The stated vibration emission value was measured in accordance with a standard testing procedure and may be used to compare one power tool to another. The stated vibration emission value may also be used for a preliminary exposure assessment.

The vibration emission value may dier during actual use of the power tool from the stated value depending on the manner in which the power tool is used. Safety precautions aimed at protecting the user should be based on estimated exposure under actual usage conditions (all parts of the operating cycle are to be considered, including, for example, times during which the power tool is turned o and times when the tool is turned on but is running idle). Technical and optical changes can be carried out in the course of further devel- opment without notice. All dimensions, references and information of this instruc- tion manual are therefore without guaran- tee. Legal claims, which are made on the basis of the instruction manual, cannot thus be considered as valid. This device is designed for oper- ation on a power supply network with a system impedance Zmax at the transfer point (domestic connection) of a maximum of

0.335 Ohms. The user must en-

sure that the device is operated only on a power supply network that fulfils this requirement. If necessary, the local power sup- ply company can be asked for the system impedance. Safety information This section describes the basic safety rules when working with the device. Before working with the electri- cal chainsaw, familiarise your- self with all the controls. Prac- tise handling the saw (by cutting logs to size on a sawhorse) and have the functionality, mode of action, sawing techniques and personal safety equipment explained to you by an experi- enced user or an expert. Symbols on the device Observe! Danger! Read and take note of the operat- ing manual belonging to the ma- chine! Wear personal protective equipment. Basically, wear protective goggles or, even better, face protection, safety helmet, cut-pro- tection working clothes, cut-protection gloves, cut- protection safety boots with anti-slip soles and ear protection. Caution! Spring-back - Be care- ful of spring-back of the machine during work.31

Always use the chainsaw with both hands. Do not expose the unit to rain. The device must not be wet, nor should it be operated in a moist environment. Caution! Remove the plug im- mediately from the plug socket in case of damage or cutting through of the mains cable

General safety instructions for power tools WARNING! Read all safety direc- tions and instructions. Omis- sions in the compliance with safe- ty directions and instructions can cause electrical shock, fire and/or severe injuries. Retain all safety directions and in- structions for future use. The term “Power Tools” used in the safety instructions refers to mains-operated power tools (with power cord) and to bat- tery- operated power tools (without power cord).

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents. b) Do not operate power tools in ex- plosive atmospheres, such as in the presence of flammable Iiquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

Keep children and bystanders away while operating a power tool. Dis

tractions can cause you to lose control.

way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. b) Avoid body contact with earthed or grounded surfaces, such as pipes, ra- diators, ranges and refrigerators. The- re is an increased risk of electric shock if your body is earthed or grounded. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d) Do not abuse the cord. Never use the cord for carrying, pulling or un- plugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entan opergled cords increase the risk of electric shock. e) When operating a power tool out- doors, use an extension cord sui- table for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. f) If operating a power tool in a damp location is unavoidable, use a resi- dual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock. Use a surge protector with a release current of 30 mA or less.

a) Stay alert, watch what you are do- ing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alco- hol or medication. A moment of inat- tention white operating power tools may result in serious personal injury. b) Use personal protective equipment. Always wear eye protection. Protec- tive equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropria te conditions will reduce personal injuries. c) Prevent unintentional starting. Ensure the switch is in the o-po- sition before connecting to power source and/or battery pack, pick- ing up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents. d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left at- tached to a rotating part of the power tool may result in personal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. . f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewel- lery or long hair can be caught in moving parts.. g) If devices are provided for the con- nection of dust extraction and col- lection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust- related hazards.

4) POWER TOOL USE AND CARE

a) Do not force the power tool. Use the correct power tool for your ap- plication. The correct power tool will do the job better and safer at the rate for which it was designed. b) Do not use the power tool if the switch does not turn it on and o. Any power tool that cannot be con-33

trolled with the switch is dangerous and must be repaired. c) Disconnect the plug from the pow- er source and/or the battery pack from the power tool before making any adjustments, changing acces- sories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool ac- cidentaIly. d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to oper- ate the power tool. Power tools are dangerous in the hands of untrained users. e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may aect the power tool’s operation. If damaged, have the power tool repaired be- fore use. Many accidents are caused by poorly maintained power tools. f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less Iikely to bind and are easier to control. g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations dier- ent from those intended could result in a hazardous situation.

a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

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 white operating chain saws may cause entanglement of your cloth

ing or body with the saw chain. b) 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. c) Wear safety glasses and hear- ing protection. Further protective equipment for head, hands, legs and feet is recommended. Adequate protective clothing will reduce per- sonal injury by flying debris or acci- dentaI contact with the saw chain. d) Do not operate a chain saw in a tree. Operation of a chain saw white up in a tree may result in personal in jury. e) Always keep proper footing and operate the chain saw only when standing on fixed, secure and level surface. Slippery or unstable sur- faces such as ladders may cause a loss of balance or control of the chain saw. f) When cutting a Iimb that is under tension be alert for spring back. When the tension in the wood fibres is released the spring loaded Iimb may strike the operator and/or throw the chain saw out of control. g) Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and34

for outdoor use. The wire cross sec- tion of the mains cable must be at least 2.5 mm

. Always roll out the ca- ble reel completely before use. Check the mains cable for damages.

Beware of kickback! Be care- ful of kickback of the machine during work. There is danger of injury here. You can avoid kick- backs by exercising caution and using a correct sawing tech- nique. Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclu- sively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury. Kickback is the result of tool misuse and/ or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: a) Maintain a firm grip, with thumbs and fingers encircling the chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. be whipped toward you or pull you o balance. h) Carry the chain saw by the front handle with the chain saw switched o 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 Iikelihood of accidentaI contact with the moving saw chain.

i) Follow instructions for lubricating,

chain tensioning and changing ac- cessories. Improperly tensioned or lubricated chain may either break or increase the chance for kickback. k) Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control.. l) 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 dierent than intended could result in a haz- ardous situation. m) Hold the power tool only on the insulated handle surfaces, as the saw chain can come into contact with concealed power lines or the mains cable to the equipment. Contact between the saw chain and a live wire can make metal parts of the equipment live and cause an electric shock. n) If the supply cord of this power tool is damaged, it must be replaced by a specially prepared cord available through the service organization. o) Use only approved mains cables of the type H07RN-F that are intended35

Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chain saw b) Do not overreach and do not cut above shoulder height. This helps pre- vent unintended tip contact and enables better control of the chain saw in unex- pected situations.. c) Only use replacement bars and chains specified by the manufac- turer. Incorrect replacement bars and chains may cause chain breakage and/or kickback. d) Follow the manufacturer´s sharpen- ing and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to in- creased kickback.

Even if properly operating and handling this electric tool, some residual risks will remain. Due to its construction and build, this electric tool may present the following hazards: a) Lung damage, if suitable respiratory protection is not worn; b) Cuts c) Ear damage if working without ear protection. d) Damage to your health caused by swinging your hands and arms when operating the appliance for longer periods of time or if the unit is not held or maintained properly. Warning! During operation, this electric tool generates an elec- tromagnetic field which, under certain circumstances, may impair the functionality of active or passive medical implants. To reduce the risk of serious or le- thal injuries, we recommend that persons with medical implants consult their doctor and the manufacturer of their medical implant before operating the ma- chine. Safety functions 1 Rear grip with hand guard Protects the hand against branch- es and boughs in the case of springing away by the chain. 4 Chain braking lever/hand guard Control system, which stops the saw chain immediately in case of a spring-back; lever can also be activated manually; protects the left hand of the operator if it slides from the front grip. 6 Saw chain with small spring- back Helps you to catch spring-backs with specially developed control systems. 8 Metal stop claw Reinforces the stability when vertical cuts are carried out and facilitates sawing. 10 Electric motor Double insulated for safety rea- sons. 11 On-o switch with safety chain brake On releasing the On/O switch, the device immediately switches

Operation startup Always wear protective gloves when working with the chainsaw and employ only original parts. Pull out the power plug before doing any work on the chainsaw itself -– injury hazard! Before initial operation of the electric chainsaw, you must assemble the blade, chain and chain wheel cover, adjust the chain, fill with chain oil, check the func- tion of the chain brake and check the oil mechanism. Caution! The saw can re-oil. Please note that the saw re-oils after use and oil may leak out if it is stored on its side or on the head. This is a normal process due to the necessary ventilation opening on the upper edge of the tank and does not constitute a reason for complaint. As each saw is checked during production and test- ed with oil, a small residue may be in the tank despite draining, which may slightly dirty the housing with oil in transit. Please clean the housing with a cloth. Assemble the blade and the saw chain

1. Place the saw on a flat surface.

2. Loosen the mounting nuts

14) and take o the chain

(20) in an anticlockwise direc- tion until the chain tensioner pin (21) is located in the stop posi- tion in the direction of the saw.

4. Spread the saw chain (6) in a

loop, so the cutting edges face clockwise.

5. Place the chain around the bla-

de (5) and into the blade groove. Form a loop in the blade (5) with the surplus chain elements on the side of the holes (24).

6. Fix the inserted chain on the

blade using your gloved hand. Now place the chain around the chain sprocket (27).

7. Place the chain bar (5) and saw

chain (6) on the bar bolts (22). When the nose on the right be- low the bar bolt (21) sits in the round (24) recess on the blade, the blade is placed correctly. It is normal for the saw chain (6) to sag.

8. Put on the sprocket chain wheel

covering (15). When doing so, first the lug (25) on the covering has to be inserted into the notch on the appliance (26).

9. Screw on the cover with the

mounting nuts (14). The chain must not slide o from the blade in the process. Tighten the nut only hand-tight, as the chainsaw must still be tensioned. Tensioning the saw chain With a correctly tensioned chain you get good cutting performance and a longer life. An incorrectly tensioned chain may break or spring o, lead- ing to danger of injury. Test the electric saw before every start and the chain tension after every hour of sawing The chain is correctly tensioned if it does not sag at the rail underside and can be rotated completely around with the gloved hand.37

• Check the oil level indicator (2) re- gularly and top up with oil once the lowest mark is reached. The oil tank holds approx. 270 ml oil.

• Use Deltafox bio-oil; this product contains additives that reduce wear and tear and does not damage the pump system. bio-oil is available from our Service-Center.

• If you have no Deltafox bio-oil avail- able, use chain lubrication oil with low adhesive additive content.

1. Unscrew the oil fill cap (3) and fill

2. Wipe o any spilled oil and close

the cap again. Operating the chainsaw Switch on the chainsaw only when chain bar, saw chain and sprocket chain wheel covering are correctly assembled. Ensure the voltage of the mains connection agrees with the la- bel on the device. Make sure you have a secure stance. Before starting, ensure that the electric chainsaw is in contact with no objects. Switching on Check before the start, whether sucient chain oil is in the tank and, if necessary, refill with chain oil (see Chapter Operation Start). When the saw chain is tensioned with 9 N (approx. 1 kg), the gap between the saw chain and the guide rail may not be more than 2 mm.

1. Ensure that the chain brake has

been released, that is, that the chain brake lever (4) is pulled up against the front grip.

2. Loosen the mounting nuts (14).

3. To tension the saw, twist the

chain tensioner screw (20) in a clockwise direction. To loosen the tensioning, twist the chain tensioner screw (20) in an anti-clockwise direction.

4. Tighten the mounting nuts (14)

firmly. With a new saw chain, you must readjust the chain tension after at least 5 cutting operations. Chain lubrication The rail and chain must never be without oil. If you operate the electric chainsaw with too lit- tle oil, the cutting performance and the lifetime of the saw chain is reduced, since the chain becomes blunt faster. You can identify a case of too little oil where smoke development or discoloration of the rail occurs. The power saw is equipped with an oil automatic system. As soon as the motor is speeded up, the oil also flows faster to the chain bar.38

1. Release the chain brake, where

you shift the brake arm (4) back against the front grip.

2. Form a loop from the end of the

extension cable and hang this into the tension relief (19) on the rear grip.

3. Connect the device to the mains

4. Hold the electric chainsaw firmly

with both hands, with the right hand on the rear grip and the left hand on the front handle. Thumb and finger must close securely over the handles.

5. For switching on, activate the

switch-on block (12) with the right thumb and then press the On/ O switch (11), the electric power saw runs with highest speed. Release the switch-on block again.

6. The power saw switches o

when you release the On/O switch again. Switching for con- tinuous running is not possible Checking the chain brake The saw chain does not turn if the chain brake is engaged.

1. Release the chain brake by

shifting the brake arm (4) over against the front grip.

2. Place the electric chainsaw onto

a solid, flat surface. It must not contact any objects.

3. Connect the device to the mains

4. Hold the electric chainsaw firmly

with both hands, with the right hand on the rear grip and the left hand on the front handle. Thumb and finger must close securely over the handles (see

5. Turn on the electric chainsaw.

(See “Switching On”).

6. Activate the chain braking lever

(4), with running motor, with the left hand. Chain should stop abruptly..

7. Once the chain brake is work-

ing properly, release the on/o switch and the chain brake. If the chain brake does not func- tion correctly, you must not use the electric chainsaw. A slack saw chain leads to danger of in- jury. Return the electric chainsaw to our Service-Center for repair Checking the oil automatic system Check the oil level and the oil automatic system before commencement of work.

• Switch on the chainsaw and hold it above a bright background. The saw must not touch the ground. If an oil trace can be seen, the chainsaw is working trouble-free. Oils can become viscous in cold weather. If no trace of oil appears, it may be necessary to clean the oil out- let channel or to have the electric chainsaw repaired by our cus- tomer service.39

If the saw chain jams, you do not attempt to pull out the electric chainsaw using power. There is a danger of injury here. Switch o the motor and use a lever or wedge to free the elec- tric chainsaw. Bucking This refers to sawing up a felled tree trunk into smaller sections. Cutting to length means sawing felled tree trunks into small sections. Ensure that you have secure foo- ting and balance your body weight evenly on both feet. If possible, the trunk should be protected and supported by branches, logs or wedges.

• Ensure that the saw chain does not come in contact with the ground dur- ing sawing.

• Make sure you have a secure stance and, in the case of sloping ground, stand above the log.

1. Log is lying on the ground:

Saw through the log completely from above and ensure at the end of the cut not to contact the ground. If you can turn the tree trunk, saw two-thirds of the way through it. Then turn the trunk around and saw the rest of the way through from above.

2. Log is supported at one end:

Start sawing from the bottom and work your way up (with the upper edge of the bar) a third of the way into the diameter of the trunk to prevent splitting. Then saw from the top downwards Sawing techniques General Observe the noise protection and local regulations when cutting wood. Local requirements may require a suitability test. Ask the forestry commission.

• Lay the connecting lead such that it will not be caught on branches or similar during sawing.

• For each cut, apply the claw stop se- curely and only then start sawing.

• You have better control when you saw with the bottom side of the chain bar (with pulling saw chain) and not to with the top side of the chain bar (with pushing saw chain).

The saw chain must not contact either the ground or another object during sawing through or after sawing comple

• Make sure that the saw chain does not become jammed in the wood. Do not let the tree trunk break or split o.

• Consider also the precautions against spring-back (see notes on safety).

• For sawing work on a slope, always stand above the tree trunk. To keep control at the moment of “sawing through”, reduce the contact pressure at the end of the cut without loosen- ing the firm grip on the chainsaw handles. Ensure that the saw chain does not come into contact with the ground. After completing the cut, wait for the chainsaw to come to a stand- still before removing the chainsaw. Always switch o the chainsaw motor before moving from one tree to an- other.40

with the lower edge of the bar towards the first cut to prevent the bar from becoming jammed in the wood..

3. Log is supported at both ends:

Start from the top and work down (with the lower edge of the bar) to a third of the diameter of the trunk. Then saw from under- neath with the upper edge of the bar until the two cuts meet.

4. Sawing on a sawhorse:

Hold the electric chainsaw steady with both hands, keeping the saw in front of you while sawing. Once the saw is through the wood, guide the machine passed you on the right (1). Hold your left arm as straight as you can (2). Watch out for the falling trunk. Position your- self to prevent any danger from the separated trunk. Watch your feet. The trunk may cause injuries when falling. Keep your balance (3). Limbing Limbing is the designation for the sawing o of branches and boughs from a felled tree. Many accidents occur during the removal of branches. Never cut tree limbs when you are standing on the log. Keep the spring-back area in mind if branches are un- der tension.

• Do not remove support branches until after the sawing o.

• Branches under tension must be sawed from below to above, in order to prevent jamming of the chainsaw. When working on thicker branches, use the same technique as when you are sawing up a felled trunk.

• Work to the left of the log and as near as possible to the electric chainsaw. As far as possible, the weight of the saw should rest on the log.

• Change position to saw o branches on the other side of the trunk.

• Branches sticking out are cut o separately.

• When taking o larger branches, lea- ve the ones that extend downwards and support the tree be for now. Saw o smaller branches, as shown in Fi- gure , in one go. Felling trees A lot of experience is necessary in felling trees. Cut down trees only when you can safely han- dle the electric chainsaw. In no case should you use the elec- tric chainsaw if you feel unsure about anything.

• Ensure that no people or animals are in the field of action. The safety dis- tance between the tree to be felled and the nearest-located workplace must be 2 ½ tree lengths.

• Note the felling direction: The user must be able to move safely near the felled tree, to saw o the tree easily and remove branches.It is to be avoided that the felled tree snags itself on another tree. Note the natural felling direction, which is dependent on the slope and curvature charac- teristic of the tree, wind direction and the number of branches.

• In the case of sloping ground, stand above the tree to be felled.

• Small trees, with a diameter of 15-41

18cm, can usually be sawn o with one cut.

• In case of trees with a larger diameter, a notched cut and a back cut must be implemented (see below).

• If cutting and felling is being carried out by two or more persons simul- taneously, the distance between the felling and cutting persons must be at least twice the height of the tree to be fellled. When felling trees, ensure that no other persons are subject to hazards and that no material damage is caused. If a tree should come into contact with a power line, the supply company must be informed immedi- ately.

• Dirt, stones, loose bark, nails, clips and wires must be removed from the tree. Do not fell any trees when a strong or changing wind is blowing, if the danger of prop- erty damage exists or if the tree could fall on electric wires. Immediately after termination of the sawing procedure, remove the ear protection so that you can hear hooter and alarm sig- nals.

1. Removal of branches:

Remove hanging branches by positioning the cut from above the branch. With removal of branches, never work higher than shoulder level.

Remove the undergrowth around the tree to ensure an easy escape. The escape area (1) should be around 45° either side behind the planned felling direction (2).

3. Cutting notch (A):

Make a felling notch in the direc- tion in which you wish the tree to fall. Start with an upper saw- ing cut. Now make a sawcut below, which runs horizontally and en- counters the upper sawcut exactly. The depth of cut of the notch should be approx. 1/3 of the trunk diameter and the cutting angle at least 45°. Never step in front of a tree which is notched.

Felling back cut (B): Make the back cut from the other side of the log, where you stand to the left of the log and saw with the chainsaw pulling. The back cut must run horizon- tally not less than 5cm above the horizontal notched cut. The back cut should be so deep that the separation distance between the back cut and the notch cutting line is at least 1/10 of the trunk diameter. The part of the log not sawed through is designated as a break dimen- sion

Slide a cutting wedge or crow- bar into the felling cut as soon as the cutting depth so permits, in order to prevent the blade from getting jammed. When the felling cut nears the hinge, the tree should begin to fall. If it becomes apparent that the tree might not fall into the desired42

direction or if it bends back, and if the chainsaw is stuck, dis- continue the felling cut and use wooden, plastic or aluminium wedges to open the cut and fell the tree to fall into the desired fall line.

5. If the trunk diameter is larger

than the length of the chain bar, make two cuts. For safety reasons, we advise in- experienced users not to fell any logs with a rail length which is smaller than the trunk diameter.

After carrying out of the back cut, the tree falls by itself or with the aid of the felling wedge or crowbar.

As soon as the tree begins to fall, pull out the saw from the section, stop the motor, place the electric chainsaw down and leave the workplace using the withdrawal path. Be completely aware of the fall- ing cut material Maintenance and cleaning Basically, carry out mainte- nance and cleaning works with switched-o motor and power plug removed. Danger of injury! Leave any maintenance and ser- vicing work not covered by this manual to our Service-Center. Use only original spare parts. Allow the machine to cool down before all maintenance and cleaning works. Danger of burn injuries! Maintenance intervals Regularly carry out the maintenance operations listed in the following table. The life of the saw is extended by regular maintenance of your chainsaw. Furthermore, you get optimum cutting performance and avoid accidents. Maintenance Interval Table Machine part Action Before every use After 10 hours of operation Components of the chain brake Check, replace if required

• Clean the machine thoroughly after every use. In this way, you extend the life of the machine and avoid accidents.

• Keep the gripping handles free of gas, oil or grease. Clean the gripping han- dles, where appropriate, with a moist cloth soaked in soap. Use no solvents or gas for cleaning!

• Clean the saw chain after every use. Use a paint brush or whisk for that. Do not use any liquids to clean the chain. After cleaning, oil the chain lightly with chain oil.

• Clean the ventilation slots and the surfaces of the machine with a paint brush, whisk or dry cloth. Do not use any liquids for cleaning.. Oiling the saw chain Clean and oil the chain regularly. In this way, you keep the chain sharp and get optimum machine performance. In case of damage due to inadequate maintenance of the saw chain, the guarantee claim is invalid. Remove the power plug and use cut-protection gloves when you are handling the chain or the chain bar.

• Oil the chain after cleaning, after 10 hours of use or at least once weekly, depending on which comes first.

• Before oiling, the chain bar must be cleaned thoroughly, in particular the teeth of the rail. Use a whisk and a dry cloth for that.

• Oil the individual chain links with the aid of an oil suction gun with pinpoint tip (available in the specialist trade). Place individual oil drops onto the ar- ticulated links and onto the tooth tips of the individual chain links. Sharpening the saw chain An incorrectly sharpened saw chain increases the danger of spring-back! Use cut-protection gloves when you are handling the chain or the chain bar. A sharp chain guarantees an op- timal cutting performance. It eats eortlessly through the wood and leaves large, long wooden chips. A saw chain is blunt if you have to press the cutting equipment through the wood and the wood

en chips are very small. In the case of a very blunt saw chain, no chip cuttings result at all, only sawdust.

• The sawing parts of the chain are the cutting elements, which consist of a cutting tooth and a depth limiting pro

jection. The vertical separation distance between these two determines the sharpness depth.

• The following values must be noted in sharpening the cutting teeth: - Sharp edge angle (30°) - Breast angle (85°) - Sharpness depth (0.65 mm) - Round file diameter (4.0 mm)44

Deviations from the measure- ment data of the cutting geom- etry can lead to an increase of the spring-back slope of the machine. Increased danger of accident! Special tools are necessary for sharpen

ing the chain, which guarantee that the cutting edges are sharpened at the cor

rect angle and to the correct depth. For the inexperienced user of chainsaws, we recommend to have the saw chain sharpened by a specialist or a specialist workshop. If you think yourself capable of sharpening the chain, you can acquire the special tools in the specialist trade.

1. Switch the saw o and unplug it from

2. Remove the saw chain (refer to the

section on operating the saw). The chain should be well-tensioned to en

sure proper sharpening.

3. For the sharpening, a round file with

4.0 mm diameter is necessary.

Other diameters damage the chain and can lead to danger during work!

4. Sharpen only from the inside to the

outside. Guide the file from the inner side of the cutting teeth to the outer side. Lift the file when you are with- drawing it.

5. Sharpen first the teeth on one side.

Turn the saw around and sharpen the teeth of the other side.

6. The chain is worn and must be re-

placed by a new saw chain if only approx. 4 mm of the cutting teeth is remaining.

7. After the sharpening, all cutting ele-

ments must now be equal in length and width.

8. After every third sharpening, the

sharpness depth (depth limitation) must be checked and the height filed with the aid of a flat file. The depth limi- tation should be set back about 0.65 mm from the cutting tooth. After the setting back of depth limitation, round it o a little at the front. Adjusting the chain tension The adjustment of the chain tension is described in the chapter: Starting opera- tion, tensioning chainsaw.

• Switch o the saw and pull out the power plug.

• Check the chain tension regularly and adjust as often as possible. When pulling on the saw chain with 9 N (approx. 1 kg) tensile force, the saw chain and blade must have a gap of no more than 2 mm. Starting up a new saw chain In the case of a new chain, the tensioning force decreases after some time. There- fore you must re-tension the chain after the first 5 cuts and at longer intervals after this. Never attach a new chain to a worn drive pinion or place onto a damaged or worn chain bar. The chain could spring back or break, potentially leading to seri

Maintaining the chain bar Use cut-protection gloves when handling the chain or the chain bar. The blade must be inverted every 8-10 working hours in order to guarantee even wear (see chapter “initial operation”).

1. Switch o the saw and pull out the

covering, the saw chain and the chain bar.

3. Check the chain bar for wear. Re-

move burrs and straighten the guide surfaces with a flat file.

4. Clean the oil passages (

chain bar, in order to guarantee a trouble-free, automatic oiling of the saw chain during operation.

5. Mount chain bar, chainsaw and

sprocket chain wheel covering and tighten the chainsaw. With the oil nozzles in good condition and the oil regulator set correctly, the saw chain will spray a little oil o after starting. Storage

• Clean the equipment before putting it away.

• Empty the oil tank before longer peri- ods of non-use. Dispose of waste oil environmentally correctly (see „Waste disposal and environmental protec- tion“).

• Put on saw bar protection sheath.

• Store the appliance in a dry place well out of reach of children. Waste disposal and environmental protection Do not dispose of used oil in the sewage system or drains. Dispose of used oil in an environmentally correct manner - bring it to a waste disposal center. Be environmentally friendly. Return the tool, accessories and packaging to a recy

cling centre when you have finished with them. Machines do not belong with domestic waste. Empty the oil tank carefully and hand in your electric chainsaw at a disposal center. The plastic and metal parts em- ployed can be separated out and thus re- cycled use can be implemented. Ask our Service-Center for details. We dispose of your defective devices free of charge.46
