SAFETY INSTRUCTIONS
Personal protective equipment
IMPORTANT INFORMATION
• If used incorrectly or carelessly this machine
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 the machine, 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.
WARNING!
!
GLOVES
Gloves must be worn
whenever required, for
example when fitting,
inspecting or cleaning
cutting equipment.
EAR PROTECTION
Ear protection offering
sufficient dampening
effect should be used.
EYE PROTECTION
Blows from branches or
objects thrown out by the
cutting equipment can
damage the eyes.
Remove your hearing protection as soon as
you stop the engine, so that you can hear
any noises or warning signals.
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.)
WARNING!
!
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.
Never use a machine with defective safety
equipment. Follow the control, maintenance
and service instructions described in this
section.
A
B
BOOTS
Use anti-slip and stable
boots.
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
The operator must carry a
first aid kit.

2. Stop switch
The stop switch should be
used to stop the engine.
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.
The machine’s vibration
damping system reduces
the transfer of vibrations
between the engine unit/
cutting equipment and the
machine’s handle unit.
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.
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.

SAFETY INSTRUCTIONS
Inspecting, maintaining and
servicing machine safety equipment
IMPORTANT INFORMATION
• All service and repairs to the machine require
special training.
• This applies especially to the machine‘s safety
equipment. If the machine does not meet any of
the controls listed below you should contact your
service workshop.
• The purchase of one of our products
guarantees that professional repair and servicing
will be carried out on it. If the point of purchase is
not one of our servicing dealers, please ask for
details of the closest service workshop.
1. Throttle trigger
lock
• Check that the throttle is
locked in the “idling
position“ when the
throttle trigger lock is in
its original position.
• Press in the throttle
trigger lock and make sure
it returns to its original
position when released.
• Ensure that the throttle
and throttle trigger lock
move easily and that their
return spring systems
function.
• See section “Start“. Start
the machine and apply
full throttle. Release the
throttle and check that the
cutting equipment stops
and remains at a standstill.
If the cutting equipment
moves with the throttle in
the idling position, then
the carburettor’s idling
setting must be checked.
See chapter
“Maintenance“.
3. Vibration
damping system
• Check the vibration
damping element
regularly for material
cracks and distortion.
• Check that the vibration
damping element is
undamaged and securely
attached.
4. Muffler
1.Never use a machine that
has a defective muffler.
2.Check regularly that the
muffler is secure.
3.If your muffler is fitted
with a spark arrest screen
then it should be cleaned
regularly. A blocked
screen leads to the engine
overheating with serious
damage as a result. Never
use a muffler with a
defective spark arrest
screen.
2. Stop switch
• Start the engine and make
sure that the engine stops
when the stop switch is
moved to the stop
position.

SAFETY INSTRUCTIONS
5. Cutting equipment
This section describes how through correct maintenance and
through using the right type of cutting equipment you can:
• Obtain maximum cutting capacity.
• Increase the service life of the cutting equipment.
1 Check the cutting
equipment with regard to
damage and crack
formation. Damaged
cutting equipment should
always be replaced.
2 Only use cutting
equipment recommended
by us! See the ”Technical
data” section.
3 Keep the chain cutting
teeth properly sharpened!
Follow our instructions
and use the
recommended file gauge.
A damaged or badly
sharpened chain increases
the risk of accidents.
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 carrying out
any work on the cutting equipment. This
will continue to move even after the throttle
has been released. Make sure the cutting
equipment has stopped completely and
disconnect the HT lead from the spark plug
before you start work on it.
Specification of blade and chain
When the cutting equipment supplied with your machine
becomes worn or damaged, you will need to replace it. Use
only the manufacturer approved bar and chain.
Guide bar
• Length (inches/cm)
4 Maintain the correct
raker clearance! Follow
our instructions and use
the recommended raker
gauge. Too large a
clearance increases the
risk of kickback.
5 Keep the chain properly
tesioned! If the chain is
slack it is more likely to
jump off and lead to
increased wear on the
bar, chain and drive
sprocket.
6 Keep cutting equipment
well lubricated and
properly maintained! A
poorly lubricated chain is
more likely to break and
lead to increased wear on
the bar, chain and drive
sprocket.
• Number of teeth on bar
tip sprocket (T).
Small number = small tip
radius = low-kickback
• Chain pitch (inches)
The spacing between the
drive links of the chain
must match the spacing of
the teeth on the bar tip
sprocket and drive
sprocket.
• Number of drive links
The number of drive links
is determined by the
length of the bar, the chain
pitch and the number of
teeth on the bar tip
sprocket.
• Bar groove width (inches/
mm)
The groove in the bar
must match the width of
the chain drive links.
• Saw chain oil hole and
hole for chain tensioner

WARNING!
!
The risk of kickback is increased with a
badly sharpened chain!
A.General information on sharpening
cutting teeth
• Never use a blunt chain. When the chain is blunt you have
to exert more pressure to force the bar through the wood
and the cuttings will be very small. If the chain is very blunt
it will not produce any cuttings at all, just wood powder.
• A sharp chain eats its way through the wood and produces
long, thick cuttings.
• The cutting part of the
chain is called the
CUTTING LINK and
this consists of a
CUTTING TOOTH
(A) and the RAKER LIP
(B). The cutting depth is
determined by the
difference in height
between the two.
• When you sharpen a
cutting tooth there are
five important
factors to remember:
A
B
It is very difficult to sharpen
a chain correctly without the
right equipment. We recommend you to use a file gauge.
This will help you obtain the
maximum kickback
reduction and cutting
performance from your
chain.
The following faults will increase the
!
risk of kickback considerably.
• FILE ANGLE TOO
LARGE
• CUTTING ANGLE TOO
SMALL
• FILE DIAMETER TOO

SAFETY INSTRUCTIONS
B. Sharpening
cutting tooth
To sharpen cutting teeth you
will need a ROUND FILE
and a FILE GAUGE.
1. Check that the chain is
correctly tensioned. A
slack chain is difficult to
sharpen correctly.
2. Always file cutting teeth
from the inside face,
reducing the pressure on
the return stroke.
File all the teeth on one
side first, then turn the
saw over and file the teeth
on the other side.
3. File all the teeth to the
same length. When the
length of the cutting teeth
is reduced to 4 mm (.16")
the chain is worn out and
should be replaced.
min 4 mm
(0,16")
C. General advice on setting raker
clearance
• When you sharpen the
cutting teeth you reduce
the RAKER
CLEARANCE (cutting
depth). To maintain
cutting performance
you must file back the
raker teeth to the
recommended height.
• On a low-kickback
cutting link the front
edge of the raker lip is
rounded. It is very
important that you
maintain this radius or
bevel when you adjust
the raker clearance.
• We recommend the use
of a raker gauge to
achieve the correct
clearance and bevel on
the raker lip.
!
WARNING!
The risk of kickback is increased if the
raker clearance is too large!
