General notes

Read these safety instructions, these original instructions, the safety instructions provided with the battery pack, and the original instructions supplied with the battery pack/standard charger before using the device for the first time.

Act in accordance with them. Keep the booklets for future reference or for future owners.

In addition to the notes in the operating instructions, you also need to take into consideration the general safety regulations and accident prevention guidelines applicable by law.

Safety instructions

Working with chain saws poses a very high risk of injury, since you will be working with high chain speeds and very sharp saw teeth.

It is vital you observe the safety measures and code of behaviour for working with chain saws.

In addition to the safety warnings stated, the country-specific safety and training regulations (e.g. from authorities, trade associations or social insurance funds) also need to be observed. The use of chain saws may be restricted to certain times by local ordinances (time of day or time of the year). Observe the local regulations.

Hazard levels

DANGER

• Indication of an imminent threat of danger that will lead to severe injuries or even death.

WARNING

• Indication of a potentially dangerous situation that may lead to severe injuries or even death.

CAUTION

• Indication of a potentially dangerous situation that may lead to minor injuries.

ATTENTION

• Indication of a potentially dangerous situation that may lead to damage to property.

General Power Tool Safety Instructions

WARNING

- Read all safety warnings and all instructions.

Failure to follow the warnings and instructions 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 battery-operated (cordless) power tool.

1 Work area safety

a Keep work area clean and well lit. Cluttered or dark work areas invite accidents. b 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. c Keep children and bystanders away while operating a power tool.

Distractions can cause you to lose control.

2 Electrical safety

a 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 the risk of electric shock.

b Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There 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 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. e When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3 Personal safety

a 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.

b Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking 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 attached 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, jewellery or long hair can be caught in moving parts.

g If devices are provided for the connection of dust extraction and collection 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 application. 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 off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c Disconnect the plug from the power source and/or the battery pack from the

power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

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 operate 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 affect the power tool's operation. If damaged, have the power tool repaired before 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 likely 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 different from those intended could result in a hazardous situation.

5 Battery tool use and care

a) Recharge only with the chargers specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire. c) When the battery pack is not in use, keep it away from other metallic objects, like paperclips, coins, keys, nails, screws or other small metallic objects that can make a connection 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 from the battery may cause irritation or burns.

6 Service

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.

Additional General Safety Instructions

Note: Regulations may restrict the use of this device in some regions. Seek advice from your local authorities.

DANGER: Risk of fatal injury from cuts as a result of uncontrolled device movements. Keep body parts away from moving parts. Risk of injury from hurled or falling objects. Never use the device if there are persons, in particular children or animals, within a radius of 15 m. No changes may be made to the device.

WARNING: Children and persons unfamiliar with these instructions are not allowed to operate the device. The age of the operator may be limited by local restrictions. You need an unobstructed view of the work area in order to be able to recognise any potential dangers. Use the device only under good lighting conditions. Before operation, make sure that the device, all control elements including the chain brake and safety devices

are working properly. Check for loose locks, ensure that all protective devices and handles are correctly fitted and securely fastened. Only use the device when it is in a correct condition. Never use the device if the trigger on the handle does not switch on and off correctly. Replace any worn or damaged parts before operating the device. Risk of kickback due to loss of balance. Avoid an abnormal posture, keep a stable, safe footing and maintain your balance. Immediately stop the device and check for damage or identify the cause of the vibration if the device has been dropped, hit or vibrates abnormally. Have damage repaired by the authorised Customer Service or replace the device.

CAUTION: Wear full eye protection and hearing protection, strong and sturdy gloves and head protection when operating the device. Wear a face mask when the work is dusty.

• Wear long, heavy trousers, sturdy shoes, and well-fitting gloves when working with the device. Do not work barefoot. Do not wear any jewelry, sandals, or short trousers. Risk of injury when loose-fitting clothing, hair, or jewelry is caught by moving parts of the device. Keep clothing and jewelry

away from moving parts of the device. Tie long hair back.

• Hearing protection can impair your ability to hear warning sounds, so pay attention to hazards in your vicinity and in the work area. - Only use accessories and spare parts which are approved by the manufacturer. Only original accessories and original spare parts ensure that the appliance will run fault-free and safely.

Chain saw safety warnings

• Keep all parts of the body away from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating chain saws may cause entanglement of your clothing or body with the saw chain. Always hold the chain saw with your right hand on the rear handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.
• Hold the power tool by insulated gripping surfaces only, because the saw chain may contact hidden wiring

or its own cord. Saw chains contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

• Wear safety glasses and hearing protection. Further protective equipment for head, hands, legs, and feet is recommended. Adequate protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.
• Do not operate a chain saw in a tree. Operation of a chain saw while up in a tree may result in personal injury. Always keep proper footing and operate the chain saw only when standing on fixed, secure, and level surface. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the chain saw.
• When cutting a limb that is under tension, be alert for spring back. When the tension in the wood fibres is released, the spring-loaded limb may strike the operator and/or throw the chain saw out of control. Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be

whipped toward you or pull you off balance.

• Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chain saw, always fit the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
• Follow instructions for lubricating, chain tensioning, and changing accessories. Improperly tensioned or lubricated chain may either break or increase the chance for kickback.
• Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control.
• Cut wood only. Do not use chain saw for purposes not intended. For example: do not use chain saw for cutting plastic, masonry or non-wood building materials. Use of the chain saw for operations different than intended could result in a hazardous situation.

Causes and operator prevention of kickback

Kickback may occur when the nose or tip of the guide rail 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 rail up and back towards the operator.

Pinching the saw chain along the top of the guide rail may push the guide rail 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 incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

• 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. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chain saw.

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

• Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situations.
• Only use replacement bars and chains specified by the manufacturer. Incorrect replacement 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.

Additional safety instructions for chainsaws

Note: Karcher recommends sawing tree trunks on a sawhorse during first use. When using the chainsaw, keep a first aid kit for large wounds and a means of calling for help. A larger and more extensive first aid kit should be nearby.

Hold the chainsaw tightly with both hands. Hold the handles with your thumb on one side and your fingers on the other side. Hold the rear handle with your right hand and the front handle with your left hand. Risk of injury. Do not make any modifications to the device. Do not use the device to drive attachments or devices not recommended by the manufacturer.

• Before switching on the device, make sure that the saw chain does not touch any objects. Serious injuries or death can occur if a wrongly tensioned saw chain jumps out of the guide rail. Check the chain tension before each use. The length of the chain depends on the temperature. Ensure that all protective devices, handles, and bucking spikes are correctly fitted, securely fastened, and in good condition. Serious injuries can occur due to incorrect working methods:
• You need to be alert at all times and be in control of your workplace when working with the chainsaw. The size of the workspace depends on the task to be performed and the size of the tree or work piece. Felling a tree requires a larger workspace than, for example, trimming.
• Never saw with your body in line with the guide rail and chain. This reduces the danger

of being hit by the chain on the head or body during a kickback.

• Do not move the chainsaw back and forth but rather let the chain do the work. Keep the chain sharp and do not try to push the chain through the cut.
• Do not apply pressure to the saw at the end of the cut. Be prepared to relax the load on the saw when it has cut through the wood.
• Do not stop the chainsaw while sawing. Let the saw run until it has finished the saw cut.
• Familiarize yourself with your new chainsaw by making simple cuts in safely supported wood. Repeat this exercise if you have not used your chainsaw for a long time. - Do not saw vines and/or bushes with a diameter of less than 75 mm. - Switch the device off, lock the chain brake, remove the battery pack, and make sure that all moving parts have stopped moving:
• Before cleaning the device or removing a blockage.
• When leaving the device unattended.
• Before mounting or removing attachments. Before checking, maintaining, or working on the device.

CAUTION: The chainsaw is a heavy device. People who use the chainsaw should be physically fit and in good health. You should have good eyesight, agility, balance, and manual skills. In case of doubt, they should not use the chainsaw. When working with the device, always wear a safety helmet with a grille visor to reduce the danger of injury from a kickback into the face and head.

Residual risks

WARNING

• Certain residual risks remain present, even when the device is operated in the prescribed manner. The following dangers can be present when using the device: Vibration can cause injuries. Use the correct tools for the job, use the handles provided, and restrict the working time and hazard exposure time.
• Noise can cause hearing injuries. Wear hearing protection and limit the duration of exposure.
• Incision injuries on contact with exposed saw teeth of the saw chain.
• Incision injuries due to unforeseen, abrupt movements or kickback of the guide bar scabbard.
• Incision injuries / risk of injection by parts flying away from the saw chain. Injuries caused by hurled objects (wood shavings, splinters).
• Inhalation of dust and particles.
• Skin contact with the lubricant / oil.

Risk reduction

CAUTION

• Using the device for longer periods can cause poor circulation in the hands due to vibrations. A general period of use cannot be set, because this depends on several influencing factors:
• Personal tendency to suffer from poor circulation (frequently cold fingers, tingling sensation in the fingers)
• Low ambient temperature. Wear warm gloves to protect your hands.
• Holding the device too tightly hindering blood circulation.
• Continuous operation is more harmful than operation interrupted by work breaks. You should see a doctor if using the device regularly and for lengthy periods of time, and in the event of repeated occurrences of symptoms such as tingling in the fingers or cold fingers.

Safety devices

CAUTION

Missing or modified safety devices

Safety devices are provided for your own protection.

Never modify or bypass safety devices.

Chain with a low risk of kickback

A chain with a low risk of kickback reduces the likelihood of kickback.

The raked teeth (engagement blades) in front of each saw tooth prevent the saw teeth from engaging too deeply in the kickback zone, thus reducing the amount of kickback.

When grinding the chain, there is a danger that this safety function will be overridden. If the saw performance deteriorates, the chain should be replaced for safety reasons. For spare parts, use only the combination of guide rail and chain recommended by the manufacturer.

Guide rails

Guide rails whose tips have a small radius usually carry a lower risk of kickback.

Therefore use a guide rail with matching chain for the task, which is just long enough. Longer guide rails increase the likelihood of loss of control during sawing. Check the chain tension before each use (see chapter Checking the chain tension). If the chain tension is not set correctly, sawing smaller branches (thinner than the full length of the guide rail) increases the danger of the chain being thrown off.

Chain catcher

If the chain loosens or tears, the chain catcher prevents the chain from being thrown in the direction of the user.

Bucking spikes

The integrated bucking spikes can be used as a fulcrum to give the chain saw stability during a cut.

When sawing, press the device forward until the metal spikes penetrate the edge of the wood. Subsequently moving the rear handle up or down in the direction of the cut reduces the physical strain when working with the chainsaw.

Chain brake

Chain brakes are used in case of danger to bring the chain quickly to a standstill.

The chain must come to a standstill immediately when the hand guard/chain brake lever is pressed in the direction of the guide rail.

The chain brake cannot prevent kickback, but reduces the risk of injury if the guide rail hits the user in the event of a kickback.

The proper function of the chain brake must be checked before each use of the device (see chapter Checking the functionality of the chain brake).

Working techniques

Working position

DANGER

Uncontrolled movements of the chainsaw

Danger of death from incision injuries

Plan the cut before cutting and identify any potential dangers.

Always hold the chain saw firmly with both hands.

• Do not guide the chainsaw in the body axis.

Illustration O

• Carry the chainsaw at your side so that parts of your body do not get in the range of movement of the chainsaw.
• Keep as far away as possible from the sawed material.
• Never work on a ladder or standing in a tree.
• Never work in unstable locations.

Pull in/recoil

△DANGER

Uncontrolled movements of the chainsaw

Danger of death from incision injuries

Plan the cut before cutting and identify any potential dangers.

Always hold the chain saw firmly with both hands.

Pull in/recoil is an effect that occurs in principle in the opposite direction to the chain running direction on the sawed material.

Illustration P

① Pull in

② Recoil

When sawing with the underside of the guide rail - forehand cut - the chainsaw can be pulled suddenly towards the sawn object if the saw chain jams or hits a solid object in the wood.

• To avoid pulling in, always set the bucking spikes securely onto the wood.

When sawing with the top side of the guide rail (backhand cut), the chainsaw can be propelled back towards the user if the saw chain jams or hits a solid object in the wood.

• To avoid a recoil:
• Do not pinch the top of the guide rail.
• Do not twist the guide rail in the cut.

Kickback

△DANGER

Uncontrolled movements of the chainsaw

Danger of death from incision injuries

Plan the cut before cutting and identify any potential dangers.

Always hold the chainsaw firmly with both hands.

When kickback occurs, the chainsaw is suddenly and uncontrollably flung in the direction of the user.

A kickback occurs when, e.g., the saw chain in the upper region of the blade guide tip unintentionally encounters an obstacle or is trapped.

Illustration Q

Always hold the chainsaw so that the kickback forces can be withstood. Do not let go of the chainsaw. Do not bend too far forward when sawing. Do not use the chainsaw above shoulder level. Always wait until the chain has reached full speed and saw at full throttle. Do not saw with the saw rail tip. Insert the guide rail into a started cut only with extreme care. Pay attention to the position of the trunk and to forces that can close the cut and jam the saw chain. Never saw off several branches at the same time when pruning. Only work with a sharp and properly tensioned chain. Use a chain with a low kickback risk and a guide rail with a small rail head.

Plan the fall direction and retreat path

DANGER

Falling tree

Danger of death

Tree felling work may only be carried out by trained persons.

When planning the fall direction, note the following:

The distance to the next workplace must be at least 2.5 tree lengths. Do not perform felling in strong wind. The tree can fall unchecked. Determine the direction of fall based on tree growth, terrain (slope) and weather conditions. Always drop the tree into a growth gap, never onto other trees.

A retreat path must be planned for every worker. Where:

The retreat path is to be positioned approx. 45° diagonally opposite the direction of fall.

Illustration R

Free the retreat path from obstacles. Do not place any tools and equipment on the retreat path. When working on a steep slope, plan the retreat path parallel to the slope. When using the retreat path, watch for falling branches and observe the crown space.

Preparing the work area at the trunk

1. Clean the work area at the trunk of interfering branches, scrub and obstacles. Safe stance ensured.
2. Thoroughly clean the root, e.g. with an axe. Sand, stones and other foreign matter make the chain blunt.
3. Remove large roots.

a Cut the root vertically.

Illustration S

b Cut the root horizontally. c Remove the loose root piece from the work area.

Setting the felling cut

△DANGER

Falling tree

Danger of death

Tree felling work may only be carried out by trained persons.

1. Make sure nobody will be endangered by the falling tree. Calls can be overhead due to engine noise. Only persons occupied with felling may be present in the felling area.
2. Set the felling notch at right angles to the direction of fall.

a As close as possible to the ground, make a horizontal cut (sole cut) over approx. 1/3 of the trunk diameter.

Illustration T

b Make an oblique cut (roof cut) at an angle of approx. 45-60°.

1. Set the felling cut.

a Make the felling cut parallel to the sole cut and at least 50 mm higher. b Only make the felling cut so far that a break-off strip at least 50 mm wide remains. The break-off strip prevents the tree from twisting and falling in the wrong direction. As the fell line approaches the break-off strip, the tree should begin to fall. 4. Stop the felling cut if there is a danger that the tree will not fall in the desired direction or sway back and jam the saw chain. Use wedges to extend the cut and fell the tree in the desired direction. 5. Pull the chainsaw out of the cut when the tree starts to fall. 6. Switch off the device. 7. Lock the chain brake. 8. Lower the chainsaw. 9. Follow the planned retreat route.

maintained cutting

tools with sharp cutting edges are less likely to bind and are easier to control.

Power tools, accessories, working tools, etc. must be used in accordance with these instructions. In doing so, it is necessary to take into account the working conditions and the type of work to be performed. Using power tools for purposes other than those intended may lead to dangerous situations.

Use and maintenance of battery blocks. Charge battery blocks only with the chargers supplied by the manufacturer. Chargers that are not suitable for the corresponding battery block can lead to a fire.

Use the device only with the appropriate

battery. Using other battery blocks can lead to injury and the risk of fire.

Do not store unused battery packs near paper clips, coins, keys, nails, screws, or other small metal objects that can cause a short circuit. A short circuit can lead to fire or explosion.

Under certain conditions, liquid may leak from the battery. Avoid contact with it. If contact with liquid occurs, rinse thoroughly with water. If liquid gets into the eyes, consult a doctor. The electrolyte may cause skin irritation and burns.

6. Servicing of the power tool must be performed

only by qualified specialists and only using original spare parts. This ensures the safety of the tool.

Safety precautions listed below:

• Hold the saw with both hands, gripping the handles with all fingers. The body of the saw must be in a position that allows you to maintain balance during operation. Take appropriate measures to be able to handle the saw. Never let go of the saw.
• Avoid unnatural body positions during work and do not work above shoulder level. This will help prevent accidental contact with the guide rail and better control the saw in unexpected situations. Use only the guide rails and saw chains specified by the manufacturer. Using incorrect guide rails and saw chains may lead to chain breakage and/or kickback. Sharpening and maintenance of the saw

chain must be carried out according to the manufacturer's instructions. Too low positioned cutting guards increase the risk of kickback.

Working position

DANGER

Uncontrolled movements of the saw chain

Danger of injury

Before starting to cut, plan the cuts and assess the dangers.

Always hold the saw chain firmly with both hands.

Do not work with the saw chain in the same plane as the body.

Position the saw body to the side so that no part of your body is in the path of the blade. Keep as far away as possible from the material being cut. Never work from a ladder or on a tree. Never work from an unstable position.

Kickback

DANGER

Uncontrolled movements of the saw blade

Danger of injury from kickback

Before starting to cut, plan the cut and be aware of the dangers.

Always hold the saw firmly with both hands.

Kickback effects can occur suddenly in the direction opposite to the movement of the blade in the material being cut.

Figure R

① KICKBACK

② SAW

If during cutting with the lower side of the blade (plunge cut) the saw gets stuck or hits a hard object in the wood, the saw may be suddenly thrown back in the direction of the material being cut.

• To prevent kickback, always securely fix the workpiece.

If during cutting with the upper side of the blade (reverse cut) the saw gets stuck or hits a hard object in the wood, the saw may be suddenly thrown back in the direction of the operator.

Do not grip the upper side of the blade. Do not twist the blade in the cut.

KICKBACK

DANGER

Uncontrolled movements of the saw blade can cause injury.

Before starting to cut, secure the workpiece and eliminate hazards.

Always hold the saw blade firmly with both hands.

In case of kickback, the saw blade can be thrown suddenly and uncontrollably towards the operator.

Kickback occurs, for example, when the saw blade accidentally hits an obstacle or gets pinched in the upper part of the saw cut.

Figure Q

Always hold the saw blade in such a way that you can counteract the forces of kickback. Do not let go of the saw blade. During cutting, do not lean too far forward. Do not raise the saw blade above shoulder height. Always wait until the blade has reached full speed before cutting at full revolutions. Do not use the saw blade with a dull chain. Insert the blade into the cut carefully. - Pay attention to the position of the bar and the chain, which can get caught or pinch the saw blade. - When cutting branches, never cut several branches at once. Work only with a sharp and properly tensioned saw chain. - Use a chain with low kickback risk and a blade with a small tip.

Planning the fall and escape path

DANGER

Felling a tree

Danger to life

When planning the felling direction, the following must be taken into account:

The distance to the nearest work site must be at least 2.5 times the height of the tree. Do not fell trees in strong wind. The tree may fall uncontrollably - determine the direction of fall based on the shape of the tree, the terrain (slope) and weather conditions. Fell the tree only in the gap between trees. Never fell a tree onto other trees.

Each worker must have a planned escape route. Considerations are as follows:

• The escape route should be at an angle of approximately 45 degrees in the direction opposite to the felling direction.

Figure R

Clear the escape route of obstacles. Do not leave tools or equipment on the escape route. When working on a steep slope, plan the escape route parallel to the slope. When retreating, watch for falling branches and remember the size of the crown.

Preparation of the work area around the trunk

1. Clear the work area around the trunk of branches, undergrowth and obstacles that will hinder the work. Ensure a stable position.
2. Carefully clear the trunk base and the felling notch with an axe.

Sand, stones and other foreign materials will dull the chain.

3. Cut the lateral roots.

a Cut the root vertically.

Figure S

b Cut the root horizontally. c Remove the cut root from the work area.

Making the main cut

DANGER

Felling tree

Danger to life

Felling of trees may only be carried out by trained personnel.

1. Make sure that the falling tree does not endanger anyone. Calls may not be heard due to engine noise.

Only persons involved in the felling may be in the felling zone.

1. Make the cuts at right angles to the felling direction.

As close to the ground as possible, make the horizontal cut (lower cut) at about 1/3 of the trunk diameter.

Figure T

Make the oblique cut (upper cut) at an angle of approx. 45-60°.

1. Make the main cut.

Make the main cut parallel to the lower cut, at least 50 mm above. Make the main cut only to such a depth that at least 50 mm of hinge remains.

The hinge does not allow the tree to twist and fall in the wrong direction.

When the main cut approaches the hinge, the tree should begin to fall.

1. This creates a risk that the tree will fall in the wrong direction or lean back, pinching the saw chain in the cut. Using wedges, widen the cut and fell the tree in the desired direction.
2. When the tree starts to fall, pull the saw chain out of the cut.
3. Turn off the device.
4. Engage the chain brake.
5. Lower the saw. 9. With a planned path.

Cutting tensioned wood

DANGER

Uncontrolled movements of the saw chain when cutting material

Dangerous cuts and injuries from the material being cut

Before starting to cut, plan the cuts and assess the dangers.

Always hold the saw firmly with both hands.

Tensioned wood can spring back when the trunk, branches, roots, or parts of another tree are under mechanical stress.

1. Watch out for tensioned wood, as there is a risk of it suddenly releasing.

Cutting branches

DANGER

Risk of kickback

Dangerous cuts that can be life-threatening

When cutting branches, make sure that the chain and the bar do not get caught.

WARNING

Change in weight distribution when cutting branches

Risk of injury due to uncontrolled movement of the saw

Choose the work area in such a way as to eliminate danger.

• Cut branches in the direction of growth. Figure W
• Cut branches from the bottom up. Leave larger branches at the bottom as support, which will hold the trunk above the ground. Secure the saw as best as possible. Do not work standing on the trunk. Move the tip of the bar. Watch out for tensioned branches. Cut tensioned branches from the bottom up. Never cut several branches at the same time.
• Regularly clean the work area of cut branches.

professional users).

The cable must not be used for other purposes, e.g., for carrying or hanging the power tool.

Keep the cable away from heat, oil, sharp edges or moving parts. Damaged or entangled cables increase the risk of electric shock.

When working outdoors with a power tool, use only extension cords suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

If operating the power tool in a damp environment cannot be avoided, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

Safety of people: be attentive and watch what you are doing; approach work with the power tool sensibly. Do not

Do not use the power tool if you are under the influence of drugs, alcohol, or medication. A moment of inattention while operating the power tool may result in serious personal injury.

Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking 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.

Remove any adjusting key or wrench before 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 better control of the power tool in unexpected situations.

Dress properly. Do not wear loose clothing 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 dust collection can reduce dust-related hazards.

4 Power tool use and care

Do not force the power tool. Use the correct 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 adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

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

Maintain power tools. Check for misalignment or binding of moving parts, breakage 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. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

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 different from those intended could result in a hazardous situation.

When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection 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 from the battery may cause irritation or burns.

6 Service

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.

Risk reduction

• Longer operating time of the device may lead to damage. Damage to the surface of the workpiece, vibrations. The actual operating time cannot be set in advance; it depends on many factors that have an influence:
• People with problems with blood circulation (e.g., poor blood circulation in the hands, tingling in the fingers) should not use this device. Low ambient temperature. Wear gloves to protect the hands. Impaired blood circulation leads to unhealthy gripping.
• Continuous work is more harmful than work interrupted by breaks. If the device is used regularly and correctly, and if symptoms such as tingling and numbness in the fingers occur, you should consult a doctor.

Intended use

DANGER

Use other than intended use

Danger to the user from cuts and injuries if the device is not used as intended.

The vertical drill is intended only for use in private households. The vertical drill is intended only for outdoor work. The safety equipment of the vertical drill must be kept in good condition with both hands. The vertical drill is designed for drilling into wood, wood-like materials, and plastics. The cutting depth is determined by the maximum possible diameter of the material to be drilled. The vertical drill must be used only for drilling into wood material. Do not use the vertical drill in damp or wet environments or in the rain. - Use the vertical drill only in well-lit environments. The safety equipment and protective devices supplied by the manufacturer must be used.

Safety devices

CAUTION

Safety devices are provided for your protection.

Never bypass or disregard safety devices.

Belt with low risk of kickback

The belt with low risk of kickback reduces the risk of kickback.

The teeth of the saw (guide bar) must be sharpened before each use to prevent the saw teeth from being pulled into the kickback zone, thus reducing the risk of kickback. The saw chain must be replaced if the protective function is deactivated. If the chain is damaged, the saw must be replaced according to the safety instructions. For this, use only the recommended manufacturer's spare parts.

The teeth on the ratchet (locking pawl) must be placed against all teeth of the ratchet to prevent the ratchet teeth from engaging at the point of the catch, thus following the catch. The adjustment of the ratchet may pose a risk that this protective function could be deactivated. If the power of the ratchet is reduced, the ratchet must be replaced according to the safety regulations. For this, for the spare parts, use only the manufacturer's recommended parts. The company sends the ratchet and the ratchet.

When adjusting the guide rail, note that the upper end of the rail may be released due to the risk of tipping.

Then use the guide rail for work with a chain that is sufficiently long. Longer guide rails increase

the probability of losing control during cutting.

Before starting operation, check the chain tension (see chapter Checking the chain tension). If the chain tension is not set correctly, during cutting with a smaller chain (thinner than the guide rail's groove) there is a higher risk of the chain coming off.

Chain brake

If the chain comes off or breaks, the chain brake prevents the chain from being thrown at high speed towards the operator.

Limited cut

The built-in limited cut can be used as a tip stop to provide stability to the upper handle during cutting.

When cutting, press the handles until the metal parts enter the first cut. When the saw chain is then lifted up, respectively down in the direction of the cut, the load on the upper handle is reduced.

Chain catcher

The chain catchers are designed to quickly catch the chain in case of danger. If the chain catcher is pressed in the direction of the guide rail, the chain must stop immediately. The chain catcher cannot prevent a kickback, but it can reduce the risk of injury if the chain or guide rail hits the operator. Before each start-up in operation, the chain catcher must be checked for proper functioning (see chapter Checking the function of the chain catcher).

ONACHOCT

WARNING: Risk of injury from kickback. Before cutting, inspect the saw and identify the hazards.

Hold the upper saw handle firmly with both hands.

During kickback, the saw is thrown back suddenly and uncontrollably toward the user.

Kickback occurs when the saw chain in the upper zone of the guide bar hits an obstacle or becomes pinched.

Figure Q

Hold the upper saw handle so that you can control the kickback. Do not let go of the upper handle. - Do not lean too far forward. Do not guide the upper handle above shoulder height. Hold the saw firmly until the chain reaches full speed before cutting with full force. Do not cut with the tip of the guide bar. Engage the guide bar only with extreme caution at the end of the cut. Watch the bar and be alert for forces that may close the cut and pinch the chain. - Never cut several branches at once. Work only with a sharp and properly tensioned chain. - Use a chain with a lower risk of kickback and a guide bar with a small tip.

Planning the felling direction and escape route

DANGER

Felling a tree

Danger to life

Felling work must only be carried out by trained personnel.

When planning the felling direction, observe the following:

The distance to the nearest work area must be at least 2.5 tree lengths. Do not perform felling work in strong wind. The tree may fall uncontrollably. - Determine the felling direction using the tree's lean, terrain characteristics (slope), and weather conditions. Position the tree to fall where there is vegetation, never onto other trees.

For every worker, an escape route must be planned. Important here:

Escape route at an angle of 45° to the felling direction.

Figure R

Clear the cutting area of obstacles. Do not leave any tools or debris in the cutting area. - When working on steep slopes, plan the cutting direction to accelerate the slope. When using the cutting attachment, follow the instructions for the blade guard zone.

Preparing the work area of the blade

1. Clean the work area of the blade from branches, twigs, and obstacles.

Assume a stable position.

2. Clean the base of the blade thoroughly, e.g., with a brush.

Rocks, stones, and other hard objects can damage the blade.

1. Remove any root growth.

a. Cut the root growth vertically. Figure 5

b. Cut the root growth horizontally. c. Remove the freed part from the root from the work area.

DANGER

Kickback

Danger of cutting injuries when cutting

When cutting, be careful that the guide bar and chain do not get caught.

Procedure for distributing the load when cutting

Danger from uncontrolled movement of the trunk

Keep the work area clear so that no danger arises.

• Cut in the direction of the fall. Figure aW
• Make the first cut. Leave a larger hinge as a support, so that the trunk stays on the ground.
• If possible, secure the top of the trunk. Do not cut while standing on the trunk. Do not cut with the tip of the saw. Be careful of branches under tension. Cut branches under tension from the bottom up. Never cut a branch that is overhead.
• Regularly clear the work area of cut branches.

Cutting the trunk to a specific length

DANGER

Uncontrolled movement of the saw chain is a danger to the operator due to cutting injuries. Plan the cuts in advance and identify the dangers.

Hold the saw firmly with both hands and with a firm grip.

WARNING

Measure the distance when the tip is in contact with the ground. Follow the measurement to not touch the ground.

1. Place the upper tripod on the limiting plate. 2. Cut evenly through the barrel.

Barrel retraction under tension to a defined length

DANGER

Uncontrolled movement of the upper part is dangerous for the operator and can cause injury when retracting to a defined length under tension. Always follow the sequence of the cut for release from the pressure side and the separating cut from the bending side.

General instructions

Foreword

Use of the manual

Before using the device, read the safety instructions, the original operating instructions, the safety instructions supplied with the battery block, as well as the original operating instructions for the battery block and the standard charger. Follow them. Keep the documents for

future use or for the next owner. Along with the instructions in this operating manual, take into account the general legal regulations and accident prevention regulations.

Safety instructions

Avoid accidents by taking the appropriate precautions listed below:

Hold the power tool by the insulated gripping surfaces, as the cutting tool may contact hidden wiring. The housing and handle must be in a position that allows you to maintain balance during operation. Take appropriate precautions when working in wet conditions. In any case, do not release the trigger.

• Avoid unnatural body posture while working. Do not work above shoulder height. This allows you to avoid accidental triggering of the saw and better control the power tool in unexpected situations.

Use only spare parts and accessories approved by the manufacturer. Using incorrect spare parts and accessories may cause the accessory to break or be ejected.

The technical maintenance of the saw chain must be carried out in accordance with

the manufacturer's instructions.

Sharp, properly tensioned saw chains reduce the risk of kickback.

The cutting depth determines the maximum possible cutting depth of the material.

• Use the pressure washer only for cutting wood. Do not use the pressure washer in wet conditions or in the presence of flammable liquids. Use the pressure washer only in well-lit conditions.
• Unauthorized modifications and changes to the device are not permitted for safety reasons.

Any other use is prohibited. The user is liable for risks arising from improper use.

Environmental protection

Packaging materials are recyclable. Please dispose of packaging in an environmentally friendly manner.

Electrical and electronic devices contain valuable materials that are recyclable and components such as batteries, accumulators, or oil, which if

improperly disposed of or

incorrectly recycled can pose a risk to human health and the environment. However, these components are necessary for the reliable operation of the device. Devices marked with this symbol must not be disposed of with household waste.

Information on components (REACH)

Current information on components is available at: www.kaercher.com/REACH

Trigger gun

If the trigger gun is weak or leaking, replace it immediately to prevent unintentional activation.

Nozzle

The built-in nozzle can be used as a quick-connect nozzle for the pressure washer.

When cutting, guide the device forward until the blade reaches the wood. To move the blade up or down in the cutting direction, operating the pressure washer will be easier.

High risk, for example, when the ladder is unintentionally directed at the switchboard or the upper zones of the wedge.

Keep the ladder at the correct angle so that it can be easily climbed. Do not release the ladder. - When cutting, do not lean too far forward. Do not raise the ladder above the line of the shoulder. Ensure that the ladder has the correct inclination, and work on full steps. Do not work with the wedge. - Install the ladder in the opening of the protective cover. Pay attention to the position of the column on the back, which can bend and press the ladder. - When cutting, never cut several blades at once. - Work only with a sharp and properly tensioned ladder. Use a ladder with a low risk of slipping and with a small wedge.

Creating the main support

SAFETY

Falling tree

Tree safety

Felling trees may only be carried out by trained personnel.

1. Make sure that the tree does not endanger anyone. The branches may fall through the wedge.

The upper wedges may only be located in the wedge.

1. Make a cut at a right angle to the direction of the fall.

Tilt to the ground, make a horizontal cut (lower cut) approximately 1/3 of the diameter of the trunk.

Make a basic cut (top and bottom) at an angle of 45-60°.

1. Make the basic cut.

a) Make the basic cut parallel to the required cut, at least 50 mm above it. b) Make the basic cut only to the depth, leaving at least 50 mm of uncut wood. This prevents the tree from falling in the wrong direction.

When the basic cut approaches the uncut wood, the tree should begin to fall.

4. If there is a risk that the tree will fall in the wrong direction or lean back and pinch the saw chain, stop cutting the basic cut. Use wedges to widen the cut and guide the tree in the desired direction. 5. When the tree starts to fall, remove the saw chain from the cut. 6. Turn off the saw. 7. Remove the wedges. 8. Lower the bar. 9. Proceed with the planned cut.

Cutting felled trees

DANGER

Uncontrolled movement of the saw chain and scattered material

Dangerous kickback of the saw due to scattered material

Before cutting, clear the area and ensure safety.

Always hold the saw firmly with both hands.

Felled trees can spring back when the trunk, branches, roots, or other parts of the tree are under tension.

1. Follow the tension of the tree, as there is a risk of sudden release.

Illustrations

1. Carefully cut the tensioned tree from the compressed side (see also the chapter on cutting trunks under mechanical tension).

• To prevent the power cord from being pulled out, do not use the device if the cord is damaged.

CAUTION

• Do not use the device if the power cord is damaged.

ELECTRIC SHOCK HAZARD

- Read all safety instructions and warnings. Keep these instructions for future reference.

Do not immerse the device in water or other liquids.

Keep all safety instructions and warnings for future reference.

The term "electric shock" used in the safety instructions refers to electric shock from the mains (with voltage) and from battery-operated devices (without voltage).

1. Electrical safety

a) The plug must be clean and dry. Do not use the device in wet or damp areas.

b) Do not use the device in areas where there are flammable gases, vapors, or dust. The device may produce sparks that could ignite these substances.

c) When using the device, keep children and other people away. Do not leave the device unattended.

The device may be damaged if not handled properly.

The electrical plug must be connected to a socket. The plug must not be modified in any way. Do not touch the electrical plug with wet hands together with the electrical cord. Do not reduce the safety distance to water sources of electrical appliances.

Do not allow wet walls, floors, ladders and supports to come into contact with grounded parts. If the floor is wet, the safety distance to water sources of electrical appliances increases.

Protect electrical cords from kinking or twisting. Do not immerse the electrical cord in water, as this reduces the safety distance to water sources of electrical appliances.

To disconnect the electrical cord, do not pull on it; unplug it or

pull it out of the socket. Do not place the cord near heat sources, open flames, or sharp objects. Damaged or tangled cords reduce the safety distance to water sources of electrical appliances.

When working with electrical equipment in an open area, use only extension cords approved for outdoor use. Outdoor extension cords reduce the safety distance to water sources of electrical appliances.

If the electrical cord cannot be disconnected, disconnect the circuit breaker. Circuit breakers reduce the safety distance to water sources of electrical appliances.
