3 SAFETY INSTRUCTIONS

3.1 General electrical machine safety warnings

WARNING! Read all safety warnings, instructions, illustrations and specifications provided with this machine. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

■ Save all warnings and instructions for future reference.

The term "machine" in the warnings refers to your mains-operated (corded) machine or battery-operated (cordless) machine.

3.1.1 Work area safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate machines in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Machines create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a machine. Distractions can cause you to lose control.

3.1.2 Electrical safety

■ Machine plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) machines. Unmodified plugs and matching outlets will reduce risk of electric shock.
- 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.
- Do not expose machines to rain or wet conditions. Water entering a machine will increase the risk of electric shock.
- Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the machine. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
■ When operating a machine 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 machine in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3.1.3 Personal safety

■ Stay alert, watch what you are doing and use common sense when operating a machine. Do not use a machine while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating machines 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 machine. Carrying machines with your finger on the switch or energising machines that have the switch on invites accidents.
■ Remove any adjusting key or wrench before turning the machine on. A wrench or a key left attached to a rotating part of the machine may result in personal injury.
- Do not overreach. Keep proper footing and balance at all times. This enables better control of the machine in unexpected situations.
■ Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing 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.
Do not let familiarity gained from frequent use of machines allow you to become complacent and ignore machine safety principles. A careless action can cause severe injury within a fraction of a second.

3.1.4 Electrical machine use and care

• Do not force the machine. Use the correct machine for your application. The correct machine will do the job better and safer at the rate for which it was designed.
• Do not use the machine if the switch does not turn it on and off. Any machine that cannot be controlled with the switch is dangerous and must be repaired.
  ■ Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the machine before making any adjustments, changing accessories, or storing machines. Such preventive safety measures reduce the risk of starting the machine accidentally.
  ■ Store idle machines out of the reach of children and do not allow persons unfamiliar with the machine or these instructions to operate the machine. Machines are dangerous in the hands of untrained users.
• Maintain machines and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the machine's operation. If damaged, have the machine repaired before use. Many accidents are caused by poorly maintained machines.
• 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 machine, 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 machine for operations different from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the machine in unexpected situations.

3.1.5 Battery machine use and care

■ Recharge only with the charger 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.

■ Use machines 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, 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.
- Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
Do not expose a battery pack to fire or excessive temperature. Exposure to fire or temperature above 130°C may cause explosion.
■ Follow all charging instructions and do not charge the battery pack or machine outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

3.1.6 Service

■ Have your machine serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the machine is maintained.
■ Never service damaged battery packs.

Service of battery packs should only be performed by the manufacturer or authorized service providers.

3.2 Safety instructions for chain saws

General 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 chain saw by insulated gripping surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a "live" wire may make exposed metal parts of the chain saw "live" and could give the operator an electric shock.
■ Wear eye protection. Further protective equipment for hearing, head, hands, legs and feet is recommended. Adequate protective equipment will reduce personal injury from flying debris or accidental contact with the saw chain.
- Do not operate a chain saw in a tree, on a ladder, from a rooftop, or any unstable support. Operation of a chain saw in this manner could result in serious personal injury.
■ Always keep proper footing and operate the chain saw only when standing on fixed, secure and level surface. Slippery or unstable surfaces 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 the bar and chain. Improperly tensioned or lubricated chain may either break or increase the chance for kickback.
- Cut wood only. Do not use chain saw for purposes not intended. For example: do not use chain saw for cutting metal, plastic, masonry or non-wood building materi-

als. Use of the chain saw for operations different than intended could result in a hazardous situation.

Do not attempt to fell a tree until you have an understanding of the risks and how to avoid them. Serious injury could occur to the operator or bystanders while felling a tree.
■ Follow all instructions when clearing jammed material, storing or servicing the chain saw. Make sure the switch is off and the battery pack is removed. Unexpected actuation of the chain saw while clearing jammed material or servicing may result in serious personal injury.

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 chain saw 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.
  ■ Only use replacement guide bars and saw chains specified by the manufacturer. In-correct replacement guide bars and saw 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.

3.3 Safety notes for rechargeable battery and charger

Please observe the safety instructions for the battery and charger in the separate operating instructions:

Batteries: Doc. No. 441630, 443549
■ Chargers: Doc. No. 441633, 443551

3.4 Safety instructions for work

■ Heed the country-specific safety regulations, e.g. from the relevant trade associations, social security systems, authorities for industrial safety.
■ Only work in sufficient daylight or artificial lighting.
- Keep the working area free from objects (e.g. off-cuts) – danger of stumbling.
■ The user is responsible for accidents involving other people and their property.
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.

3.4.1 Operator

■ Young people under 16 years of age and people who do not know the operating instructions are not allowed to use the tool.
To operate the chain saw, you must be rest-ed and in good physical and mental health. If you must not exert yourself for health reasons, ask your doctor whether it is possible to work with a chain saw.

3.4.2 Operating times

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

3.4.3 Vibration load

■ Danger due to vibration

The actual magnitude of the vibration emissions during the use of the appliance may deviate from that stated by the manufacturer.

Observe the following influencing factors before or during use:

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

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

The noise and vibrations of the tool may increase due to improper use and maintenance. This leads to health damage. In this case, immediately switch off the tool and have it repaired by an authorised service workshop.

The degree of stress due to vibration depends on the work to be performed or on the use of the tool. Estimate the stress and plan appropriate work breaks. This considerably reduces stress due to vibration over the entire working time.

- Extensive use of the tool exposes the operator to vibrations, which can lead to circulatory issues ("white fingers"). To avoid this risk, wear gloves and keep your hands warm. If any symptoms of "white fingers" occur, immediately consult a physician. These symptoms include: Numbness, loss of feeling, tingling, itching, pain, reduced muscular strength, changes in the colour or condition of the skin. Normally these conditions affect the fingers, hands or pulse. The risk increases at low temperatures.

Take long breaks during your working day so you can recover from the noise and the vibrations. Plan your work in such a way that the use of appliances that generate strong vibrations is spread over several days.

If you notice an unpleasant sensation or discolouration of the skin on your hands when using the tool, stop work immediately. Take sufficient work breaks. Without sufficient breaks, a hand/arm vibration syndrome can occur.

• Minimise your risk of being exposed to vibrations. Maintain the tool according to the instructions in the operating instructions.
  If the tool is used frequently, contact your dealer to purchase anti-vibration accessories (e.g. handles).
• Avoid working with the tool at temperatures below 10 °C. Define how the vibration load can be limited in a work plan.

3.4.4 Noise pollution

A certain level of noise exposure from this appliance is inevitable. Carry out noisy work at approved and specified time periods. Observe rest periods as necessary and restrict the duration of the work to a minimum. For your personal protection and protection of persons in the vicinity, appropriate hearing protection must be worn.

3.4.5 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 components. 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, remove the rechargeable battery during:

■ Inspection, adjusting and cleaning work
■ Work on the cutting equipment
■ Leaving the chain saw
Transport
Storage
■ Maintenance and repair work
Danger

■ Never work alone.

■ Always keep a first-aid kit to hand in case of accidents.

- Avoid touching metal objects in the ground or which are conductively connected to the ground.

■ The personal protective equipment comprises:

• Protective helmet
  ■ Hearing protection (e.g. ear defenders, especially when working for than 2.5 hours a day)
  ■ Protective glasses or face visor of the protective helmet
  ■ Protective trousers with cut protection in-lay
  Sturdy working gloves
  ■ Safety boots with high-grip sole and steel toe caps

- Do not use the chain saw above shoulder height as safe handling is no longer possible in this position.

■ When changing position, switch off the motor and fit the chain guard.

- When chain saws are not in use, always fit the chain guard and remove the battery.

■ Switch off the chain saw before putting it down.

- Do not use the chain saw for levering or moving wood.

■ Only specialist personnel are allowed to saw trunks that are thicker than the length of the chain bar.

■ Only start the cut once the saw chain is running; never switch on the saw with the saw chain already in the kerf.

■ Make sure that no saw chain oil gets onto the ground.

- Do not undertake sawing work in the rain, snow or stormy weather.

■ Never disable safety and protective devices.

■ Position the cable between battery and chain saw so that it does not get caught on branches or similar when cutting.

4 INSTALLATION

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 inadequate technical knowledge! Inadequate technical knowledge can result in extremely serious up to fatal injury!

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

DANGER! Danger of fatal injury from splintered wood! Wood chips caught up in the chain can cause extremely serious and even fatal injury!

■ Remove loose chips and wood splinters from the part to be sawn.

7.1 Felling trees (16, 17)

Observe the following points before and during felling operations:

• When felling trees, care must be taken to ensure 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 immediately.
  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 212 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
Height of the tree
■ Branches growing on one side
Level ground or slope
■ Asymmetrical growth, wood damage
■ Wind direction and wind speed
Snow load

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

■ Make sure that there are no obstacles in your predetermined escape route. The escape route should be at an angle of approx. 45^ backwards from the falling direction (16).

The trunk must be free of growth, branches 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. First saw the undercut (17/C) horizontally, then at an angle of at least 45^ from above. This prevents the chain saw becoming trapped when you make the second undercut. The undercut must be as close as possible to the ground and in the required felling direction (17/E). The depth of the undercut should be about 1/4 of the diameter of the trunk.

3. Saw the back cut (17/D) exactly horizontally opposite to the undercut. The back cut must be made 3-5 cm above the horizontal undercut.

4. Saw in the back cut (17/D) sufficiently deep so that a bridge (17/F) of at least 1/10 of the trunk diameter remains between the undercut (17/C) and the back cut (17/D). This bridge prevents the tree from twisting and falling in the wrong direction. The tree should start to fall when the back cut (17/D) approaches the bridge (17/F). Do not saw through the bridge! If the tree falls whilst you are sawing:

Interrupt the back cut if the tree falls 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 direction of the required felling line.
- Immediately pull the chain saw out of 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.

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

Note: Use only wedges made of wood, plastic or aluminium.

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

Only experienced or trained people should make plunge cuts, longitudinal cuts and boring cuts (17).

⚠️ DANGER! Danger of fatal injury from a falling tree! Having no escape route when felling a tree represents a danger of serious and even fatal injury!

- Do not start the felling work until you are sure there is an unobstructed escape route away from the tree to be felled.

⚠️ DANGER! Danger of fatal injury from an uncontrollably falling tree! Uncontrolled falling trees can lead to extremely serious and even fatal injury!

In order to guarantee controlled felling of a tree, leave a bridge between the undercut and the back cut. The length of this bridge should be approx. 1/10 of the trunk diameter.
- Do not carry out any felling work in windy conditions.

7.2 Delimbing (18)

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 sequentially from the tree (18/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 (18/b), but not from below.
■ Pay attention to branches under tension, and saw through these from underneath upwards (18/c) in order to avoid the chain saw becoming trapped.

7.3 Cross-cutting (19 - 22)

Cutting to length means dividing the felled tree into 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 wedges.
- When working on a slope, always stand uphill of the tree trunk as it could roll away (19).
■ 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 pull out 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 uniformly in contact with the ground:

■ Saw through the tree trunk from above (20/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 (21/a), then saw through the remainder from above, down as far as the cut made from underneath (21/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 (22/a), then saw through the remainder from underneath, up as far as the cut made from above (22/b).

⚠️ DANGER! Danger of fatal injury due to kickback! The operator can be fatally injured by kickback of the appliance.

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

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 running. Never switch on the chain saw already in the kerf.
- Do not secure the wood with your foot and do not get another person to hold it.

8 MAINTENANCE AND CARE

WARNING! Danger of cuts and lacerations. Danger of cuts and lacerations 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 rechargeable battery.
■ Always wear protective gloves during maintenance, care and cleaning work.

The chain saw complies with all relevant safety standards. Repairs are only allowed to be performed by qualified specialists, and with the exclusive 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.

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 guide rail.
5. Clean the groove in the rail and the oil inlet bore.

8.2 Sharpening the saw chain (23)

DANGER! Danger of fatal injury due to

kickback! Improperly sharpened saw chain increases the danger of kickback and thus the danger of fatal injury.

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

NOTE Inexperienced chain saw operators

are recommended to have the saw chain sharpened by a specialist at the customer service.

The saw chain must always be well-sharpened for reasons of safety and efficiency.

Sharpening is required when:

■ 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 uniform sharpening of all teeth.

You can sharpen the saw chain yourself using special round files whose diameters are adapted to the specific chain type (see chapter 8.4 "Chain maintenance table", page 47). 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 battery.
2. Release the chain brake.
3. Clamp the chain bar 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 angle according to the tooth profile.

6. Perform just a few strokes of the file and exclusively in the forwards direction, then repeat the working step on all teeth in the same orientation (right or left).

7. Reverse the position of the chain bar in the vice and repeat the working step on the remaining teeth.

8. Check that the limit tooth does not project beyond the checking tool, and file off any projection using a flat file, then round down the profile.

9. After sharpening, clean away all filings and dust, then lubricate the saw chain in an oil bath.

The chain must be replaced if:

■ The length of the teeth is less than 5 mm;
■ Where applicable: The mark on the teeth of the cutting elements is exceeded;
■ The play on the links at the chain rivets is excessive.

8.3 Checking, turning and greasing the chain bar (24, 25)

Checking the chain bar

Regularly check the chain bar for damage. If necessary, remove protruding burrs (24/1), i.e. file off at an angle of 45^ (24/2).

Turning the chain bar

The chain bar must be turned over after each chain sharpening and chain change in order to avoid one-sided wear.

Greasing the chain bar

1. Carefully clean groove in rail (24/3) and oil inlet bores (24/4).
2. Carefully clean lubricating hole (25/1) on both sides.
3. Use a grease gun (25/2) to pump in sufficient grease on both sides until the grease emerges evenly at the tips of the sprocket. Keep turning the sprocket while doing this.

\* Notes:

The vibration emission value given has been measured according to a standardised test method and can be used to compare one power tool with another.
The vibration emission value can also be used for an initial assessment of the exposure (vibration exposure degree).
The vibration emission value may differ from the given value during actual use of the power tool, depending on how the power tool is used.

14 AFTER-SALES/SERVICE

• Try to keep the vibration load as low as possible. Exemplary measures to reduce vibration are the wearing of gloves when using the tool and limitation of the working time. All parts of the operating cycle must be taken into account (e.g. times when the power tool is switched off and those in which it is switched on but runs without load).

Batteries and chargers

All batteries (Bxxx Li) and chargers (Cxxx Li) from the AL-KO 36V system can be used.
