product.
• You must understand the difference between grass
clearing and grass trimming before use.
• If you encounter a situation where you are uncertain
how to proceed you should ask an expert. Contact
your dealer or your service workshop. Avoid all
usage which you consider to be beyond your
capability.
• Never use a product that is faulty. Carry out the
safety checks, maintenance and service instructions
described in this manual. Some maintenance and
service measures must be carried out by trained and
qualified specialists. Refer to

• Never use the product if you are fatigued, while
under the influence of alcohol or drugs, medication
or anything that could affect your vision, alertness,
coordination or judgement.
• Do not use the product in bad weather such
as dense fog, heavy rain, strong wind, intense
cold, etcetera. Working in bad weather is tiring
and often brings added risks, such as icy ground,
unpredictable felling direction, etcetera.
• The only accessories you can operate with this
engine unit are the cutting attachments that we
recommend in the chapter
Accessories on page 24 .
1999 - 001 - 14.06.2023 5

• Never allow children to use or be in the vicinity of the
product. As the product is equipped with a spring-
loaded start/stop switch and can be started by low
speed and force on the starter handle, even small
children under some circumstances can produce the
force necessary to start the product. This can mean
a risk of serious personal injury. Therefore remove
the spark plug cap when the product is not under
close supervision.
• Running an engine in a confined or badly ventilated
area can result in death due to asphyxiation or
carbon monoxide poisoning.
• The complete clutch cover and shaft must be fitted
before the product is started, otherwise the clutch
can come loose and cause personal injury.
• Ensure that no people or animals come closer than
15 meters while you work. When several operators
are working in the same area the safety distance
should be at least 15 meters. Otherwise there is
a risk of serious personal injury. Stop the product
immediately if anyone approaches. Never swing the
product around without first checking behind you to
make sure that no one is within the safety zone.
• Ensure that people, animals or other things can
not affect your control of the product or that they
do not come in contact with the cutting attachment
or loose objects that are thrown out by the cutting
attachment. However, do not the product unless you
are able to call for help in the event of an accident.
• Always inspect the working area. Avoid all loose
objects such as stones, broken glass, nails, steel
wire, string, etcetera, that could be thrown out or
become wrapped around the cutting attachment.
• Make sure that you can move and stand safely.
Check the area around you for possible obstacles
(roots, rocks, branches, ditches, etcetera) in case
you have to move suddenly. Take great care when
you work on sloping ground.
• Keep a good balance and a firm foothold at all times.
Do not overreach.
• Always hold the product with both hands. Hold the
product on the right side of your body.
• Use the harness and make sure that you attach it
to the suspension ring.
• Keep the cutting attachment below waist level.
• Switch off the engine before you move to an other
area. Install the transportation guard before you
carry or transport the equipment any distance.
• Never put the product down with the engine running
unless you have it in clear sight.
• Stop the engine and cutting equipment before you
remove material that has wound around the blade
shaft. Neither the operator of the product nor anyone
else may attempt to remove the cut material while
the engine is running or the cutting equipment is
rotating, as this can result in serious injury. The
bevel gear can get hot during use and may remain
so for a while afterwards. You could get burnt if you
touch it.
• Watch out for thrown objects. Always wear
approved eye protection. Never lean over the cutting
attachment guard. Stones, rubbish, etcetera, can be
thrown up into the eyes which can cause blindness
or serious injury.
• Sometimes branches or grass get caught between
the guard and cutting attachment. Always stop the
engine before you clean the product.
• Products that are fitted with saw blades or grass
blades can be thrown violently to the side when
the blade comes into contact with a fixed object.
This is called blade thrust. A blade thrust can be
violent enough to cause the product and/or operator
to be propelled in any direction, and possibly lose
control of the product. Blade thrust can occur without
warning if the product snags, stalls or binds. Blade
thrust is more likely to occur in areas where it is
difficult to see the material being cut.
• Avoid to cut with the area of the blade between the
12 o'clock and 3 o'clock positions. Because of the
speed of rotation of the blade, blade thrust can occur
if you attempt to cut thick stems with this area of the
blade.
• Always slow the engine to idle speed after each
working operation. Long periods at full throttle
61999 - 001 - 14.06.2023

without any load on the engine can lead to serious
engine damage.
• Listen out for warning signals or shouts when
you wear hearing protection. Always remove your
hearing protection as soon as the engine stops.
• Overexposure to vibration can lead to circulatory
damage or nerve damage in people who have
impaired circulation. Contact your doctor if you
experience symptoms of overexposure to vibration.
These symptoms include numbness, loss of feeling,
tingling, pricking, pain, loss of strength, changes in
skin color or condition. These symptoms normally
appear in the fingers, hands or wrists.
• Do not use a product with a damaged spark plug
cap.
• Do not use a product with a damaged muffler.
• Keep all parts of your body away from the rotating
cutting equipment and hot surfaces.
• Always wear protective gloves when you touch the
grass blade.
Personal protective equipment
WARNING: Read the warning
instructions that follow before you use the
product.
• Always use approved personal protective equipment
when you use the product. Personal protective
equipment cannot fully prevent injury but it
decreases the degree of injury if an accident does
occur. Let your dealer help you select the right
equipment.
• Use a protective helmet where there is a risk of
falling objects.
• Use approved hearing protection that provides
adequate noise reduction. Long-term exposure to
noise can result in permanent hearing impairment.
• Use approved eye protection. If you use a visor,
you must also use approved protective goggles.
Approved protective goggles must comply with the
ANSI Z87.1 standard in the USA or EN 166 in EU
countries.
• Use a visor for face protection. A visor is not enough
for protection of the eyes.
+
• Use gloves when necessary, for example when you
attach, examine or clean the cutting equipment.
• Use sturdy non-slip boots.
• Use clothing made of a strong fabric. Always use
heavy, long pants and long sleeves. Do not use
loose clothing that can catch on twigs and branches.
Do not wear jewelry, short pants, sandals or go with
bare feet. Put your hair up safely above shoulder
level.
• Keep first aid equipment close at hand.

To do a check of the cutting attachment guard
WARNING: Do not use a cutting
attachment without an approved and
correctly attached cutting attachment guard.
See To install the cutting attachment guard
and the grass blade on page 12 .
WARNING: Always use the
recommended cutting attachment guard for
the cutting attachment that you use. If an
incorrect or faulty cutting attachment guard
is fitted this can cause serious personal
injury. See intructions under heading
To
install the cutting attachment guard and the
grass blade on page 12 .
The cutting attachment guard prevents injuries from
objects that eject in the direction of the operator. It
also prevents injuries that occur if you touch the cutting
attachment.

damaged or cracked.
2. Replace the guard if it has been exposed to impact
or is cracked.
To do a check of the vibration damping system
Note: Use of incorrectly wound cord or an incorrect
cutting attachment increases the level of vibration. See
instructions under
Assembly on page 12 .
The vibration damping system decreases vibration in
the handles to a minimum which makes the operation
easier. The vibration damping system of the product
81999 - 001 - 14.06.2023

decreases the transfer of vibration between the engine
unit and the shaft unit of the product.
1. Stop the engine.
2. Do a visual check for deformation and damage for
example, cracks.
3. Make sure you attach the elements of the vibration
damping system correctly.
To do a check of the muffler
WARNING: A used muffler/spark
arrester and spark arrester mounting
face may contain deposits of combustion
particles on the surfaces that may be
carcinogenic. To avoid skin contact and
inhalation of such particles when cleaning
and/or servicing the spark arrester, make
sure you always:
• wear gloves;
• clean and/or service in a well ventilated
area;
• do not use pressurized air to clean the
spark arrester screen;
• use a steel brush and brush away from
your body when cleaning the spark
arrester.
WARNING: Do not use a product that
has a damaged muffler or a muffler that
is in bad condition. Return the product to
a Husqvarna dealer/service station if the
muffler is damaged.
WARNING: Do not use the product if
the spark arrester screen on the muffler is
missing or damaged.
WARNING: The muffler becomes very
hot during and after operation and also at
idle speed. Use protective gloves to prevent
burn injuries.
The muffler keeps noise levels to a minimum and points
exhaust fumes away from the operator.
1. Stop the engine.
2. Do a visual check for damage and deformation.
Note: The inner surfaces of the muffler contain
chemicals that can cause cancer. Be careful not to
touch these elements if the muffler is damaged.
3. Make sure that the muffler is correctly attached to
the product.
Note: Do not remove the muffler from the product.
4. If the muffler on your product has a spark arrester
screen, do a visual check.
a) Replace the spark arrester screen if it is
damaged.
b) Clean the spark arrester screen if it is blocked.
Refer to for more information.
CAUTION: If the spark arrester
screen is blocked the product becomes
too hot and this causes damage to the
cylinder and piston.
1999 - 001 - 14.06.2023 9

To attach and remove the locknut
WARNING: Stop the engine, use
protective gloves and be careful around the
sharp edges of the cutting attachment.
A locknut is used to attach some types of cutting
attachments. The locknut has a left thread.
• To attach, tighten the locknut in the opposite
direction to the direction of turning of the cutting
attachment.
• To remove the locknut, loosen the locknut in the
same direction as the cutting attachment rotates.
• To loosen and tighten the locknut, use a socket
wrench with a long shaft. The arrow in the picture
shows the area where you can operate the socket
wrench.
WARNING: When you loosen and
tighten the locknut, there is a risk of
injury from the blade. You must always
make sure that the blade guard prevents
injury to your hand when you do this.
Note: Make sure that you can not turn the locknut by
hand. Replace the nut if the nylon lining does not have
a resistance of a minimum of 1.5 Nm. The locknut must
be replaced after it has been put on approximately 10
times.
Cutting equipment
• Use the blades and grass knives to cut coarse grass.
• Use the trimmer head to cut grass.
• An incorrectly sharpened or damaged blade
increases the risk of accidents. Keep the teeth of the
blade correctly sharpened. Follow the instructions in
To sharpen the grass knife and grass blade on page
20 and use the recommended file gauge.
• Examine the cutting attachment for damage and
cracks. Replace damaged cutting attachment.
• Only use cutting attachments with recommended
cutting attachment guards. Refer to
Accessories on
page 24
.
Trimmer head
WARNING: Always make sure that
the trimmer line is wound tightly and
equally around the drum to prevent harmful
vibration.
• Only use recommended cutting attachments.
• The length of the trimmer line is important. For a
longer trimmer line, more engine power is necessary
than for a shorter trimmer line of the same diameter.
• Do not move the installation position of the trimmer
guard.
• Make sure that the cutter on the trimmer guard is
not damaged. The cutter cuts the trimmer line to the
correct length.
