NOTE Special instructions for ease of under- standing and handling. 2 PRODUCT DESCRIPTION These operating instructions describe a hand-op- erated chain saw that is powered by a petrol en- gine.

The chain saw is exclusively designed for domes- tic gardening applications. In this application area the chain saw can be used for wood sawing work, e.g. for:

Sawing of tree trunks

Sawing of squared timbers

Sawing of branches, depending on the length of cut The chain saw must only be used outdoors for working with wood. While in use, it is necessary to wear adequate personal protective equipment. Further applications, such as professional tree care within a tree, are expressly excluded. The operator is liable for any damage caused by im- proper operation. It is only permitted to use the saw chains and bar combinations stated in the operating instructions for this device. Any other application not in accordance with the designated use described here shall be regarded as misuse. The chain saw must not be used in the commer- cial sector. CAUTION! Danger of injury due to non-designat- ed use! If wood or other substances embedded with foreign bodies are sawn with the chain saw, injury can result.

Only use the chain saw for light wood sawing work.

Before sawing wood, check for for- eign bodies, e.g. nails, screws, fit- tings.

Do not saw off any branches that are directly or at an acute angle above the user or other persons.

Even when using the device as intended, there is always a certain residual risk that cannot be ex- cluded. The following hazards cannot be ruled out due to the nature and design of the device.

Contact with the exposed teeth of the chain (risk of cutting)

Access to the moving chain (risk of cutting)

Sudden and unexpected movement of the bar (risk of cutting)

Separation of parts of the chain (e.g. risk of cutting/injury)

Separation of parts of the wood being worked

Inhalation of particles of the wood being worked on.

Emissions from the petrol engine.

Contact of the fuel (petrol/oil) with the skin.

Impairment of hearing during work if ear de- fenders are not used.

2.4 Safety and protective devices

Check the device daily for damage and to en- sure that it is in a condition for safe operation before every use and after every fall or other incidents, such as external force due to im- pact or bumps.

Check the tightness of the fuel system and the functionality of the safety devices. Do not continue using devices that are not safe for operation. In case of doubt, consult your dealer.

Wear ear defenders during work with the de- vice, especially during a daily working period of more than 2.5 hours. The operation of the device causes intense noise that can cause hearing impairment in the user.

Wear gloves to cushion vibration and take regular breaks as a preventative measure against "white finger disease" (due to vibra- tion-induced circulation problems in the hands). Using the device for a longer period of time may result in vibration-induced circu- lation problems in the hands. An exact period of use cannot be determined. This depends on a variety of factors. Observe your hands and fingers during constant use of the device. Consult a doctor if symptoms appear there, such as loss of feeling, pain, itching, impair- ment of physical strength or changes to the skin colour or the skin.

Never run the motor in closed rooms and switch it off if you feel nauseous, dizzy or weak when using this device. Immediately consult a doctor. The device generates toxic exhaust gases when the motor is running. These gases can be odourless and invisible.

Never operate the device in the vicinity of open flames or heat sources. Petrol and lu- bricating oil vapours are highly flammable.

Wear a dust mask if sawdust, mist or smoke are generated when working with the device. These can be dangerous to health.

3.1 Safety instructions for chain saws

Keep all parts of your body away from the saw chain when the saw is running. Be- fore starting the saw, make sure that noth- ing is touching the saw chain. When work- ing with a chain saw, one moment of inatten- tion can mean your clothing or parts of your body coming into contact with the saw chain.

Always hold the chain saw with your right hand on the rear grip and your left hand on the front grip. Holding the chain saw with your hands the other way around increases the risk of injury and is not allowed.

Wear protective goggles and ear defend- ers. Further protective equipment is rec- ommended for the head, hands, legs and feet. Appropriate protective clothing reduces the risk of injury due to flying chips and inad- vertent contact with the saw chain.

Do not work with the chain saw in a tree. Risk of injury when operating a chain saw in a tree.

Always make sure you are standing firmly and only use the chain saw if you are standing on firm, secure and level ground. Slippery ground or unstable standing surfac- es such as on a ladder can lead to a loss of equilibrium or loss of control over the chain saw.

When cutting a branch that is under ten- sion, expect it to spring back. When the tension in the wood fibres is released, the branch under tension can hit the operator and/or cause a loss of control over the chain saw.

Take particular care when cutting under- growth and young trees. The thin material can get caught in the saw chain and hit you or cause you to lose your balance.2500096_b 39 Safety instructions

Carry the chain saw at the front grip when it is switched off, and have the saw chain pointing away from your body. Always put on the protective cover when transporting or storing the chain saw. Careful handling of the chain saw reduces the probability of in- advertent contact with the running saw chain.

Follow the instructions for lubrication, chain tensioning and changing accesso- ries. An incorrectly tensioned or lubricated chain can either tear or increase the risk of kickback.

Keep the grips dry, clean and free from oil and grease. Greasy, oily grips are slippery and result in loss of control.

Only saw wood. Do not use the chain saw for work for which it is not intended. Ex- ample: Do not use the chain saw for saw- ing plastic, masonry or construction ma- terials that are not made of wood. Using the chain saw for non-designated work can lead to dangerous situations.

3.2 Causes and operator prevention of

kickback Kickback can occur if the tip of the chain bar touches an object or if the wood bends and traps the saw chain during cutting. In many cases, contact with the tip of the bar can lead to an unexpected, rearward reaction causing the chain bar to be knocked upwards and to- wards the operator. If the saw chain is trapped on the top edge of the chain bar, the bar can be forced violently back to- wards the operator. Each of these reactions can result in you losing control of the saw, with the possibility of severe injury. Do not rely entirely on the safety devices installed on the chain saw. As user of a chain saw, you should take various measures to be able to work without accident and injury. Kickback is the consequence of incorrect or faulty use of the tool. It can also be prevented by taking suitable precautions as described below:

Hold the saw firmly with both hands, with your thumb and fingers around the grips of the chain saw. Hold your body and arms in a position that allows you to with- stand the kickback forces. If suitable mea- sures are taken, the operator will be able to control the kickback forces. Never release the chain saw.

Avoid any abnormal posture, and do not saw anything above shoulder height. This will avoid inadvertent contact with the tip of the bar, and allow better control of the chain saw in unexpected situations.

Always use replacement bars and saw chains prescribed by the manufacturer. In- correct replacement bars and saw chains can lead to the chain breaking and/or to kickback.

Comply with the instructions of the manu- facturer for sharpening and maintaining the saw chain. Depth limiters set too low in- crease the tendency to kickback.

3.3 Safety information when working

Heed the country-specific safety regulations, e.g. from the relevant trade associations, so- cial security systems, authorities for industrial safety.

Only work in sufficient daylight or artificial lighting.

Keep the working area free from objects (e.g. off-cuts) – danger of stumbling.

The user is responsible for accidents involv- ing other people and their property.

Young people under 16 years of age and people who do not know the operating in- structions are not allowed to use the tool.

If you are working with a chain saw for the first time: Have the salesperson or another expert explain the operation of the chain saw, or attend a course.

To operate the chain saw, you must be rest- ed and in good physical and mental health. If you must not exert yourself for health rea- sons, ask your doctor whether it is possible to work with a chain saw.

Take measures to protect yourself against vibration loads. The actual vibration values may differ from the values specified in the technical data, depending on what the tool is used for. In doing so, take account of the en- tire working process, i.e. also times during which the tool is operating without load, or is switched off. Suitable measures include regu- lar maintenance and care of the tool and the tool attachments, keeping your hands warm, taking regular breaks and planning the work- ing sequences effectively.GB 40 6436 | 6442 Safety instructions

Determine the maximum handling period and set breaks in the work according to the vibration value.

3.3.2 Operating times

Heed the country-specific regulations for the op- erating times of chain saws. The operating times of chain saws can be limited by national and local regulations.

3.3.3 Working with the chain saw

WARNING! Danger of serious injury. If an incompletely mounted chain saw is used, serious injury can be caused.

Only use the chain saw when it has been fully mounted.

Before each use, perform a visual inspection in order to check that the chain saw is complete and does not contain damaged or worn compo- nents. Safety and protective devices must be intact.

Always keep a first-aid kit to hand in case of accidents.

Avoid touching metal objects in the ground or which are conductively connected to the ground.

The personal protective equipment compris- es:

Hearing protection (e.g. ear defenders, especially when working for than 2.5 hours a day)

Protective glasses or face visor incorpo- rated in the protective helmet

Protective trousers with cut protection in- lay

Sturdy working gloves

Safety boots with high-grip soles, steel toe caps, and cut protection inlays

Do not use the chain saw above shoulder height, since safe handling is no longer pos- sible in this way.

When changing position, switch off the en- gine and put on the chain guard.

Switch off the petrol engine when not in use and put the chain guard in place.

Switch the chain saw off before putting it down.

Do not use the chain saw for levering or mov- ing wood.

Only specialist personnel are allowed to saw trunks that are thicker than the length of the chain bar.

Only start the cut once the saw chain is run- ning, never switch on the chain saw already in the kerf.

Make sure that no saw chain oil gets onto the ground.

Do not undertake sawing work in the rain, snow or stormy weather.

Never disable safety and protective devices.

3.3.4 Vibration load

WARNING! Danger due to vibration The actual magnitude of the vibration emissions during the use of the appli- ance may deviate from that stated by the manufacturer. Observe the following in- fluencing factors before or during use:

Is the appliance being used as in- tended?

Is the material being cut or pro- cessed in the proper manner?

Is the cutting tool properly sharp- ened or is the correct cutting tool in- stalled?

Are the handle grips and any option- al vibration grips mounted, and are they firmly attached to the appli- ance?

Only operate the tool at the combustion en- gine speed required for the respective work. Avoid using the maximum speed in order to reduce noise and vibrations.

The noise and vibrations of the tool may in- crease due to improper use and mainte- nance. This leads to health damage. In this case, immediately switch off the tool and have it repaired by an authorised service workshop.

The degree of stress due to vibration de- pends on the work to be performed or on the use of the tool. Estimate the stress and plan appropriate work breaks. This considerably2500096_b 41 Safety instructions reduces stress due to vibration over the en- tire working time.

Extensive use of the tool exposes the opera- tor to vibrations, which can lead to circulatory issues ("white fingers"). To avoid this risk, wear gloves and keep your hands warm. If any symptoms of "white fingers" occur, im- mediately consult a physician. These symp- toms include: Numbness, loss of feeling, tin- gling, itching, pain, reduced muscular strength, changes in the colour or condition of the skin. Normally these conditions affect the fingers, hands or pulse. The risk increas- es at low temperatures (below approx 10°C).

Take long breaks during your working day so you can recover from the noise and the vibra- tions. Plan your work in such a way that the use of appliances that generate strong vibra- tions is spread over several days.

If you notice an unpleasant sensation or disc- olouration of the skin on your hands when us- ing the tool, stop work immediately. Take suf- ficient work breaks. Without sufficient breaks, a hand/arm vibration syndrome can occur.

Minimise your risk of being exposed to vibra- tions. Maintain the tool according to the in- structions in the operating instructions.

If the tool is used frequently, contact your dealer to purchase anti-vibration accessories (e.g. handles).

Define how the vibration load can be limited in a work plan.

3.3.5 Noise pollution

A certain level of noise exposure from this appli- ance is inevitable. Carry out noisy work at ap- proved and specified time periods. Observe rest periods as necessary and restrict the duration of the work to a minimum. For your personal protec- tion and protection of persons in the vicinity, ap- propriate hearing protection must be worn.

3.3.6 Handling of petrol and oil

DANGER! Risk of explosion and fire An escaping petrol/air mixture can cause an explosive atmosphere. Deflagration, explosion and fire can lead to serious and even fatal injuries if fuel is not han- dled properly.

Do not smoke when dealing with petrol.

Only handle petrol out of doors and never in enclosed spaces.

It is essential to heed the code of conduct stated below.

Only transport and store petrol and oil in con- tainers approved for that purpose. Ensure that children have no access to stored petrol and oil.

In order to avoid ground contamination (envi- ronmental protection) when filling, ensure that no petrol or oil enters the soil. Use a fun- nel for filling.

Never fill the appliance in enclosed spaces. Petrol vapours may gather at ground level, and thereby result in a deflagration or even an explosion.

Immediately wipe any spilled petrol off the appliance and the ground. Allow textiles used to wipe off petrol to dry in a well ventilated place before disposing of them. Otherwise, sudden self-ignition may occur.

If petrol has been spilled, petrol vapours oc- cur. For this reason, do not start the appli- ance at the same location but at least 3m away.

Avoid skin contact with mineral oil products. Do not inhale petrol vapours. When filling, al- ways wear protective gloves. Change and clean protective clothing regularly.

Ensure that your clothing does not come into contact with petrol. If petrol has got onto your clothing, change it immediately.

Never fill the appliance while the engine is running or hot.

Safety of persons, animals and property

Always wear sturdy working gloves when assembling the bar and chain.

When installing the bar and chain, take the greatest of care so as not to impair the safety and efficiency of the machine; contact your dealer if you are in doubt. NOTE The machine is supplied with the bar and chain dismantled, and with the mix- ture and oil tanks empty. Make sure that the chain brake is not activated before assembly. The chain brake is released when you pull the hand guard (01/3) in the direc- tion of the handle (01/4).

4.1 Assembly of the guide rail and the saw

1. Loosen and remove the two hex nuts (02/1)

is only used for transporting the packaged machine and is not required any longer.

3. Put (03/a) the groove of the guide rail (03/1)

into the studs (03/2). Push the guide rail in the direction of the machine housing (03/b).

4. Place the sawing chain (04/1) around the

sprocket (04/2) and into the groove of the guide rail (04/3), while ensuring the correct running direction. Place the sawing chain over the reversing sprocket of the guide rail (05/a).

6. Push the guide rail away from the machine

housing until the sawing chain is slightly taut.

7. Only tighten the two hex nuts (06/2) to the

extent that the sawing chain can be made even more taut.

8. Turn the adjustment screw of the chain ten-

sioner(06/3) until the sawing chain is correct- ly tensioned (see chapter 5.4 "Check the chain tension (06, 08)", page44).

IMPORTANT! Danger of damage to the appliance Using petrol alone will damage the en- gine and invalidate the warranty.

Only use high-quality petrol and lubri- cating oil so as to ensure overall per- formance and the service life of the mechanical parts in the long term. NOTE Lead-free petrol tends to leave deposits in the tank if it is stored for more than 2 months. Always use fresh petrol! This machine is equipped with a two-stroke en- gine that runs on a petrol/oil mixture. Suitable oil Use only high-quality synthetic two-stroke engine oils. Oils specially developed for such engines are available from your dealer, which can guaran- tee high performance. Suitable petrol Use only lead-free petrol with a minimum octane rating of 90 RON.

DANGER! Risk of explosion and fire Petrol and mixed fuel are highly inflam- mable!

Exclusively store fuel and mixed fuel in containers specially approved for fuels, and keep them in a safe place away from heat sources and naked flames.

Never leave the containers within reach of children.

Do not smoke when mixing fuel, and attempt to avoid inhaling the petrol vapours. IMPORTANT! Danger of engine damage Pure petrol will result in damage and complete failure of the engine. Guaran- tee claims against the manufacturer are excluded in this case.

Only operate the engine using the specified petrol/oil mixture ratio. NOTE The mixture is exposed to a continuous aging process. Do not prepare exces- sive amounts in order to avoid deposits forming. NOTE Regularly clean the petrol and mixture containers to remove any deposits. An excessively lean mixture increases the risk of a premature piston seizure. The warranty shall be rendered void if the instructions on mixing the fu- el, etc., in this manual are not followed. In the table below you will find the correct mixing ratio, together with an example. Mixing ratio Petrol Oil 50:1 and 1 part (50 Parts Fuel Oil) 5 litres 100 ml

1. Pour about half of the specified quantity of fu-

el into an approved canister.

2. Pour in the full volume of oil specified in the

3. Add the rest of the petrol.

4. Close the container and shake well.

IMPORTANT! Danger of damage to the appliance Due to the metallic abrasion it contains, the use of used oil for lubricating the chain would lead to premature wear of the guide rail and saw chain. Also, the warranty of the manufacturer will be- come void.

Never use used oil, only biologically degradable saw chain oil.GB 44 6436 | 6442 Start-up IMPORTANT! Danger of environmental damage The use of mineral oil for the chain lubri- cation leads to serious environmental damage.

Never use mineral oil, but only bio- logically degradable saw chain oil. Do not use contaminated oil, since this can lead to blockage of the filter in the tank and irreparable damage to the oil pump. Using high-quality oil is a decisive factor in achieving effective lubrication for the cutting ele- ments; used or low-quality oil impairs lubrication and reduces the service life of the sawing chain and guide rail. It is recommended that you fill the oil tank fully every time you refuel (by means of a funnel). The capacity of the oil tank is designed so that the fu- el will run out before the oil does, thereby guaran- teeing that the machine will not be operated with- out lubricant.

5.3 Filling with service products (07)

DANGER! Risk of explosion and fire An escaping petrol/air mixture can cause an explosive atmosphere. Deflagration, explosion and fire can lead to serious and even fatal injuries if fuel is not han- dled properly.

6.2 At the end of a work session

WARNING! Risk of injury by cutting The sharp links of the saw chain can cause serious laceration injuries.

Switch off the motor.

Wear protective gloves. WARNING! Danger of fire The heated machine can ignite waste cuttings (e.g. sawdust, remains of branches or leaves).

Allow the engine to cool down be- fore you place the machine in a room.

To reduce the risk of fire, the ma- chine must be cleaned to remove saw chips, twigs, leaves or surplus grease.

Containers with cutting residues must not be stored inside rooms.

1. Switch off the engine (see chapter 6.1.2

"Switching off the motor (12)", page46).

2. Allow the device to cool down.

3. Remove all traces of saw chips or oil resi-

4. If the saw chain is very dirty, remove the saw

chain and leave it to soak for a few hours in a container of special cleaner. Then rinse it with clean water and spray with an appropri- ate anticorrosion product before mounting it on the device again.

5. Pull the protective cover over the saw chain

before cleaning up the device.

6.3 Changing between normal/summer and

winter operation (29) To prevent the carburettor from icing up at low ambient temperatures (less than 5°C), it is possi- ble to heat the intake air by positioning the slider insert in winter operation. The slider insert can be accessed directly after removing the air filter cov- er, using a screwdriver. IMPORTANT! Danger of engine damage due to overheating! If the chain saw is operated at more than 5 °C and the sliding insert is in the Win- ter position, this can cause it to over- heat.

Before operating, check the ambient temperature and, if necessary, ad- just the position of the sliding insert.

1. Remove the air filter cover (see chapter 8.1

"Removing/remounting the air filter cover (20)", page50).2500096_b 47 Working behaviour and working technique

Below 5°C, i.e. winter operation: The snowflake icon (29/3) must be visible in winter operation.

6. Mount the air filter cover (see chapter 8.1

"Removing/remounting the air filter cover (20)", page50).

7 WORKING BEHAVIOUR AND

WORKING TECHNIQUE DANGER! Danger of fatal injury due to inade- quate technical knowledge! Inadequate technical knowledge can re- sult in extremely serious up to fatal inju- ry!

Only trained and experienced peo- ple are allowed to fell trees and lop branches. DANGER! Danger of fatal injury from uncontrol- lable movements of the machine The moving saw chain develops enor- mous forces that could lead to the sud- den uncontrollable swerving and throw- ing out of the chain saw.

Always hold the chain saw with both hands, the left hand on the front handle and the right hand on the rear handle. Regardless of whether you are left- or right-handed. DANGER! Danger of fatal injury due to kick- back! The operator can be fatally injured by kickback of the appliance.

It is essential to comply with the measures in order to avoid any kick- back. CAUTION! Danger to health from inhaling haz- ardous substances! The inhalation of lubricating oil steam, exhaust gases and sawdust can lead to health impairments.

Always use the prescribed personal protective equipment. CAUTION! There is a risk of injury when the chainsaw is blocked If you try to pull out a cutting apparatus when the cutting apparatus – i.e. the saw chain and guide rail – is blocked while the engine is running, there is a risk of injury and risk of damaging the device.

Switch off the engine and pry open the cut (with a wedge, for example), or make a relief cut using a second chain saw or cutting apparatus. Re- move the jammed cutting apparatus as soon as the cut opens up.

Follow the instructions and proce- dures stated in the following sec- tions to avoid blocking or jamming of the chainsaw. NOTE Courses in the use of chain saws and techniques for felling trees are regularly held by various forestry organisations.

7.1 Using the bumper spike (13)

1. Stick the bumper spike (13/1) into the trunk

and make an arc motion with the chain saw (13/a) so that the chain saw cuts into the wood.

Repeat this work step several times, moving the point of contact of the bumper spike (13/b).GB 48 6436 | 6442 Working behaviour and working technique

7.2 Felling trees (14, 15)

DANGER! Danger of fatal injury from a falling tree! Having no escape route when felling a tree represents a danger of serious and even fatal injury!

Do not start the felling work until you are sure there is an unobstructed escape route away from the tree to be felled. DANGER! Danger of fatal injury from an uncon- trollably falling tree! Uncontrolled falling trees can lead to ex- tremely serious and even fatal injury!

In order to guarantee controlled fell- ing of a tree, leave a bridge between the undercut and the back cut. The length of this bridge should be ap- prox. 1/10 of the trunk diameter.

Do not carry out any felling work in windy conditions. NOTE Only use wedges made from wood, plastic or aluminium. Take the following measures before starting fell- ing work.

Make sure that no other people, animals or objects are in the danger area.

The safe distance from other workplaces or objects should be at least 2½ tree lengths.

Watch out for power lines and other people's property. If necessary, notify the power sup- ply company or the property owner.

Judge the falling direction of the tree. Factors influencing the falling direction of the tree:

Natural lean of the tree

Branches growing on one side

Level ground or slope

Asymmetrical growth, wood damage

Wind direction and wind speed

When working on a slope, always work uphill of the tree to be felled.

Establish your escape route in advance, and make sure that there are no obstacles in the way. The escape route should be at an angle of approx. 45° diagonally behind the falling direction (14).

The trunk must be free from growth, branch- es and foreign bodies (e.g. dirt, stones, loose bark, nails, staples, wire, etc.). Make an undercut a back cut in order to cut down a tree.

1. During back cuts and cross-cuts, place the

bumper spike firmly against the wood to be cut.

2. Saw the first undercut (15/c) horizontally,

then the second undercut at an angle of at least 45° from above. This prevents the chain saw becoming trapped when you make the second undercut. The undercut must be as close as possible to the ground and in the re- quired felling direction (15/E). The depth of the undercut should be about 1/4 of the diam- eter of the trunk.

3. Cut the back cut (15/d) exactly horizontally

opposite to the undercut. The back cut must be made 3-5 cm above the horizontal under- cut.

4. Saw in the back cut (15/c) sufficiently deep

so that a bridge (15/f) of at least 1/10 the trunk diameter remains between the undercut (15/C) and the back cut (15/d). This bridge prevents the tree from twisting and falling in the wrong direction. The tree should start to fall when the back cut (15/d) approaches the bridge (15/f). If the tree falls whilst you are sawing:

Interrupt the back cut if the tree does fall in the wrong direction or leans back and traps the chain saw. To open the cut and fell the tree, drive in wedges in the direc- tion of the required felling line.

Immediately pull the chain saw from the cut, switch it off and put it down.

Walk away in the direction of the escape route.

Watch out for falling branches and twigs.

5. If the tree remains standing, drive wedges in-

to the back cut in order to cause it to fall in a controlled way.

6. At the end of sawing work, immediately re-

move your ear defenders and listen out for signals or warning calls.2500096_b 49 Maintenance and care

Heed the following points during this work:

Brace the chain saw against the tree trunk and sequentially cut off the freely accessible branches on the tree trunk, one after the oth- er (16/a). When working on a slope, carry out preparatory work from below to above.

Leave larger, downward-pointing branches supporting the tree standing at first.

Cut off smaller branches with one cut.

Pay attention to branches under tension, and first saw through them a little from above, then from underneath upwards, in order to prevent the chain saw becoming trapped (16/ b).

First saw free-hanging branches a little from below, then saw entirely through them from above downward (16/c).

Only experienced or trained people should make plunge cuts, longitudinal cuts and bor- ing cuts.

7.4 Cross-cutting (17, 18, 19)

Heed the following points during this work:

When working on a slope, always stand uphill from the tree trunk, because it could roll away.

Guide the chain saw so that there is no part of your body in the extended sweep arc of the saw chain.

Positioning the chain on the trunk:

Position the bumper spike directly adja- cent to the cut edge and allow the chain saw to pivot about this point.

The chain saw can slip sideways or jump easily when it is positioned. This depends on the wood and the condition of the saw chain. For this reason, always hold the chain saw firmly.

At the end of the cut, the chain saw swings due to its own weight because it is no longer supported in the cut. Counteract this in a con- trolled way and do not apply pressure so the saw chain does not touch the ground.

After finishing the cut, wait for the saw chain to come to a halt before you switch off the chain saw.

Always switch off the motor of the chain saw before you go to the next tree. The entire length of the tree trunk is in contact with the ground:

Saw through the tree trunk from above, with- out cutting into the ground (17/a). Tree trunk is lying raised at one end:

To prevent the chain saw becoming trapped and the wood splintering, first saw through 1/3 of the trunk diameter from below (18/a), then saw through the remainder from above, parallel to the cut made from below (18/b). Tree trunk is lying raised at both ends: To prevent the chain saw becoming trapped and the wood splintering, first saw through 1/3 of the trunk diameter from above (19/a), then saw through the remainder from below, parallel to the cut made from above (19/b).

7.5 Cutting converted timber

Heed the following points during this work:

Use a secure cutting surface (sawing trestle, wedges, beams).

Make sure you are standing securely and that your bodyweight is evenly distributed.

Secure logs to prevent them twisting.

Only start the cut once the saw chain is run- ning. Never switch on the chain saw already in the kerf.

Do not secure the wood with your foot and do not get another person to hold it.

8 MAINTENANCE AND CARE

DANGER! Risk of injury or death due to improp- er maintenance Maintenance work carried out by unqual- ified persons and the use of non-ap- proved spare parts can result in serious injuries and even death during operation of the appliance.

Do not remove or deactivate any safety installations.

Use only approved OEM spare parts.

Ensure through regular and proper maintenance that the appliance is in a clean and functional condition at all times.GB 50 6436 | 6442 Maintenance and care DANGER!

der the housing, then place the air filter cover on the device.

2. Press the retaining clips (20/1) onto the air fil-

ter cover (20/b) until they snap into place.

8.2 Cleaning the air filter (21)

IMPORTANT! Hazard due to dirty, damaged or missing air filter The device engine can suffer irreparable damage if the air filter is missing, dirty, or defective.

Cleaning the air filter is a prerequi- site for correct operation and a long service life of the device. To prevent damage to the engine, do not work without a filter or if the filter is dam- aged.

Cleaning should be carried out after every 15 hours of machine use.

Never wash the filter element; it must always be replaced it if it be- comes too dirty or is damaged. Removing the air filter

1. Switch off the engine and let it cool down.

2. Remove the air filter cover (see chapter 8.1

"Removing/remounting the air filter cover (20)", page50).

3. Loosen the wing nuts (21/1).

4. Pull the air filter (21/2) up and away (21/a).

5. Cover the intake opening (21/3) with a clean

cloth. This prevents dirt particles from falling into the carburetor space.

6. Separate both parts of the air filter (21/4).

Cleaning the air filter

1. Clean the nylon filter with a brush or fine bris-

tles; if necessary, blow off particles carefully from the inside to the outside with com- pressed air. Mounting the air filter

1. Put both parts of the air filter (21/4) back to-

2. Place (21/b) the air filter (21/2) on the intake

3. Fasten the air filter tightly with the wing nuts

(21/1).2500096_b 51 Maintenance and care

8.3 Checking/replacing the spark plug (22,

23) In case of damage to the insulation, strong elec- trode erosion or heavily oil-contaminated elec- trodes, the spark plug must be replaced. Preparation

1. Switch off the engine and let it cool down.

2. Remove the air filter cover (see chapter 8.1

"Removing/remounting the air filter cover (20)", page50).

1. Remove the spark plug (22/2) with the sup-

plied combination wrench.

2. Clean the electrode with a brush (23/1).

3. Measure the distance (23/2). The gap dimen-

sion must be 0.6-0.7mm. Changing the spark plug

1. Remove the spark plug (22/2) with the sup-

plied combination wrench.

2. Screw in the new spark plug until it stops.

3. Push the spark plug connector onto the spark

To prevent asymmetrical wear, the guide rail should be turned around regularly. The following maintenance work must be carried out:

Grease the bearing of the reversing sprocket (27).

Clean (25) the groove of the guide rail with a scraper (not included in the scope of supply).

Use a flat file to remove burrs from the guide flanks and compensate for any deviations be- tween the guides. The guide rail must be replaced if:

The depth of the groove is less than the height of the pulling link (which is never al- lowed to touch the base of the groove);

The inner guide wall is worn to such an ex- tent that the chain tilts to the side.

8.5 Sharpening the saw chain (24)

DANGER! Danger of fatal injury due to kick- back! Improperly sharpened saw chain in- creases the danger of kickback and thus the danger of fatal injury.

Sharpen the saw chain properly to reduce the risk of kickback. NOTE Inexperienced chain saw operators are recommended to have the saw chain sharpened by a specialist at the custom- er service. The saw chain must always be well-sharpened for reasons of safety and efficiency. Sharpening is required if:

The saw chips are like sawdust.

Greater force is necessary for cutting.

The cut is not straight.

Fuel consumption increases. If you get trained customer service personnel to sharpen the chain for you, they will be able to do this with the appropriate tools for a minimum of material removal and even sharpening of all teeth. You can sharpen the saw chain yourself using special round files whose diameters are adapted to the specific chain type (see chapter 8.10 "Chain maintenance table", page53). A certain amount of skill and experience is necessary to avoid damage to the teeth. To sharpen the saw chain:

1. Switch off the engine, release the chain

brake, and clamp the guide rail firmly in a suitable vice with the saw chain mounted, while ensuring that the chain can move free- ly.

2. Tension the chain if it is slack.

3. Place the file in the corresponding guide and

then guide the file through the opening of the tooth making sure that you keep an even an- gle according to the tooth profile.

4. Only perform a few strokes of the file and ex-

clusively in the forwards direction, then re- peat the working step on all teeth in the same orientation (right or left).GB 52 6436 | 6442 Maintenance and care

5. Reverse the position of the guide rail in the

vice and repeat the working step on the re- maining teeth.

6. Check that the limit tooth does not project be-

yond the checking tool, and file off any pro- jection using a flat file, then round down the profile.

7. After sharpening, clean away all filings and

dust, then lubricate the saw chain in an oil bath. The chain must be renewed if:

The length of the teeth is less than 5 mm;

Where applicable: The mark on the teeth of the cutting elements is exceeded;

The play on the links at the chain rivets is ex- cessive.

8.6 Checking the chain lubrication (26)

Never operate the device without sufficient chain lubrication. Otherwise you reduce the service life of the device. You should therefore check the amount of oil in the oil tank and the oil supply each time before starting work.

1. Start the device.

2. Hold the running chain saw about 15 cm

above a tree stump or a suitable foundation. A light oil film should form on the tree stump (26/1) if there is sufficient lubrication.

8.7 Adjusting the chain lubrication (28)

DANGER! Danger of fatal injury and danger of extremely severe injury. Danger of fatal injury and danger of ex- tremely severe injury when the engine is switched on.

Carry out all work with the engine switched off. The oil supply rate can be adjusted with an ad- justing screw. The adjusting screw is on the bot- tom of the device (28/1). Use a small screwdriver to adjust the supply rate:

Turn it clockwise to decrease the supply rate

Turn it counterclockwise to increase the sup- ply rate When working, you should regularly check whether there is sufficient oil present in the oil tank.

8.8 Checking a standstill when the saw

chain is running in idle WARNING! Danger from moving saw chain A saw chain moving at idling speed can cause life-threatening injuries when working.

Never work with the chain saw when the saw chain is moving at idling speed.

Before every use, check that the saw chain is at a standstill if the en- gine is running at idling speed.

1. Start the engine and let it run at idling speed.

2. Check that the saw chain is stationary.

3. If the saw chain is moving, the following er-

rors could be present:

Idle speed is too high (see chapter 8.9 "Setting the idling speed on the carburet- tor", page52).

The coupling is defective, contaminated or incorrectly set. Contact an AL-KO ser- vice centre.

8.9 Setting the idling speed on the

carburettor The idling speed is specified in the technical data (see chapter 13 "Technical data", page56). It is best adjusted with the aid of a speed counter. If the idling speed is correctly set, the engine runs round at idling speed and the saw chain does not move. Depending on the operating location (mountain, lowland), the idling setting must be corrected using the "T" idling speed stop screw. NOTE The regulating screws "L", for idle fuel mixture, and "H", full load mixture, may only be adjusted by an AL-KO service station. The saw chain moves without the throttle being applied: The idling speed is too high.

1. Turn the "T" idling stop screw (11/5) anti-

clockwise a little until the saw chain no longer moves. The engine continually dies if the throttle is not applied: The idling speed is too low.2500096_b 53 Maintenance and care

1. Turn the "T" idling stop screw (11/5) clock-

wise a little until the engine runs smoothly. If the optimum carburettor setting cannot be ad- justed by turning the "T" idling speed stop screw, have the carburettor optimally adjusted by an AL- KO service station.
