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.

• Obtain maximum clearing capacity.
IMPORTANT INFORMATION
The section describes how through correct
maintenance and through using the right type of
cutting equipment you can obtain maximum
clearing capacity and increase the service life of
the cutting equipment.
• Increase the service life of the cutting equipment.
Two basic rules:
•
Only use the cutting and guard equipment we
recommend! See chapter “Technical data“.
1)Only use the cutting
and guard equipment
we recommend! See
chapter “Technical
data“.
Trimmer head
• 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“.
2)Check the cutting
equipment with regard
to damage and crack
formation. Damaged
cutting equipment
should always be
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.

SAFETY INSTRUCTIONS
General working instructions
Basic working techniques
• 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.
IMPORTANT INFORMATION
•
•
This section takes up the basic safety
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 and plastic
knifes
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.
• 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.
• 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.
• 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.
• 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.
6.. Do not over-reach
7.Keep Cutting attachment below waist level.

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!
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.
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.

FUEL HANDLING
Mixture
Fuel mixture
NOTE!
• Always mix gasoline and oil in a clean container intended
for gasoline.
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 clearing saw 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.
!
Gasoline
• This engine is certified to operate on unleaded 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 high grade
unleaded oil mixed gasoline
(minimum 87 RON).
Leaded fuel will destroy the
catalytic converter and it
will no longer serve its
purpose.
Fuelling
WARNING!
• This engine is certified to
operate on unleaded
gasoline.
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.
• The lowest recommended
octane rating is 90. If you
run the engine on a
gasoline 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.
• Ensure that the fuel is
well mixed by shaking the
container before filling
the tank.
Two-stroke oil

Functioning
• The carburetor governs the engine speed via the throttle
trigger. In the carburetor, air/fuel is mixed. This air/fuel
mixture is adjustable. If you want to take advantage of the
maximum output of the engine, the setting must be corret.
Fine adjustment
• When the machine has been ”run-in” the carburetor 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.
• 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.
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 carburetor has three
adjustment possibilities:
L= Low speed needle
H= High speed
adjustment screw
• Carefully turn the L and H needle to the mid point between
fully turned in and fully turned out.
T= Idle speed
adjustment screw
• 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.
Low speed needle L
Try to find the highest idling
speed, turning the low speed
needle L clockwise
• 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.

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 =

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

Note the engine should be run unloaded when adjusting the

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 carburetor, contact a

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 you clearing saw 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

• 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.
• 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.
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.
• Check that the angle gear is filled with grease up to 3/4. Use
special grease.
• Clean the air filter.
• Clean or replace the muffler’s spark arrest screen (not on
mufflers with a catalytic converter).
