  Wear a safety helmet for all work in the forest. This provides protection from falling branches. Check the safety helmet regularly for damage. This must be replaced after 5 years at the latest. Only use approved safety helmets.
  The face guard or safety goggles protect against shavings and wood splinters. To prevent injuries to the eyes, you must always wear a face guard or safety goggles when working with the device.
  Always wear hearing protection. The noise emitted by the device may cause hearing damage.

Wear robust protective gloves made of tough material, such as leather.

Wear a dust protection mask when sawing dry wood. Sawdust may form.

6.3 Storage and transport

• Switch off the chainsaw before any transport, even over short distances. Engage the chain brake and fit the chain guard.
  Use the chain guard during transport and storage.
• Secure the machine against tipping over during transport (including in vehicles) to prevent fuel loss, damage or injury.
• Carry the device only by the front handle. In doing so, the guide bar points backwards, away from your body (see fig. L).
• Keep the hot silencer away from your body. There is a risk of burns!
  Clean and maintain the chainsaw before storage.
  Store the device in a safe and dry location. Also secure it from unauthorised access.

6.4 Environmental safety

National and/or municipal regulations may impose time restrictions on the use of noise-generating, motorized devices. Ask your local administration about this.
The device must not be operated indoors or in other poorly ventilated areas. There is a danger of suffocation due to the toxic exhaust gases / lubricating oil vapours.

Work must be stopped immediately in event of nausea, headaches or visual disturbances as well as dizziness. These symptoms can be caused, among other things, by excessive exhaust gas concentrations. Dusts such as wood dust, vapour and smoke can also arise during the sawing process. Good ventilation must be ensured and a dust protection mask must be worn.

Only carry out work in daylight.
Also, do not work in adverse weather conditions, such as rain or wind. There is an increased risk of accidents here.
- Keep your work area clean and tidy.

• Keep bystanders (in particular children and animals) at least 15m away from the work area while using the chainsaw. Distractions may cause you to lose control of the device.

Before starting work, make sure that there are no persons, animals or property in the danger zone.
- Do not work near wire fences or in areas with loose old wire.
Have fire extinguishers ready when working in highly flammable environments such as dry grass, etc. There is a risk of fire!

6.5 Refill with fuel

Petrol is very easily flammable. Keep away from naked flames when refuelling and do not smoke while doing so. There is a risk of fire!
■ Be careful not to spill petrol. Ensure that no petrol or chain oil gets into the soil. Use suitable sheeting or similar to help with this.
Refuel only in well-ventilated areas. Petrol vapours can easily ignite or explode.
- Switch off the engine before refuelling and allow the device to cool down. If petrol has been spilled, clean the affected areas immediately. Also, do not let any fuel get on your clothes, otherwise change immediately.

Also avoid skin and eye contact with petrol or lubricants (oil).
- Do not breathe in fuel vapours/lubricating oil vapours.
Watch out for leaks. If petrol is leaking, do not start the engine. There is a danger from burns.
- Carefully open the fuel cap so that any overpressure can slowly escape and no petrol sprays out.

6.6 Before commissioning

WARNING

Always carry out checks before use and with the engine switched off.

Check the device before each use and after it has fallen to the ground to ensure that it is in safe operating condition.

Check that all moving parts are working properly. Many accidents are caused by poorly maintained tools.

Have damaged parts repaired by qualified specialist personnel.

Only use the chainsaw and accessories in accordance with these instructions. Take into account the working conditions and the work to be performed. Using power tools for operations other than those intended can lead to hazardous situations.

Regularly check the chain brake for proper functioning (front hand guard, see Fig. B).
- Check the guide rail to make sure it is mounted correctly.

• Check that the saw chain is properly tensioned. Follow the instructions for lubrication, chain tensioning and replacing accessories. An improperly tensioned or lubricated chain can break or increase the risk of kick-back.

• Keep cutting tools sharp and clean. Sharpen regularly and replace worn parts in good time. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

• Check that the throttle and the throttle interlock move easily. The throttle lever must spring back to the starting position.
• Check that there is enough fuel and chain lubricating oil in the tank.
• Check that the handles are clean, dry and free from oil and dirt.
• Never carry out the work alone. In an emergency, someone must be nearby.
  Only use the chainsaw when standing on firm, safe and level ground. Avoid abnormal postures. Slippery ground or unstable standing surfaces (e.g. on a ladder) can cause loss of balance or loss of control of the chainsaw. Keep proper footing and balance at all times. This will allow you to better control the chainsaw in unexpected situations.
• Do not work with the chainsaw in a tree. There is a risk of injury when operating in a tree.
• Never saw above shoulder height.
  Always hold the chainsaw with your right hand on the rear handle and your left hand on the front handle (see fig. D). Holding the chainsaw using the opposite grip increases the risk of injuries and must be avoided.
• Keep all body parts away from the saw chain when the chainsaw is running. Before starting the chainsaw, ensure that the saw chain is not touching anything. When working with a chainsaw, a moment of carelessness can result in clothing or body parts being caught by the saw chain.

• Switch off the chainsaw immediately if you notice any noticeable changes in the device's behaviour.
  If the chainsaw has come into contact with stones, nails or other hard objects, stop the engine immediately and check the saw chain and guide rail for damage.

• Do not drop the chainsaw, do not hit it against obstacles and never use the guide rail as a lever.

Only saw in wood with the chainsaw

• When cutting a branch that is under tension, expect it to spring back. If the tension in the wood fibres is released, the tensioned branch can hit the operator and/or wrest the chainsaw from control.

• Be especially careful when cutting undergrowth and young trees. The thin material can get caught in the saw chain and hit you or throw you off balance.

6.7 Vibrations

WARNING

Avoid the risks associated with vibration, e.g. the risk of white finger syndrome (circulatory disorders).

Raynaud's syndrome is a vascular disease that causes the small blood vessels on the fingers and toes to cramp in spasms. The symptoms include: Numbness, loss of sensitivity, tingling, itching, pain, decrease in strength, change of colour or condition of the skin. The affected areas are no longer supplied with sufficient blood and therefore appear extremely pale. The frequent use of vibrating tools can cause nerve damage in people whose circulation is impaired (e.g. smokers, diabetics). If you notice unusual adverse effects, stop working immediately and seek medical advice. For long-term and regular users, it is therefore recommended that you keep a close eye on the condition of your hands and fingers. Observe the following information to reduce hazards:

• Keep your body warm, especially your hands, especially in cool weather.
  Take regular breaks and move your hands to promote circulation.

• Limit the use of high-vibration tools per day and spread them out over several days. Make a work plan that limits the vibration load.

• Ensure that the device vibrates as little as possible through regular maintenance and fixed parts on the device. Replace worn components immediately.
  Change your working position regularly.
  If the machine is to be used or operated frequently, you should contact your specialist dealer and request anti-vibration accessories (handles) if applicable.

6.8 Safety functions of the chainsaw (Fig. 1)

The FRONT HAND GUARD (1) protects the left hand of the operating person should it slip off the front handle while the chainsaw is running.
The REAR HAND GUARD (12) protects the right hand from contact with a discarded or broken saw chain.

The CHAIN BRAKE is a safety function for minimising injuries from kick-backs by stopping a running saw chain in milliseconds. It is activated by the front hand guard in the event of a kick-back.

The THROTTLE INTERLOCK (9) prevents the engine from randomly accelerating. The throttle lever can only be pressed when the throttle interlock is pressed.
- The CLAW STOP (15) supports the chainsaw on the wood while working. Never work without a claw stop, the chainsaw can pull the operator forward. Use the claw stop for cutting tree trunks or thick branches. Using the claw stop increases work safety, reduces personal strain when working and vibrations are also reduced. The claw stop must always be positioned on the tree trunk when using the chainsaw. Push the claw stop onto the tree trunk using the rear handle. To cut, push the front handle in the direction of the cutting line. The claw stop may need to be repositioned for further cutting.

6.9 Precautionary measures against kick-back

WARNING

Watch out for kick-back when working with the device. There is a danger of injury. Avoid kick-backs through caution and correct sawing technique.

• Touching with the rail tip can sometimes lead to an unexpected backward reaction, whereby the guide bar whips up and in the direction of the operator (Fig. 1).
• Kick-back can arise if the tip of the guide rail touches an object or if the wood bends and the saw chain jams in the cut.
  Before the saw chain is guided into the cutting area, it can slip away to the side or jump up. (Attention! Increased risk of kickback!)
  If the saw chain jams on the top edge of the guide bar, the chainsaw can jerk back suddenly in the direction of the operator (fig. 1).
  If the saw chain jams on the lower edge of the guide bar, the chainsaw can jerk forward suddenly away from the operator (fig. J).
• Be extremely careful when using the chain of the chainsaw to continue cutting into a cut that has already been started.
• Do not saw branches or pieces of wood that could change their position during the sawing process or where the cut closes during the sawing process.
  Each of these reactions can lead to you losing control of the saw and possibly suffering a serious injury. Never rely solely on the safety equipment integrated in the chainsaw. As a chainsaw user, take various measures to work without accidents and injuries.

Kickback is the result misuse and/or incorrect operating procedures or conditions. It can be prevented by suitable precautionary measures, as described in the following:

Hold the saw firmly with both hands, with the thumbs and fingers enclosing the chainsaw handles. Bring your body and arms into a position in which you can absorb the kick-back forces. If suitable measures are implemented, the operator will be able to withstand the kick-back forces. Never let go of the chainsaw (see fig. D).
- Avoid an unusual body stance and never saw above shoulder height. This will help to avoid unintentional contact with the rail tip, and enable improved control of the chainsaw in unexpected situations.
Always use replacement guide rails and saw chains prescribed by the manufacturer. Incorrect replacement guide rails and saw chains may cause the saw chain to break and/or lead to kick-back.
Adhere to the instructions of the manufacturer when sharpening and maintaining the saw chain. If the depth limiter is too low, this increases the tendency towards kick-back.
- Do not saw with the tip of the guide rail. There is a risk of kick-back.
Make sure that there are no nails or metal pieces in the cutting area. Pay special attention to nails or pieces of iron around the cutting area. Also be careful when sawing hardwoods where the chain can get caught. This can cause kick-back.
- Start cutting at full power and always keep the chainsaw at maximum speed while sawing.
- Make sure that there are no objects on the floor that you can trip over.

Always pull the start pull cord (4) out straight. Hold the handle of the start pull cord (4) firmly when the pull cord (4) winds back in. Never let the start pull cord (4) whip back in.

9.1.1 Starting the motor when cold

WARNING

Engage the chain brake before every start-up (push the hand guard (1) forward).

ATTENTION

Never allow the start pull cord (4) to spin back. This can result in damage.

• Remove the cover (27) from the guide rail (16).
• Set the chainsaw down on a firm and level surface. The saw chain (17) must not come into contact with the floor.
• Push the front hand guard (1) forwards until it latches into place. The saw chain (17) is clamped by the chain brake.
• Press the fuel pump "primer" (7) 6x.
• Switch the ON/OFF switch (6) to "ON".
  Pull out the cold start (choke) lever (8)
• Place the tip of your shoe in the rear hand guard (12) (see fig. C).
• Hold the chainsaw firmly by the front handle (2) and pull the start pull cord (4) out slowly until you feel the first resistance.
• Now pull the start pull cord (4) and the engine should start. If the engine does not start, repeat the process. So long as the cold start (choke) (8) lever is pulled out (the engine will run for only a short time and then stop.
• As soon as the engine has stopped, actuate the throttle interlock (9) and the throttle (10) together. The cold start (choke) lever (8) will automatically spring back to the "warm start" operating position.
• Now pull the start pull cord (4) again and the engine should start.

If the engine does not start even after several attempts, read the "Troubleshooting" chapter.

NOTE

With high outside temperatures, it may be necessary to start the engine without the choke even when the engine is cold!

• Release the chain brake by pulling the front hand guard (1) backwards (see fig. D). CAUTION! The chain brake is now released. If the throttle (10) is actuated together with the throttle interlock (9), the saw chain (17) starts up.

9.1.2 Starting the motor when warm

(The device stood still for less than 15-20 minutes)

WARNING

Engage the chain brake before every start-up (push the hand guard (1) forward).

• Push the front hand guard (1) forwards until it latches into place. The saw chain (17) is clamped by the chain brake.
• Switch the ON/OFF switch (6) to "ON".
• The cold start lever (choke) (8) does not have to be pulled to start a warm engine.
• Place the tip of your shoe in the rear hand guard (12) (see fig. C).
• Hold the chainsaw firmly by the front handle (2) and pull the start pull cord (4) out slowly until you feel the first resistance.
• Now pull the start pull cord (4) quickly. The device should start after 1-2 pulls. If the device has still not started after 6 pulls, repeat the process described under "Starting the engine when cold".

9.2 Shutting the engine off

9.2.1 Emergency stop procedure

If it is necessary to stop the device immediately, set the ON/OFF switch (6) to "OFF".

9.2.2 Normal procedure

• Release the throttle (10). The engine goes into idle speed.
• Then set the ON/OFF switch (6) to "OFF".

9.3 Operating while idle

ATTENTION

When idling, the saw chain (17) must be stationary. If the saw chain (17) moves, adjust the idle speed!

NOTE

If the saw chain (17) moves at idle or the engine stops on its own when the throttle is released, a carburettor adjustment must be made (see chapter "Maintenance of the carburettor settings").

• Pick up the chainsaw.
• Use the left hand to hold the front handle (2) firmly.
• Use the right hand to hold the rear handle (11) firmly. The heel of the hand rests on the throttle interlock (9) and the index finger operates the throttle lever (10) (see fig. D).
  After actuating the throttle lever (10) once, the engine runs at idle speed.
• Allow the engine to warm up briefly.

9.4 Checking and adjusting chain lubrication

ATTENTION

• Never work without chain lubrication! If the saw chain runs dry, the set of blade and saw chain will be irreparably destroyed in a short time.
  Always check chain lubrication before working.

Note

Only use saw chain oil, preferably biodegradable. Do not use waste oil, engine oil, etc.

Check during work that the chain lubrication is working.

Hold the chainsaw during operation, at medium speed, over a sawed-off tree stump or a suitable surface. If the lubrication is sufficient, a light film of oil will form on the tree stump or surface (see fig. E).

• If necessary, the chain lubrication can be increased or decreased by means of the oil adjustment screw (19).

• Use the slotted screwdriver (31) supplied to help:

• First press and then turn the oil adjustment screw (19) clockwise to reduce chain lubrication.

• First press and then turn the oil adjustment screw (19) anti-clockwise to increase chain lubrication.

9.5 Checking the chain brake

WARNING

The chain brake must be checked before each use. The chain brake brakes the saw chain immediately in the event of kick-back.

• Make sure that the front hand guard (1) is free of dirt and moves easily.
• Start the chainsaw as described under 9.1 and accelerate the saw chain to full speed (full throttle).
• With the saw chain running, operate the front hand guard (1). The chain brake must brake and lock the saw chain at max. speed.

WARNING

Increased engine speed for too long with the chain brake locked will damage the engine and the chain drive.

If the saw chain (17) still moves, contact the customer service.

10. Basic working instructions for felling work

WARNING

Danger of injury!

Sawing and felling work as well as all related work may only be carried out by specially trained and briefed persons.

Note

Observe the country-specific regulations for felling work and obtain information from the relevant authority.

• Make sure that no one can be harmed by the falling branches and trees.
• Only the persons required for the felling work may be in the work area.
• Keep the work area at the trunk clear and tidy so that operators have a safe standing area.
• Keep escape routes clear and tidy in order to be able to leave the work area quickly.
• Do not carry out felling work in stronger wind conditions, bad weather or poor visibility.
• Keep distances to the nearest workplace of at least 2 1/2 tree lengths.

10.1 Use and handling

• Never start the device before the guide rail (16), saw chain (17) and chain cover (22) are correctly fitted.
• Do not cut wood that is lying on the ground or try to cut roots that are sticking out of the ground. In any case, make sure the saw chain (17) does not come into contact with the soil, otherwise the saw chain (17) will dull immediately.
• If you accidentally touch a solid object with the device, switch off the engine immediately and inspect the device for any damage.
• Maintain the device carefully. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the device's operation. Have damaged parts repaired before using the device. Many accidents are caused by poorly maintained devices.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• If a blockage occurs between the material to be cut and the saw chain, then switch it off immediately. Wait until the saw chain has come to a standstill. Remove the spark plug connector and put on cut-resistant gloves to remove the blockage. If the guide rail (blade) has to be removed, follow the instructions as described in the chapter "Installation". After removing the blockage and re-installation, a test run must be carried out. If vibrations or mechanical noises are detected during this process, stop work and contact an authorised service centre. Should this hazard occur more often, we recommend training.
• Have the device serviced by qualified personnel. Only use manufacturer's recommended original spare parts.

10.2 Creating the notch cut

Note

The fall notch determines the felling direction of the tree to be felled.

Place the fall notch at right angles to the felling direction.

Saw as close to the ground as possible.

Support the chainsaw with the claw stop (15).

10.2.1 Creating the notch cut (Fig. F)

• First start with the cut of the fall notch A. The depth of the fall notch should be approx. 1/4 of the tree diameter and have an angle of 45^ - 60^ .

10.2.2 Checking the felling direction (Fig. G)

Place the chainsaw with the guide rail (16) at the bottom of the notch cut.

If necessary, recut the notch cut accordingly.

10.3 Carrying out the felling cut (Fig. F)

• Place the felling cut B approx. 2-3 cm higher than the horizontal cut of the fall notch A. Make sure that felling cut B is carried out exactly horizontally.
• Leave approx. 1/10 of the tree diameter, the breaking strip C before felling cut B. Breaking strip C guides the tree to the ground like a hinge and secures it against premature falling.

WARNING

Danger of accident!

Do not under any circumstances saw the breaking strip C during felling cut B, otherwise the tree may fall in an unpredictable direction!

Be prepared for the tree to "slide" uncontrollably when falling on the cut.

Be prepared for the tree to "jump" uncontrollably in one direction when it hits the ground.

• To prevent the chainsaw from jamming in felling cut B, drive aluminium or plastic wedges into felling cut B in good time. Do not use iron wedges.

ATTENTION

Property damage!

Make sure that the wedge does not come into contact with the saw chain (17). It can be severely damaged by this.

10.4 Delimbing work

• Always be aware of the danger of branches snapping back.
• Do not stand on the trunk when delimbing.
• Beware of the kick-back of the chainsaw and avoid making contact with the rail tip of the guide rail.

• Never saw several branches at once.

• Support the chainsaw with the claw stop (15) when delimbing, if possible.

• Make sure that at the end of the cut the chainsaw can swing through under its own weight. It is no longer supported in the cut so hold it securely.
  Take a firm, stable and secure stance when delimiting.

10.4.1 Delimbing work in sections

Shorten long or thick branches before making the final cut (see Fig. N). Otherwise the saw chain (17) can easily jam.

11. Working on tensioned wood

It is essential to follow the correct sequence when working on wood that is tensioned. Otherwise the saw chain (17) may jam or kick-back may occur.

Tensioned wood must always be cut on the compressed side first. Only then perform the separating cut using the opposite side.

This prevents the saw chain (17) from jamming.

ATTENTION

Property damage!

Lying wood must not touch the floor on the underside of the cutting point, otherwise the saw chain (17) may be damaged.

Safe work

• Keep the device in good working order to prevent injuries.
• After dropping the device, check for significant damage or defects.
• Do not use the device whilst standing on a ladder or in an unsafe position.
• Do not be tempted to make a rash cut. This could endanger yourself and others.
• Change your working position regularly. Prolonged use of the device can lead to vibration-induced circulatory disorders of the hands. However, you can extend the duration of use by wearing suitable gloves or taking regular breaks. Be aware that personal predisposition to poor circulation, low outside temperatures or large gripping forces when working reduce the duration of use.

11.1 Wooden branch is bent downwards

• First saw relief cut 1 (approx. 1/3 of the branch diameter) on the compressed side (see fig. K).
• Then make cut 2 (approx. 2/3 of the branch diameter) on the tensioned side (see fig. K).

11.2 Wooden branch is bent upwards

• First saw relief cut 1 (approx. 1/3 of the branch diameter) on the compressed side (see fig. K).

• Then make cut 2 (approx. 2/3 of the branch diameter) on the tensioned side (see fig. K).

12. Transport

• Always use the guide rail cover (27) when transporting.
• Switch off the chainsaw before any transport, even over short distances. Secure the machine against tipping over during transport (including in vehicles) to prevent fuel loss, damage or injury.
• Carry the device only by the front handle (2). In doing so, the guide bar points backwards, away from your body (see fig. L).
• Keep the hot silencer away from your body. There is a risk of burns!

13. Cleaning and maintenance

All instructions regarding maintenance and cleaning must be carried out regularly or daily and before each commissioning. Incorrect maintenance can lead to severe property or personal damages. If this work cannot be carried out by the user themselves, see a specialist dealer.

WARNING

Danger of injury!

Always switch off the device and disconnect the spark plug connector (34) before cleaning.

(see chapter 13.4 Spark plug maintenance).

Note

The device should be thoroughly cleaned after each use.

Only carry out cleaning and maintenance work to the extent specified in this operating manual. Further work must be carried out by qualified specialists.

Maintenance work must be carried out regularly (see chapter "Maintenance intervals").

13.1 Cleaning the engine unit

WARNING

Danger of burning!

Do not touch hot silencers, cylinders or cooling fins.

• Keep protective devices, air vents and the engine housing as free of dust and dirt as possible. Blow it out with low-pressure compressed air.
• Clean the device at regular intervals using a damp cloth and a little detergent. Make sure that no water can penetrate the device interior.

13.2 Cleaning the air filter (Fig. M, N)

Fouled air filters diminish the engine output due to reduced air supply to the carburettor.

Regular inspection is therefore essential. The air filter (33) should be checked regularly and cleaned as required.

The air filter (33) must be checked more frequently in the case of very dusty air.

• Loosen the catch for the air filter cover (5) by turning it anti-clockwise.
• Remove the air filter cover (3).
• Remove the air filter (33).
• Clean the air filter (33) by knocking out or blowing out (with compressed air).

The re-assembly takes place in reverse order.

ATTENTION

Never clean the air filter (33) with petrol or flammable solvents.

13.3 Cleaning the chain drive

WARNING

Danger of injury!

Always wear protective gloves when touching the saw chain (17). Danger of injury due to the sharp cutting teeth!

Note

Clean the chain drive after each use.

• Set the chainsaw down on a level and stable surface.
• Pull the front hand guard (1) back as far as it will go to release the chain brake (see fig. D).
• Turn the chain tensioning screw (21) anti-clockwise using the slotted screwdriver (31) to reduce the tension.
• Remove the two fixing nuts (20) with the spark plug wrench (31).
• Remove the chain cover (22).
• Carefully remove the saw chain (17) from the guide rail (16) and the chain wheel (26).
• Remove the guide rail (16). Clean them with a brush.
• Now thoroughly clean the entire chain drive area and the chain cover (22) with a brush or by blowing it out (with compressed air).

The re-assembly takes place in reverse order.

13.4 Maintenance of the spark plug (Fig. M, N, O)

• Remove the air filter (33) as described in 13.2 "Cleaning the air filter".
• Remove the spark plug connector (34) by turning it to the left and right and pulling it at the same time. Hold and pull the spark plug connector (34) by the connector only. Never pull on the cable!
• Loosen the spark plug with the enclosed spark plug wrench (31).
• The re-assembly takes place in reverse order.

Electrode gap = 0.6mm (distance between the electrodes, between which the ignition spark is generated). Check the spark plug for dirt for the first time after 10 operating hours and clean it with a copper wire brush if necessary.

Then service the spark plug every 50 operating hours.

13.5 Maintaining the chain lubrication

• See chapter "Checking and adjusting chain lubrication".

13.6 Maintaining the carburettor settings

• If the saw chain (17) moves at idle or the engine stops by itself when the throttle is released, a carburettor adjustment must be made.

Note

Have carburettor adjustments (e.g. idle speed) carried out only by qualified specialists to avoid engine damage.

13.7 Maintaining the guide rail

• Remove any burrs on the edge of the guide bar using a metal file.
• Clean the groove of the guide rail (16) using a brush or compressed air. Replace the guide rail (16) as soon as the groove is worn.
• Turn the guide rail (16) after each use to ensure even wear.
• Check the sprocket at the tip of the guide rail (16) for smooth running. If necessary, lubricate it with a bearing oil.

13.8 Sharpening and maintaining the saw chain

WARNING

Danger of injury!

The teeth of the saw chain are very sharp. In order to avoid injuries, always wear thick gloves when in use!

Keep the saw chain in a good operating condition; effective work with the chainsaw is only possible if the saw chain is sharp, well lubricated and properly tensioned. This also reduces the risk of kick-back.

The properly sharpened saw chain (17)

A properly sharpened saw chain (17) goes effortlessly through the wood and requires very little pressure. Do not work with a dull or damaged saw chain (17). It increases physical exertion, magnifies the vibrations and leads to unsatisfactory results as well as greater wear and tear.

• Clean the saw chain (17) regularly.
• Check the saw chain (17) for breaks in the links and damaged rivets.

• Sharpening a saw chain (17) should only be carried out by experienced users!

• Note the angles and dimensions specified below. If the saw chain (17) is not properly sharpened or the depth gauge is too small, there is a higher risk of kick-back effects and the resulting injuries! The saw chain (17) cannot be fixed on the guide bar (16). It is therefore best to remove the saw chain (17) from the guide bar (16) and then sharpen it.

• Select a sharpening tool that is suitable for the chain pitch.

The chain pitch (e.g. 3/8 ) is marked in the depth gauge of each blade.

Only use files specifically for saw chains!

Other files have the wrong shape and the wrong edge. Select the diameter of the file according to your chain pitch. Be sure to also note the following angles when sharpening the cutting links.

A = file angle

B = angle of the side plate

Furthermore, the angle must be maintained for all cutting links.

If the angles are uneven, the saw chain (17) will run erratically, wear out quickly and break prematurely.

Since these requirements can only be met with sufficient and regular practice:

• Use a file holder.

• A file holder must be used when sharpening the saw chain (17) by hand. The correct filing angles are marked on it.

• Hold the file horizontally (at the correct angle to the guide bar (16) and file according to the angle marking on the file holder. Support the file holder on the top plate and the depth limiter.

• Always file the cutting link from the inside out.
• The file only sharpens as it moves forward. Lift the file off as you move backwards.
• Do not touch the drive links or fastening links with the file.
• Turn the file regularly to avoid wear on one side.
• Use a piece of hard wood to remove the burr from cutting edges.

All cutting links must have the same length, otherwise they will also be of different heights.

This causes the saw chain (17) to run erratically and increases the danger of breaking.

13.9 Maintenance intervals

The information given here refers to normal operating conditions. In difficult conditions, such as heavy dust generation and longer daily working hours, the specified intervals should be shortened accordingly.
