The machine‘s safety equipment  
This section describes the machine‘s safety equipment, its  
function and how checks and maintenance are carried out to  
ensure that it operates correctly. (See the chapter “What is  
what“ to locate where this equipment is positioned on your  
machine.)  
MPORTANT INFORMATION  
A clearing saw, brushcutter or trimmer 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.

equipment. Follow the control,  
maintenance and service instructions  
described in this section.  
When using a trimmer, 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.  
1. Throttle trigger  
lock  
A
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“

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“).  
Use of incorrectly wound  
cord or incorrect cutting  
equipment increases the  
level of vibration.

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.

replaced.  
7. Locking nut  
• Protect your hand from  
injury when assembling,  
use the blade guard as  
protection when tightening  
with a socket spanner.  
Tighten the nut by turning  
against the direction of  
rotation. Loosen the nut by  
turning in the direction of  
rotation. (NOTE! the nut  
has a left-hand thread).  
• Generally smaller machines require a small trimmer head  
and vice versa. This is because when clearing using a cord  
the engine must throw out the cord radially from the  
trimmer head and also meet resistance from the grass being  
cleared.  
• The length of the cord is also important. A longer cord  
requires greater engine power than a shorter cord of the  
same diameter.  
• Make sure the knife positioned on the trimmer guard is  
intact. This is used to cut the cord to the correct length.  
• Tighten the nut using a  
socket spanner, 35 - 50  
Nm (3.5 - 5 kpm).  
• To increase the life of the cord it can be soaked in water for  
a few days. This will make the line tougher and it will keep  
longer.  
NOTE!  
The locking nut‘s nylon lock must not be so worn that it can  
be turned by hand. The lock shall hold at least 1.5 Nm. The  
nut should be replaced after it has been put on approx. 10  
times.  
IMPORTANT INFORMATION  
Always ensure the trimmer cord is wound tightly  
and evenly around the drum, otherwise harmful  
vibrations will occur.  
WARNING!  
Never use a machine with defective  
safety equipment. The safety equipment  
should be maintained as described in this  
section. If your machine does not meet  
any of these controls you should contact  
your service workshop.  
!
WARNING!  
Always stop the engine before starting  
work on any part of the cutting equipment.  
!
This continues to rotate even after the  
throttle has been released. Ensure that the  
cutting equipment has stopped completely  
and remove the cable from the spark plug  
before you start to work on it.

precautions for working with the trimmer.  
If you encounter a situation where you are  
uncertain how to proceed you should ask an  
expert. Contact your dealer or your service  
workshop.  
WARNING!  
Sometimes branches, grass or wood can  
get caught between the guard and cutting  
equipment. Always stop the engine when  
cleaning.  
Avoid all usage which you consider to be  
!
beyond your capability.  
Basic safety precautions  
Grass trimming using the trimmer head  
1.Observe your surroundings:  
• Hold the trimmer head  
just above the ground at  
an angle. It is the end of  
the cord that carries out  
the work. Let the cord  
work at its own pace. Do  
not press the cord into  
the area to be cut.  
• To ensure that people, animals or other things cannot affect  
your control of the machine.  
• To ensure that the above mentioned do not come into  
contact with the cutting equipment or objects that can be  
thrown by the cutting equipment.  
NOTE! Never use a machine without the possibility of  
calling for help in the event of an accident.  
• The cord can easily  
remove grass and weeds  
up against walls, fences,  
trees and borders,  
however, it can also  
damage sensitive bark on  
trees and bushes and  
damage fence posts.  
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.  
• Reduce the risk of  
damaging plants by  
shortening the cord to  
10-12 cm and reducing  
the engine speed.  
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.  
4.The engine should be switched off before moving. When  
moving over longer distances and transporting the transport  
guard should be used.  
5.Never put the machine down with the engine running unless  
you have good sight of it.

SAFETY INSTRUCTIONS  
Clearing  
Trimming  
• The clearing technique  
removes all unwanted  
vegetation. Keep the  
trimmer head just above  
the ground and tilt it.  
Let the end of the cord  
strike the ground around  
trees, posts, statues and  
the like. NOTE! This  
technique increases the  
wear on the cord.  
• The trimmer is ideal to  
cut grass that is difficult  
to reach using a normal  
lawn mower. Keep the  
cord parallel to the  
ground when cutting.  
Avoid pressing the  
trimmer head against the  
ground as this can ruin  
the lawn and damage the  
tool.  
• The cord wears quicker  
and must be fed forward  
more often when  
working against stones,  
brick, concrete, metal  
fences, etc. than when  
coming into contact  
with trees and wooden  
fences.  
• Do not allow the  
trimmer head to  
constantly come into  
contact with the ground  
during normal cutting  
procedures. Constant  
contact can cause damage  
and wear to the trimmer  
head.  
• When trimming and  
clearing you should use  
less than full throttle so  
that the cord lasts longer  
and to reduce the wear  
on the trimmer head.  
Sweeping  
• The rotating cord‘s  
fanning effect can be  
used for quick and easy  
cleaning. Hold the cord  
parallel to and above the  
area to be swept and  
move the trimmer from  
side to side.  
• When cutting and  
sweeping you should use  
full throttle to obtain the  
best results.  
WARNING!  
Warning for thrown objects. Always wear  
protective glasses. Never lean over the  
guard. Stones, rubbish, etc. can be thrown  
up into the eyes causing blindness or  
serious injury.  
Keep unauthorised persons at a distance.  
Children, animals, onlookers and helpers  
should be kept outside the safety zone of  
15 m (50 feet). Stop the machine  
!
immediately if anyone approaches.

NOTE!  
petrol.  
The machine is fitted with a two-stroke engine and must  
always be run on a mixture of petrol 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.  
• Always start by filling half the quantity of petrol required.  
Then add the entire oil quantity. Mix (shake) the fuel  
mixture. Fill the remaining quantity of petrol.  
• Mix (shake) the fuel mixture carefully before filling in the  
machine‘s fuel tank.  
WARNING!  
Always provide good ventilation when  
handling fuel.  
• 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.  
Petrol  
WARNING!  
NOTE!  
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.  
Always use an oil-mixed  
quality petrol (at least 90  
octane). If your machine is  
equipped with a catalytic  
converter, (see “technical  
data) an unleaded, oil  
mixed quality petrol  
should always be used. A  
leaded petrol will destroy  
the catalytic converter

Fuelling  
WARNING!  
The following precautions reduce the risk  
of fire:  
!
• The lowest  
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.  
recommended octane  
rating is 90. If you run  
the engine on a petrol  
with a lower octane  
rating than 90 so-called  
“knocking“ can occur.  
This leads to an  
increased engine  
temperature, which can  
result in a serious engine  
breakdown.  
• Clean around the fuel  
cap. Contamination in  
the tank can disrupt  
operations.  
• When working at  
continuous high revs a  
higher octane rating is  
recommended.

MAINTENANCE  
Basic setting  
Carburettor  
• The carburettor is set to its basic setting when test run at the  
Your Husqvarna product has been designed and  
manufactured to specifications that reduce harmful  
emissions.  
factory. The basic setting is richer than the optimal setting  
and should be kept during the machine‘s first working  
hours. Thereafter the carburettor should be finely adjusted.  
Fine adjustment should be carried out by a skilled  
technician.  
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 carburettor for optimum operating conditions.  
NOTE! If the cutting attachment rotates/moves while the  
engine is idling the T-screw should be turned anti-clockwise  
until the cutting attachment stops.  
Rec. idling speed: 2 700 rpm.  
WARNING!  
Recommended max. speed: See “technical data.  
The complete clutch cover with shaft  
!
must be fitted before the machine is  
started, otherwise the clutch can become  
loose and cause personal injury.  
WARNING!  
If the idling speed cannot be adjusted so  
that the cutting attachment stops,  
contact your service workshop. Do not  
use the machine until it has been  
correctly adjusted or repaired.  
!
Operation  
• The carburettor governs  
the engine‘s speed via the  
throttle. Air/fuel is mixed  
in the carburettor. The  
air/fuel mixture is  
adjustable. To take  
advantage of the engine‘s  
optimal output the  
adjustment must be  
correct.  
Fine adjustment  
• When the machine has been ”run-in” the carburettor should  
be finely adjusted. The fine adjustment should be carried  
out by qualified person. First adjust the L-jet, then the  
idling screw T and then the H-jet.  
Conditions  
• Before any adjustments are made the airfilter should be clean  
and the airfilter cover fitted. Adjusting the carburettor 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.  
• The setting of the  
carburettor means that  
the engine is adapted to  
local conditions, for  
example, the climate,  
altitude, petrol and the  
type of 2-stroke oil.  
• 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 cutting attachment rotates/moves the T screw  
should be turned anti-clockwise until the cutting attachment  
stops.  
• The carburettor is  
equipped with three  
adjustment possibilities:  
L = Low speed needle  
H = High speed needle  
T = Idle speed adjuster  
screw  
Low speed needle L  
Try to find the highest idling  
speed, turning the low speed  
needle L clockwise  
• 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.

+ 1/4  
NOTE! If the cutting  
attachment rotates/moves in  
the idling position, turn the  
idling speed screw T  
counter-clockwise until the  
cutting attachment stops.  
• 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.

MAINTENANCE  
Final setting of the idling speed T  
Adjust the idling speed with  
the screw T, if it is necessary  
to readjust. First turn the  
idle speed adjusting screw T  
clockwise until the cutting  
attachment starts to rotate/  
move.  
Correctly adjusted carburettor  
A correctly adjusted carburettor means that the machine  
accelerates without hesitation and the machine 4-cycles a  
little at max speed. Furthermore, the cutting attachment  
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 acceleration problems or too low working speed.  
Then turn, counter-  
clockwise until the cutting  
attachment 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  
cutting attachment starts to  
rotate/move.  
CAUTION! Contact your servicing dealer, if the idle speed  
setting cannot be adjusted so that the cutting attachment  
stops. Do not use the machine until it has been properly  
adjusted or repaired.  
High speed needle 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 cutting  
equipment, nut, support  
H
flange and disc drive before  
adjusting the high speed  
needle. The high speed needle is adjusted correctly when the  
machine ‘splatters’ a little . If the machine smokes heavily at  
the same time as it ‘splatters’ heavily the adjustment is too rich.  
NOTE! For optimum setting of the carburettor, contact a  
qualified servicing dealer who has a revolution counter at his  
disposal.

MAINTENANCE  
Muffler  
Cooling system  
NOTE!  
To maintain as low opera-  
ting temperature as possible  
the engine is equipped with  
a cooling system.  
Some mufflers are fitted with a catalytic converter. See  
Technical data” to see whether your machine is fitted with a  
catalytic converter.  
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  
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

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 brush. 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  
Air filter  
The air filter should be  
cleaned regularly removing  
dust and dirt to avoid:  
• carburettor malfunction  
• starting problems  
• reduced engine power  
• unnecessary wear to  
engine parts  
• abnormal fuel  
consumption  
Clean the filter after every  
25 hours or more regularly  
if operating conditions are  
exceptionally dusty.  
resulting in damage to the  
cylinder and piston. Also see  
under “Maintenance”.  
NOTE!  
Never use a machine with a defective muffler.  
Cleaning the air filter  
Dismantle the air filter  
cover and remove the air  
filter. Wash in clean, warm  
soapy water. Ensure that the  
filter is dry before refitting.  
An air filter used for a long  
period of time can never be  
cleaned completely.  
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!  
!
Therefore it is necessary to  
replace the filter from time  
to time with a new filter. A  
damaged air filter must  
always be replaced.
