Frequently Asked Questions - CS 4235 SOLO

How to start the CS 4235 chainsaw?

Ensure the chain brake is disengaged (pull the hand guard towards the handle). Press and hold the lock button (17/1), then press the throttle trigger (17/2). Release the lock button after starting. To stop, release the throttle trigger.

How to properly tension the chain?

Turn the rotating ring (04/1) towards the cover until both triangles face each other. Turn the central lock (05/1) clockwise without fully tightening. Turn the rotating ring (05/2) clockwise until the chain is tensioned: it should be liftable 3 to 4 mm at the center of the guide bar. Then tighten the central lock.

What oil to use for the chain?

Use only biodegradable chain oil of ecological quality. Never use used oil or mineral oil. Fill the tank (250 ml) before each use and check the level through the sight glass.

How to charge the battery?

Connect the battery (127390) to the charger (C150 Li, ref. 127391), then connect the charger to the mains (230 V AC). Charging takes about 150 minutes. The LEDs indicate the charge status. The battery can be charged at any time without risk of overcharging.

What to do if the chain does not turn while the motor is running?

First check the chain tension: if too tight, loosen it. If the problem persists, it may be an internal fault. Contact AL-KO after-sales service.

How to test the chain brake?

Before each use, test the chain brake: with the motor off, push the hand guard forward; the chain must not move. With the motor on, push the hand guard forward; the chain and motor must stop immediately. If not, do not use the chainsaw and have it repaired.

What protective equipment is recommended?

Always wear a safety helmet, hearing protection, safety glasses, sturdy work gloves, cut-resistant protective trousers, and safety shoes with non-slip soles.

How to store the chainsaw for a long period?

Remove the battery, empty the oil tank, clean the chainsaw, remove the chain and guide bar, clean and lightly oil them. Store in a dry, locked place out of reach of children.

What to do in case of kickback?

Hold the chainsaw firmly with both hands, thumbs around the handles. The chain brake activates automatically during a kickback to stop the chain. After the incident, check the chain brake before continuing.

Where to find spare parts and after-sales service?

Contact the nearest AL-KO service center. You can find the contact details on the AL-KO website. Use only original spare parts.

3 SAFETY INSTRUCTIONS

3.1 General Power Tool Safety Warnings

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.

3.1.1 Work area safety

• Keep work area clean and well lit. Cluttered 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 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 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 outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
  If operating a power tools 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 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. Always wear eye protection. Protective equipment such as a 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 energizing 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 bet-

ter 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 these devices can reduce dust-related hazards.

3.1.4 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.

3.1.5 Battery tool use and care

■ Recharge only with the charger specified by the manufacturer. A charter that is suitable 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 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 form the battery may cause irritation or burns.

3.1.6 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.

3.2 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. 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 kick-back.
• 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.

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 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 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.

3.4 Safety information regarding the rechargeable battery

■ 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.

3.6.2 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.

3.6.3 Vibration load

WARNING!

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 can increase due to improper use and maintenance. 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 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 (below approx 10°C).
Take long breaks during your working day so you can recover from the noise and the vibra-

tions. 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 discoloration 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).
■ Define how the vibration load can be limited in a work plan.

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 (19, 20)

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.
■ 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 direction (19).
The trunk must be free from 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. 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 required felling direction (20/E). The depth of the undercut should be about 1/4 of the diameter 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 undercut.

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 direction 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.

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 out for signals or warning calls.

Only experienced or trained people should make plunge cuts, longitudinal cuts and boring cuts (20).

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 (21)

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 (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 becoming trapped.

7.3 Cross-cutting (22 - 25)

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 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.

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 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 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.
■ Only use spare parts specified by the manufacturer.

8.1 Checking the chain tension

Frequently check the chain tension, because new saw chains stretch.

At operating temperature, the saw chain stretches and hangs down.

NOTE

The saw chain has been tensioned correctly 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 customer 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 adapted

to the specific chain type (see chapter 8.6 "Chain maintenance table", page 51). 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 rechargeable battery.
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 angle according to the tooth profile.
6. Only perform 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 guide rail 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 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 excessive.

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.

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

8.4 Changing over the quick-tension chain wheel (27)

1. Remove guide rail (27/1). Remove screw (27/2) and release the adapter sheet metal from the guide rail with the tensioning hook (27/3).
2. Turn the guide rail around the longitudinal axis.
3. Attach the adapter sheet metal to the guide rail with the tensioning hook again and fix in place with the Phillips screw again.
4. Install the guide rail again, see chapter 4.1 "Installing the guide rail (02, 03)", page 43.

8.5 Checking, turning and greasing the guide rail (28, 29)

Checking the guide rail

Regularly check the guide rail for damage. If necessary, remove protruding burrs (28/1), i.e. file off at an angle of 45^ (28/2).

Turning the guide rail

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

1. Change over the quick-tension chain wheel on the guide rail, see chapter 8.4 "Changing over the quick-tension chain wheel (27)", page 51.
2. Turn the guide rail.

Greasing the guide rail

1. Carefully clean groove in rail (28/3) and oil inlet bores (28/4).
2. Carefully clean lubricating hole (29/1) from both sides.
3. Use a grease gun (29/2) to pump in sufficient grease on both sides until the grease emerges evenly at the tips of the sprocket. Keep turning the sprocket when doing this.

Electrical and electronic appliances can be handed in at the following places at no charge:

■ Public service disposal or collection points (e.g. municipal building yards)
■ Points of sale of electrical appliances (stationary and online) provided traders are obliged to take them back or offer this voluntarily.

These statements only apply to appliances that are installed and sold in the countries of the European Union and are subject to European Directive 2012/19/EU. Different provisions may apply to the disposal of electrical and electronic appliances in countries outside the European Union.

Information on the German Battery Act (BattG)

Used batteries and rechargeable batteries do not belong in household waste, but should be collected and disposed of separately.

For safe removal of batteries or rechargeable batteries from the electrical appliance and for information on their type or chemical system, follow the further information within the operating or installation instructions.
- Owners or users of batteries and rechargeable batteries are obliged by law to return them after use. Return is limited to the handover of customary household quantities.

Used batteries can contain harmful substances or heavy metals that can cause damage to the environment and human health. Reuse of the used batteries and use of the resources contained therein contributes to the protection of these two essential commodities.

The symbol of the crossed-through rubbish bin means that batteries and rechargeable batteries may not be disposed of in household rubbish. In addition, if the symbol Hg, Cd or Pb appears under the rubbish bin, this stands for the following:

■ Hg: Battery contains more than 0.0005 % mercury
Cd: Battery contains more than 0.002 % cadmium
■ Pb: Battery contains more than 0.004 % lead Rechargeable batteries and batteries can be handed in at the following places at no charge:
■ Public service disposal or collection points (e.g. municipal building yards)
■ Points of sale of batteries and rechargeable batteries
■ Disposal points of the common take-back system for the used batteries of appliances
■ Disposal point of the manufacturer (if not a member of the common take-back system)

These statements apply only to rechargeable batteries and batteries that are sold in the countries of the European Union and that are subject to European Directive 2006/66/EU. Different provisions can apply to the disposal of rechargeable batteries and batteries in countries outside the European Union.

* 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.
■ 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 the limitation of 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).
