.

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.

STARTING ENGINE

Avoid operating the blower

with the flexible tube and swivel joint discon-
nected. That would cut down the engine cooling
air so that the engine could be damaged by over-
heat.

1. Push the primer bulb until fuel flows out in the

clear tube.

2. When the engine is cool, close the choke.

3. Set the stop switch(a) to the "I" position. Set

the throttle lever to the start position(1-2-3),
then start the engine following the procedure
described in 4.

4. To start, hold the top of the blower firmly with

your left hand. Pull the starter knob slowly
until you feel it engage and then give it a vig-
orous strong pull.

Avoid pulling the starter rope

out to its full extension. Do not allow the starter
rope to snap back. Rewind the rope slowly. This
will prevent premature damage to the starter.

5. Once the engine is running, gradually open

the choke if it was set closed, and let the
engine run at idle speed for a minute to warm
it up.

IMPORTANT

IMPORTANT

When the engine failed to

start after several attempts due to overchoking,
open the choke and repeat pulling the rope.

6. Pull the throttle lever to unlock it.

Make sure that the engine

has stopped and is cool before performing
any service to the blower. Contact with rotat-
ing blower fan or hot muffler may result in a
personal injury.

• CLEANING AIR FILTER:

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 ele-
ment because unfiltered dusty air may quickly
ruin the engine.

1. Remove the air cleaner cover by pulling the

tab on the bottom and take out the filter ele-
ment.

• 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). 

Plug manufacturers recommend replacing the
plug twice a year to avoid unexpected plug fail-
ure in a job.

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.

• MUFFLER

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.

Before starting operation, always make sure to
check if the muffler is properly held by three
bolts to the cylinder. (Fastening Torque: 8~12
Nm).
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.

!

WARNING!

IMPORTANT

• SPARK ARRESTER

The engine is equipped with a spark arresting
screen at the exhaust port. Periodically check
and keep it in good condition.  

• AIR INTAKE SCREEN (AIR INLET NET)

Blowing air is taken in from the air inlet net.
When air flow has dropped down during opera-
tion, 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.

Never use the blower with-

out the net of the blower. Before each use,
check that the net is attached in place and is
free from any damage.

Confirm that the catching screw on the air inlet
screen is not loose. if loose, tighten it.

• 

HANDLING THE THROTTLE CABLE
