Personal protective equipment
SAFETY INSTRUCTIONS
!WARNING!
Never use a machine with defective
safety equipment. Follow the control,
maintenance and service instructions
described in this section.
1. Throttle trigger
lock
The throttle trigger lock is
designed to prevent the
throttle from accidentally
being engaged. When the
trigger lock (A) is pressed
into the handle (= when you
hold the handle) the throttle
(B) is released. When the
grip on the handle is
released the throttle and the
throttle trigger lock return
to their original positions.
This takes place via two
independent return spring
systems.This means that the
throttle is automatically
locked in its “idling“
position.
2. Stop switch
The stop switch should be
used to stop the engine.
IMPORTANT INFORMATION
• A sweeper used incorrectly or carelessly can
become a dangerous tool, that can cause serious
or fatal injury to the operator or others. It is
extremely important that you read and understand
the content of this manual.
• When using a sweeper, personal protective
equipment approved by the appropriate
authorities must be used. Personal protective
equipment does not eliminate the risk of
accidents, however, it can reduce the effects of an
injury in the event of an accident. Ask your dealer
for help when choosing protective equipment.
GLOVES
Gloves should be worn when
necessary, e.g., when
assembling cutting
equipment.
EAR PROTECTION
Ear protection offering
sufficient dampening effect
should be used.
EYE PROTECTION
Blows from branches or
objects thrown by the
rotating cutting equipment
can damage the eyes.
BOOTS
Use anti-slip and stable
boots.
DUST MASK
Wear a dust mask.
CLOTHING
Wear clothes made of a
strong fabric and avoid loose
clothing that can catch on
shrubs and branches. Always
wear heavy, long pants. Do
not wear jewelry, short pants,
sandals or go barefoot.
Secure hair so it is above
shoulder level.
FIRST AID KIT
A first aid kit should be
carried by operators of
clearing saws, sweeper or
trimmers.

SAFETY INSTRUCTIONS
3. Vibration
damping system
Your machine is equipped
with a vibration damping
system, which is designed to
give as vibration-free and
comfortable use as possible.
Use of incorrectly wound
cord or incorrect cutting
equipment increases the
level of vibration.
The machine’s vibration
damping system reduces the
transfer of vibrations
between the engine unit/
cutting equipment and the
machine’s handle unit.
4. Muffler
The muffler is designed to
give the lowest possible noise
level and to direct the engine‘s
exhaust fumes away from the
operator. Muffler fitted with
catalytic converter is also
designed to reduce harmful
exhaust components.
In countries that have a warm
and dry climate the risk of fire
is obvious. We have therefore
fitted certain mufflers with a
spark arrest screen. Make sure
that your muffler is fitted
with this kind of screen.
It is extremely important that
the instructions for checking,
maintaining and servicing the
muffler are followed. (see the
section “Control, maintenance
and service of the machine‘s
safety equipment“).
!
WARNING!
Mufflers fitted with catalytic converters
become extremely hot during use and
after stopping. This also applies at idling
speeds. Contact can result in burns to
the skin. Be observant to the risk of fire!
!
WARNING!
Bear in mind that exhaust fumes:
• contain carbon monoxide, which can
cause carbon monoxide poisoning.
Therefore never start or run the machine
indoors.
• are hot and can contain sparks that can
cause fires. Never start the machine
indoors or close to inflammable material.
!WARNING!
Over exposure to vibrations can result in
blood-vessel or nerve injury to persons
suffering with blood circulation problems.
Seek medical attention if you experience
physical symptoms that can be related to
over exposure to vibrations. Examples of
such symptoms are “numbness“, lack of
feeling, “tickling“, “pricking“, “pain“ lack of
or a reduction in normal strength, changes
in the colour of the skin or its surfaces.
These symptoms normally appear in the
fingers, hands or wrists.

General working instructions
SAFETY INSTRUCTIONS
Basic safety precautions
1.Observe your surroundings:
•To ensure that people, animals or other things cannot affect
your control of the machine.
•To prevent the above-mentioned from coming into contact
with the sweeper or being hit by loose objects that are
thrown out.
•NOTE! Never use a machine without the possibility of
calling for help in the event of an accident.
2. Avoid usage in
unfavourable weather
conditions. For example,
thick fog, heavy rain,
strong winds or extreme
cold, etc. To work in bad
weather conditions is tiring
and can create dangerous
circumstances, e.g. slippery
surfaces.
3. Make sure you can walk
and stand safely. Look out
for any obstacles with
unexpected movement
(roots, stones, branches,
pits, ditches, etc.). Take
great care when working
on sloping ground.
IMPORTANT INFORMATION
•This section describes the basic safety
precautions for working with the sweeper.
•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.
Safety instructions before starting work
•Inspect the working area. Remove all loose objects, such as
stones, broken glass, nails, steel wire, twine and the like that
could be thrown outwards or become entangled in the
sweeper.
•Keep others at a safe distance. Children, animals, onlookers
and helpers should stand outside of the safety zone of 15 m
(50 feet). Stop the machine immediately if any one should
approach.
•When adjusting the carburettor, make sure that the sweeper
rollers are held against the ground and that no one is nearby.
•Make sure the sweeper rollers always stop when the engine is
idling.
•Make sure the handle and safety features are in order. Never
use a machine that has parts missing or has been changed in
relation to the specification.
•Only use the machine for the purpose it was intended for.
•Check the entire machine
before starting work.
Replace damaged parts.
Check for fuel leakage and
that all safety guards and
covers are complete and
fastened securely. Check all
nuts and bolts.
•Check that the sweeper
rollers are not cracked or
damaged in any other way.
4. The engine should be switched off before moving.
5. Never put the machine down with the engine running

English –9
!WARNING!
Beware of thrown objects. Always wear eye
protection. Never lean over the sweeper
rollers. Stones rubbish etc. can be thrown
up into the eyes resulting in blindness or
other serious injury.
Keep unauthorised persons at a distance.
Children, animals, onlookers and helpers
should be outside the safety zone of 15
meters (50 feet). Stop the machine immedi-
ately if anyone approaches.
The bevel gear unit can get hot during use
and may remain so for a while afterwards.
There is a risk of slight burns if you touch it.
Run the sweeper at full (or almost full) throttle, with the
rubber blades resting on the surface.
SAFETY INSTRUCTIONS
When you want to clear
narrow areas, such as
pavements, the machine can
be used so that it throws the
material straight ahead of you.
If you want to cover wider
areas you may need to work at
an angle so that long heaps
build up on one side. Long
heaps consisting of light
material can be gathered
together in a single line or pile
for collecting later, while hard
or bulky material may have to
be collected in several long
heaps.To clear in corners you
can change the direction of
rotation by turning over the
machine.
!WARNING! When you turn the machine
over, litter is thrown backwards towards the
user. Use a lower engine speed when you
reverse with the machine and remember
that it is easy to trip over material that is
thrown out!
•The sweeper works best when the rubber blades can quickly
slide over or stroke the surface. New or replaced sweeper
rollers tend to stick or drag on hard surfaces, and should
therefore be run in properly before use. The easy way to run
them in is to run the machine at full throttle for 3–5
minutes on loose gravel or a similarly abrasive material. After
running-in the sweeper can easily clear a wide variety of
materials, from snow and puddles of water, to heavier
objects such as gravel and wood chippings. With practice
you will learn how the sweeper works, but you must think of
safety right from the start!
•Always drop to idling speed after each working operation.
Longer periods running at full throttle without loading the
engine (that is without resistance, which the engine feels
from the sweeper rollers when sweeping) can lead to serious
engine damage.
•If heavy vibrations occur, stop the engine. Remove the spark
plug cable from the spark plug. Check that the machine is
not damaged. Repair any damage.
Keep your working angle
low.
A large working angle could
cause you to lose control!
CAUTION! It is both tiring and unnecessary to raise
the rubber blades or hold them above the surface
while you are working.
!WARNING! Maintain a low working angle
with the surface! If the working angle is
high the sweeper will tend to move towards
you and there is a risk you will lose control
over the machine.
The sweeper rollers may start turning when
the sweeper is started! Always hold the
machine firmly when you start it up. Watch
out for objects that could become en-
tangled in the rotating sweeper rollers or
thrown out by them.
ALWAYS WATCH OUT FOR OBJECTS
THAT ARE THROWN OUT!
Even though the sweeper rollers do not
exert the same force as a lawn mower
blade, for example, you should avoid
working with materials that could cause
damage to people or property if they are
thrown out.

FUEL HANDLING
Fuel mixture
!WARNING!
Always provide good ventilation when
handling fuel.
NOTE!
The machine is fitted with a two-stroke engine and must
always be run on a mixture of gasoline and two-stroke oil. It is
important to measure the quantity of oil accurately, to ensure
the correct mixture ratio. Small discrepancies in the amount of
oil have a great bearing on the proportions of the fuel mixture
when mixing small amounts of fuel.

Gasoline
NOTE!
Always use high grade
unleaded oil mixed gasoline
(minimum 87 RON).
Leaded fuel will destroy the
catalytic converter and it
will no longer serve its
purpose.
•This engine is certified to
operate on unleaded
gasoline.
•The lowest recommended
octane rating is 87. If you
run the engine on lower
octane rating than 87 so-
called “knocking“can
occur. This leads to an
increased engine
temperature, which can
result in a serious engine
breakdown.
•When working at
continuous high revs a
higher octane rating is
recommended.
Two-stroke oil
•For the best results use
HUSQVARNA two-stroke
oil, which has been
specially developed for
clearing saws and chain
saws.
Mixing ratio 1:50 (2%).
•Never use two-stroke oil
intended for water cooled
outboard motors, so-called
outboard motor oil.
•Never use oil intended of
four-stroke engines.
•Clean around the fuel cap.
Contamination in the tank
can disrupt operations.
•Ensure that the fuel is well
mixed by shaking the
container before filling the
tank.
WARNING!
The following precautions reduce the risk of
fire:
Do not smoke or place any sources of heat
in the vicinity of the fuel. Never refuel when
the engine is running. Always stop the
engine and let it cool for a few minutes
before refuelling. Open the fuel cap slowly
when fuelling so that any over pressure is
released slowly. Tighten the fuel cap
carefully after refuelling. Always move the
machine from the fuelling place before
starting.
!
Fuelling
!WARNING!
The catalytic converter muffler gets very hot
during and after use. This also applies
during idling. Be aware of the fire hazard,
especially when handling the saw near
flammable substances or vapours.
Min. 3 m
(10 ft)
Mixture
•Always mix gasoline and oil in a clean container intended for
fuel.
•Always start by filling half the quantity of gasoline required.
Then add the entire oil quantity. Mix (shake) the fuel
mixture. Fill the remaining quantity of gasoline.
•Mix (shake) the fuel mixture carefully before filling in the
machine‘s fuel tank.
•Do not mix more than max. one month’s supply of fuel.
•If the machine is not used for a long period of time, the fuel
tank should be emptied and cleaned.
• This engine is certified to operate on unleaded gasoline.

Conditions
•Before any adjustments are made the airfilter should be clean
and the airfilter cover fitted. Adjusting the carburetor while
a dirty airfilter is in use will result in a leaner mixture when
the filter is finally cleaned. This can give rise to serious
engine damage.
•Carefully turn the L and H needle to the mid point between
fully turned in and fully turned out..
•Do not attempt to adjust the needles beyond the stops as
damage can occur.
•Now start the machine according to the starting instructions
and run it warm for 10 minutes.
NOTE! If the sweeper rollers rotates/moves the T screw should
be turned anti-clockwise until the sweeper rollers stops.
Carburetor
Your Husqvarna product has been designed and manufactured
to specifications that reduce harmful emissions.
After your unit has been run 8-10 tanks of fuel the engine has
broken in.To ensure that your unit is at peak performance and
producing the least amount of harmful emissions after break
in, have your authorized servicing dealer, who has a revolution
counter at his disposal, to adjust your carburetor for optimum
operating conditions.
Basic setting
•The carburetor is set to its basic setting when test run at the
factory. The basic setting should be kept during the
machine‘s first working hours. Thereafter the carburetor
should be finely adjusted. Fine adjustment should be carried
out by a skilled technician.
NOTE! If the sweeper rollers rotates/moves while the engine is
idling theT-screw should be turned anti-clockwise until the
sweeper rollers stops.
Rec. idling speed: 2 700 rpm.
Recommended max. speed: See “Technical Data” .
!WARNING!
The complete clutch cover with shaft
must be fitted before the machine is
started, otherwise the clutch can become
loose and cause personal injury.
Operation
•The carburetor governs the
engine‘s speed via the
throttle. Air/fuel is mixed
in the carburetor. The air/
fuel mixture is adjustable.
To take advantage of the
engine‘s optimal output
the adjustment must be
correct.
•The setting of the
carburetor means that the
engine is adapted to local
conditions, for example,
the climate, altitude,
gasoline and the type of 2-
stroke oil.
•The carburetor is equipped
with three adjustment
possibilities:
L =Low speed needle
H=High speed needle
T=Idle speed adjuster screw
•The fuel quantity in relation to the air flow permitted by the
throttle opening is adjusted using the L and H-needles.
Turning the needles clockwise gives a leaner fuel mixture
(less fuel) and turning them anti-clockwise gives a richer fuel
mixture (more fuel). A leaner mixture gives high revs while a
richer mixture give less revs.
•The T-screw regulates the position of the throttle while the
engine is idling. Turning the screw clockwise gives a higher
idling speed while turning it anti-clockwise gives a lower
idling speed.
L
+ 1/4
WARNING!
If the idling speed cannot be adjusted so
that the sweeper rollers stops, contact
your service workshop. Do not use the
machine until it has been correctly
adjusted or repaired.

MAINTENANCE
Low speed needle L
Try to find the highest idling
speed, turning the low speed
needle L clockwise
respectively counter-
clockwise. When the highest
speed has been found, turn
the low speed needle L 1/4
turn counter-clockwise.
NOTE! If the sweeper rollers
rotates/moves in the idling
position, turn the idling
speed screwT counter-
clockwise until the sweeper
rollers stops.

English –15
Correctly adjusted carburetor
A correctly adjusted carburetor means that the machine
accelerates without hesitation and the machine 4-cycles a little
at max speed. Furthermore, the sweeper rollers must not
rotate/move at idling. A too lean adjusted low speed needle L
may cause starting difficulties and bad acceleration. A too lean
adjusted high speed needle H gives lower power = less capacity,
bad acceleration and/or damage to the engine. A too rich
adjustment of the two speed needles L and H gives accelera-
tion problems or too low working speed.
MAINTENANCE
High speed needle H
H
The high speed needle
affects the machine’s power,
speed, temperature and fuel
consumption. A too lean
adjustment on the high
speed needle H (the high
speed needle H is screwed in
too much) gives a too high
speed resulting in engine
damage. Do not allow the
engine to run at full speed
for more than 10 seconds.
Apply full throttle and turn
the high speed needle H
slowly anticlockwise until
the engine runs unevenly.
The high speed needle H is
then turned slowly clockwise
a little until the engine runs
smoothly. Note the engine
should be run unloaded
when adjusting the high
speed needle.
Therefore dismantle the
sweeper rollers, nut, support
flange and disc drive before
adjusting the high speed
needle.The high speed
needle is adjusted correctly
when the machine ‘splatters’
a little.
NOTE! For optimum setting of the carburetor, contact a
qualified servicing dealer who has a revolution counter at his
disposal.
Final setting of the idling speed T
Adjust the idling speed with
the screwT, if it is necessary
to readjust. First turn the
idle speed adjusting screwT
clockwise until the sweeper
rollers starts to rotate/move.
Then turn, counter-clock-
wise until the sweeper rollers
stops. A correctly adjusted
idle speed setting occurs
when the engine runs
smoothly in every position.
It should also be good
margin to the rpm when the
sweeper rollers starts to
rotate/move.
CAUTION! Contact your servicing dealer, if the idle speed
setting cannot be adjusted so that the sweeper rollers stops.
Do not use the machine until it has been properly adjusted
or repaired.

MAINTENANCE
Muffler
NOTE!
Some mufflers are fitted with a catalytic converter. See
“Technical data”to see whether your machine is fitted with a
catalytic converter.
The muffler is designed to
dampen the noise level and to
direct the exhaust fumes away
from the user.The exhaust
fumes are hot and can
contain sparks, which can
result in fire if the exhaust
fumes are directed towards a
dry and inflammable mate-
rial. Some mufflers are
equipped with a special spark
arrest screen. If your machine
is fitted with this type of
screen it should be cleaned
regularly. This is done using a
wire sweeper. On mufflers
without a catalytic converter
the screen should be cleaned
weekly, or replaced if
necessary. On mufflers fitted
with a catalytic converter the
screen should be checked and
cleaned monthly. If the
screen is damaged it should
be replaced. If the screen is
frequently blocked, this can
be a sign that the function of
the catalytic converter is
impaired. Contact your
dealer to inspect the muffler.
A blocked screen will cause
the engine to overheat
resulting in damage to the
cylinder and piston. Also see
under “Maintenance”.
NOTE! Never use a machine
with a defective muffler.
!WARNING!
Mufflers fitted with catalytic converters
become extremely hot during use and after
stopping. This also applies at idling speeds.
Contact can result in burns to the skin. Be
observant to the risk of fire!
Cooling system
To maintain as low operating
temperature as possible the
engine is equipped with a
cooling system.The cooling
system consists of:
1.An air intake on the starter
unit.
2.Cooling fins on the
flywheel.
3.Cooling fins on the
cylinder
4.Cylinder cover (leads cold
air onto the cylinder).
1
4
3
2
Clean the cooling system using a sweeper at least once a week,
in difficult conditions more often.
A dirty or blocked cooling system leads to the engine
overheating resulting in damage to the cylinder and piston.
Spark plug
The condition of the spark
plug is affected by:
•An incorrect carburetor
setting.
•An incorrect fuel mixture
(too much or faulty oil).
•A dirty air filter.
These factors cause deposits on the spark plug electrode that
may result in malfunction or starting difficulties. If the
machine is low on power, difficult to start or runs poorly
while idling always check the spark plug first. If the spark
plug is dirty, clean it and at the same time check that the
electrode gap is 0.5 mm.The spark plug should be changed
after about one month of operation or earlier if necessary.
NOTE! Always use the recommended type of spark plug. An
incorrect spark plug can damage the cylinder/piston.

MAINTENANCE
NOTE: Use only HUSQVARNA replacement parts. Use of
other brands of replacement parts can cause damage to your
unit or injury to the operator or others. Your warranty does
not cover damage or liability caused by the use of accessories
and/or attachments not specifically recommended by HUS-
QVARNA.
Maintenance schedule
Below you will find some general maintenance instructions.
NOTE! If you are unfamiliar with any of the listed
maintenance instructions, please contact an authorized
servicing dealer.
Daily maintenance
•Check throttle trigger and throttle trigger lockout function.
•Check stop switch function.
•Check that sweeping attachment does not rotate at idling.
•Clean the exterior of the machine.
•Check that the sweeper rolls are undamaged.
•Check the sweeper for cracks and chips or damage. Replace
if necessary.
•A non-balanced sweeper induces heavy vibrations that may
damage the machine.
•Check that the locking nut is sufficiently tightened.
•Check that nuts and screws are sufficiently tightened.
•Check for fuel leaks.
•Clean the air filter (see maintenace for air filter).
Weekly maintenance
•Check the starter, especially cord and return spring.
•Clean the carburetor area.
•Clean the exterior of the spark plug.
•Remove it and check the electrode gap.
•Adjust it to 0,5 mm (.020"), or change the spark plug.
•Clean the cooling fins on the cylinder and check that the air
intake at the starter is not clogged.
•Check that the angle gear is not leaking.
•Clean or replace the muffler’s spark arrest screen (only
mufflers with a catalytic converter).
Monthly maintenance
•Clean the fuel tank.
•Clean the exterior of the carburetor and the space around it.
•Clean the fan and the space around it.
•Check fuel hose for cracks or other damage. Change if
necessary.
•Change fuel filter in fuel tank.
•Check clutch, clutch spring and clutch drum for wear.
Change if necessary.
•Check electrical wires and connections.
•Change the spark plug.
•Change the airfilter.
•Check and clean the muffler’s spark arrest screen if necessary
(only mufflers with a catalytic converter).
•Check and if necessary, clean the exhaust port at cylinder
from carbon deposits.
Air filter
The air filter should be
cleaned regularly removing
dust and dirt to avoid:
•carburetor malfunction
•starting problems
•reduced engine power
•unnecessary wear to engine
parts
•abnormal fuel consumption
Clean the filter after every 8
hours or more regularly if
operating conditions are
exceptionally dusty.
Cleaning the air filter
Dismantle the air filter cover and remove the air filter. Wash in
clean, warm soapy water. An air filter used for a long period of
time can never be cleaned completely.Therefore it is necessary
to replace the filter from time to time with a new filter. A
damaged air filter must always be replaced.
The angle gear is filled with a
sufficient quantity of grease at
the factory.
Normally, the grease does not
need to be changed except
when repairs are carried out.
Angle gear
Oiling the air filter
Always use HUSQVARNA
filter oil, order no. 503 47
73-01.The filter oil contains
a solvent to make it spread
evenly through the filter. You
should therefore avoid skin
contact. Put the filter in a
plastic bag and the pour the
filter oil over it. Knead the
plastic bag to distribute the
oil. Squeeze the excess oil out
of the filter inside the plastic
bag and pour off the excess
before fitting the filter on the
machine. Never use common
engine oil.This would drain through the filter quite quickly
and collect in the bottom.
IMPORTANT INFORMATION!
The sweeper is often used under dusty conditions. It
is extremely important to maintain the air filter regu-
larly, often daily. The air filter must be oiled in order to
work satisfactorily.
