GENERAL SAFETY INSTRUCTIONS FOR POWER TOOLS
WARNING! All safety instructions, user manuals, images and regulations supplied with these tools must be read. Failure to follow all of the following instructions may result in electric shock, fire, and/ or serious personal injury.

• All instructions and the user manual must be kept for future reference.
• The term “power tool” in all the following warnings refers to a mains-powered tool (with a power cord) or a battery-powered tool (without any power cord). This manual applies only to power tools that are powered by a battery without a power cord.

Safety in the working environment

• The workplace must be kept clean and well lit.
  Clutter and dark areas are often the cause of accidents.

• Power tools must not be used in potentially explosive atmospheres where flammable liquids, gases or dust are present. Power tools create sparks that can ignite dust or fumes.

• Children and other persons must be kept away when using power tools. If the operator is distracted, they may lose control of the operation.

Electrical safety

• The operator must not touch grounded objects, such as pipes, central heating units, cookers and refrigerators. The risk of electric shock is greater if your body is connected to the ground.
• Power tools must not be exposed to rain, moisture or wetness. If water enters the power tool, the risk of electric shock increases.
• The tool can generate a weak electromagnetic field that is not dangerous to humans. However, persons with pacemakers or similar devices should contact the manufacturer of the device or consult their doctor for advice.

Safety of persons

• When using a power tool, the operator must be careful, pay attention to what they are doing, concentrate and think clearly. Power tools must not be used if the operator is tired or under the influence of drugs, alcohol or medication. A moment’s inattention while using a power tool can result in serious personal injury.

• Use personal protective equipment. Always use eye protection. Protective equipment such as a respirator, non-slip safety shoes, hard hat and hearing protection, used in accordance with the working conditions, reduces the risk of personal injury.

• Unintentional starting of the machine must be avoided. Make sure that the switch is in the off position before connecting the battery, lifting or carrying the tool. Carrying the tool with your finger on the switch or with the tool switched on can cause accidents.

• All adjusting tools or wrenches must be removed before switching on the tool. An adjusting tool or wrench that remains attached to the rotating part of the power tool may result in personal injury.

• The operator must only work in places that they can safely reach. The operator must always maintain a stable posture and balance. This will allow better control of the power tool in unforeseen situations.

• Dress appropriately. Do not wear loose clothing or jeweler. The operator must make sure that their hair and clothing are a sufficient distance away from moving parts.
  Loose clothing, jeweler and long hair can be caught in moving parts.

• Where equipment is provided for connecting dust extraction and collection facilities, care must be taken to ensure that it is connected and used correctly. The use of such equipment can reduce hazards caused by dust.

• The operator must not allow themselves to become lax and ignore the principles of work safety due to the routine that results from the frequent use of the tool. Careless actions can cause serious injuries in a split second.

Use and maintenance of power tools

• Power tools must not be overloaded. It is essential to use the correct power tool for the work being carried out. The correct power tool will do the work it was designed to do better and safer.
• Power tools that cannot be switched on and off with the switch must not be used. Any power tool that cannot be operated with the switch is dangerous and must be repaired.
• The battery must be removed from the power tool before making any adjustments, changing accessories, or storing power tools. These precautions reduce the risk of accidentally starting the power tool.
• Unused power tools must be stored out of the reach of children. Persons unfamiliar with the power tool or these instructions must not be allowed to use the power tool. Power tools are dangerous in the hands of inexperienced users.
• Power tools and accessories must be maintained. The adjustment and mobility of moving parts must be checked and attention focused on cracks, broken parts and any other circumstances that may compromise the function of the power tool. If the tool is damaged, it must be repaired before use. Many accidents are caused by poorly maintained power tools.
• Cutting tools must be kept sharp and clean. Properly maintained and sharpened cutting tools are less likely to catch on material or jam and are easier to control.
• Power tools, accessories and tool bits etc. must be used in accordance with these instructions and in the manner intended for the particular power tool, taking into account the working conditions and the work to be carried out. Using power tools for activities other than those for which they are designed can lead to dangerous situations.
• Handles and grip surfaces must be kept dry, clean and free of grease. Slippery handles and gripping surfaces mean the tool cannot be held and controlled in unexpected situations.
• Do not use cloth work gloves when using power tools as these can become entangled. Cloth work gloves becoming tangled in moving parts can cause personal injury.

Use and maintenance of cordless tools

• The tool must only be charged with the charger specified by the manufacturer. A charger that may be suitable for one type of battery pack may cause a fire risk when used with another battery pack.
• The tool must only be used with a battery that is specifically designed for the tool. The use of any other batteries may cause a risk of injury or fire.
• When the battery is not in use, it must be protected from contact with other metal objects, such as paper clips, coins, keys, nails, screws, or other small metal objects that can cause one battery contact to come in contact with another. Short-circuiting the battery terminals may cause burns or fire.
• If used incorrectly, liquids may leak from the battery; contact with them should be avoided. In the case of accidental contact with these fluids, the affected area must be rinsed with water. In addition, seek medical attention if fluid gets into the eye. Liquids escaping from the battery can cause inflammation or burns.
• A battery or tool that is damaged or modified must not be used. A damaged or modified battery can exhibit unpredictable behavior, which can result in fire, explosion, or the risk of injury.
• The battery or tool must not be exposed to fire or excessive heat. Exposure to fire or temperatures above 130°C may cause an explosion.
• All charging instructions must be followed, and the battery or tool must not be charged outside the temperature range specified in the operating instructions. Improper charging or charging at temperatures outside this range may damage the battery and increase the risk of fire.

Servicing

• Power tool repairs must be carried out by qualified personnel using identical spare parts. This will ensure the same level of safety of the power tool as before the repair.
• Damaged batteries must never be repaired. Batteries should only be repaired by the manufacturer or an authorized service centre.
• Follow the instructions for deleting and replacing accessories in this manual.

SAFETY INSTRUCTIONS FOR HAND SAWS
WARNING: This hand saw is designed exclusively for tree branching.

• The saw must only be used by trained personnel using a carefully designed safe working system.
• Keep all body parts away from the chain, especially when the saw is in operation. Before starting the saw, make sure that the chain does not touch anyone or anything. A moment’s inattention while handling a running saw can cause clothing or body parts to come in contact with the chain, which can cause serious injury.
• Keep handles dry, clean and free of oil or grease. Greasy or oiled handles can cause the saw to slip so you lose control of it.
• Always hold the saw with both hands. Always hold the saw by the main handle with your right hand and the front handle with your left. Reversed holding increases the risk of injury and the saw should never be held in this way.
• Only hold power tools in insulated places if hidden wiring is cut. If the chain comes into contact with live lines, the metal parts of the saw that are also live may explode and the operator may suffer an electric shock.
• Wear eye and ear protection. We recommend using head, hand, leg and foot protection. Proper protective clothing reduces the risk of injury from flying debris or contact with the chain.
• Use clamps or similar tools to secure the workpiece on a stable surface. Holding the workpiece in your hand or against your body does not provide sufficient stability and can lead to loss of control.
• Make sure you wear suitable work shoes for operating power tools, especially when standing on stairs or ladders. Slippery or unstable surfaces can cause you to lose balance and control of the saw.
• Only move the power tool closer to the workpiece when it is switched on. Otherwise, there is a risk of kickback if the power tool gets stuck in the workpiece.
• Make sure that the guard is placed securely when cutting. A jammed chain may break or cause kickback.
• When you have finished cutting, switch off the power tool, wait until it has come to a complete stop and then remove it from the cut. In this way it prevents kickback and you can store your power tool safely.
• Only use an undamaged chain that is in perfect condition. A bent or blunt chain can break, adversely affect cutting or lead to kickback.
• After switching off, do not brake the saw chain until it stops by pushing on the side. The saw chain can be damaged, broken or kickback.
• Use suitable detectors to determine hidden cabling or contact your local electricity supplier. Contact with cabling may result in fire or electric shock. Damage to a gas pipe can lead to an explosion. Damage to water pipes can cause damage to the property.
• The chain may break under excessive loading. In this case, replace the chain with an original part.

Causes and protection of the operator against kickback:
Kickback can occur when the tip of the guide bar touches a foreign object or when the wood behind the saw contracts and grips the chain in the cut. Tip contact can cause sudden kickback in some situations and can throw the guide bar up and back at the operator. Clamping the chain along the top of the guide bar can quickly push it back towards the operator. Each of these reactions can cause you to lose control of the saw, which can result in serious personal injury. Do not rely solely on the saw’s built-in safety features. As a chainsaw user, you should take a few steps to prevent accidents or injuries while cutting. Kickback is the result of improper use of the tool and/or improper operating procedures or conditions and can be prevented by taking the following appropriate measures:

• Hold the handles firmly so that your thumbs and fingers encircle the chainsaw handles. Keep both hands on the saw. Stand up and stretch your arms to withstand the force of recoil. The recoil force can be controlled by taking the appropriate action. Do not activate the chainsaw.

• Do not overestimate your strength and do not cut at a height above shoulder level. This will help prevent unwanted contact with the guide bar tip and allow better control of the saw in unexpected situations.

• Only use the original replacement guide bar and chain recommended by the manufacturer. Non-original or non-recommended replacement guides and chains can cause damage to the saw and/or kickback.

• Follow the grinding and maintenance instructions for the chainsaw in this manual.

• Decreasing the depth stop height can lead to an increased risk of kickback.

• Before starting the saw, make sure that the chain is in proper operating condition and that its condition complies with safety regulations. Check in particular:
  – that the deceleration brake works correctly;
  – that the guide bar and sprocket cover are correctly fitted;
  – that the chain is sharpened and tensioned in accordance with the regulations.

• Do not switch on the saw if a protective cover is attached to the chain. This may damage the protective cover. Discarded broken parts of the cover can cause personal injury or damage to property.

• Avoid use in hazardous environments. Do not use the saw in humid or wet environments or expose it to rain. If water enters the saw, the risk of electric shock will increase.

• Do not throw the battery into a fire. It can explode. Follow the instructions for ecological disposal.

• Do not open or deform the battery. The electrolyte is corrosive and may damage the eyes or irritate the skin. It is a toxic substance, do not swallow it.

• Do not charge the battery in rain or humid environments.

• When handling the battery, always follow the instructions, directions and warnings in the relevant operating manual.

THE SAFETY AND USER INSTRUCTIONS IN THIS MACHINE MANUAL MUST ALWAYS BE FOLLOWED EVEN IF YOU ARE FAMILIAR WITH THE USE OF THE MACHINE. IMPROPER USE OR FAILURE TO FOLLOW THE SAFETY OR USER INSTRUCTIONS IN THIS MANUAL CAN CAUSE SERIOUS PERSONAL INJURY.

If you need to remove the battery, press the button on the battery and pull it out of the saw.
When inserting and removing the saw, hold the battery firmly to prevent damage from improper handling (e.g., falling).
Do not insert or remove the battery by force. If it cannot be easily removed, it is likely that it has not been inserted correctly. Contact an authorized service centre.
Checking the charge status
The battery is fitted with a charge status indicator (3 LEDs). To check the charge status, press the button on the side (Fig. C).
If all LEDs are lit, the charge level is high. When two LEDs are lit, the battery is partially discharged. If only one LED is lit, the battery is discharged and must be recharged.
PREPARATION FOR USE
Before preparing for use, make sure that the saw is switched off and the battery is removed.
Warning: Do not touch the chain with bare hands. Always wear protective gloves.
Protective cover
The protective cover protects the chain from damage, e.g. during storage, and prevents injuries or hazardous situations. It is important to do so after each use.
Take extra care when inserting or removing the protective cover to avoid injury from the chain. We recommend wearing protective gloves.

1. Lift the cover bar.
2. Attach or remove the protective cover (Fig. C1).
3. Carefully fold down the cover strip (Fig. C2).

Removing the chain
Warning: Take extra care when removing the chain after use, as both the chain and the guide bar may be hot. They become hot during operation. This is a normal occurrence. In this case, let the saw cool down.

1. Press the edge of the lock to release the chain and pull out the lever that is part of the lock (Fig. D1).
2. Turn the lock counterclockwise until the sprocket cover is released (Fig. D2).
3. Carefully remove the sprocket cover.
4. Carefully remove the chain from the sprocket first and then from the guide bar. Then remove the guide bar from the saw body (Fig. D3 – 1. Sprocket cover; 2. Saw body; 3. Chain; 4. Guide rail).

Attaching the chain

1. Before attaching the chain, make sure that it is fitted in the correct direction. There is a mark on the chain that shows the direction (Fig. E1).
2. First, place one part of the chain on the guide bar (Fig. E2)
3. Then place the guide bar against the saw body and place the other part of the chain on the sprocket (Fig. E3).
4. Finally, attach the guide bar to the saw body.
5. Replacing the sprocket cover. Make sure that the tabs on the inside of the cover fit into the holes in the saw body (Fig. E4).
6. Turn the lock clockwise to secure the cover (Fig. E5). Then return the lever to its original position (Fig. E6).

Adjusting the chain tension
Warning: Adjust the chain tension in a clean environment. Avoid dusty or polluted environments.
Do not overtighten the chain. Excessive tension can cause the chain to break and damage the guide bar and saw.
Warning: A loose chain can fall off the guide bar and cause serious injury. Always make sure that the chain is correctly fitted and not overtightened or stretched.
The chain may come loose during use, so it is important to check regularly check the tension.

1. Press the edge of the lock to release the chain and pull out the lever that is part of the lock (Fig. F1).
2. Turn the lock counterclockwise and slightly release the sprocket cover.
3. The chain head screw is used to adjust the chain tension. Tighten the chain by turning the screw clockwise; loosen the chain by turning the screw counterclockwise (fig. F2).
4. To check that the chain is correctly tensioned, pull it with 1 kg of force. If the distance between the inside of the chain and the guide bar is 3 to 4 mm, the chain is correctly  tensioned (Fig. F3). If the distance is less than 3 mm, the chain is too tight and needs to be released. If the distance is greater than 4 mm, the chain is loose and must be  tightened.
5. Once the chain is properly tensioned, turn the lock clockwise to secure the cover. Then return the lever to its original position.

Checking the brake deceleration
Check the coasting brake before each use. This brake is part of the saw’s safety system, which protects the operator from serious injury and damage to the saw.

1. Switch on the saw according to the instructions in the “On/Off” section.
2. Release the switch. The saw chain must stop within one second of releasing the switch. If this happens, the coasting brake is good and it is safe to use the saw. If the saw chain does not stop within one second, remove the battery and contact an authorized service centre to have the saw repaired and adjusted. In this case, never use the saw.

Checking the cover strip
Checking the cover strip is important to prevent kickback. The shape of the cover strip with a protective tip is designed to eliminate kickback. Regularly check the condition of the cover bar for damage, deformation, breakage, etc. Never use a saw with a damaged cover bar. There is a risk of serious injury.
Lubrication
Only use commercially available biodegradable chain saw oils recommended by the manufacturer or specified as appropriate to lubricate the chain. Do not use engine oils, waste oils or mineral oils. Lubricate before each use of the saw.

1. Press the edge of the lock to release the chain and pull out the lever that is part of the lock (Fig. D1).
2. Turn the lock counterclockwise until the sprocket cover is released (Fig. D2). Carefully remove the sprocket cover.
3. Apply oil to the chain and sprocket. Use an oiler for application. Always apply a reasonable amount. Too little or too much oil can adversely affect the saw’s performance and the result of its use.
4. Replacing the sprocket cover. Make sure that the tabs on the inside of the cover fit into the holes in the saw body (Fig. E4).
5. Turn the lock clockwise to secure the cover (Fig. E5). Then return the lever to its original position (Fig. E6).

Note: If the saw makes a rattling sound, the chain must be lubricated.

OPERATION

Otherwise, the guide bar may vibrate, which could cause injury to the operator.
Switch on the saw. Cut the desired object by pushing lightly on the saw and sliding it down. The chain speed should not decrease during cutting. The speed should remain constant.
If the chain speed decreases, reduce the pressure on the saw and the speed at which the saw moves.
If it is not possible to cut the object with a single cut, pull the saw back slightly and then continue cutting.
Stand upright and steady when cutting. Keep your balance throughout the cutting process. Do not lean, bend or stand on one leg, etc.
Do not handle the cover bar while the saw is in operation. There is a risk of serious injury.
Do not put your hands over the cover strip or under the protective plate. There is a risk of serious injury.
Do not cut if the chain is in contact with the workpiece as it may hit a foreign object. There is a risk of serious injury.
Loosen the workpieces before fastening them. Remove all foreign objects such as nails, screws, etc.
Keep body parts out of the reach of the saw, especially the chain, while it is in operation.
Always hold the saw with both hands.
When cutting a branch that stretches, pay attention to it springing back. When the tension in the wood fibers is released, the sprung branch can hit the operator and/or you may lose control of the saw.
Take extra care when cutting shrubs and young trees. Thin branches can catch on the chain, which can throw them towards the operator or throw the operator off balance.
Do not overthrow or throw the saw.
Do not cover the ventilation holes.
Carrying the saw
When carrying the saw, always turn it off first and remove the battery. Then put on the chain guard.

Warning: Do not use petrol, thinner, alcohol or other similar substances for cleaning. There is a risk of surface damage, deformation or cracking.
Chain grinding
The chain must be sharpened when:

• The structure of sawdust has changed, and it is powdery;
• more pressure needs to exerted when cutting;
• it is not possible to cut straight;
• the saw excessively vibrates.

A blunt chain must be sharpened. Use a chain grinder to grind the chain. Make sure the grinding angle is 30°. If in doubt, have the chain sharpened by an authorized service centre.
If the chain is damaged, it must be replaced. Contact an authorized service centre.
Cleaning the guide rail
Sawdust and wood chips can accumulate in the groove of the guide rail. These can block the guide rail groove and impair oil flow. Regularly remove sawdust and wood chips (Fig. H).
Cleaning the sprocket cover
Sawdust and wood chips can accumulate inside the sprocket cover. Remove the cover and clean the interior (Fig. I).
