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

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

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.

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

adjusting the high speed
needle. Therefore

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

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

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.
