Keep all warnings and instructions for future reference. The term “power tool” used in warnings applies to all tools driven by power both wired and wireless. Workplace safety15

ORIGINAL INSTRUCTIONS Keep the workplace well-lit and clean. Disorder and poor lighting can be causes of accidents. Do not work with power tools in an environment with an increased risk of explosion, containing fl ammable liquids, gases or vapors. Power tools generate sparks that can ignite dust or fumes. Children and third persons should not be allowed to enter the workplace. Loss of concentration can result in loss of control. Electrical safety The plug of the electric cable must match the power socket. You must not modify the plug in any way. Do not use any plug adapters with earthed power tools. An unmodifi ed plug that fi ts the outlet reduces the risk of electric shock. Avoid contact with earthed surfaces such as pipes, radiators and coolers. Grounding the body increases the risk of electric shock. Do not expose power tools to contact with atmospheric precipitation or moisture. Water and moisture that gets inside the power tool increases the risk of electric shock. Do not overload the power cable. Do not use the power cord to carry, pull or unplug the power plug from the power outlet. Avoid contact of the power cable with heat, oils, sharp edges and moving parts. Damage or entanglement of the power cord increases the risk of electric shock. In the case of working outside closed rooms, use extension cords intended for work outside closed rooms. The use of an extension cord adapted for outdoor use reduces the risk of electric shock. When using a power tool in a humid environment is unavoidable as a protection against supply voltage use a residual current device (RCD). The use of RCD reduces the risk of electric shock. Personal safety Stay alert, pay attention to what you do and keep common sense while working with the power tool. Do not use a power tool when you are tired or under the infl uence of alcohol or medication. Even a moment of inattention while working can lead to serious personal injury. Use personal protective equipment. Always wear eye protection. The use of personal protective equipment such as dust masks, anti-slip safety shoes, helmets and hearing protection reduce the risk of serious personal injury. Prevent accidental operation. Make sure that the electric switch is in the “off ” position before connecting to the power supply and / or battery, lifting or moving the power tool. Moving the power tool with the fi nger on the switch or powering the power tool, when the switch is in the “on” position can lead to serious injuries. Before turning on the power tool remove any keys and other tools that were used to adjust it. The key left on the rotating parts of the power tool can lead to serious injuries. Do not reach and do not lean too far. Keep the right attitude and balance all the time. This will allow easier control over the power tool in case of unexpected work situations. Dress accordingly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts of the power tool. Loose clothing, jewelry or long hair can be caught by moving parts. If the devices are fi tted for the connection of dust extraction or dust collection, make sure that they are connected and used properly. The use of dust extraction reduces the risk of dust hazards. Do not let the experience acquired from frequent use of the tool resulted in carelessness and ignoring safety rules. Carefree action can cause serious injuries in a fraction of a second. Use and care of the power tool Do not overload the power tool. Use the power tool appropriate for the selected application. The right power tool will pro- vide a better and safer job if used according to the designed load. Do not use the power tool, if the electric switch does not allow switching on and off . Power tool, which cannot be controlled by means of a power switch is dangerous and must be returned for repair. Disconnect the plug from the power socket and / or remove the battery if it is detachable from the power tool before adjusting, changing accessories or storing the tool. Such preventive measures will allow you to avoid accidentally turning on the power tool. Keep the tool out of the reach of children, do not let people who do not know how to operate the power tool or these instructions use a power tool. Power tools are dangerous in the hands of untrained users. Maintain power tools and accessories. Check the tool for mismatches or jams of moving parts, damage to parts and any other conditions that may aff ect the operation of the power tool. Damage must be repaired before using the power tool. Many accidents are caused by incorrectly maintained tools. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp edges are less prone to jamming and are easier to control when working. Use power tools, accessories and inserted tools etc. in accordance with these instructions, taking into account the type and conditions of work. The use of tools for work other than designed is likely to result in a dangerous situation. Handles and gripping surfaces must be dry, clean and free from oil and grease. Slippery handles and gripping surfaces do not allow for safe operation and control of the tool in dangerous situations. Repairs Repair the power tool only in authorized facilities using only original spare parts. This ensures proper operation safety of the power tool

ORIGINAL INSTRUCTIONS Safety recommendations regarding sawing machines Keep hands away from the cutting area and the saw. Keep the other hand on the additional handle or the motor casing. If the sawing machine is kept with both hands, then they may be exposed and injured. Do not reach under the object being processed with your hands. The guard may not protect you from the saw below the object being processed. Adjust a cutting depth which is adequate for the thickness of the object being processed. It is recommended to make sure the disc protrudes below the material being cut by less than the height of a tooth. Do not ever keep the material being cut in your hands or support it on your leg. Fix the object to be processed to a stable base. Adequate fi xing of the object to be processed is crucial to avoid the danger of any contact with the body, seizure of the saw or a loss of control over the cutting process. Keep the sawing machine by insulated surfaces provided for this purpose during tasks, when the saw touch live con- ducts or its own power supply cable. Any contact with „live conducts” may also cause the metal parts of the tool to be live, which might cause electric shock to the operator. During longitudinal cutting always use the guide for longitudinal cutting or the guide for edges. This will enhance the precisions of cutting and reduce the possibility of seizure of the saw. Always use saws of correct dimensions and shape of the fi xing holes (e.g. rhomboidal or circular holes). Saws which do not fi t the chuck may work eccentrically, leading thus to a loss of control over the tool. To fi x the saw do not ever use damaged or inadequate washers or bolts. Washers and bolts which fi x the saws have been specially designed for the sawing machine, to ensure its optimum functioning and safety of use. Causes and prevention of recoil Recoil is a sudden reaction to a squeezed, stopped or misaligned circular saw, and it causes an incontrollable lifting and move- ment of the sawing machine towards the operator. If the saw is squeezed or stopped during cutting, then the edge is locked and the reaction of the motor causes a sudden movement of the sawing machine towards the operator. If the saw is deformed or is misaligned, then the teeth and the rear edge may come out of the saw cut and move towards the operator. Backward recoil is a result of inadequate operation of the sawing machine or incorrect procedures or operating conditions and it may be avoided adapting necessary safety measures, which are indicated below. Keep the sawing machine with strength using both your hands, with the arms in a position that will resist a backward re- coil. Adapt a position of the body at one side of the sawing machine, but not in the cutting line. Backward recoil may cause a sudden movement of the sawing machine, but the strength of backward recoil may be controlled by the operator, if adequate precautions have been taken. When the saw jams or when cutting is interrupted for any reason, release the button and keep the sawing machine still in the material until the disc has completely stopped. Do not ever try to remove the sawing machine from the material which is being cut, or pull the sawing machine backwards while the saw disc is moving or may cause backward recoil. Inspect the causes and take corrective actions, in order to eliminate the reasons why the saw jams. If the cutting with sawing machine is resumed in the same element, then centre the disc saw in the saw cut and make sure the teeth of the saw are not caught in the material. If the disc saw jams when the sawing machine is set in motion again, then it may come out or cause backward recoil in relation to the element being processed. Support large boards, in order to minimise the risk of jamming and backward recoil of the disc. Large boards tend to bend under their own weight. Supports should be placed under the board at both sides, close to the cutting line, next to the edges of the board. Do not use blunt of damaged saws. Blunt or inadequately positioned teeth of the saw form a narrow saw cut which leads to excessive friction, jamming of the saw and backward recoil. Before cutting may commence, it is required to close fi rmly the cutting depth and the saw inclination angle clamps. If the settings of the sawing machine change during cutting, then there is a risk of jamming and backward recoil. Be particularly careful during deep cutting into existent walls or other spaces. A protruding saw may be cutting other ob- jects, causing backward recoil. Additional safety recommendations for sawing machines Before each use make sure the lower guard is in a correct position. Do not use the sawing machine, if the lower guard does not move freely and close immediately. Do not ever fi x the lower guard or leave it open. If the sawing machine is dropped accidentally, the lower guard may bend. Lift the lower guard by the handle and make sure it moves freely and does not touch the saw or another part at any angle and cutting depth. Check the spring of the lower guard. If the guard or the spring do not function properly, they must be repaired before being used. The lower guard may be slow if the parts are damaged, if there are sticky residues or if waste is accumulated. It is acceptable to manually retract the lower guard only in case of special cutting tasks, such as „deep cutting” and „complex cutting”. Lift the lower guard by the handle and once the saw enters the material, release the lower guard. In any other case it is recommended to make sure the lower guard functions automatically. Always make sure the lower guard covers the saws, before the sawing machine is placed on the workshop table or on17

ORIGINAL INSTRUCTIONS the fl oor. if the edge of the saw is unprotected, the sawing machine will retract cutting anything it contacts accidentally. Remember the saw needs time to come to a halt, once the machine is turned off . Additional safety instructions for sawing machines with a splitting wedge Use an appropriate splitting edge for the given saw. The splitting edge must be thicker than the body of the saw, but thinner than the distance between the teeth of the saw. Adjust the splitting edge in accordance with the description in this manual. Incorrect setting, a wrong position or misalign- ment may make the splitting edge useless in the context of prevention of backward recoil. Always use a splitting, except for deep cutting. The splitting edge must be installed again after deep cutting. The splitting edge causes disturbance during deep cutting and may cause backward recoil. In order to function correctly, the splitting edge must be introduced into the element being processed. The splitting edge is useless in prevention of backward recoil during short cuts. Do not operate the sawing machine, if the splitting edge is bent. Even slight bends may slower the closing of the guard.

ASSEMBLY OF EQUIPMENT

ATTENTION! The installation of the equipment may be done only with disconnected power supply. Remove the battery pack from the power tool socket! The saw machine is supplied complete, After opening the factory packaging you should check whether all items were packed. Then check the connections status and, if necessary, tighten the screw connecting the base with fi xed guard and tighten the screws, which are fastening the splitting wedge, if the saw machine is equipped with it. Before the fi rst use, you should mount the circular saw blade.

PREPARING FOR OPERATION

Before starting any work you should check whether the housing and the battery are not damaged. In the case of damage any further work is prohibited. Attention! All activities associated with the installation and replacement of circular saw blades, their adjustment and the maintenance of a power tool must be carried out when the operating voltage of the saw machine is switched off , therefore, before the further proceedings, you should carry out the following steps: Remove the battery pack from the power tool socket! ATTENTION! All the operations mentioned in this point must be realised with the power supply off . - the battery must be disconnected from the tool! Safety recommendations for battery loading Attention! Before loading may start make sure the body of the charger, the cable and the plug are not broken or damaged. It is prohibited to use a damaged loading dock and charger! For the purpose of loading batteries only the charging dock and the charger provided may be used. Using another charger may be a cause of fi re or damage the tool. Batteries may be charged only in a dry room, protected from unauthorised persons, particularly children. Do not use the charging dock and the charger without permanent supervision of an adult! If it is necessary to leave the room where loading is taking place, it is required to disconnect the charger from the mains, removing the charger from the mains socket. In case when smoke comes out of the charger, or a strange smell is emitted, etc., it is required to immediately remove the plug of the charger from the mains socket! The drill and automatic return screwdriver is provided with an unloaded battery, so before work may commence, it is required to charge it following the procedure below, using the charger and charging dock provided. Li-ION batteries do not show the so called “memory eff ect”, so it is allowed to charge them at any moment. However, it is recommended to discharge them during normal work, and then load them to their full capacity. If due to the nature of the task it is not possible to do so each time, then it is required to do it at least from time to time. Under no circumstances is it allowed to discharge the batteries short-circuiting the electrodes, since this would cause irreversible damage! It is also prohibited to check the load of the batteries, short-circuiting the electrodes for sparking. Storage of the battery In order to prolong the life of the battery, it is required to provide adequate storage conditions. The batteries can go through ap- proximately 500 „loading - discharging” cycles. The battery must be stored between 0 and 30°C, at the relative humidity of 50%. In order to store the battery for a prolonged period, it is required to charge it to approximately 70% of its capacity. In case of prolonged storage, it is required to recharge the battery once a year. Do not permit excessive discharging of the battery, since this would reduce its life and may cause irreversible damage. During storage, the battery will be gradually unloading due to leakage conductance. The process of automatic unloading depends18

ORIGINAL INSTRUCTIONS on the temperature of storage, since the higher the temperature, the fastest the process. In case of incorrect storage of batteries, there is a danger of electrolyte leakage. In case of leakage, it is required protect the leakage with neutralizing agent. In case of contact of electrolyte with the eyes, it is required to rinse the eyes abundantly, and then immediately seek medical assistance. It is prohibited to use a tool with a damaged battery. In case the battery is completely worn out, it is required to deposit it at a special point dedicated to disposal of such waste. Transport of the batteries Lithium-ion batteries are in accordance with legal regulations treated as dangerous waste. The user of the tool may transport the tool with the battery or only batteries by land. Then no additional conditions must be complied with. In transport is realised by third parties (for example dispatch through courier service), then it is required to proceed in accordance with regulations for transport of dangerous materials. Before shipment, contact an authorised person. It is prohibited to transport damaged batteries. During transport the battery must be removed from the tool, and the exposed contacts protected, e.g. with insulating tape. Protect the batteries so that they do not move inside the package during transport. It is also required comply with the national regulations for transport of dangerous materials. Charging the battery Attention! Before charging you should disconnect the charger from the mains by unplugging the power supply plug from the mains. In addition, you should clean the battery and its terminals of dirt and dust with a soft, dry cloth. The battery has a built-in charge indicator. When you press the button, LEDs will light up (II), the more LEDs will light up, the more fully the battery pack is charged. If the button is pressed and the LEDs are off it means that the battery is discharged. Disconnect the battery from the tool. Push the battery in the charger socket (II). Plug the charger into a mains socket. When the red LED lights up, it means the loading process. When charging is complete, the red LED goes off , and green LED lights up, indicating a full charge of the battery. Unplug the charger from the mains outlet. Remove the battery from the charging station, by pressing the battery latch button. Attention! If, when the charger is connected to the power supply, the green LED is on, this indicates a fully charged battery. In this case, the charger does not start charging. Circular saws Select the circular saw, which is assigned for cutting the selected type of material. The more teeth has saw the smoother will be the edges of the cut. Saws, which are having dozens of teeth, are better suited for cutting thinner material, of a thickness of less than 1 cm and for soft wood. Attention! Do not cut other materials than those mentioned in the manual. You should check whether the blade is not damaged, cracked, whether the cutting teeth are not broken, etc. In the case of dam- age, replace the circular saw for a new one. Do not use saw blades which are deformed or cracked! Do not use saw blades made of high speed cutting steel! Do not use abrasive discs! Do not use saw blades which do not comply with the technical data specifi ed in this manual! Do not use saw blades, which body is thicker than the thickness of the splitting wedge! You should not use saw blades of a maximum acceptable rotational speed less than the rotational speed of the saw. Mounting and replacing of the saw blade (II) Attention! During exchange or mounting of the saw blade you should do not disassemble saw guards! You should lock the blade rotation and loosen the screw that secures the blade. Remove the mounting fl ange and circular saw from the saw spindle. Clean the spindle, the fi xing fl anges and the inside part of the covers of the dust and debris, which can be remaining after work. Install the mounting fl ange, and then install a new blade on the spindle. Install the external mounting fl ange, and then, by blocking ability of the saw blade to rotate, tighten the screw, which is fi xing the saw. Adjustment of the cutting depth (III) If necessary, the tool allows you to adjust the depth of cut, it is easier due to application of the guide with scale (placed on the back of the tool). To do this, you should, by using the screw, loosen the lock, which is placed on the guide with scale, then set the desired cutting depth and lock the screw. Adjusting the cutting angle (IV) The tool allows for cutting planes on angle ranging from 0 to 45

. To do this, you should set the desired angle on scale placed on the front of the tool and tighten fi rmly and securely the locking screw.19

ORIGINAL INSTRUCTIONS Installation of the guide (V) The guide with a scale facilitates cutting surface in a straight line. The guide should be mounted in the base, then set for the desired cutting width and, after that, lock the screw. Additional notes Do not use your hands to remove loose pieces, splinters and similar parts of the workpiece from the surroundings of rotating saw blade. Do not use the saw outdoors during the rain or other atmospheric precipitation. Do not guide the saw only by hands. Always use the auxiliary instruments, which will allow for sure running of the saw, such as guide. After checking the saw blade and its fi rm mounting, setting the depth, the angle and width of cutting you should also: Make sure, that movable guards can operate freely, without blocking themselves. Do not lock the mobile guard in its open position. Make sure, that all rotary mechanisms of the guard system are working properly. In saw machines, which are equipped with a splitting wedge, you should make sure that the splitting wedge is adjusted in such a way, that: - distance between the splitting wedge and a fl ange of the blade with the teeth is not greater than 5 mm, - crown of the blade with the teeth does not protrude for more than 5 mm further of the bottom edge of the splitting wedge, - it is located in the line of the rotating disc, - it is not wider than the width of the saw blade. You should always use the splitting wedge! (in saw machine models equipped with a factory made splitting wedge) Do not disassemble the splitting wedge, that protects the circular saw and the tool against its damage. Wear eye protection, hearing protectors and working gloves. Wear a dust mask. Attention! When you are working with manual saws your should always use a hearing protection. Secure the workpiece to the workplace (e.g. by using carpentry clamps, vice, etc.). In the case when you are cutting surface made from hard wood (oak, beech, hornbeam) it is recommended to connect an external device to collect dust the dust which is produced during processing to the hole for a dust extraction.

OPERATING OF THE TOOL

Connecting the saw to the mains may be carried out only after you have completed all of the steps listed in the section “ Preparation for work”. Adopt a stable stand. Grab the saw in both hands with the grip and additional handle (VI). Turn on the saw by pressing the button of lock switch, and then by pressing the electric switch (VI). During the operation it is not necessary to hold the lock button. When you turn on the saw, you should hold it freely for a few seconds and check the smoothness of its operation. In the event of any suspicious sounds, glitches, etc. you should immediately stop your operation and again follow the steps the sky in that chapter “Preparing for operation”. Place the saw base to the surface of a workpiece in such a way that the saw blade does not touch this item (VII). Attention! Do not manipulate the movable guard of the saw blade. All activities related to the cutting must be done when you are holding the saw with both hands. you should lead the saw along the cutting line so the base of the saw touches the surface of the workpiece. When the switch is pressed on, you should allow to reach, by the circular saw, the rated rotational speed and only then start the cutting. It is forbidden to press the saw to a material and only then run the tool. This can result in the blocking of saw, its failure or damage to the material. This can lead to a serious injury. In the case when you resume cutting, you must let the circular saw to achieve its nominal revolutions, and then enter it into the saw cut. During cutting with the circular saw it should be guided by a smooth motion, you should also avoid to apply an excessive pressure. Pressure on the cutting head should not to be greater than this, which is enough to cut material. Hitting with circular saw to the cut material should be avoided. If the saw locks itself in the workpiece, you should immediately turn off the saw by pressing the lock button and the electric switch and only after that you may withdraw the saw machine. At the time of cutting, you should pay particular attention to the possibility of slippage or recoil of the saw, and therefore, the risk of accident. During operation you should not exert too much pressure on the workpiece material and do not make sudden movements, in order to avoid damage to the circular saw and circular saw machine. Make regular breaks when working,.20

ORIGINAL INSTRUCTIONS Do not overload the tool, the outer surfaces temperature should never exceed 60

At the end of work you should turn off the saw machine, remove the plug from the mains socket, and make maintenance and in- spection. The declared, total declared value of vibration was measured by the standard test method, and it can be applied to compare one tool to another. Declared total value of vibration can was used in a preliminary assessment of exposure. Attention! The vibration emissions when working with the tool can diff er from the declared value, depending on how you use the tool. Attention! You should specify the security measures to protect the operator, which are based on an assessment of exposure in the actual conditions of use such as, for example, the time when the tool is turned off or it is idling, and its activation time).

MAINTENANCE AND OVERHAUL

ATTENTION! Before any adjustment, technical service or maintenance operations unplug the tool. Once the operations have been fi nished, the technical conditions of the tool must be assessed by means of external evaluation and inspection of the following elements: body and handle, conductor with a plug and defl ection, functioning of the electric switch, patency of ventilation slots, sparking of brushes, noise level of functioning of bearings and gears, start-up and smoothness of operation. During the guarantee period, the user cannot dismantle the electric tools or change any sub-assemblies or elements, since it will cancel any guarantee rights. All irregularities detected at overhaul or during functioning of the tools are a signal to have the tool repaired at a service shop. Once the functioning has been concluded, the casing, ventilation slots, switches, additional handle and protections must be cleansed with a stream of air (at a pressure not exceeding 0.3 MPa), with a brush or a cloth without any chemical substances or cleaning liquids. Tools and handles must be cleansed with a clean cloth.21 ORIGINALANLEITUNG
