4. Anti-vibration
system
The stop switch should be
used to stop the engine.
Your machine is equipped
with an anti-vibration system
that has been designed to
give as vibration-free and
comfortable usage as
possible.
The use of incorrectly
wound cord or blunt,
incorrect cutting equipment
(incorrect type or incorrectly
sharpened, see section “Filing
the blade”) 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.
3. Cutting
attachment guard
This guard is intended to
prevent objects from being
thrown towards the operator
and to protect the operator
from unintentionel contact
with the cutting attachment.
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.
WARNING!
Do not attach any blade to the unit

Sharpening the
grass blade
Cutting equipment
IMPORTANT INFORMATION
• See the cutting
equipment’s packaging for
correct filing instructions.
The section describes how through correct mainte-
nance and through using the right type of cutting
equipment you can reduce the machine‘s tendency to
kickback, obtain maximum clearing capacity and
increase the service life of the cutting equipment.
• The blades are sharpened
using a single cut flat file.
•
Only use the cutting and guard equipment we
recommend! See chapter “Technical data“.
• Sharpen all edges equally
to maintain the balance of
the blade.
•
Refer to the instructions for the cutting
equipment for the correct winding of cord
and for the selection of the right cord diameter.
•
•
Keep the blade’s teeht well and correctly
sharpened! Follow our recommendations. Also
refer to the instructions on the blade packaging.
Trimmer head
Maintain the correct setting. Follow our instruc-
tions and use the recommended filing gauge.
• Only use a trimmer head
and trimmer cord that is
recommended. These
have been tested by the
manufacturer to suit a
particular engine size.
This is especially
important when a fully
automatic trimmer head
is used. Only use the
cutting equipment we
recommend! See chapter
“Technical data“.
WARNING!
Incorrect cutting equipment or an
incorrectly sharpened blade increases
the risk of kickback.
!
Sharpening the
clearing blade
• See the cutting
equipment’s packaging for
correct filing instructions.
• 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.
• A correctly sharpened
blade is a prerequisite for
working efficiently and to
avoid unnecessary wear to
the blade and clearing saw.
• Make sure that the blade is
well supported when you
use the file. Use a 5,5 mm
round file with a file
holder.
• 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.
• The sharpening angle is
15°. Every other tooth is
sharpened to the right and
the intermediate tooth to
the left. When the blade
has been heavily pitted by
stones the upper side of
the teeth can, in
exceptional cases, need to
be dressed using a flat file.
In such cases this takes
place before sharpening
with the round file.
• 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.
IMPORTANT INFORMATION
Always ensure the trimmer cord is wound tightly
and evenly around the drum, otherwise harmful
vibrations will occur.
WARNING!
Always stop the engine before starting
work on any part of the cutting equipment.
!
Dressing the top side must
be carried out equally for
all teeth.
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.
• Adjust the setting. This
should be 1 mm.

•
This section covers basic safety precautions for
working with brushcutters and trimmers.
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.
You must understand the difference between
clearing, brush cutting and grass trimming before
using the machine.
Basic safety precautions
1.Observe your surroundings:
• 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.

SAFETY INSTRUCTIONS
Adjusting the harness and clearing saw
Basic clearing techniques
WARNING!
• 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 cutting equipment when trimming) can lead to
serious engine damage.
When working with the clearing saw it
should always be hooked in the harness. If
this is not done, you cannot control the
clearing saw safely and this can result in
injury to yourself or someone else. Never
use a harness with a defective quick
release catch.
!
Designations
Quick release
On the front is an easily
accessible, quick release
catch. Use this if the engine
should catch fire or in any
other emergency situation
when you quickly need to
take off the harness and
machine.
• Use a saw blade for
cutting woody growth
with thin stems.
• Use a grass knife or grass
blade for clearing grass.
• Use a trimmer head or
plastic blades for lighter
clearing work, for
example along verges or
around trees.
Even load on the
shoulders
A well-adjusted harness and
clearing saw significantly
facilitates working. Adjust
the harness for the best
working position. Tension
the side straps so that the
weight is evenly distributed
across the shoulders.
WARNING!
Sometimes branches, grass or wood can
get caught between the guard and cutting
equipment. Always stop the engine when
cleaning.
!
Correct height
Adjust the support strap so
that the cutting attachment
is parallel to the ground.
Correct balance
The cutting attachment
should rest lightly on the
ground. If you use a saw
blade it should balance
about 10 cm above the
ground to prevent contact
with stones and the like.
Adjust the position of the
support strap attachment
ring to balance the clearing
saw correctly.

Always use the correct equipment.
• A blade is used for all
types of high or thick
grass.
Always have well adjusted equipment.
Follow the safety instructions.
Organise the work well.
Always use full throttle when applying the blade.
Always use a sharp blade.
• The grass is cut down
with a sideways, swinging

!
o’clock).
Working methods
• Before you start clearing,
check the clearing area, its
condition, slopes, if there
are stones, pits, etc.
• If the blade is angled to the left when clearing the grass will
collect in a line, which makes collection easier, e.g. when
raking.
• Try to work rhythmically. Stand firmly with your feet apart.
Move forward after the return stroke and stand firmly again.
• On sloping ground the
pathway should run
parallel to the slope. It is
far easier to work along a
slope then up and down a
slope.
• Let the support cup rest lightly against the ground. It is used
to protect the blade from hitting the ground.
• Reduce the risk of material wrapping around the blade by
following these instructions:
a) Always work at full throttle.
b) Avoid the previously cut material during the return
stroke.
• The pathway should be
planned so that you avoid
going over ditches or other
obstacles.
• Stop the engine and remove the brushcutter from the
harness before you start to gather the cut material.
WARNING!
Neither the user of the tool or anyone else
may attempt to remove the cut material
!
while the engine is running or with the
blade rotating as this can result in serious
injury.
Stop the engine and blade before you
remove material that has wound around the
blade as otherwise there is a risk of injury.
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.
Brush cutting
using the saw
blade
• Cut through thin stems
and brush. Swing the
blade sideways in a sawing
motion.
• Avoid cutting in the
cutting region between 12
and 3 o‘clock on the
blade.
WARNING!
Beware of thrown objects. Always wear eye
protection. Never lean over the guard.
12
!
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
immediately if anyone approaches.

Trimming
Grass clearing
using the trimmer
head and plastic
blades.
• 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.
• 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.
• Do not allow the

contact with the ground
during normal cutting
procedures. Constant
contact can cause damage
and wear to the trimmer
head.
• Reduce the risk of
damaging plants by
shortening the cord to
10-12 cm and reducing
the engine speed.
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.
Clearing
• 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.
• When cutting and
sweeping you should use
full throttle to obtain the
best results.

WARNING!
Assembling:
When working with the clearing saw it
should always be hooked in the harness.
If this is not done, you cannot control the
clearing saw safely and this can result in
injury to yourself or someone else. Never
use a harness with a defective quick
release catch.
!
• Make sure the handle is
loose.
• Guide the cut-out on the
lower section of the shaft
into the coupling‘s
locking plate on the
upper section of the
shaft. The sections are
then locked together.
Quick release
On the front is an easily
accessible, quick release
catch. Use this if the engine
should catch fire or in any
other emergency situation
when you quickly need to
take off the harness and
machine.
• Tighten the handle.
Dismantling
• Undo the handle (at least
three turns).
• Press the handle towards
the coupling.
• Carefully twist the lower
section out of the lock.
Even load on the
shoulders
• Hold both parts of the
shaft and pull out the
lower section from the
coupling.
A well-adjusted harness and
clearing saw significantly
facilitates working. Adjust
the harness for the best
working position. Tension
the side straps so that the
weight is evenly distributed
across the shoulders.
Correct height
Adjust the support strap so
that the cutting attachment
is parallel to the ground.
Correct balance
The cutting attachment
should rest lightly on the
ground. If you use a saw
blade it should balance about
10 cm above the ground to
prevent contact with stones
and the like. Adjust the
position of the support strap
attachment ring to balance
the clearing saw correctly.

FUEL HANDLING
Mixture
Fuel mixture
NOTE!
• Always mix gasoline and oil in a clean container intended
for fuel.
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.
• 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.
WARNING!
Always provide good ventilation when
handling fuel.
!
• This engine is certified to operate on unleaded gasoline.
Gasoline
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.
!
NOTE!
Always use an oil-mixed
quality gasoline (at least 87
octane). If your machine is
equipped with a catalytic
converter, (see “technical
data”) an unleaded, oil
mixed quality gasoline
should always be used. A
leaded gasoline will destroy
the catalytic converter.
Fuelling
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.
• 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.
• 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.
• When working at
continuous high revs a
higher octane rating is
recommended.
Min. 3 m

CHOKE: Set the choke
control in the choke position.
AIR PURGE:
Press the air purge diaphragm
repeatedly until fuel begins to
fill the diaphragm. The
diaphragm need not be
completely filled.
For reasons of safety follow
these recommendations!
• Check the blade to ensure
that no cracks have formed
at the bottom of the teeth
or by the centre hole. The
most common reason why
cracks are formed is that
sharp corners have been
formed at the bottom of
the teeth while sharpening
or that the blade has been
used with dull teeth.
Warm engine
Use the same starting
procedure as for the cold
engine, but do not set the
choke control in the choke
position.
Discard a blade if cracks
are found.
• Check that the support
flange is not cracked due to
fatigue or due to being
tightened too much.
Discard the support flange
if it is cracked.
• Ensure the locking nut has
not lost its captive force.
The nut lock should have a
locking force of at least 1.5
Nm. The tightening
torque of the locking nut
should be 35-50 Nm.
• Check that the guard is not
damaged or cracked.
For throttle handles
without a start throttle
lock:
The start throttle position is
obtained by setting the
choke control in the choke
position and then returning
it to its original position.
Replace the guard if it is
exposed to impact or is
cracked.
• Check that the trimmer
head and spray guard are
not damaged or cracked.
Replace the trimmer head
or spray guard if they are
exposed to impact or are

mixture is adjustable. If
you want to take
advantage of the
maximum output of the
engine, the setting must be
corret.
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.
• The setting of the
carburetor means that the
engine is adjusted to local
conditions, for example
climate, altitude, gasoline
and type of two-stroke oil.
• The carburetor has three
adjustment possibilities:
L= Low speed needle
H= High speed
adjustment screw
T= Idle speed adjustment
screw
• The fuel quantity required
in proportion to the
airflow the throttle trigger
level allows is adjusted by
means of the L- and H-
needles. Turning the
needles clockwise gives a
leaner fuel mixture (less
fuel), turning them
counter-clockwise gives a
richer fuel mixture (more
fuel). A lean mixture gives
higher rpms and a rich one
lower rpms.
• The idling speed screw T regulates the position of the
throttle lever in the idling speed position. Turn the idling
speed screw clockwise gives a higher idling speed, turn it
counter-clockwise a lower idling speed.
• 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.

idle speed adjusting screw T
clockwise until the cutting
attachment starts to rotate/
move.
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 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

filter is dry before refitting. 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.
If the machine is used in dusty conditions the air filter
should be soaked in oil, see the section on “Oiling the air
filter“.
NOTE! Always use the recommended type of spark plug. An
incorrect spark plug can damage the cylinder/piston.

Maintenance schedule
• See the cutting
equipment’s packaging
for correct filing
instructions.
Below you will find some general maintenance instructions.
Daily maintenance
• Check throttle trigger and throttle trigger lockout function.
• Check stop switch function.
• Check that blade/trimmer head does not rotate at idling.
• Clean the exterior of the machine.
• Check that the harness is undamaged.
• Check the blade guard for damage or cracks.
• Change the guard in case of impacts or cracks.
• Check that the blade is properly centred, sharp, and without
cracks.
• A correctly sharpened
blade is a prerequisite for
working efficiently and to
avoid unnecessary wear to
the blade and clearing
saw.
• Make sure that the blade
is well supported when
you use the file. Use a 5.5
mm round file with a file
holder.
• Check the trimmer head for cracks and chips or damage.
Replace if necessary.
• A non-balanced blade/trimmer head induces heavy
vibrations that may damage the machine.
• Check that the blade nut is sufficiently tightened.
• Make sure that the blade transport guard is undamaged and
that it can be securely fitted.
• The sharpening angle is
15°. Every other tooth is
sharpened to the right
and the intermediate
tooth to the left. When
the blade has been heavily
pitted by stones the upper
side of the teeth can, in
exceptional cases, need to
be dressed using a flat file.
In such cases this takes
place before sharpening
with the round file.
• Check that nuts and screws are sufficiently tightened.
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 filled with grease up to 3/4. Use
special grease.
• Clean the air filter.
Dressing the top side
