AVOID NOISE PROBLEM
NOTE
Check and follow the local regulations as to sound
levels 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.
7. Prolonged use of a blower, exposing the operator to
vibrations and cold, may produce whitefinger
disease (Raynaud’s phenomenon), the symptoms of
which include 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
4. Check your equipment before operation, especially
the muffler, air intakes and air filters.
WORKING PLAN
-
To reduce the risk of health damages, avoid
excessive use and take sufficient time to rest.

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
carburetor and result in the engine failing to operate
properly.
5. When 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. When scrapping the used mixed oil container, scrap
it only at an authorized repository site.
-
Exhaust emission are
controlled by the
fundamental engine parameters and
components (i.e., 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 89 RON (USA/Canada: 87AL)
If you use a gasoline of a lower octane value than
specified, 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.
NOTE
-
-
For details of quality assurance, read the
description in the Warranty section carefully.
Moreover, normal wear and change in product
with no functional influence are not covered by
the warranty. Also, note that if the usage in the
instruction manual is not observed for the mixed
gasoline, etc. as described herein, it may not be
covered by the warranty.
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.
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.
Note that, if the agitation is insufficient, there is an
increased danger of early piston seizing due to an
abnormally lean mixture.
5. Indicate the contents on outside of container for
easy identification to avoid mixing with raw gasoline
or other containers.

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 vigorous
strong pull.
IMPORTANT
-
-
Never twist the starter cord around your hand.
Avoid pulling the starter rope out to its full extent and allowing the
starter rope to snap back.This will prevent premature damage to
the starter.
-
Do not let a person stand near the blower or the exhaust port.
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.
NOTE
When the engine fails to start after several attempts due to
overchoking, open the choke and repeat pulling the rope.
WARNING
Air comes out as soon as the engine is started, even at idle speed.

WARNING
Make sure that the engine has stopped and is cool before performing
any service to the blower. Contact with rotating blower fan or hot
muffler may result in a personal injury.

AIR CLEANER
-
Check the air cleaner before use.
A clogged air filter may increase fuel consumption while cutting down the engine power.
Never operate the blower without an air filter or with a deformed or broken filter element because unfiltered dusty
air will quickly ruin the engine.

NOTE
-
-
Do not apply 4 cycle motor oil as they may damage element.
Do not use mixture gasoline.This type of gasoline does not contain
much of oil, so that the element becomes dry after a few hours.
Soak the filter element into filter oil.
Squeeze the element to remove excess oil so that it weighs 2 to 3 times
heavier than it was dried.
-
-
4. Reinstall the element into the packing,set the packing into the air cleaner
body.
Never forget to attach the screen properly. If the screen is not attached, the
cleaner will not seal properly and the dusts come into the cylinder.
5. Reinstall the air cleaner cover and screw the 2 knobs.

FUEL FILTER
F18
-
A clogged fuel filter may cause poor acceleration of the engine. Check
periodically to see if the filter is 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
F19
-
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 to 0.7mm).
-
Plug manufacturers recommend replacing the plug twice a year to avoid
unexpected plug failure in a job.
REPLACEMENT PLUG IS A 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 with your hands until it is
tight, then tighten it a quarter turn more with a socket wrench.

WARNING
Periodically inspect the muffler for loose fasteners, damage or corrosion.
If any sign of exhaust leakage is found, do not use the blower and have it
repaired immediately.

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.

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.
(1) Bolt
(3) Spark Arrester
(2) Bolt
(4) Diffuser
WARNING
-
Before starting operation, always make sure to check if the muffler is
properly held by the bolts (2).
Fastening Torque: 8 to 12 N·m
Also make sure that the spark arrester and the diffuser are properly
attached with the bolts (1). (Fastening Torque : 2 to 3 N·m)

AIR INLET NET
F21
IMPORTANT
Blown air is taken in from the air inlet net. If the air flow drops during
operation, stop the engine and inspect the air inlet net for blockage by
obstacles.
(1)
-
Note that failure to remove any such obstacles may result in the engine
becoming overheated and damaged.
(1)Net
WARNING
Never use the blower without the net on the blower. Before each use,
check that the net is attached in place and is free from any damage.

SHOLDER STRAP
F23
-
If the shoulder strap is damaged it may break during use, thus causing the
product to fall and resulting in personal injury. Follow the instructions below to
replace the shoulder strap with new one.
-
-
-
Take off the clip from the strap.
Pass the end of the strap through the hanger.
Return the clip to the strap.
IMPORTANT
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 serious personal injury.
Storage
BEFORE STORING THE BLOWER:
1. Drain the 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 cylider. Crank the engine several time and install
the spark plug.
3. Store unit in a dry, cool and dark, well-ventilated, dust-free place, out of the reach of children.
