WARNING! Read all safety warnings and all in- structions. Failure to follow the warnings and in- structions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or bat- tery-operated (cordless) power tool.

3.1.1 Work area safety

Keep work area clean and well lit. Clut- tered and dark areas invite accidents.

Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

3.1.2 Electrical safety

Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of elec- tric shock.

Avoid body contact with earthed or grounded surfaces such as pipes, radia- tors, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

When operating a power tool outdoors, use an extension cord suitable for out- door use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

If operating a power tools in a damp loca- tion is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3.1.3 Personal safety

Stay alert, watch what you are doing 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, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

Use personal protective equipment. Al- ways wear eye protection. Protective equip- ment such as a dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce person- al injuries.

Prevent unintentional starting. Ensure the switch is in the off-position before con- necting to power source and/or battery pack, picking up or carrying the tool. Car- rying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.

Remove any adjusting key or wrench be- fore turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

Do not overreach. Keep proper footing and balance at all times. This enables bet-GB 38 CS 4235 Safety instructions ter control of the power tool in unexpected situations.

Dress properly. Do not wear loose cloth- ing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of these devices can reduce dust- related hazards.

3.1.4 Power tool use and care

Do not force the power tool. Use the cor- rect power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.

Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjust- ments, changing accessories, or storing power tools. Such preventive safety mea- sures reduce the risk of starting the power tool accidentally.

Store idle power tools out of the reach of children and do not allow persons unfa- miliar with the power tool or these instruc- tions to operate the power tool. Power tools are dangerous in the hands of untrained users.

Maintain power tools. Check for misalign- ment or binding of moving parts, break- age of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

Keep cutting tools sharp and clean. Prop- erly maintained cutting tools with sharp cut- ting edges are less likely to bind and are eas- ier to control.

Use the power tool, accessories and tool bits etc. in accordance with these instruc- tions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazard- ous situation.

3.1.5 Battery tool use and care

Recharge only with the charger specified by the manufacturer. A charter that is suit- able for one type of battery pack may create a risk of fire when used with another battery pack.

Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

When battery pack is not in use, keep it away from other metal objects, lie paper- clips, coins, keys, nails, screws or other small metal objects, that can make a con- nection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected form the battery may cause irritation or burns.

Have your power tool serviced by a quali- fied repair person using only identical re- placement parts. This will ensure that the safety of the power tool is maintained.

3.2 Chain saw safety warnings

Keep all parts of the body away from the saw chain when the chain saw is operat- ing. Before you start the chain saw, make sure the saw chain is not contacting any- thing. A moment of inattention while operat- ing 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 in- creases 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 contact- ing 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 protec- tion. Further protective equipment for head, hands, legs and feet is recommend- ed. Adequate protective clothing will reduce469892_a 39 Safety instructions personal injury by flying debris or accidental contact with the saw chain.

Do not operate a chain saw in a tree. Oper- ation 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 load- ed 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 con- tact with the moving saw chain.

Follow instructions for lubricating, chain tensioning and changing accessories. Im- properly 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 slip- pery 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, ma- sonry or non-wood building materials Use of the chain saw for operations different than intended could result in a hazardous situa- tion.

3.3 Causes and operator prevention of

kickback 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 exclusively 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 incor- rect operating procedures or conditions and can be avoided by taking proper precautions as given below:

Maintain a firm grip, with thumbs and fin- gers encircling the chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precau- tions are taken. Do not let go of the chain saw.

Do not overreach and do not cut above shoulder height. This helps prevent unin- tended tip contact and enables better control of the chain saw in unexpected situations.

Only use replacement bars and chains specified by the manufacturer. Incorrect re- placement bars and chains may cause chain breakage and/or kickback.

Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

Only work in sufficient daylight or artificial lighting.

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

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

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.

Prior to the first use, at the very least practice cutting round wood on a saw frame or stand.

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

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

3.6.2 Operating times

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

3.6.3 Vibration load

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

Is the appliance being used as in- tended?

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

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

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

Only operate the tool at the motor speed re- quired for the respective work. Avoid using the maximum speed in order to reduce noise and vibrations.

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

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

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

Take long breaks during your working day so you can recover from the noise and the vibra-GB 42 CS 4235 Safety instructions tions. Plan your work in such a way that the use of appliances that generate strong vibra- tions is spread over several days.

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

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

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

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

3.6.4 Noise pollution

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

3.6.5 Working with the chain saw

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

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

Before each use, perform a visual inspection in order to check that the chain saw is complete and does not contain damaged or worn compo- nents. Safety and protective devices must be intact. WARNING! Risk of injury due to chain saw being started inadvertently A chain saw that is started inadvertently can lead to serious injury. Therefore, re- move the rechargeable battery during:

Danger of serious injury. Serious injury can be caused if there are damaged components on the chain saw.

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

5.1 Charging the rechargeable battery (06,

07) CAUTION! Danger of fire during charging! Due to heating of the charger, there is a danger of fire if it is placed on an inflam- mable surface and is not adequately ventilated.

Always use the charger on a non-in- flammable surface or in a non-com- bustible environment.

If available: Keep the ventilation slots free. NOTE Fully charge the rechargeable battery before using it for the first time. The re- chargeable battery can be charged in any charge status. Interrupting charging does not damage the rechargeable bat- tery. NOTE When charging, the rechargeable bat- tery is protected from overcharging due to automatic detection of the charge sta- tus and thus can remain connected to the charging unit for some time, but not permanently. NOTE Heed the separate operating instructions for the rechargeable battery and for the charging unit.

1. Connect rechargeable battery (06/1) to char-

ger (06/2, 06/a), and charger (06/3, 06/b) to the mains voltage. The charging process be- gins. The LED on the charging unit lights green, the charge status is displayed on the rechargeable battery.

chargeable battery (07). The charging pro- cess takes approx. 2.5hours until fully charged. The charging process ends auto- matically when the rechargeable battery is fully charged.

3. Disconnect the rechargeable battery from

charger (06/a) and the charger from the mains voltage (06/b).

5.2 Filling saw chain oil (08)

IMPORTANT! Danger of damaging the chain saw The chain saw will be severely damaged if there is too little or even no saw chain oil in the tank or if it has dried/is sticky. Dried/sticky saw chain oil can lead to damage to oil-channelling components and the oil pump. Damage also occurs if used oil is used. The use of used oil leads to environmen- tal damage!

For start-up work, fill saw chain oil into the tank.

Each time before changing the re- chargeable battery at the latest, fill the tank with saw chain oil again. The saw chain and the guide rail are continuously supplied with oil during operation by means of an automatic oiler system. The saw chain oil pro- tects against corrosion and premature wear. There must always be sufficient saw chain oil in the tank to lubricate the saw chain sufficiently. Use only environmentally friendly, biodegradable, high-quality saw chain oil for lubrication of the saw chain and guide rail. This oil must be trans- ported and stored in approved and appropriately labelled containers. Each time before starting work or changing the rechargeable battery, check the oil level and re- plenish the saw chain oil if necessary:

1. Check the oil level in the viewing aperture of

the tank (08/1). It must always be possible to see oil. The minimum and the maximum oil level must not be exceeded.

5.3 Function test of the chain brake

The chain saw has a manual chain brake that is triggered by the chain brake bracket, for example if kickback occurs. If the chain brake is tripped, saw chain and motor are stopped immediately. DANGER! Danger of fatal injury as a result of negligent handling! Extremely serious injury and even fatal injury can be caused as a result of care- less and unexpected movements of the chain saw.

Pay attention to safety and work with a high level of concentration when using the chain saw.

Do not press any switch when re- leasing the chain brake. WARNING! Danger of fatal injury and danger of extremely severe injury due to a de- fective 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 be- fore 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.

7 WORKING BEHAVIOUR AND

WORKING TECHNIQUE NOTE Courses in the use of chain saws and techniques for felling trees are regularly held by various forestry organisations. DANGER! Danger of fatal injury due to inade- quate technical knowledge! Inadequate technical knowledge can re- sult in extremely serious up to fatal inju- ry!

Only trained and experienced peo- ple are allowed to fell trees and lop branches.GB 48 CS 4235 Working behaviour and working technique DANGER! Danger of fatal injury from splintered wood! Wood chips caught up in the chain can cause extremely serious and even fatal injury!

Remove loose chips and wood splin- ters from the part to be sawn.

7.1 Felling trees (19, 20)

Observe the following points before and during felling operations:

When felling trees, care must be taken to en- sure that other persons are not exposed to danger, that no supply lines are connected and that no damage to property is caused. If a tree comes into contact with a supply line, the utility company must be informed immedi- ately.

Also pay attention to other people's property, animals or objects. These must not be in the danger zone. Immediately notify the owner in case of damage.

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

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

Natural lean of the tree

The position of larger branches

Branches growing on one side

Level ground or slope

Asymmetrical growth, wood damage

Wind direction and wind speed

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

Establish your escape route in advance, and make sure that there are no obstacles in the way. The escape route should be at an angle of approx. 45° backwards from the falling di- rection (19).

The trunk must be free from growth, branch- es and foreign bodies (e.g. dirt, stones, loose bark, nails, staples, wire, etc.). Make two undercuts and one back cut in order to fell 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 (20/C) horizontally,

then the second undercut at an angle of at least 45° from above. This prevents the chain saw becoming trapped when you make the second undercut. The undercut must be as close as possible to the ground and in the re- quired felling direction (20/E). The depth of the undercut should be about 1/4 of the diam- eter of the trunk.

3. Cut the back cut (20/D) exactly horizontally

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

4. Saw in the back cut (20/D) sufficiently deep

so that a bridge (20/F) of at least 1/10 the trunk diameter remains between the undercut (20/C) and the back cut (20/D). This bridge prevents the tree from twisting and falling in the wrong direction. The tree should start to fall when the back cut (20/D) approaches the bridge (20/F). Do not saw through the bridge! 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 made of wood, plastic or aluminium in the direc- tion of the required felling line.

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

Walk away in the direction of the escape route.

Watch out for falling branches and twigs.

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

to the back cut in order to cause it to fall in a controlled way. Note:Use only wedges made of wood, plas- tic or aluminium.

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

move your ear defenders and listen out for signals or warning calls. Only experienced or trained people should make plunge cuts, longitudinal cuts and boring cuts (20).469892_a 49 Working behaviour and working technique DANGER! Danger of fatal injury from a falling tree! Having no escape route when felling a tree represents a danger of serious and even fatal injury!

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

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

Do not carry out any felling work in windy conditions.

Delimbing is the separation of branches from the felled tree. Observe the following points:

Support the chain saw against the tree trunk with the bumper spike during the work.

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

Cut off smaller branches with one cut.

Saw off branches systematically and sequen- tially from the tree (21/a). First, saw off any branches that might hinder you. Then cut off the branches that create tension. Finally saw off the main branch at the base.

Saw off free-hanging branches from above (21/b), but not from below.

Pay attention to branches under tension, and saw through these from underneath upwards (21/c) in order to avoid the chain saw becom- ing trapped.

7.3 Cross-cutting (22 – 25)

Cutting to length means dividing the felled tree in- to sections. Observe the following points:

Ensure that your feet are stable and that your body weight is evenly distributed over both feet. If possible, the trunk should be backed and supported by branches, beams or wedg- es.

When working on a slope, always stand uphill from the tree trunk, because it could roll away (22).

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

Position the bumper spike directly adjacent to the cut edge and allow the chain saw to pivot about this point. Do not exert any pressure at the end of the cut.

In order to maintain full control of the chain- saw at the moment of sawing, reduce the contact pressure towards the end of the cut without releasing the tight hold on the chain- saw handles.

Make sure that the saw chain does not touch the ground.

At the end of the cut, wait for the saw chain to come to a halt before you remove 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 (23/ a), without cutting into the ground. 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 (24/a), then saw through the remainder from above, down as far as the cut made from underneath (24/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 (25/a), then saw through the remainder from underneath, up as far as the cut made from above (25/b). DANGER! Danger of fatal injury due to kick- back! The operator can be fatally injured by kickback of the appliance.

It is essential to comply with the measures in order to avoid any kick- back.GB 50 CS 4235 Maintenance and care

7.4 Cutting converted timber

Heed the following points during this work:

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

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

Secure logs to prevent them twisting.

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

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

8 MAINTENANCE AND CARE

WARNING! Danger of cutting injuries Danger of cutting injuries when reaching into sharp-edged, moving appliance parts and into cutting tools.

Before maintenance, care and cleaning work, always switch off the appliance. Remove the recharge- able battery.

Always wear protective gloves during maintenance, care and clean- ing work. The chain saw complies with all relevant safety standards. Repairs are only allowed to be per- formed by qualified specialists, and with the ex- clusive use of genuine spare parts.

After each use, check the chain saw for wear and renew any damaged components.

Do not get the machine wet or expose it to moisture. Clean plastic parts with a cloth and do not use any cleaning agents or solvents.

Clean the cooling air slots if they are blocked.

Do not spray the chain saw not with water and do not use a high-pressure cleaner.

8.1 Checking the chain tension

Frequently check the chain tension, because new saw chains stretch. At operating temperature, the saw chain stretch- es and hangs down. NOTE The saw chain has been tensioned cor- rectly when:

It is in contact with the underside of the guide rail and can be pulled through by hand

It can be lifted by 3 – 4 mm in the middle of the guide rail CAUTION! Danger of injury due to the saw chain jumping off! An insufficiently tensioned saw chain can jump off during operation and lead to injury.

Frequently check the chain tension. The chain tension is too low if the drive links come out of the groove on the underside of the chain bar.

Re-tension the saw chain properly if the chain tension is too low.

8.2 Sharpening the saw chain (26)

DANGER! Danger of fatal injury due to kick- back! The operator can be fatally injured by kickback of the chain saw.

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

The saw chips are like sawdust.

Greater force is necessary for cutting.

The cut is not straight.

Vibration 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 adapted469892_a 51 Maintenance and care to the specific chain type (see chapter 8.6 "Chain maintenance table", page51). A certain amount of skill and experience is necessary to avoid damage to the teeth. To sharpen the saw chain:

1. Switch off the chain saw and remove the re-

2. Release the chain brake.

3. Clamp the guide rail with fitted saw chain in a

suitable vice, taking care that the saw chain can move freely.

4. Tension the chain if it is slack.

5. Place the file in the corresponding guide and

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

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

clusively in the forwards direction, then re- peat the working step on all teeth in the same orientation (right or left).

7. Reverse the position of the guide rail in the

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

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

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

9. After sharpening, clean away all filings and

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

The length of the teeth is less than 5 mm;

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

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

8.3 Cleaning the chain sprocket interior

Thoroughly clean the chain saw after each use.

1. Remove the rechargeable battery and place

the chain saw on a stable base.

2. Unbolt the cover of the chain sprocket.

3. Clean the inside with a suitable brush.

4. Remove the saw chain and take out the
