Safety
Warning: Readall safety information, warnings and instructions. Failure to read safety information,
warnings and instructions can lead to fire, property damage or serious personal injury.
Persons (including children) whose physical, sensory or mental capability or lack of experience and knowledge means that
they cannot use thesaw in asafe way must not use it without supervision or instruction. Children shall be supervised to
ensure that they do not play with thesaw.
1) Work area safety
a) Keep thework area clean and well illuminated. Cluttered and poorly lit areas invite accidents. Rags, clothing, cables,
gloves or other materials must not be left in theworkarea.
b) Do not use thesaw in explosive environments, such as in thepresence of flammable liquids, gases ordust.
Thesaw can create sparks which may ignite dust orfumes.
c) Keep children and bystanders away from thearea when you are using thesaw. Distractions can cause you to lose control.
2) Personal safety
a) Pay attention to what you are doing and use common sense when using thesaw. Neveruse thesaw if you are tired
or under theinfluence of drugs, alcohol or medication. Onemoment of inattention while using achainsaw may result in
serious injury.
b) Wear protective clothing. Always wear safety glasses. Usingprotective clothing such as dust masks, non-slip safety
shoes, helmets and ear defenders reduces therisk of injury.
c) Remove all service tools/keys before starting thechainsaw. Aspanner or other tool which has been left on arotating
part of thesaw could result in aninjury.
d) Do not overreach. Keepproper footing and balance at alltimes. This will allow you to have better control of thesaw
in unexpected situations.
e) Wear suitable clothing. Donot wear loose-fitting clothing or jewellery. Keephair, clothes and gloves away from
movingparts. Loose-fitting clothes, jewellery or long hair could become caught in movingparts.
3) Use and maintenance of thesaw
a) Do not force thesaw. Makesure that thesaw is designed for thework you are about to perform. Thesaw must only be
used as described in this instruction manual.
b) Do not use thesaw if thepower switch is not functioning properly. Anysaw that cannot be controlled by thepower
switch is dangerous and must be repaired.
c) Store chainsaws that are not being used out of children’sreach. Donot allow people who are unfamiliar
with chainsaws or these instructions to operatethem. Chainsaws can be dangerous if they fall into thehands of
inexperiencedusers.
d) Properly maintain thesaw. Checkfor misalignment, binding of moving parts, broken parts or anything else which
might affect theoperation of thesaw. Ifany damage is noticed, have thesaw repaired beforeusing. Manyaccidents are
caused by poorly maintainedsaws.
e) Keep thechain sharp andclean. Properly maintained chains with sharp edges are easier to control.
f) Use thesaw, and any accessories in accordance with these instructions, taking into account theworking conditions
and thework to be performed. Useof thesaw for apurpose other than that for which it is intended could result in
adangerous situation.
• Keep all parts of your body away from thesaw chain once thesaw has been started. Before starting thesaw,
check that thesaw chain is not in contact with any objects and can run freely. Evenabrief moment of inattention
can lead to thesaw chain fastening in anitem of clothing or abodypart.
• Always hold thesaw with your right hand on therear handle and your left hand on thefront handle. Neverhold
thesaw in any other way, it increases therisk of personal injury.

ENGLISH
• Use protective eyewear and hearing protection. Protective equipment for hands, head, legs and feet are also
recommended. Wearing thecorrect type of safety clothing reduces therisk of personal injury from thesaw chain or
flying debris from thesawing.
• Never climb atree to operate thechainsaw. Usingachainsaw in atree can result in personal injury.
• Make sure that you stand on afirm, level surface when you use thesaw. Slippery and unstable platforms such as
ladders can result in aloss of balance and loss of control over thesaw.
• Be prepared for branches under tension to spring back during thesawing process. Whenthetension in branches
isreleased they can spring back and strike chainsaw operators causing them to lose control of theirsaws.
• Be very careful when cutting brush and saplings. Thintwigs can get caught in thesaw chain and be projected
towards you or cause you to lose your balance.
• Always carry thechainsaw by thefront handle with theguide bar pointing away from yourbody. Thescabbard
must always be fitted when thechainsaw is being transported or stored. Usingthechainsaw correctly will reduce
thelikelihood of contact with thesaw chain when it is in motion.
• Follow theinstructions regarding lubrication, chain tensioning and changing of accessories. Animproperly
tensioned or lubricated chain increases therisk of chain breakage or kickback.
• Always keep thehandles dry, clean and free of oil and grease. Slippery handles covered in oil can cause you to lose
control over thesaw.
• Cut woodonly. Thesaw is not designed for sawing plastic, hardboard or other building materials not made
ofwood. Usingthesaw to saw amaterial it was not designed to saw could lead to adangerous situation.
Causes and prevention of kickback
Kickback can occur when thetip of theguide bar contacts anobject or if thesaw cut closes and traps thechain.
If thetip of theguide bar touches anobject it can cause areaction which throws theguide bar back up towards theoperator.
Pinching thesaw chain along thetop of theguide bar may push theguide bar rapidly back towards theoperator.
All of these reactions may cause you to lose control of thesaw which could result in serious personal injury.
Do not rely solely on thesafety features fitted to thesaw. Whenusing thesaw you yourself must take precautions to prevent
accidents and injuries. Kickback is caused either by poor maintenance, anincorrect sawing method or using thesaw for
thewrong purpose. Thiscan be avoided by following thefollowing safety precautions:
• If you understand what causes kickback therisk of being surprised and losing control will be reduced.
• Hold thesaw firmly with bothhands. Holdthesaw with your right hand on therear handle and your left hand on
thefront handle. Maintain afirm grip with thumbs and fingers encircling thehandles and your arms and body
positioned in such away that you can resist kickback forces should they occur. You can control theforces arising
from akickback if thecorrect precautions aretaken. Neverlet go of thesaw when theengine is running.
• Make sure that thework area is free of obstacles. Neverlet thetip of theguide bar contact atree trunk, branch or
other object.
• Always saw using full throttle.
• Do not overreach and do not saw above shoulder height. Thiswill help you to prevent thetip of theguide bar from
accidentally coming into contact with objects and and cause you to lose control over thesaw if something unexpected should
happen.
• Follow themanufacturer’s instructions regarding sharpening and maintenance of thesawchain. Ablunt chain also
increases thelikelihood of kickback.
• Use only those replacement parts, guide bar and saw chain recommended by themanufacturer. Usingaguide bar
or saw chain of theincorrect type can lead to kickback or chain breakage.
WARNING: BEWARE OF KICKBACK!
Warning: Kickback poses aserious accident risk and can cause theoperator to lose control of thesaw.
Thiscan result in serious injury to theoperator and any bystanders. Bevigilant at alltimes.
Kickback caused by thenose or tip of theguide bar touching anobject or by thewood closing
and pinching thesaw chain in thecut is themain cause of chainsaw accidents.

General safety rules
• Never use thesaw when you are tired, sick, under theinfluence of alcohol or medicine.
• Local regulations may restrict theage of theoperator; check what minimum operator age requirements apply to your region.
• Always be careful when handlingfuel. Wipeoff any spilt fuel and move thesaw at least 3 metres away from therefuelling
location before startingit.
• Remove any sources of ignition and see that there are no sparks, naked flames, lit cigarettes,etc. inthearea where
thefuel is mixed, used or stored.
• Never smoke when refuelling or operating thesaw.
• Do not permit anyone other than theoperator to come close to thesaw when it is being started orused. Children, pets
and onlookers should be kept at least 10 metres away from thesaw when it is being started orused.
• Never begin using thesaw without having full view of theentire workarea. Keepyour proper footing and balance and
make sure that you have aplanned retreat path to asafe place away from thefallingtree.
• Never work alone, always have aperson close by whom you can call if you needhelp.
• Never work in poor light conditions, heavy rain or strongwind.
• Thesaw must only be used for cutting natural untreatedwood.
• Never use thechainsaw on treatedwood.
• Thesaw must not be used for clearingbrush.
• Make sure that thesaw chain is not in contact with any object before starting.
• Always carry thechainsaw with theengine shut off, theguide bar to therear and thesilencer pointing away from thebody.
• Always inspect thesaw before startingit. Donot start it if there are worn, missing or damagedparts. Neveruse thesaw
if it is damaged, incorrectly adjusted or incorrectly assembled. Whentheengine has started: Checkthat thechain saw
stops completely when you let go of thethrottle.
• Any service of thesaw other than that mentioned in this instruction manual should be carried out by qualified service personnel.
• Always shut off theengine before placing thesaw on theground.
• Use extreme caution when cutting brush and saplings because slender material may fasten in thesaw chain and be
whipped towards you or pull you off balance. Becareful when cutting limbs under tension. Guardagainst falling branches
and be alert for springback and pinching of theguide bar when thetension in thefibres of thewood is released.
• Keep thehandles dry, clean and free of oil and fuel mixture.
• Operate thechainsaw only in well-ventilatedareas.
• Never operate thesaw in atree unless you have been specially trained for suchwork.
• Never transport thesaw without thescabbard fitted.
• Never operate thesaw close to flammable liquids or gases, doing so poses arisk of fire or explosion.
• Never refuel, top up theoil or perform any maintenance to thesaw when theengine is running.
• First-time users should be equipped with safety equipment and be instructed in thecorrect use of thechainsaw by
anexperienced operator.
• Never start thesaw indoors. Thesaw will emit poisonous exhaust gases as soon as it is started, these gases may be
invisible and odourless but are harmful if inhaled. Beaware that thesaw will produce harmful sawdust and oil mist from
chain lubrication, protect yourself accordingly.
• Always wear gloves and keep your hands warm when using theproduct. Long-term exposure to hand-arm vibration from
using achainsaw can lead to permanent damage to hands andarms. Ifyou experience symptoms such as poor blood
circulation, white finger tips, reduction in sense of touch, numbness or tingling in fingers, contact adoctor.
• Drive in thespiked bumper directly behind theintended cut and let this be thehinge around which thesaw pivots.

Fitting the guide bar and saw chain
Note: Onlyuse a14″(35cm) bar and 52-link 3/8″chain.
Warning:
• Thesaw chain is verysharp. Wearprotective gloves.
• Only use theincluded guide bar or one recommended by themanufacturer. Useof other types of guide bar can lead to
personal injury or damage to theproduct.
1. Remove thecover (7) over thedrive sprocket and clutch by first removing thetwo retainingnuts.
2. Place theguide bar over thetwo bolts and slide it
towards thedrive sprocket.
4. Move theguide bar so that thechain tensioner is in its
hole in thebar.
6. Turn thechain by hand so that you can feel that it runs
freely and is sitting correctly on thedrive sprocket.
3. Place thesaw chain around thedrive sprocket (25)
and into thegroove in theguide bar with thelinks
pointing in thedirection shown on theguidebar.
5. Refit thecover, hand-tighten thenuts enough for thecover
to hold theguide bar inplace. Ifyou tighten thenuts too
much you won’t be able to tension thechain.
7. Tension thechain by turning theadjuster screw
clockwise. Tension thechain until it can be lifted no
more than 5mm from theguidebar.
8. Tighten thetwo retaining nuts (to atorque of 12–15Nm).

Fuel and lubrication
Petrol
• Warning: Neverrefuel thesaw while theengine is running.
• Let theengine cool for afew minutes before beginning to refuel.
• Use aready-mixed mixture of environmentally-friendly petrol (alkylate petrol) and 2%oil.
• Wipe off any spilt fuel and move thesaw at least 3 metres away from therefuelling location before startingit.
Note: Always refuel outdoors, never indoors.
1. Lay thesaw on its side, remove thefuel cap and pour in fuel until thetank is roughly 80%full.
2. Wipe up any fuel spills immediately.
3. Screw thefiller cap backon.
Chain oil
Warning: Neverstart thechainsaw without first filling thechain oil reservoir. Usingthesaw without chain oil will soon wear
out both thechain and theguidebar.
1. Lay thesaw on its side, remove theoil filler cap and pour in oil until thereservoir is roughly 80%full.
2. Wipe up any spills immediately.
3. Screw thefiller cap backon.
Chain brake
Thesaw is equipped with anautomatic chain brake which stops thesaw chain in theevent of kickback. Thechain brake is
activated by theinertial forces triggered by thekickback itself. Thechain brake can also be activated manually by pushing
thelever (2) forward towards thechain. Thebrake lever should click into position.
If thechain brake is activated, pull thehandle back towards thesaw again until it clicks and thebrake is disengaged.
Warning: Always check thechain brake before starting thesaw.
What todo:
1. Hold thesaw horizontal over atree stump or similar. Holdtherear handle and
let go of thefront handle so that theguide bar bumps against thetreestump.
Thechain brake should engage automatically. Contact theretailer for reparation if
thechain brake does not activate.
2. In theevent of akickback and thechain brake activates while you are working,
it is important that you release thethrottle immediately. Running theengine at
high speed with thechain brake activated will damage theclutch.
Starting the engine
Warning: Checkthat thesaw is intact and that theguide bar and chain are correctly fitted before startingit. Thesaw must
never be started if thechain or guide bar is damaged in anyway.
Cold start
1. Activate thechainbrake.
2. Pull thechoke control all theway out, this activates thechoke plate and supplies starting fuel to facilitate ignition.
3. Place thechainsaw securely on theground. Placeone foot on therear handle and hold thefront handle with onehand.
4. Pull firmly on thestarter handle with your otherhand. Whentheengine has fired once, push thechoke control all
thewayin. Thechoke is now disengaged but alittle starting fuel iskept.
5. Firmly pull thestarter handle until theengine starts. Theengine is now running on starting fuel, squeeze thethrottle once
to disengage thestartingfuel.
Warm start
1. Activate thechainbrake.
2. To activate thestarting fuel only, first pull thechoke control all theway out and then push it all theway backin.
Thiswill help to start theengine.
3. Place thechainsaw securely on theground. Placeone foot on therear handle and hold thefront handle with onehand.
4. Pull firmly on thestarter handle with your other hand until theengine starts. Theengine is now running on starting fuel,
squeeze thethrottle once to disengage thestartingfuel.

Check the chain lubrication
Warning! The guide bar, saw chain and drive sprocket should always be
assembled while checking the chain lubrication. If you start without these being
assembled you can be injured by rotating parts or by the centrifugal clutch’s
weights. It is very dangerous to start the chain saw if all the parts are not mounted.
Start the engine and let it run on medium speed. Keep the guide bar with the saw chain
close to the ground or an object. If the chain lubrication is working a small amount of oil
should spatter in front of and under the guide bar.
Switching off
1. Release thethrottle.
2. Turn thepower switch to 0.
Tips for using the chainsaw
Chopping rewood
Safety rules:
• Make sure that thelog is secure and not able to slide/roll around during sawing. Try to fasten small logs before starting to
cut them.
• Only use thechainsaw for cutting wood. Make sure that no stones, nails or other objects that can be projected or
damage thechain are close to thechainsaw during use. Avoid letting thechainsaw come into contact with theground,
barbed wire fences, etc, during operation.
• Make sure that thetip of theguide bar does not come into contact with small branches, chop one branch/twig at atime.
Make sure you have asteady stance, use safety footwear with non-slip soles.
• Thechainsaw must always be switched off when you move around. Do not keep your hand on thepower trigger so that
thesaw can start if you trip over something.
Remember
• Thechainsaw must always be started first and running at full speed before thesaw chain is pressed against thewood.
• Start thesaw by pressing in thelock-off switch and squeezing thetrigger on therear handle (16).
• Place thelower part of thespiked bumper (21) against thewood and begin sawing. Pull thechainsaw backwards alittle
and move it so that thewood is higher up on thespiked bumper and continue sawing.
• Be careful when sawing wood that is split or cracked, splinters might be ejected.
Sawing trees that are under tension or compression
Warning: Be careful when cutting branches that are under tension or compression.
Size up thejob and work out how thetree or branch is bowed before starting to saw. If you saw into wood that is under compression,
thesaw could get stuck; if you saw into wood that is under tension, thewood could split and spring back unexpectedly.
