Introduction
DEAR CUSTOMER!
Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when
the Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production of muskets.
The location was logical, since water power was harnessed from the Huskvarna River to create the water-powered plant. During
over 300 years of continuous operation, the Husqvarna factory has produced a lot of different products, from wood stoves to
modern kitchen appliances, sewing machines, bicycles, motorcycles etc. In 1956, the first motor driven lawn mowers appeared,
followed by chain saws in 1959, and it is within this area Husqvarna is working today.
Today Husqvarna is one of the leading manufacturers in the world of forest and garden products, with quality as our highest
priority. We develop, manufacture and market high quality motor driven products for forestry and gardening as well as for
building and construction industry.
Your purchase gives you access to professional help with repairs and service whenever this may be necessary. If the retailer who
sells your machine is not one of our authorized dealers, ask for the address of your nearest servicing dealer.
It is our wish that you will be satisfied with your product and that it will be your companion for a long time. Think of this
operator's manual as a valuable document. By following its' content (using, service, maintenance etc) the life span and the
second-hand value of the machine can be extended. If you ever lend or sell this machine, make sure that the borrower or buyer
gets the operator's manual, so they will also know how to properly maintain and use it.
Thank you for using a Husqvarna product.
Husqvarna AB has a policy of continuous product development and therefore reserves the right to modify the design and
appearance of products without prior notice.

HANDLING FUEL
1. The engine of the Husqvarna product is designed to
run on a mixed fuel, which contains highly flammable
gasoline. Never store cans of fuel or refill the tank of the
unit in any place where there is a boiler, stove, wood fire,
electrical sparks, welding sparks, or any other source of
heat or fire which might ignite the fuel.
2. Never smoke while operating the unit or refilling its fuel
tank.
3. When refilling the tank, always turn off the engine and
allow it to cool down. Take a careful look around to make
sure that there are no sparks or open flames anywhere
nearby before refueling.
4. Wipe spilled fuel completely using a dry rag if any fuel
spillage occurs during refueling.
5. After refueling, screw the fuel cap back tightly onto the
fuel tank and then carry the unit to a spot 3 m or more
away from where it was refueled before turning on the
engine.
6. Do not inhale fuel fumes as they are toxic.
TRANSPORTATION
1. When hand-carrying the product, cover over the cutting
part if necessary, lift up the product and carry it paying
attention to the blade.
2. Never transport the product over rough roads over long
distances by vehicle without removing all fuel from
the fuel tank. If doing so, fuel might leak from the tank
during transport.

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 3m
(10ft) away from the fueling point before starting the
engine.
• The Husqvarna engines are lubricated by oil specially
formulated for air-cooled 2-cycle gasoline engine use. If
Husqvarna oil is not available, use an antioxidant added
quality oil expressly labeled for aircooled 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.

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. Be careful that, if
the agitation is insufficient, there is an increased danger
of early piston seizing due to abnormal lean mixture.
5. Put a clear indication on the outside of the container to
avoid mixing up with other containers.
6. Indicate the contents on outside of container for easy
identification.
FUELING THE UNIT
1. Untwist and remove the fuel cap. Keep the cap and inlet
of the tank clean.
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 10feet (3meters) away from the fueling
point before starting the engine.
Stop the engine before refueling the unit. At that time, be sure
3.
to sufficiently agitate the mixed gasoline in the container.
• Exhaust emission are controlled by the fundamental
engine parameters and components(eq., 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
prescribed, 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.
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. 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 description in
the section Limited Warranty carefully. 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.

W ARNING
Always follow the safety precautions.
The hedge-trimmer must only be used to trim hedges
or small bushes. It is forbidden to cut other types of
material. Do not use the hedge-trimmer as a lever to lift,
move or break objects, nor lock it on fixed supports. It is
forbidden to apply tools or applications that are not the
ones indicated by the manufacturer onto the hedgetrimmer’s power take-off. Do not use it for pruning trees
or cutting grass.
• Use only as much throttle as is needed to do the job.
Excessive engine speed is unnecessary.
• Avoid cutting thick branches, for which will damage the
blades and shorten the life of drive systems.
• Always keep your body to the carburetor side of your
trimmer, never on the muffler side.
• When a new machine is first operated, in the first few
minutes grease may come out of the gear case. But, since
this is excess grease, there is no cause for alarm. Just wipe
it off with the engine stopped for next use.
• Always remember that the TIP of the line does cutting.
You will achieve better results by not crowding the line
into the cutting area. Allow the unit to trim at its own
pace.

W ARNING
Make sure that the engine has stopped and is cool before performing any service to the machine. Contact with moving cutting
head or hot muffler may result in a personal injury.
AIR FILTER
• The air filter, if clogged, will reduce the engine
performance. Check and clean the filter element in warm,
soapy water as required. Dry completely before installing.
If the element is broken or shrunk, replace with a new
one.

FUEL FILTER
• When the engine runs short of fuel supply, check the fuel
cap and the fuel filter for blockage.
SPARK PLUG
• Starting failure and mis-firing are often caused by a
fouled spark plug. Clean the spark plug and check that
the plug gap is in the correct range. For a replacement
plug, use the correct type specified by Husqvarna.

IMPORTANT
• Note that using any spark plug 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

INTAKE AIR COOLING VENT
W ARNING
• Never touch the cylinder, muffler, or spark plugs with
your bare hands immediately after stopping the engine.
The engine can become very hot when in operation, and
doing so could result in severe burns.
• Clean the cylinder fins with compressed air or a brush.
IMPORTANT
If waste gets stuck and causes blockage around the
intake air cooling vent or between the cylinder fins,
it may cause the engine to overheat, and that in turn
may cause mechanical failure on the part of the hedgetrimmer.
Check the cutting edges and reform with a flat file.
Point :
1. Keep the end corner sharp.
2. Round the root of the edge.
3. Do not use water when using a grinder.
IMPORTANT
• When mounting the blade, make sure to fasten the
spacer, washer and bolt, then fasten the nut.

BLADES
Oil blades each gas tank filling.
W ARNING
• Make sure that the blade bolts are well tightened.
• The blade assembly is designed to automatically
compensate for any play between the blades.
SHARPENING
Always keep the file or sharpener at an angle of 45° to the
blade, and:
• Always grind in the direction of the cutting edge;
• Note: files cut only in one direction; lift the file from the
blade when returning to start a new pass;
• Remove all burr from the edge of the blade with a slip
stone;
• Remove as little material as possible;
• Before refitting the sharpened blades, remove filings
and then apply grease.
Do not try to sharpen a damaged blade: change it or take it
to a Service dealer.
