Safety Instructions
The safety instructions must be observed when using the chainsaw. For your safety and the
safety of others, read this information carefully before using the chainsaw and keep it for
future reference. Only use the chainsaw for sawing trees or wooden objects. All other use of
the chainsaw is at your own risk and could be dangerous. The manufacturer will not be held
responsible for any damage caused by improper use.
Safety Instructions and the Prevention of Injury
To prevent the improper use of the chainsaw read the entire operating manual before you
begin using the chainsaw for the rst time. All information concerning use of the chainsaw is
relevant to your personal safety.
Let an expert show you how to use the chainsaw and protective equipment before you begin
using it for the rst time. Start by cutting timber on a saw horse to familiarise yourself with the
chainsaw before taking on more difcult tasks.
• Before connecting the chainsaw to the wall socket, inspect the mains lead and plug
for any damage. A damaged mains lead must be replaced immediately by a qualied
electrician.
• Never use the machine with a damaged mains lead, plug or extension lead that does not
meet current standards. Unplug the machine immediately if any part is damaged.
• Switch off the chainsaw and let the chain come to a complete stop before adjusting the
chain guard.

6
English
• Always use safety gloves and safety goggles when using the chainsaw.
• To minimise the risk of accidents, wear safety footwear and appropriate clothing that will
not get caught in the moving parts of the chainsaw.
• Use ear protection to protect your hearing. A helmet with ear defenders and visor is preferable.
• Make sure that you are standing steady and well balanced when using the chainsaw.
• Keep the work area clean and tidy.
• To prevent electric shock, avoid touching the earthed parts.
• Always unplug the chainsaw before cleaning or maintenance.
• Make sure that the power switch is set to OFF before plugging the machine into the
wall socket.
• The chainsaw should only be operated by one person at a time. Keep bystanders out of
the chainsaw’s risk zone; take extra care to ensure that children and animals maintain a
safe distance.
• Make sure that the saw chain is not in contact with any object before starting.
• Hold the chainsaw rmly in both hands when sawing.
• The chainsaw must not be used by minors, but persons aged 16 years or older may
use the chainsaw under adult supervision if it is a part of their education. Only lend the
chainsaw to people who have read the instruction manual and who know how to use a
chainsaw. The instruction manual should always accompany the chainsaw if lent out.
• Store the chainsaw in a locked room out of the reach of children.
• The chainsaw is only to be used by people in a good state of health. Never operate the
chainsaw when you are tired, drunk or under the inuence of medicine etc. Have a rest if
you feel tired whilst working.
• Do not expose the chainsaw to rain or moisture. Make sure that the work area is well lit.
Never use the chainsaw in environments containing ammable liquids or gases.
• Make sure that the chainsaw is unplugged and placed out of the reach of children or
bystanders, when taking a break.
• Always place the bark spike against the area to be sawed before starting to saw.
• Only remove the bar from the wood whilst the chain is still rotating.
• Never use the chainsaw whilst standing on a ladder, in a tree or anywhere incapable of
providing a steady platform. Never saw using one hand, always hold the saw in both hands.
• The mains lead and extension lead must always be behind the operator.
• The mains lead must always be trailed out behind the chainsaw.
• Use only original parts and accessories.
• Chainsaws used outdoors must be connected to a residual current device.
• Do not overload your tools. They work better and safer within the limits of their capacity.
• Always use tools that are the correct size. Do not use lower powered chainsaws for
heavy work.

• Use the mains lead only for the purpose for which it is intended. Do not carry the chainsaw
by its mains lead. Do not pull the mains lead, grip the plug when unplugging the chainsaw.
Keep the mains lead from heat, oil and sharp objects.
• Use only extension leads designed for outdoor use when using the chainsaw outdoors.
• Make sure that the stock has adequate support when sawing processed timber, thin
branches or logs (e.g a saw horse, see  g. a). Do not stack the timber, allow anyone else
to hold the timber or hold the timber with your foot whilst sawing it.
• Logs must be  rmly supported when you saw them.
• When working on steep hillsides, always cut from
the upper side of a fallen tree.
• When cross-cutting always rest the bark spike
against the timber (se  g. b).
• Always rest the bark spike against the timber before
sawing. Start the chainsaw and start sawing. Lift the
rear of the chainsaw and direct the chainsaw using
the front handle. Use the bark spike as a support. In
order to change position whilst cutting, stop cutting
and press lightly on the front handle. Withdraw the
saw bar slightly, reposition the bark spike deeper in
the cut and lift the rear handle upwards (see  g. b).
• Withdraw the bar from the cut in the timber whilst
the saw chain is still moving.
• If you saw more than one cut, switch the saw off
between cuts.
• Plunge sawing and horizontal sawing should only
be attempted by professionals due to the high risk
of kickback (see  g. c).
• When sawing horizontally, use the lowest possible
angle. Great care should be exercised, as the bark
spike cannot be used in this case.
• If the chain snags when sawing with the upper side
of the bar, the chain can be thrown towards you.
Therefore, you should saw using the underside of
the bar as much as possible, as the chain will be
thrown away from you (see  g. d & e).
• Be extra vigilant when sawing felled limbs. Sawn
offcuts can be thrown in different directions.
Risk of injury!

8
English
• Do not use the bar of the chainsaw for clearing away sawn off twigs.
• When sawing limbs off trees the chainsaw should be supported against the tree trunk if
possible. Do not saw using the end of the bar, because this creates a risk of kickback (see
g. c).
• Tree limbs should only be removed by trained experts. Risk for Injury!
• Be extra vigilant with limbs under tension. Do not remove hanging limbs from below.
• Never stand on the tree trunk when removing limbs.
• The chainsaw should not be used for forestry work, i.e. felling and removing limbs in the
forest. Owing to the fact that the chainsaw needs a supply of electricity, it does not have
the required mobility and its safety cannot be guaranteed.
• Watch out for falling trees and keep out of their way.
• When a tree is felled, watch out for falling branches when stepping backwards.
• On slopes, always stand next to or upslope of the trunk or log, never below it.
• Watch out for timber rolling towards you, the chainsaw could kickback.
• The chainsaw can kickback if the tip of the saw bar unintentionally comes into contact with
wood or other solid material. In this case the chainsaw could be thrown out of control at
high speed, posing a risk to the operator.
Follow these safety instructions to prevent the saw bar from kicking back
• Never start to saw with the tip of the bar.
• Never saw with the tip of the bar. Be careful when resuming work on previously started cuts.
• Always start the chainsaw so that the chain is moving before you start cutting.
• Keep the chainsaw sharp and correctly ground (use a le gauge if you can’t le freehand
or take the chain to professionals for sharpening).
• Never saw into more than one branch at a time, make sure that you do not saw more than
one branch at a time.
• When bucking, be careful when several tree trunks are lying close together. Use a saw
horse if possible.
Transporting and Handling the Chainsaw
Pull out the plug and cover the bar with the scabbard before transporting the chainsaw.
Switch the saw off when it has been lifted out of a cut, if you are going to make several cuts.

Preparations before starting
Make sure the power voltage indicated on the chain saw’s rating plate is the same as the
voltage at the power point. Always check before starting that the chainsaw is undamaged
and is safe to use. Also check that chain lubrication is functioning and that there is chain oil in
the tank (see g. 4). Rell chain oil as soon as the oil level has gone down to the MIN level.
When the oil level is above this level chain lubrication works well. Check chain lubrication as
follows: stop the chainsaw and hold the guide approximately 20 cm above a piece of wood or
other lightly coloured object. If lubrication is functioning properly, the oil will splash from the
chain and be seen on the lightly coloured object. If no traces of oil are seen you should clean
the outow hole (g. 2, C) and the upper tightening hole in the guide (Fig. 2, E), or contact the
retailer or service station for advice or servicing. (Read section ” relling of chain oil and chain
lubrication”). Check the tension of the chain and adjust when necessary (read section ”Chain
tightening”). Check that the kick back guard/chain brake is functioning (read section ”Reset
kickback guard/Chain brake).
Mounting of guide and saw chain
The plug must be removed from the socket.
Important: The kick back guard (3) to the chain brake must be in its rear setting (see g. 3).
The guide and chainsaw are not assembled on delivery. The chainsaw has a new type of set-
ting for chain tightening and locking of the saw guide consisting of two parts:
A. A combined tightening/locking wheel which is assembled on the chain hood.
The tightening/locking wheel consists of two different parts: a black central dial (5) for
locking the guide (and locking of the setting for chain tension) and an outer dial (16) for
setting the chain tension (see g. 4).
B. A tightening wheel for chain tightening is mounted on the guide.
The tightening wheel (19) is mounted on the guide with a screw (F) through the lower hole
and a guiding pin in the upper hole (D) on the guide (see g. 5).

7. Check the tightness of the chain: the saw chain should be able to be lifted approximately
5 mm in the middle of the guide when the tension of the chain is correct. Adjust when
necessary: Loosen the black centre dial on the tightening/locking wheel a little; adjust the
tension of the chain by turning the outer wheel; tighten the black centre dial to lock the
guide thus xing the chain’s set tension.
Fig. 6
Mount the saw guide and saw chain as follows
1. Turn the chain bar locking knob (5)
anticlockwise and remove the chain drive
gear cover (6).
2. Fit the chain onto the chain bar, making
sure that it is the right way round.
3. Pass the chain bar over the chain bar
bolt and point the bar with the chain on it
straight up.
4. Pass the chain over the drive gear.
5. Fold the chain bar back down, making sure
that the chain sits in the track of the bar and
on the teeth of the drive gear.
6. Now mount the chain drive (6) by inserting
the guage (M) on the rear edge of the hood
(L) in the saw and then fold the hood so that
the centre dial (5) rests against the guide
bolt (18). Turn the black centre dial (5)
clockwise so that it threads onto the guide
bolt. Now tighten the chain by turning the
outer dial clockwise (16). (The inner dial (5)
is only for locking the guide and the outer
dial (16) for tightening the chain).

Adjusting the chain tightness
1. Check the tension of the chain  rst: the saw chain should be able to be lifted.
approximately 5 mm in the middle of the guide when the tension of the chain is correct.
2. Loosen the black centre dial (5) on the tightening/locking wheel a little; adjust the tightness
of the chain by turning the outer wheel (16).
3. Tighten the black centre dial in order to lock the guide, thus  xing the set chain tension
(before tightening check that the saw chain is correctly positioned in the drive wheel and
sprocket around the entire guide).
Refilling the chain oil
Clean the oil lid before opening in order to prevent dirt getting into the oil tank. Unscrew the lid
and  ll with chain oil; the oil level can be seen in the oil tank (15) beneath the  lling hole. Fill
up, and then screw tightly so that it is secure. Wipe off any spills.
Fastening the extension cable to the chain saw
Only use extension cables intended for outdoor use (at least 1.5 mm², maximum of 75 metres
long). Fasten the extension cable around the rear handle as shown in the picture. If an exten-
sion cable is longer than 30 m is used, there may be voltage drop causing the chainsaw to
perform poorly.

Chain lubrication
The saw chain and saw guide must be lubricated during operation in order to avoid major
wear and tear. Chain lubrication is automatic. Never use the chainsaw without a functioning
lubrication. Both the saw guide and saw chain can be damaged very quickly without lubrica-
tion; that is why it is important to check the chain lubrication function and oil tank level with
every use (g. 7)
Never use a chainsaw if the oil level is under MIN.
• Min: When the oil level is under MIN or 5 mm at the lower part of the window in the oil
tank (15), ll up with chain oil.
• Max: Fill with chain oil until the whole window is full.
Checking chain lubrication
Check the lubrication of the chain as follows: start the chainsaw and hold the guide approxi-
mately 20 cm above a piece of wood or other lightly coloured object. If the lubrication is func-
tioning properly, the oil will splash from the chain and be seen on the lightly coloured object.
If no traces of oil are seen you should clean the outow hole (C) and the upper tension hole
in the guide (D), see g. 2, or contact the retailer or service station. Be careful not to allow the
chainsaw to touch the ground during testing.
Chain oil
The life expectancy of the chain guide and saw chain depends on which chain oil is used.
Only use chain oil and never spilloil etc. Use environmentally friendly types of chain oil, store
the chain oil in a container designed for chain oil.
Saw guide
The saw guide (7) wears down the most on the tip and on the underside; turn the guide, when
the chain is being sharpened so that it wears on both sides. File away eventual burrs on the
saw guide with a at le.
Chain drive
The chain drive (17) is subject to extreme wear; check for marks, wear or disgurement. Re-
place chain if required. Be warned, the chain drive will wear down a new saw chain quickly.
Contact the retailer service station to replace the chain drive.
Guide guard
Put back the guide guard straight away when you have nished sawing and always when the
chainsaw is to be stored or transported.
Kick back guard/chain brake
In the event of kick back from the saw guide the chain brake will be activated by the kick back
guard (3) by being pushed forward by the handle switching the motor off in 0.15 of a second (g. 3).
Fig. 8 1

English
Testing the kick back guard
Warning! The chain brake must be checked before every use.
Firmly hold the chainsaw with both hands. Start up and fold down the kick back guard (to “0”)
towards the chain brake with the handle; the saw chain should stop immediately.
Resetting the kick back guard/chain brake
The chain brake must be reset before the chainsaw can be started again: turn off the chain-
saw (release switch), push the kick back guard (3) back until it locks in its rear position (g. 3).
The chain break’s guard function has now been reset.
Sharpening of the saw chain
When the saw chain becomes blunt and no longer cuts efciently and safely, it must either be
replaced or sharpened (led).
Attention! It is easier to sharpen the saw chain with a kind of “ ling gauge” which can be
purchased at most hardware stores. Read the instructions for the ling gauge before use.
File the chain as follows:
• Pull the plug from the socket.
• Put on protective gloves.
• Check that the chain tension is adequate.
• Push be chain break’s trigger handle (kick back guard) forward in order to fasten the saw
chain to the guard.
• Use a Ø 4mm round le.
• File horizontally against the guide at an angle of 38° in the direction of the chain.
• File every cutting tip outwards/forwards in the direction of the chain.
• File every cutting tip evenly on each one so that the saw chain is symmetrically led
• Check the height of the depth gauges every fth le. If the depth gauges need ling a at
le is to be used and it is important that the original prole is maintained.
• Measure the height of the depth gauges (depth gauge setting) after ling, which can be
purchased at most hardware stores.

Begin using the chainsaw
Always use protective goggles/visors, hearing protection, protective gloves and
protective clothing with a saw guard.
Only use extension cables with suf cient conductor area intended for outdoor use (at least
1.5 mm², maximum of 75 metres long). The chainsaw is equipped with safety lock: safety lock
and power switch are on the rear handle (1). These must be pressed down at the same time
to start the chainsaw. The chainsaw must be held securely by both handles on starting.
If the motor does not start, the kick back guard/chain
brake must be reset: push back the kick back guard (3)
see: Chain brake, Reset chain brake ( g. 3)
The chainsaw starts immediately at full velocity.
Turn the chainsaw off as follows: release the safety
lock (13) and power switch (11), and the chainsaw will
stop after approximately one second. Some vibration is
quite normal and safe.
To always be followed after completed work: clean the
saw chain and saw guide and put back the guide guard.
Safety precautions for chainsaw
Never use the chainsaw in rain or when very damp.
Remove plug straight away if the extension cable is damaged; do not touch the cable,
only hold the plug! Never work using a damaged extension cable.
Check that the chainsaw is undamaged. Also check that the chainsaw’s guard and safety
settings are functioning or whether any other parts are damaged before using the saw. Make
sure that all movable parts are movable and are fully functional. All parts must be correctly
mounted and must meet all the requirements ensuring that the chainsaw will function without
risk to the user. Damaged safety components and other parts must be repaired or replaced
by a service technician, unless indicated otherwise in the manual.
To consider when working with the chainsaw:
Kick back with the guide:
Avoid risk of accident by never sawing using the tip of the guide. If you saw with the tip, the
guide may suddenly kick back upwards/backwards with great force.
Always use protective goggles/visors, hearing protection, protective gloves, protective clothing
and shoes with saw guards.
Make sure the wood you saw is held down  rmly. Keep it in place with some type of clamp
when needed (in particular this applies to round and straight pieces of wood that may begin to
rotate while sawing). This also allows the use of both hands which makes it easier and safer
to use the chainsaw.
Kick back with the guide causes the saw to kick back upwards/backwards uncontrollably with
great force. Kick back often leads to the saw chain becoming blunt and weak. A blunt saw
chain increases the risk of kick back. Never use the chainsaw over your shoulder.
The chain saw’s sharpening/ ling is a very important safety measure; an incorrectly sharp-
ened saw chain may make the saw chain dangerous and uncomfortable to use!

Tips on using chainsaw
Sawing firewood
Follow these safety rules when sawing  rewood: make sure the wood is safely positioned
so that it cannot slide/roll during sawing. Try to fasten smaller pieces of wood. Only use
the chainsaw for sawing wood. Make sure that no stones, nails or other objects that can be
thrown around or damage the saw chain are near the chainsaw during sawing. Do not allow
the saw chain to touch the ground, barbed wire etc when sawing. Make sure that the guide
does not get caught in twigs; only saw twigs, one at a time. Make sure you are standing
straight; wear protective shoes with slip-proof soles. The chainsaw should always be switched
off when being moved. Do not hold your hand over the switch enabling the saw to start up
involuntarily if you should trip over anything.
To remember
• The chainsaw must be started  rst so that the saw chain is in motion when the saw guide
is placed against the log.
• Start the chainsaw by pressing the power switch and safety lock on the rear handle (1).
These must be pressed at the same time in order to start the chainsaw.
• Place the lower part of the spike bar (10) on the wood and begin sawing. Pull back
the chainsaw a little and move it so that the wood is higher up on the spike bar and
continue sawing.
• Be careful when sawing wood that is cracked or split as sharp splinters may be thrown about.
Sawing clamped-down wood
Warning! Be careful when handling wood that has been clamped down.
Check the incline of the wood before you begin sawing. If you saw on the side of the log
which has pushing forces the saw may get stuck. If you saw on the side with the pulling
forces, the log may split.
The upper side is loaded with pulling forces
and the underside with pushing forces.
Warning: The wood will split when sawn.
The underside is loaded with pulling forces
and the upper side with pushing forces.
Warning: The wood will strike downwards
when sawn.

Warning: The tree trunks quickly strike up-
wards, with great force and twists when sawn.
The uprooted stump may tip backwards or
forwards. Be very careful in this event!
Both sides are loaded with pushing forces.
Warning: The tree trunks may shoot out
the side when sawn. Be very careful in this
event!
Fig. 13 Fig. 14
Tree felling
The chainsaw is not meant for tree felling but for sawing above all. On occasion, however, it may
be used for felling smaller trees. Ask somebody who is used to handling motor saws if you are the
slightest bit unsure as to how the chainsaw should be used or about its working methods.
Protective equipment should always be used when working in the woods: Helmets tted with
hearing protection, and visors, trousers with saw protection, boots or shoes with saw protec-
tion, and of course a “ First Aid kit”.
• Small trees can often be felled by sawing through almost the entire trunk and by pushing it
in the right direction with your hands or shoulder (do not saw the whole way through, save
part of the trunk to use as a hinge.)
• Large trees require an undercut; the undercut determines the tree’s direction of fall.
45°
A
B
Fig. 15
Warning! Always make sure that you have
an exit prepared. Remove objects in the way
such as bushes and twigs before felling be-
gins. The best retreat exit (A) is a diagonal
one backwards in the direction of the fall. (B)
(Fig 15)
Warning! Make sure you stand above the
tree if the ground leans during a tree felling,
as it is more likely that the tree will slide
downwards or roll downwards after felling.
Attention! The direction of the tree’s fall
(B) is determined by the undercut. Before
felling, check whether the tree is leaning in
any direction, or if the twigs are much larger
on one side of the tree so that the tree has a
natural direction of fall.

Warning! Never fell a tree by yourself if there is a risk of something being damaged such as
a house, enclosure etc. Ask the assistance of a professional. Never fell trees near electric
power lines or telephone lines. Check that there are no spectators or pets nearby before you
begin sawing; look up from time to time to check that nobody is entering the risk zone.
Normal tree felling consists of two stages of sawing: undercutting (C) and fell cutting (D).
Start with the upper undercut (C) on the side
of the tree turned in the direction of the fall
(E). Then perform the lower undercut hori-
zontally, so that it meets the upper undercut
(do not saw too far). The cuts should be
broad enough so that the tree may be guided
as much as possible during the fall.
Warning! Never walk in front of the tree
you have made a cut in!
Perform the felling (D) from the other side of
the tree and 3 to 5 cm above the lower cut.
NEVER saw through the remaining trunk completely. ALWAYS leave a stump (F), as it is the
stump that guides the tree during the fall. If the tree is sawn through completely you will lose
control over the direction of the fall, and the tree may fall in any direction. Insert a felling wed-
ge or break-iron in the felling cuts before sawing is complete. If you saw the entire felling cuts
before the felling wedge or break-iron have been positioned in the saw notch the tree may
lean backwards and clamp the guide. With the help of a felling wedge or break-iron, check
that there are no spectators or pets within the risk zone.
Warning! Check that that there are no spectators or pets within the risk zone before
you make your rst cut.
1. Use timber compasses from plastic or wood (A) in order to prevent the guide (B) getting
stuck in the saw cut (g. 17).
2. If the tree’s diameter is greater than the length of the guide, you will have to make two
cuts (g. 18)

Warning! When the felling cut (D) has been made and only the stump (F) remains, the
tree can begin to be felled. Otherwise, you must use a felling wedge or timber compass
in order to help you.
Remove the chainsaw and turn off the motor and take a few steps back diagonally along your
retreat exit keeping an eye on the tree as it falls (see g. 15).
Trimming
Trimming means sawing off twigs on a
tree that is lying on the ground. Begin
by sawing off the twigs highest up on
the tree. Stand on one side of the tree
trunk and trim on the other side of the
trunk (and that way you’ll have the tree
trunk as protection between you and
the chainsaw). Be careful when sawing
twigs that are fastened; they must be
sawn from the right side, otherwise the
guide will get stuck.
Warning! Never stand on the tree
trunk when trimming.

Sawing
When sawing, tree trunks lying on the ground are sawn to another length. Make sure that
you are standing steady and balanced. If the ground leans, you should stand above the trunk
when sawing. Preferably, the tree trunks should be leaning up against something so that they
are not directly lying on the ground, which would increase the likelihood of sawing into the
ground and blunting the saw chain. If the tree trunk is supported at both ends you must begin
by dividing it in the middle. Begin by sawing through half the log from above. Then make a
connecting cut underneath. Otherwise, the guide may get stuck. Make sure the saw chain
does not touch the ground.
1. A tree trunk that has support under the whole length: saw from above rst, then roll the
tree trunk and make a connecting cut from above (g. 22).
2. A tree trunk that is supported at one end (e.g. if the tree trunk is lying in a sawhorse): Saw
from underneath rst (one third of the diameter to avoid splitting) and make a connecting
cut from above.
3. A tree trunk, supported at both ends: saw from above rst (one third of the diameter to
avoid splitting) and make a connecting cut from underneath (g. 21).
Attention: the best way of sawing is with support, preferably using a sawhorse; unless it is
not possible, and the tree trunk can be held upright with something else. Make sure that the
tree trunk is lying securely so that it cannot roll or fall down.
