3 SAFETY INSTRUCTIONS

• Check the device daily for damage and to ensure 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 impact 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 device, 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 vibration-induced circulation problems in the hands). Using the device for a longer period

of time may result in vibration-induced circulation 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, impairment 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 lubricating 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 Chain saw safety warnings

• Keep all parts of the body away from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating chain saws may cause entanglement of your clothing or body with the saw chain.
  ■ Always hold the chain saw with your right hand on the rear handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.
• Hold the power tool by insulated gripping surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
  ■ Wear safety glasses and hearing protection. Further protective equipment for head, hands, legs and feet is recommended. Adequate protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.
• Do not operate a chain saw in a tree. Operation of a chain saw while up in a tree may result in personal injury.
  ■ Always keep proper footing and operate the chain saw only when standing on

fixed, secure and level surface. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the chain saw.

■ When cutting a limb that is under tension be alert for spring back. When the tension in the wood fibres is released the spring loaded limb may strike the operator and/or throw the chain saw out of control.
■ Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.
- Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chain saw always fit the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
■ Follow instructions for lubricating, chain tensioning and changing accessories. Improperly tensioned or lubricated chain may either break or increase the chance for kick-back.
- Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control.
- Cut wood only. Do not use chain saw for purposes not intended. For example: do not use chain saw for cutting plastic, masonry or non-wood building materials Use of the chain saw for operations different than intended could result in a hazardous situation.

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 towards the operator.

If the saw chain is trapped on the top edge of the chain bar, the bar can be forced violently back towards 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 withstand the kickback forces. If suitable measures 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 manufacturer for sharpening and maintaining the saw chain. Depth limiters set too low increase the tendency to kickback.

3.3 Safety information when working

■ Heed the country-specific safety regulations, e.g. from the relevant trade associations, social 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 involving other people and their property.

3.3.1 Operator

■ Young people under 16 years of age and people who do not know the operating instructions 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 reasons, 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 entire working process, i.e. also times during which the tool is operating without load, or is switched off. Suitable measures include regular maintenance and care of the tool and the tool attachments, keeping your hands warm, taking regular breaks and planning the working sequences effectively.

■ 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 operating 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 components. Safety and protective devices must be intact.

■ Never work alone.

■ 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 comprises:

■ Protective helmet
■ Hearing protection (e.g. ear defenders, especially when working for than 2.5 hours a day)
■ Protective glasses or face visor incorporated 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 possible in this way.
  ■ When changing position, switch off the engine 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 moving 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 running, 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

■ Danger due to vibration

The actual vibrations emitted during the use of the appliance may deviate from those stated by the manufacturer. Observe the following influencing factors before or during use:

Is the appliance being used as intended?
Is the material being cut or processed in the proper manner?
Is the appliance in a proper condition of use?
Is the cutting tool properly sharpened or is the correct cutting tool installed?
Are the handle grips and any optional vibration grips mounted, and are they firmly attached to the appliance?

■ Only operate the tool at the combustion engine 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 increase due to improper use and maintenance. 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 depends on the work to be performed or on the

use of the tool. Estimate the stress and plan appropriate work breaks. This considerably reduces stress due to vibration over the entire working time.

• Extensive use of the tool exposes the operator 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, immediately consult a physician. These symptoms include: Numbness, loss of feeling, tingling, 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 increases at low temperatures (below approx 10°C).
  Take long breaks during your working day so you can recover from the noise and the vibrations. Plan your work in such a way that the use of appliances that generate strong vibrations is spread over several days.
  If you notice an unpleasant sensation or discoloration of the skin on your hands when using the tool, stop work immediately. Take sufficient work breaks. Without sufficient breaks, a hand/arm vibration syndrome can occur.
• Minimise your risk of being exposed to vibrations. Maintain the tool according to the instructions 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 appliance is inevitable. Carry out noisy work at approved and specified time periods. Observe rest periods as necessary and restrict the duration of the work to a minimum. For your personal protection and protection of persons in the vicinity, appropriate 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 handled 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 containers approved for that purpose. Ensure that children have no access to stored petrol and oil.
In order to avoid ground contamination (environmental protection) when filling, ensure that no petrol or oil enters the soil. Use a funnel 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 occur. For this reason, do not start the appliance at the same location but at least 3 m away.
- Avoid skin contact with mineral oil products. Do not inhale petrol vapours. When filling, always 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.

3.3.7 Safety of persons, animals and property

5 START-UP

5.1 Fuel

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

■ Only use high-quality petrol and lubricating oil so as to ensure overall performance 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 engine 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 guarantee high performance.

Suitable petrol

Use only lead-free petrol with a minimum octane rating of 90 RON.

5.1.1 Mixing fuel

⚠️ DANGER! Risk of explosion and fire. Petrol and mixed fuel are highly inflammable!

■ 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. Guarantee 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 excessive amounts in order to avoid deposits forming.

i 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 fuel, 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 fuel into an approved canister.
2. Pour in the full volume of oil specified in the table.
3. Add the rest of the petrol.
4. Close the container and shake well.

5.2 Chain lubricant

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 become void.

■ Never use used oil, only biologically degradable saw chain oil.

IMPORTANT! Danger of environmental damage. The use of mineral oil for the chain lubrication leads to serious environmental damage.

■ Never use mineral oil, but only biologically 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 elements; 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 fuel will run out before the oil does, thereby guaranteeing that the machine will not be operated without 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 handled 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.

Filling with fuel

1. Switch off the engine and pull the protective cover over the sawing chain.
2. Clean the tank cap (07/1) and the surrounding area so that no dirt will drop into the tank.
3. Open the tank cap (07/1) carefully because pressure may have built up inside.

2. Push the guide rail away from the machine housing until the saw chain is correctly tensioned.
3. Tighten the hexagonal nuts (06/2).

5.5 Checking the chain brake (09)

WARNING! Danger of fatal injury and danger of extremely severe injury due to a defective chain brake. Extremely serious injury and even fatal injury of the operator can be caused if the chain brake does not function, e.g. due to kickback by the running saw chain.

• Check the chain brake each time before starting work.
• Do not switch the chain saw on if the chain brake is defective. in this case, have the chain saw checked in a customer service workshop.

The unit is provided with a safety brake system (chain brake).

The chain brake was developed to immediately halt movement of the chain in case of kickback. The brake is normally actuated automatically through inertia.

This brake can also be actuated manually for control purposes.

1. Start the engine and firmly hold the device grips with both hands.
2. Operate the safety locking switch (01/8) and throttle lever (01/7) to keep the chain moving, then press the hand guard (09/1) forward using the back of your left hand (09/a); the chain must stop immediately.
3. If the saw chain stops, immediately release the safety locking switch and then the throttle.

- Do not release the handles as long as the motor is running.
■ Do not use the chain saw if you are:

Tired
Unwell
■ Under the influence of alcohol, medicines and drugs

6.1 Switching the engine on and off

WARNING! Risk of explosion and fire. An escaping petrol/air mixture can cause an explosive atmosphere. Deflagation, explosion and fire can lead to serious and even fatal injuries if fuel is not handled properly.

- Do not start the engine unless you are at least 3 metres away from the place where you filled the fuel.

6.1.1 Starting the engine (10, 11)

CAUTION! Risk of injury from cable starter. Due to rapid retraction of the cable starter, the hand is pulled too quickly towards the engine. This can lead to bruises and sprains.

■ Never wind the cable starter around your hand.

IMPORTANT! Danger of damage to the appliance. If the cable starter is pulled out too far, this can cause damage.

- Do not to pull the cable out fully or cause it to rub against the edge of the cable guide opening; also, do not let go of the handle in such a way that the cable is retracted in an uncontrolled manner.

IMPORTANT! Danger of damage to the appliance. If the engine is operated at high speed and the chain brake actuated, the clutch may overheat.

- Avoid letting the engine run at high speed with the chain brake actuated.

Cold start

A cold start means starting the engine after it has been switched off for at least 15 minutes or after re-filling with fuel.

1. Place the device on a flat level surface, firmly grasp the front handle and press the device

onto the floor. If necessary, put the tip of your right foot on the rear handle.

1. Press the hand guard forward to actuate the chain brake.
2. Remove the protective cover of the saw chain.
3. Press the primer ball (10/1) 3-4 times (10/a).
4. Press the decompression button (11/1). The decompression valve opens and the required pulling force on the starter handle is reduced. The decompression button automatically returns to its original position as soon as the engine is started.
5. Turn the choke knob (11/2) anticlockwise until it stops (corresponding to the mark on the chain saw).
6. Using your free hand, pull the starter grip (11/3) upwards (11/a) until resistance is felt.
7. Do not release the starter grip; pull firmly several times until the engine starts for the first time. Then turn the choke knob (11/2) clockwise until it stops (corresponding to the mark on the chain saw).
8. Pull the starter grip (11/3) firmly several times until the engine starts again.
9. As soon as the engine is running, briefly press the safety locking switch (11/4) and throttle lever (11/5). Thus, the throttle valve of the carburettor is released from the locked position.
10. Let the device run at idle for about one minute.
11. To release the chain brake, pull back the hand guard.

Warm start

If the motor is only briefly shut down, the start procedure can be performed only by pressing the primer ball and the decompression button but not turning the choke knob.

6.1.2 Switching off the motor (12)

1. Release the safety locking switch (12/1) and then the throttle lever (12/2).
2. Allow the engine to run at idling speed for a few seconds.
3. Press the rocker switch (12/3) into the "STOP" position (12/a).

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 before you place the machine in a room.
  ■ To reduce the risk of fire, the machine must be cleaned to remove saw chips, twigs, leaves or surplus grease.

• Containers with cutting residues must not be stored inside rooms.

• Switch off the engine (Switching off the motor (12)).

• Allow the device to cool down.
• Remove all traces of saw chips or oil residues.
• 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 appropriate anticorrosion product before mounting it on the device again.
• 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 possible 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 cover, 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 Winter position, this can cause it to overheat.

■ Before operating, check the ambient temperature and, if necessary, adjust the position of the sliding insert.

1. Remove the air filter cover (see chapter 8.1 "Removing/remounting the air filter cover (20)", page 49).

2. Pull the slider insert (29/1) out of the frame (29/a) by hand.

3. Turn the slide insert vertically (29/b) and reinsert (29/c):
   ■ Above 5 °C, i.e. normal/summer operation: Align the window of the slider insert with the sun symbol (29/2).
   Below 5 °C, i.e. winter operation: Align the window of the slider insert with the snowflake symbol (29/3).

4. Mount the air filter cover (see chapter 8.1 "Removing/remounting the air filter cover (20)", page 49).

7 WORKING BEHAVIOUR AND WORKING TECHNIQUE

⚠️ DANGER! Danger of fatal injury due to inadequate technical knowledge! Inadequate technical knowledge can result in extremely serious up to fatal injury!

■ Only trained and experienced people are allowed to fell trees and lop branches.

⚠️ DANGER! Danger of fatal injury from uncontrollable movements of the machine. The moving saw chain develops enormous forces that could lead to the sudden uncontrollable swerving and throwing 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 kickback! The operator can be fatally injured by kickback of the appliance.

It is essential to comply with the measures in order to avoid any kickback.

CAUTION! Danger to health from inhaling hazardous 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. Remove the jammed cutting apparatus as soon as the cut opens up.
■ Follow the instructions and procedures stated in the following sections 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.
2. Repeat this work step several times, moving the point of contact of the bumper spike (13/b).

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 uncontrollably falling tree! Uncontrolled falling trees can lead to extremely serious and even fatal injury!

In order to guarantee controlled felling of a tree, leave a bridge between the undercut and the back cut. The length of this bridge should be approx. 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 felling 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 2 12 tree lengths.

• Watch out for power lines and other people's property. If necessary, notify the power supply 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

Height of the tree

■ Branches growing on one side

Level ground or slope

Asymmetrical growth, wood damage

Wind direction and wind speed

Snow load

■ 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, branches 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 required felling direction (15/E). The depth of the undercut should be about 1/4 of the diameter 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 undercut.
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 direction 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.

• If the tree remains standing, drive wedges into the back cut in order to cause it to fall in a controlled way.

• At the end of sawing work, immediately remove your ear defenders and listen out for signals or warning calls.

7.3 Delimbing (16)

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 other (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 boring 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 adjacent 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 controlled 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, without 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 running. 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.

8.2 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 prerequisite 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 damaged.
  ■ 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 becomes 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)", page 49).
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.

Changing the spark plug

1. Remove the spark plug (22/2) with the supplied combination wrench.
2. Screw in the new spark plug until it stops.
3. Push the spark plug connector onto the spark plug.

8.4 Guide rail (25, 27)

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).
■ Clean the lubrication holes.
■ Use a flat file to remove burrs from the guide flanks and compensate for any deviations between 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 allowed to touch the base of the groove);
■ The inner guide wall is worn to such an extent that the chain tilts to the side.

8.5 Sharpening the saw chain (24)

⚠️ DANGER! Danger of fatal injury due to kickback! Improperly sharpened saw chain increases the danger of kickback and thus the danger of fatal injury.

■ Sharpen the saw chain properly to reduce the risk of kickback.

i NOTE Inexperienced chain saw operators are recommended to have the saw chain sharpened by a specialist at the customer 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.
■ Vibration increases.
■ 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 (Chain maintenance table). 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 freely.
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 angle according to the tooth profile.
4. Only perform a few strokes of the file and exclusively in the forwards direction, then repeat the working step on all teeth in the same orientation (right or left).
5. Reverse the position of the guide rail in the vice and repeat the working step on the remaining teeth.
6. Check that the limit tooth does not project beyond the checking tool, and file off any projection 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 excessive.

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 extremely 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 adjusting screw. The adjusting screw is on the bottom 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 supply 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 engine 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 errors could be present:

- Idle speed is too high (Setting the idling speed on the carburettor).

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

8.9 Setting the idling speed on the carburettor

The idling speed is specified in the technical data (Technical data). 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 (11/6) 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.

1. Turn the "T" idling stop screw (11/6) clockwise a little until the engine runs smoothly.

If the optimum carburettor setting cannot be adjusted by turning the "T" idling speed stop screw, have the carburettor optimally adjusted by an AL-KO service station.

Before transporting, carry out the following measures:

1. Switch off the engine.
2. Allow the device to cool down.
3. Remove all traces of saw chips or oil residues.
4. Pull the protective cover over the guide rail.
   Only carry the chain saw using the handle. When doing this, the guide rail points to the rear.
   In vehicles: Secure the chain saw against tipping over, damage and leakage of service products.

11 STORAGE

Thoroughly clean the appliance after each use and – if present – attach all covers. Store the appliance in a dry, lockable place out of the reach of children.

If the appliance is not going to be used for longer than 2 – 3 months, the following work is necessary to avoid any damage:

1. Completely drain the fuel and oil.
2. Remove the saw chain and guide rail, clean it and spray it with rust-proofing oil.
3. Store the appliance in a cool, dry place.

IMPORTANT! Danger of damage to the appliance. Dried-on/sticky saw chain oil can lead to damage to oil-channelling components after lengthy storage.

■ Remove the saw chain oil from the appliance before an extended period of storage.

12 DISPOSAL

Petrol and motor oil do not belong in household waste or the public sewer system, but should be collected and disposed of separately.

■ Before disposing of the device you must empty the fuel tank and the engine oil tank!
Packaging, equipment and accessories are made from recyclable materials, and must be disposed of accordingly.
