Frequently Asked Questions - CS 4030 AL-KO

How to tension the chain of the CS 4030 chainsaw?

To tension the chain, first remove the battery. Loosen the central lock, then turn the rotating ring clockwise until the chain can be lifted 3 to 4 mm at the center of the guide bar. Retighten the lock. Check that the chain can be driven by hand without sagging on the underside.

What oil to use for the chain?

Use a high-quality biodegradable chain oil. Do not use used oil. The tank has a capacity of 180 ml. Check the level through the sight glass and refill before each use if necessary.

How to start the CS 4030 chainsaw?

Make sure the chain brake is released (pull the hand guard towards the handle). Press and hold the lock-off button, then press the throttle trigger. Release the lock-off button once the engine is running.

How to stop the chainsaw?

Simply release the throttle trigger. The engine stops. In case of emergency, push the hand guard forward to activate the chain brake, which immediately stops the chain and engine.

How to test the chain brake?

Before use, test the chain brake with the engine off: the chain must not be able to be advanced by hand when activated. Then, with the engine on, push the hand guard forward: the chain and engine must stop instantly. If not, do not use the chainsaw and contact customer service.

Which batteries are compatible with the CS 4030?

The chainsaw is designed for AL-KO B150 Li (ref. 113280, 36 V, 4 Ah) and B200 Li (ref. 113524, 36 V, 5 Ah) batteries. The corresponding charger is the C130 Li (ref. 113281). Do not use other batteries.

How to sharpen the cutting chain?

Use a round file with a diameter of 4.0 mm with a file holder. File each tooth from the inside out at the correct angle (30°). After 3-4 sharpenings, have the chain professionally sharpened. Replace the chain if the tooth length is less than 4 mm.

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

First check if the chain brake is not activated (release it). If the problem persists, the chain may be too tight: loosen it via the rotating ring. If nothing changes, contact AL-KO customer service.

How to transport and store the chainsaw?

Before transport, remove the battery and attach the chain guard. Carry it by the handle, guide bar to the rear. For storage (more than 30 days), empty the oil tank, clean and oil the chain and guide bar, and store in a dry place out of reach of children.

What are the essential safety precautions?

Always wear a helmet, safety glasses, hearing protection, gloves and safety shoes. Hold the chainsaw with both hands (right hand on rear handle, left on front handle). Never work alone, and keep a first aid kit nearby.

3 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 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.

3.2 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.

3.3 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.

3.4 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.

3.5 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.

3.6 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.

4 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 recommend-

ed. 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.

5 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.

6 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 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).
- Avoid working with the tool at temperatures below 10 °C. Define how the vibration load can be limited in a work plan.

7 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.

Dried/sticky saw chain oil can lead to damage to oil-channeling components and the oil pump. Damage also occurs if used oil is used. The use of used oil leads to environmental damage!

■ For start-up work, fill saw chain oil into the tank.
■ Do not use any used oil!
■ Each time before changing the rechargeable battery at the latest, fill the tank with saw chain oil again.

The saw chain and the chain bar are continuously supplied with oil during operation by means of an automatic oiler system. The saw chain oil protects against corrosion and premature wear.

There must always be sufficient saw chain oil in the tank to lubricate the saw chain sufficiently.

To lubricate the saw chain and the chain bar, only use environmentally friendly, biodegradable, high-quality saw chain oil. This oil must be transported and stored in approved and appropriately labelled containers.

Each time before starting work or changing the rechargeable battery, check the oil level and replenish the saw chain oil if necessary:

1. Check the oil level in the viewing aperture of the tank (09/1). It must always be possible to see oil. The minimum and the maximum oil level must not be exceeded.

2. Refill saw chain oil via the filler neck (09/2) if necessary.

13 OPERATION

⚠️ DANGER! Danger of fatal injury and danger of extremely severe injury. Lack of knowledge of the safety instructions and operating instructions can lead to extremely serious and even fatal injury.

14 WORKING BEHAVIOUR AND WORKING TECHNIQUE

i 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.

14.1 Felling trees

Take the following measures before starting felling work.

■ Make sure that no other people, animals or objects are in the danger area.
■ The safe distance from other workplaces or objects should be at least 212 tree lengths.
- Watch out for power lines and other people's property. If necessary, notify the power supply company or the property owner.

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

Natural lean of the tree
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 (17).
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 (18/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 (18/E). The depth of

the undercut should be about 1/4 of the diameter of the trunk.

1. Cut the back cut (18/D) exactly horizontally opposite to the undercut. The back cut must be made 3-5 cm above the horizontal undercut.
2. Saw in the back cut (18/D) sufficiently deep so that a bridge (18/F) of at least 1/10 the trunk diameter remains between the undercut (18/C) and the back cut (18/D). This bridge prevents the tree from twisting and falling in the wrong direction. The tree should start to fall when the back cut (18/D) approaches the bridge (18/F).

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 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.

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

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

NOTE Only use wedges made from wood, plastic or aluminium.

⚠️ 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.

14.2 Branch lopping

Heed the following points during this work:

■ Support the chain saw against the tree trunk during the work.
In the preliminary phase, leave larger, downward-pointing branches that are supporting the tree (19).
- Cut off smaller branches with one cut.
■ Pay attention to branches under tension, and saw through these from underneath upwards in order to avoid the chain saw becoming trapped (19).
- Do not saw off free-hanging branches from underneath.
■ Only experienced or trained people should make plunge cuts, longitudinal cuts and boring cuts (18).

14.3 Cross-cutting

Heed the following points during this work:

■ When working on a slope, always stand uphill from the tree trunk, because 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.
■ 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 engine 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, without cutting into the ground (20).

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, then saw through the remainder from above, down as far as the cut made from underneath (10).

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, then saw through the

remainder from underneath, up as far as the cut made from above (11).

⚠️ 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.

14.4 Cutting converted timber (12)

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.

15 MAINTENANCE AND CARE

WARNING! Danger of lacerations. Danger of cutting injuries when reaching into sharpedged, 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.

15.1 Sharpening the saw chain (13)

⚠️ 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.

CAUTION! Danger of injury from the saw chain! The sharp edges of the saw chain can cause serious laceration injuries.

■ Wear protective gloves when resharpening the saw chain.

IMPORTANT! Damage to the machine due to incorrect sharpening! Uneven cutting teeth mean that the chain runs roughly and may even break. All cutting teeth must have the same length and width after sharpening.

■ 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.

Do not work with a blunt or damaged saw chain. The consequences include physical strain, a poor cutting result and high levels of chain wear.

To achieve an optimum cutting result, it is necessary for the saw chain to be resharpened at regular intervals.

A correctly sharpened saw chain reduces the danger of kickback and prevents high levels of wear.

Sharpening is required if:

■ The saw chips are like sawdust.
■ Greater force is necessary for cutting.
■ The cut is not straight.
■ Vibration increases.
■ Fuel consumption increases.

To sharpen the chain:

1. Switch off the chain saw and remove the rechargeable battery.
2. Check the chain tension and adjust it if necessary.

3. Only use a suitable tool for sharpening: Round chain file = 4.0 mm, file guide, chain gauge. These tools are available from specialist retailers.

4. The individual chain links consist of a saw link (13/3), saw tooth (13/1) and a depth limiter (13/2).

5. Guide the file from the inside to the outside of the cutting tooth, exerting slight pressure and holding it perpendicular (13). A file guide is helpful for handling the file correctly. 2 – 3 file strokes are sufficient.
6. When sharpening, maintain the angles (13) on the cutting tooth and the height of the depth limiter (13/2) in relation to the cutter. Make sure that all cutting teeth on the chain have equally length and width after sharpening.
7. If using the prescribed tools and the correct handling, the specified angle values will be obtained automatically. The values can be checked with a chain gauge.
8. At the end, slightly round off the front part of the depth limiter (13/2).

Sharpen the saw chain frequently, without removing much material while doing so. After sharpening 3 to 4 times yourself, have the saw chain re-sharpened by a specialist workshop. This also involves resharpening the depth limiter.

Renew the saw chain as soon as the minimum cutting tooth length of 4 mm (13) is reached.

15.2 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. Unscrew the sprocket cover.
3. Clean the inside with a suitable brush.
4. Remove the saw chain and take out the chain bar.
5. Clean the groove in the bar and the oil inlet hole.

15.3 Changing over the quick-tension chain wheel (16)

1. Remove the guide rail (16/1).

2. Unscrew the Phillips screw (16/3) and release the adapter sheet metal from the guide rail with the tensioning hook (16/2).

3. Turn the guide rail around the longitudinal axis.

4. Attach the adapter sheet metal to the chain bar with the tensioning hook again and fix in place with the Phillips screw again.
5. Mount the chain bar again, see chapter 11.1 "Installing the guide rail (05, 06)", page 36.

15.4 Checking, turning and greasing the guide rail (14, 15)

Checking the guide rail

Regularly check the guide rail for damage. Remove any projecting burrs (14).

Turning the guide rail

The chain bar 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 15.3 "Changing over the quick-tension chain wheel (16)", page 42.
2. Turn the guide rail.

Greasing the guide rail

1. Carefully clean groove in bar (14/1) and oil inlet hole (14/2).
2. Carefully clean lubricating hole (15/1) from both sides.
3. Use a suitable grease gun to pump in sufficient grease from both sides in succession until the grease emerges evenly at the tips of the sprocket. Keep turning the sprocket when doing this.
