Safety Precautions
WORKING CONDITIONS
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 levels, hearing protection is required.
3. To reduce the risk of injury
associated with thrown objects,
always wear eye protection and
foot protection. Approved
protective goggles must comply
with standard ANSI Z87.1 in the
USA or EN 166 in EU countries.
4. To reduce the risk of injury
associated with the inhalation of
dust, use a face filter mask in dusty
conditions.
5. Wear 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
associated 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, 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
a) Keep your body warm. Avoid using the blower
during rain.
b) Take more than 5 minutes of
break in a warm place frequently.
c) Maintain a firm grip at all
times, but do not squeeze the
handles with constant, excessive pressure.
d) If you feel discomfort, red-
ness and swelling of your fingers or any other
part of your body, see a doctor before it gets
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, people with
pacemaker should consult their physician and the
pacemaker manufacturer before operating this tool.
WORKING CIRCUMSTANCE
1. To reduce the risk of injury
associated with exhaust fume
inhalation, 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.
3. Never operate the machine in high wind, bad
weather, potentially explosive atmosphere, when
visibility is poor or in very high or low temperatures.
(Our recommended use environment is below 40
degrees C (104 degrees F).)
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.
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.
FUEL
WARNING
To reduce the risk of fire and burn injury:
a) Handle fuel with care. It is
highly flammable.
b) Do not smoke while handing
fuel.
c) Do not refuel a hot engine.
d) Do not refuel a running engine.
e) Avoid spilling fuel or oil. Always
wipe unit dry before using.
f ) Move at least 10 ft. (3 meters) away from the
fueling point before starting the engine.
g) Always store gasoline in a container approved
for flammable liquids.
h) Make sure the unit is properly assembled and in
good operating condition.
i ) Do not use the blower near a

vibration occurs, stop the engine immediately and
contact the nearest Husqvarna servicing dealer
for assistance. Checking the fan is very important.
If the rotating fan should break up, it might lead to
serious accidents.
1. Check the work area that the blower will be used in
and remove or cover all valuables that may be
damaged by the air blast or thrown debris.
2. To reduce the risk of injury associated with thrown
objects.
a) Watch out for children, pets, open windows or
freshly washed cars, and blow debris safely
away.

blown onto someone else’s property.
f) Pay attention to the direction of the wind, do not
work against the wind.
3. To minimize blowing time.
a) Use rakes and brooms to loosen debris before
blowing.
b) In dusty conditions, slightly dampen surfaces or
use a mister attachment when water is available.
c) Conserve water by using power blowers instead
of hoses for many lawn and garden
applications, including areas such as gutters,
screens, patios, grills, porches and gardens .
4. The blower must not be used
while on a ladder or scaffolding.
5. Never put the machine down with
the engine running unless you

FUEL
WARNING
- 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
10ft (3m) away from the
fueling point before
starting the engine.
- The engines are lubricated
by oil specially formulated
for air-cooled 2-cycle
gasoline engine use. If
Husqvarna 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 (2stroke water-cooling type)
mixed oil.
RECOMMENDED MIXING RATIO
GASOLINE 50:OIL 1
- 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.
- 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.
Fuel
FUELING THE UNIT
1. Untwist and remove the fuel cap.
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 and let it cool for a few
minutes 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 objects 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
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.
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

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.

air will quickly ruin the engine.
CLEANING AIR FILTER:
1. Unscrew the 2 knobs and remove the air cleaner cover.
(1) Knob (2) Element
(3) Screen (4) Packing
2. Wash the filter element with neutral detergent and warm water and then dry
completely.
(Clean the air filter once in the week.)
3. Moisten the filter element with a small amount of filter oil.
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
- 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.
