associated with exhaust fume
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
inhalation, do not operate in
unventilated area. The exhaust
gases contain harmful carbon
monoxide.
2. To reduce the risk of hearing loss associated with
sound levels, hearing protection is required.
3. To reduce the risk of injury
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).)
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.
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.
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.
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.
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
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) Keep your body warm. Avoid using the blower

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)

sive pressure.
d) If you feel discomfort, redness and swelling of
your fingers or any other part of your body, see
a doctor before it gets worse.
g) Always store gasoline in a container approved for
flammable liquids.
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.
h) Make sure the unit is properly assembled and in
good operating condition.
i ) Do not use the blower near a fire,

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.

of hoses for many lawn and garden applications,
including areas such as gutters, screens, patios,
grills, porches and gardens.

identification to avoid mixing with raw gasoline or
other containers.
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 fuel-
ing 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 (2-
stroke water-cooling type)
mixed oil.
„
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.
•
RECOMMENDED MIXING RATIO
GASOLINE 50:OIL 1
FOR YOUR ENGINE LIFE, AVOID;
1. FUEL WITH NO OIL (RAW GASOLINE) - It will
cause severe damage to the internal engine parts
very quickly.
•
Exhaust emission are
controlled by the
fundamental engine
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.
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.
•
•
•
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.
•
•
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.
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.
„
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.

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.
•
[370BTS/BFS] [380BTS/BFS]
•
Never clean the paper filter by tapping on it. Doing so may break the element,
causing dust to get sucked into the blower and damaging the engine.

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 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 becom-
ing 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.
