Always hold the chainsaw back handle with your right hand and the front handle with your left hand. Hold
the chainsaw by inverting your hands increases the risk of personal injury and should never be used.
For the chainsaw designed with the chain guide on the left side, the reference to the "right hand" and "left
hand" positions is reversed.
When cutting a branch that is under stress, pay attention to the risk of elastic return.
When the tension of the wood fibres is released, the spring-loaded limb may strike the operator and / or
project the chain saw out of control.
Exercise extreme caution when cutting brush and young shrubs. Fine materials can grip the cutting chain
and be thrown as a whip in your direction, or you lose balance under the effect of traction.
Follow the instructions for lubrication, tension and chain change accessories. A chain whose tension and
lubrication are incorrect can either break or increase the risk of rebound.
Keep handles dry, clean and free of oil and grease. Oily, greasy grips are slippery and cause loss of
control.

Be careful when using the machine during stormy weather. Do not use the machine during lightning,
thunderstorms or in bad weather in general.
There is advantage of using the provided spiked bumper when cutting trees and thick branches.
Perform regular functional check of the clutch. It should be no have chain movement at idling speed.
When operating the tool, be careful of the emission of exhaust gases, lubrication oil mist and saw dust;
avoid being exposed to these and wear protective equipment.
Wear protective gloves when assembly, disassembly, sharpening chain tensioning and when handling the
guide bar.
Guide-bar and chain adjustments shall be performed with the engine stopped.
Regularly check and test the chain brake.
Hazards may be encountered while using the saw, such as blockage of the saw chain. In order to reduce
hazards, follow the instruction for cutting operation; always check the condition of the tool. Do not start the
chainsaw directly in a tree.
1.2 FUEL HANDLING
Be very careful when handling fuels. They are flammable and the vapors are explosive.
Use only an approved container.
Never remove the fuel cap or add fuel while the machine is on. Turn off the unit and allow the engine and
exhaust components to cool before refuelling.
Do not smoke.
Never refuel inside a room
Never store the tool and the fuel tray indoors where there is a naked flame, such as near a water heater.
If fuel has spilled, do not attempt to start the machine, but rather move it away from the spill before starting
to use it. Clean any spills.
Replace and tighten the fuel tank cap after refuelling.
Follow the instructions in this manual for filling the tool with fuel.
1.3 MAINTENANCE AND STORAGE
Stop the tool and wait until it stops. Make sure all moving parts have come to a standstill.
Allow the machine to cool before performing inspection, adjustments, maintenance, servicing and storage.
Store the tool where fuel vapor will not reach a flame or spark.
When transporting and storing, always place the tool in its transport guard and protective device on it.
1.4 CAUSES OF REBOUNDS AND PREVENTION BY THE
OPERATOR
Bounce may occur when the spout or end of the chain guide touches an object, or when the wood tightens
and pinches the cutting chain in the cutting section.
The contact of the tip may in some cases cause a sudden reverse reaction by bouncing the chain guide up
and back towards the operator.
Pinching of the cutting chain on the upper part of the chain guide can force the chain guide to the operator
abruptly.
Either of these reactions can result in loss of control of the saw likely to result in a serious personal injury.
Do not rely exclusively on safety devices built into your saw. As a chain saw user, all measures should be
taken to eliminate the risk of accident or injury during cutting.
Bounce results from improper use of the tool and / or incorrect operating procedures or conditions and can
be avoided by taking the appropriate precautions specified below:
- Hold the saw with both hands firmly with the thumbs and fingers encircling the handles of the saw and
place your body and arms to allow you to withstand the rebound forces. The rebound forces can be
controlled by the operator, if appropriate precautions are taken. Do not allow chain saw to start.
- Do not stretch the arm too far and do not cut above the shoulder height. This helps prevent
unintentional end contacts and allows better control of the chain saw in unforeseen situations.
- Use only the manufacturers specified replacement guides and chains. Incorrect replacement guides
and chains may cause chain breakage and / or rebound.
- Follow manufacturer's instructions for sharpening and servicing the chain saw. A decrease in the depth
gauge level can lead to an increase in rebounds.

wear hearing protection and limit the operating time.
•Cuts if no suitable protective equipment is worn.
•Inhalation of particles and exhaust gases if no protective mask is worn.
•Risk of bodily injury and material damage resulting from flying objects.
•Prolonged use of this product exposes the operator to vibration and may produce “white finger” disease.
In order to reduce the risk, please wear gloves and keep your hands warm. If any of the symptoms of
"white finger" syndrome appear, seek medical attention immediately. Symptoms of "white finger" include:
- Numbness, loss of sensitivity, tickling, tingling,
- Pain, loss of strength, changes in colour or condition of the skin.
These symptoms usually appear on the fingers, hands, or wrists. The increased risk during cold weather.
1.6 REFUELLING
1) Turn off the engine before refueling. Always open the fuel tank cap carefully so that the existing pressure
can be released slowly.
2) High temperatures are generated on the machine body during use. Before refueling, allow the machine to
cool completely. If the machine has not cooled sufficiently, fuel can ignite during refueling and cause
severe burns.
3) Make sure the tank is not overfilled. If you spill any fuel, it should be wiped up immediately and the
machine cleaned.
4) Always properly close the threaded cap on the fuel tank, in order to avoid loosening of vibrations during
operation. Never refuel the machine near an open flame.
1.7 SAFETY FUNCTIONS OF THE CHAINSAW
SAW CHAIN WITH LOW KICKBACK
helps significantly reduce kickback, or the intensity of kickback, due to specially designed depth gauges and
guard links.
CHAIN BRAKE LEVER / FRONT HAND GUARD
protects the operator’s left hand in the event it slips off the front handle while saw is running.
CHAIN BRAKE
is a safety feature designed to reduce the possibility of injury due to kickback by stopping a moving saw chain
in milliseconds. It is activated by the CHAIN BRAKE LEVER.
SAFETY LOCK
prevents accidental acceleration of the engine. Throttle lever (7) cannot be squeezed unless the safety latch is
depressed.
STOP SWITCH
immediately stops the engine when actuated. Stop switch must be pushed to position “I” to start or restart the
engine.
CHAIN GUARD
fitted when the engine is stopped, prevents the danger of cutting injury from the chain teeth.
CHAIN CATCHER
reduces the danger of injury in the event saw chain breaks or derails during operation. The chain catcher is
designed to intercept a whipping chain.
Familiarise yourself with the saw and its components.

6.1 ASSEMBLY OF THE CHAIN BAR AND CHAIN TO THE ENGINE
UNIT
Do not start the engine until the saw is fully assembled.
Always wear protective gloves when handling the chain.
1) Remove the side cover (Fig. 2)
a) Make sure the chain brake lever / front hand guard (3) is pulled back into the DISENGAGED position.
b) Remove the bar mounting nuts (11) with the spark plug spanner (19).
c) Pull the whole side cover (A) from the engine.
2) Fit the chain bar (Fig. 2 / 3)
To ensure that the bar and the chain are supplied with oil, USE ONLY THE ORIGINAL BAR. The oiling
hole (C) must be kept clear of dirt and any build-up of residue.
a) Make sure the chain brake lever / front hand guard (3) is pulled back into the DISENGAGED position.
b) Fit the open end of the chain bar (1) over the bar pins (D).
3) To install the saw chain (Fig. 2 / 3 / 4)
a) Spread the saw chain (2) out in a loop with the cutting edges pointing CLOCKWISE around the loop.
b) Slip the saw chain (2) around the sprocket behind the clutch as shown in figure 3. Make sure the links
fit between the sprocket teeth.
c) Guide the drive links into the groove and around the end of the chain bar (1).
The saw chain may droop slightly on the lower part of bar.
This is normal.
•Pull the chain bar (1) forward until the saw chain (2) is closely seated. Make sure that all the drive links
are in the groove of the chain bar (1).
•Align the pin (F) at the inner side of the side cover (A) such that the fits into the hole of the chain bar (E).
•Turn the bar fastening pin (B) clockwise with the spark plug spanner (19). The saw chain (2) is not
allowed to slip off the chain bar (1) when you do this. Only loosely tighten the bar fastening pin (B) at this
stage and then follow the instructions for adjusting the chain tension as described in the section.
4) Adjusting the chain tension
The correct tension of the saw chain is extremely important and must be checked before starting and
periodically during all sawing work. If you take time to adjust the saw chain correctly, you will be able to make
better cuts and the life of the chain will be prolonged.
a) Hold the tip of the chain bar (1) upwards and turn the bar fastening pin (Fig. 2/ pos. B) with the spark plug
spanner (19) in a CLOCKWISE DIRECTION in order to increase the chain tension. If you turn the bar
fastening pin (Fig. 2/pos. B) in an ANTI-CLOCKWISE DIRECTION, the chain tension will be reduced.
Check that the chain is seated around the entire chain bar (Fig. 5/pos. X3).
b) After making the adjustment and with the tip of the bar still upwards, tighten the bar fastening pin (Fig.
2/pos. B). The chain is correctly tensioned when it is closely seated and can be pulled right around by
hand, when the chain brake lever (3) is released.
Always wear high-strength gloves when handling or adjusting the saw chain.
If the chain is hard to turn around the chain bar or jammed, it is too tightly tensioned. Make the following small
adjustments:
•Undo the bar fastening pin (Fig. 2/pos. B) by 1/2 of a turn ANTI-CLOCKWISE. Then slacken the chain
tension by slowly turning the bar fastening pin (Fig. 2/pos. B) in an ANTI-CLOCKWISE DIRECTION and
then pull the saw chain (2) back and forth on the chain bar (1) (Fig. 6). Continue until the chain can be
15

moved smoothly but is still closely seated (Fig. 5/pos. X2). Increase the tension by turning the bar
fastening pin (Fig. 2/pos. B) in a CLOCKWISE DIRECTION.
•When the saw chain is correctly tensioned, hold the tip of the bar upwards and completely tighten the bar
fastening pin (Fig. 2/pos. B).
•Secure the side cover (A) with the bar mounting nuts (11), by using the spark plug spanner (19) (Fig. 7).
•A new saw chain stretches, requiring adjustment after as few as 5 cuts. This is normal with a new chain,
and the interval between future adjustments will lengthen quickly.
•If the saw chain is TOO LOOSE or TOO TAUT, the drive wheel, chain bar, saw chain and crank shaft
bearing will suffer premature wear. Fig. 5/pos. X2 shows the correct tension (when cold) and Fig. 5/pos.
X3 shows the tension (when warm). Fig. 5/pos. X1 shows a chain that is too loose.
5) Chain brake mechanical test
Your chainsaw is equipped with a chain brake that reduces the possibility of injury due to kickback. The chain
brake is activated if pressure is applied against the chain brake lever (3) when, as in the event of kickback, the
operator’s hand strikes the lever. When the chain brake is actuated, saw chain movement stops abruptly.
The purpose of the chain brake is to reduce the possibility of injury due to kickback; however, it cannot provide
the intended measure of protection if the chainsaw is operated carelessly. Always test the chain brake before
using your saw and periodically while on the job. (See below for details of how to perform a test of the chain
brake).
6) To test chain brake (Fig. 8)
a) The chain brake is DISENGAGED (chain can move) when the CHAIN BRAKE LEVER (3) IS PULLED
BACK AND LOCKED (pos.1).
b) The chain brake is ENGAGED (the chain is locked) when the chain brake lever (3) is pulled forward (pos.
2). It should not be possible to move the saw chain.
The chain brake lever (3) should snap into both positions. If strong resistance is felt, or the lever does not
move into either position, do not use your chainsaw. Take it immediately to a professional Service Centre for
repair.
6.2 FILLING/CHECKING THE LUBRICATING OIL (FIG. 9)

2) Filling/Checking the fuel (Fig. 11)
Always switch off the engine before fueling. Never add fuel to a machine with a running or hot engine. Only
add fuel outdoors. If the engine is hot, allow to cool for at least five minutes before adding fuel. Move at least 3
m from refueling site before starting the engine. Do not smoke and stay away from open flames and sparks.
Failure to follow these instructions could result in a fire and cause serious personal injury.
a) Position the unit in a way that the fuel tank (10) faces upwards.
b) Remove the fuel tank cap
c) Refill with unleaded fuel carefully without overfilling. Leave approx. 5 mm space between the top of the
fuel and the inside edge of the tank to allow for expansion.
d) Tighten the fuel tank cap firmly.
e) Wipe up any spilled fuel.
It is normal for the engine to emit smoke during and after the first use.
If the cutting attachment still rotates in idle speed, contact Authorized Service Centers for correct idle speed
adjustment.
When the engine is idling the cutting attachment must not rotate under any circumstances!
6.3 OPERATION
Please note that the statutory regulations governing noise abatement may differ from one location to another.
a) Each time before use, check the following:
That there are no leaks in the fuel system.
That the equipment is in perfect condition and that the safety devices and cutting devices are
complete.
That all screws are securely fastened.
That all moving parts move smoothly.
b) Starting the engine when cold (Fig. 12 / 13)
Activate the chain brake lever (3) before starting.
Switch the stop switch (14) to ‘I’ (ON).
Pull the choke (9) fully out until it locks.
Push the fuel pump ‘primer bubble’ (8) 6-8 times.
Place the chainsaw on a firm, flat surface. Hold the chainsaw firmly as shown. Pull the starter handle
(16) rapidly 2 times. Beware of moving chain!
Push in the choke (9) as far as it will go.
Hold the saw firmly and pull the starter handle (16) rapidly 4 times. Engine should start.
Never allow the starter handle (16) to snap back when it has been pulled out. This may result in damage.
Always pull the starter handle (16) slowly (until you feel the initial resistance) before pulling it quickly to start
the engine.
Do not allow the starter handle (16) to whip back of its own accord.
If the engine does not start up even after several attempts, read the section ‘Troubleshooting’.
Always pull out the starter handle (16) in a straight line. If it is pulled out at an angle, friction will occur on the
eyelet.
As a result of this friction, the starter handle (16) will become frayed and will wear away faster. Always hold
the starter handle (16) when the starter line retracts.

moving chain!
•Pull the starter handle (16) rapidly 4 times. The engine should start. If the chainsaw does not
start after 4 tugs, repeat the steps of the procedure for starting the engine from cold.
Each time before use, check the following:
- That there are no leaks in the fuel system.
d) Switching off the engine (Fig. 12)
Emergency Stop procedure:
To stop the engine in an emergency, activate the chain brake lever / front hand guard (3). This will
immediately stop the chain. Then push the stop switch (14).
e) Normal procedure:
Let go of the throttle lever (7) and wait until the engine has changed to idling speed. Then set the stop switch
(14) to ‘0’ Stop.
Practice all the work steps with the engine switched off before you start to use the chainsaw.
When idling, the saw chain (2) should not move. If the saw chain (2) moves, you need to adjust the idling
speed!
6.4 OPERATING INSTRUCTIONS
a) Beware of the following:
•Rotary recoil (Fig. 14)
A = Recoil distance / B = Recoil reaction zone
•Impact/Jamming recoil and pulling reactions (Fig. 15)
A = Pull / B = Solid objects / C = Push
•To prevent pulling reactions, place the wood you wish to cut against the spiked bumper (12). Use the
spiked bumper as a pivot point during cutting.
•Make sure that the chainsaw cannot swing through at the end of the cut due to its own weight. If it is no
longer supported in the cut, hold something appropriate against it.
b) Important notices
•Turn off the engine if the saw comes in contact with foreign objects. Check the saw and, if applicable,
repair it.
•Protect the chain from dirt and sand. Even small quantities of dirt can quickly make the chain blunt and
increase the risk of kickback.
•Start by cutting up smaller logs to practise in order to get a feel for the device, before attempting difficult
tasks.
•Activate the throttle at maximum, before starting sawing.
•Press the casing of the chainsaw against the log when starting sawing.
•Run the device at full throttle throughout the whole sawing process.
•Let the saw do the work. Only use slight downwards pressure.
•Release the throttle as soon as you have finished your work, so the motor runs idle. If you let the machine
run at full throttle without load, there will be unnecessary wear and tear.
•So that you do not lose control of the device after the chain exits the wood, you should not apply any
pressure to the saw towards the end of the cut.
•Turn off the device before putting it down.
•Check after starting the idle setting. The cutting blade must be stationary during idling.
c) Felling trees - only with relevant training
18

Watch out for broken or dead branches which may fall during sawing and which could cause severe injuries.
Do not saw close to buildings or power lines if you do not know in which direction the felled tree will fall. Do
not work at night because you can see less well, or during rain, snow and storms because the direction in
which the tree will fall cannot be anticipated.
•Plan your work with the chainsaw in advance.
•The working environment around the tree should be cleared so you have secure footing.
•The machine operator should always be positioned at a higher level in the working area because the tree
will probably roll or slide down after felling.
d) The following conditions can influence the tree ‘s falling direction:
•Wind direction and speed
•Leaning of the tree - The leaning direction cannot always be recognised because of uneven or sloping
ground. Determine the leaning direction of the tree using a plumb line or a level.
•Branches growing (and therefore weight) only on one side
•Surrounding trees or obstacles
Look out for destroyed or decayed parts of the tree. If the trunk is decayed, it can suddenly break and fall
on you. Make sure there is enough space for the falling tree.
Keep a distance of 2½ tree lengths to the next person or other objects. The sound of the motor can drown out
warning cries.
Remove dirt, stones, loose bark, nails, brackets and wire from the sawing area.
Ensure you have a free escape route (Fig. 16)
Position 1: Escape route
Position 2: Falling direction of the tree
e) Felling of large trees (from 15 cm diameter) - only with relevant training
The undercutting method is used for felling large trees. For this, a wedge is cut out from the side of the tree
according to the required falling direction. After the dropping cut has been made on the other side of the tree,
it will fall in the direction of the wedge cut.
If the tree has large prop/buttress roots, these should be removed before the wedge is cut. If the saw is
used for removing the prop/buttress roots, the saw-chain should not touch the ground, so the chain does
not become blunt.
f) Undercut and felling the tree (Fig. 17 / 18)
•For the undercut, first cut the upper part (Pos. 1) of the wedge (Pos. 2). Cut 1/3 of the way into the tree.
Then saw the lower part (Pos. 3) of the wedge (Pos. 2). Now remove the wedge you have cut out.
•Afterwards, you can carry out the dropping cut on the opposite side of the tree (Pos. 4). For this, start
about 5 cm above the middle of the cut. In this way, there is enough wood between the dropping cut (Pos.
4) and the wedge (Pos. 2) so that it functions as a hinge. This hinge is designed to guide the tree in the
right direction when falling.
Before completing the dropping cut, if required, increase the cut using wedges to control the direction of the
fall. Exclusively use wood or plastic wedges. Steel or iron wedges can cause kickback and damage to the
device.
•Be aware of signs that the tree is beginning to fall: Cracking sounds, the dropping cut opening or
movement in the upper branches.
•When the tree begins to fall, stop the saw, put it down and leave immediately via your escape route.
•To prevent injuries, do not cut partly felled trees with your saw. Beware especially of partly felled trees
which are not supported. If a tree does not fall completely, remove the saw and help the process along
with a cable winch, a pulley or a towing vehicle.
g) Sawing a felled tree (log division)
The term “log division “describe the cutting up of a felled tree into logs of the desired length.
19

Do not stand on the log you are currently cutting. The log could roll away and you may lose your footing and
control of the device. Do not carry out sawing work on sloping ground.
h) Important notices
•Only ever saw one log or branch.
•Be careful when cutting split wood. You may be hit by sharp pieces of wood.
•Cut small logs or branches on a sawhorse. When cutting logs, no other person must hold on to the log.
Do not secure the log with your leg or foot.
•Do not use the saw in areas where logs, roots and other parts of the tree are entangled. Pull the logs to a
free area and cut the freed logs first.
i) Different cuts for log division (Fig. 19)
If the saw is jammed in a log, do not pull it out with force. You may lose control of the device and suffer severe
injuries and/or damage the saw.
Stop the saw and drive a plastic or wooden wedge into the cut until the saw can be pulled out easily. Restart
the saw and carefully continue with the cut. Never start the saw when it is jammed in a log.
j) Topping (Fig. 20, Pos. 1)
Topping starts at the upper side of the log where you hold the saw against the log.
Only use slight downwards pressure for topping.
k) Undercut (Fig. 20, Pos. 2)
Start the undercut on the underside of the log and hold the top edge of the saw against the log. Only use slight
upwards pressure for the undercut. Hold the saw securely to control the device. The saw will push backwards
(in your direction).
Never hold the saw the wrong way around for an undercut. You do not have control of the device in this
position. Always make the first cut on the compression side of the log. The compression side of the log is
where the pressure of the log ‘s weight is concentrated.
l) Log division without supports (Fig. 21)
•Using topping (Pos. 1), saw 1/3 of the way into the log.
•Turn the log around and make a second top cut (Pos. 2).
•When sawing on the compression side, make sure the saw does not get jammed. See Figure for cuts in
logs on the compression side.
m) Log division with log or support (Fig. 22-23)
• Always remember to make the first cut (Pos. 1) on the loaded side of the log.
• Cut 1/3 into the log for this.
• Make a second cut (Pos. 2).
n) Trimming and pruning
Always be careful and protect yourself from kickback. Never let the moving chain at the tip of the chain guide
come in contact with other branches or objects during trimming or cutting branches. Such contact can lead to
serious injuries.
Never climb into the tree for trimming or pruning. Do not stand on ladders, platforms etc. You could lose your
balance and control of the device.
