GENERAL SAFETY CONDITIONS

NOTE! Get acquainted with all the instructions below. Failure to observe them may lead to an electric shock, fire or injuries. The notion of electric tool used in the instructions applies to all the tools which are powered with electric current, both wire tools and wireless ones.

OBSERVE THE FOLLOWING INSTRUCTIONS

Place of work

The place of work must be properly illuminated and clean. Disorder and poor illumination may be a cause of accidents.

Do not work with electric tools in explosive environments, or those which contain inflammable liquids, gases or vapours.

Electric tools generate sparks, which may cause a fire in case of contact with inflammable gases or vapours.

Do not allow children and outsiders to the place of work. A lack of concentration may result in a loss of control over the tool.

Electric safety

The plug of the power supply cable must fit the mains socket. Do not modify the plug. Do not use any adapters whatsoever in order to adapt the plug to the socket. Unmodified plug which fits the socket reduces the risk of an electric shock.

GB

Avoid contact with grounded surfaces, such as pipes, heaters and refrigerators. Grounding of the body increases the risk of an electric shock.

Do not expose electric tools to precipitation or humidity. Water and humidity which gets into the electric tool increases the risk of an electric shock.

Do not overload the power supply cable. Do not use the power supply cable in order to carry the tool or to connect and disconnect the plug from the mains socket. Avoid contact of the power supply cable with heat, oils, sharp tools and moving elements. Damage to the power supply cable increases the risk of an electric shock.

In case work is realised outside closed areas, it is necessary to use extension cords designed for applications outside closed areas. Using a correct extension cord permits to reduce the risk of an electric shock.

If operating a power tool in a damp location is unavoidable, use a residual current device (RDC) protected supply. Use of an RCD reduces the risk of electric shock.

Personal safety

Commence work in good physical and psychological conditions. Pay attention to what you do. Do not work if you are tired or under effects of medicines or alcohol. Even a moment's inattention during work may lead to serious injuries.

Always use individual means of protection. Always wear goggles. Using individual means of protection, such as dust-masks, protective shoes, helmets and hearing protections permits to reduce the risk of serious injuries.

Avoid accidental activation of the tool. Make sure the switch is in the OFF position, before you connect the tool to the mains. Holding the tool with a finger on the switch or connecting an electric tool when the switch is in the ON position may lead to serious injuries.

Before you turn an electric tool on remove all the spanners and other tools, which have been used for adjustments. A spanner left on rotating elements of the tool may lead to serious injuries.

Keep your balance. Maintain an appropriate position. It will permit to control the electric tool in case of unpredicted situations during its operation.

Use protective clothes. Do not wear loose clothes or jewellery. Keep your hair, clothes and gloves away from moving elements of the electric tool. Loose clothes, jewellery or long hair may get caught on moving elements of the tool.

Use dust extractors or dust containers, if the tool is equipped with any. Make sure they are properly connected. Using of dust extractors permits to reduce the risk of serious injuries.

Operation of the electric tool

Do not overload the electric tool. Use a proper tool for the given purpose. A correct selection of the tool for the given work will result in a more efficient and safer work.

Do not use the electric tool if the switch is not functioning properly. A tool which may not be controlled by means of a switch is dangerous and must be repaired.

Disconnect the plug from the mains socket before any adjustment, replacement of accessories or storage of the tool. It will permit to avoid accidental activation of the electric tool.

Store the tool away from children. Do not allow untrained persons to operate the tool. An electric tool may be dangerous in hands of an untrained person.

Make sure the tool is properly maintained. Check the tool in order to detect any unfitting or loose moving elements. Check whether the elements of the tool are not damaged. In case any damaged elements of the tool are detected, they must be repaired before the electric tool is operated. Many accidents are caused by improper maintenance of tools.

Cutting tools must be sharp and clean. Properly maintained cutting tools are easier to control during work.

Use electric tools and accessories in accordance with the aforementioned instructions. Use the tool in accordance with its purpose, taking into account the kind and conditions of work. Should the tool be used for other applications than the ones it has been designed for, the risk of a dangerous situation increases.

Repairs

The tool may be repaired only by authorised service centres, which must use solely original spare parts. It will guarantee a proper level of safety of operation of the electric tool.

ADDITIONAL SAFETY GUIDELINES

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 fixing 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.

GB

Keep the sawing machine by insulated surfaces provided for this purpose during tasks, when the saw touch live conducts 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 fixing holes (e.g. rhomboidal or circular holes). Saws which do not fit the chuck may work eccentrically, leading thus to a loss of control over the tool.

To fix the saw do not ever use damaged or inadequate washers or bolts. Washers and bolts which fix 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 movement 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 recoil. 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 firmly 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 objects, 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 fix 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 on the floor. 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 misalignment 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.

GB

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.

INSTALLATION OF THE EQUIPMENT

ATTENTION! The equipment may be installed only if the power supply if off. Remove the plug of the cable the tool from the mains socket!

The sawing machine is supplied complete. Once the package has been opened, make sure all the elements have been supplied. Then check the connections and if necessary tighten the bolt connecting the base to the fixed guard and tighten the tighten bolts fixing the splitting edge, if the sawing machine is equipped with a wedge. Before first use, install the circular saw.

PREPARATION FOR WORK

Before work may commence, make sure the body and the power supply cable with plug are not damaged. In case any damage is detected, it is prohibited to continue work.

Attention! All activities related to installation and replacement of the circular saws, adjustments and maintenance of the electric tool must be realised when the sawing machine is not powered, so before such tasks: Remove the plug of the cord of the sawing machine from the mains socket!

Circular saw

Make sure the installed disc is not damaged, the cutting teeth are not broken, etc. In case any damage is detected, it is required to replace the circular saw with a new one.

Do not use damaged or deformed circular saws!

Do not use circular saws made of high-speed steel!

Do not use abrasive discs!

Do not use discs which do not comply with the technical parameters indicated in this manual!

Do not use saws, whose body is thicker or whose set is smaller than the thickness of the splitting edge!

Do not use discs whose maximum acceptable rotational velocity is lower than 5500 rpm.

Select a circular saw designed for cutting of the given material. The more teeth hast the saw circular saw, the smoother the edges of the saw cut will be. Saws with dozens of teeth are better suited for cutting of thinner materials, whose thickness is below 1 cm and for soft wood.

Attention! Do not cut other materials than those indicated in the manual.

Installation and replacement of the circular saw (II)

Attention. During replacement or installation of the saw, it is prohibited to dismantle the guards of the saw!

Use a wrench to block the fi xing disc of the circular saw and unscrew the bolt using another wrench.

Remove the fixing disc and the circular saw of the spindle of the sawing machine.

Install a new saw on the spindle.

Install the fixing disc, tighten the bolt, using the wrenches designed to install the saw.

Adjustments of the cutting depth (III)

If required, the tool permits adjustments of the cutting depth, which is facilitated by the scaled guide (located at the back of the tool). In order to do so, it is required to unscrew the lock located on the scaled guide, set the required cutting depth and lock the bolt.

Adjustments of the cutting angle (IV)

The tool permits cutting of planes at an angle between 0 and 45°. Set the required angle on the scale located at the front of the tool and tighten the locking bolt.

Installation of the guide

The scaled guide facilitates cutting of surfaces along a straight line. The guide must be fixed in the base, and then set the required cutting width and tighten the locking bolt.

Additional remarks

Do not use your hands to remove debris, slivers and other parts of the processed material from the surroundings of a rotating circular saw.

Do not use the sawing machine in exteriors during rain and other precipitations.

Do not guide the sawing machine just with your hands. Always use additional instruments, which permit to guide the sawing

GB

machine in a safe manner, such as a guide.

Once the circular saw has been checked and safely fixed, the depth, the angle and the width of cutting have been adjusted, do the following:

Make sure the moving guards work freely and do not jam.

Do not block the movement of the guards in the open position.

Make sure all the rotating mechanisms of the guards are functioning correctly.

Make sure the splitting edge is set correctly and:

• it is aligned with the circular saw,
• it is not wider than the width of the circular saw,
• the distance between the splitting wedge and the edge of the toothed disc does not exceed 5 mm,
• the edge of the toothed disc does not protrude by more than 5 mm beyond the lower edge of the splitting edge.

Always use the splitting edge! (in case of the sawing machines equipped with a splitting edge)

Do not dismantle the splitting edge, which protects the circular saw and the tool from damage.

Wear an eye protection, a hearing protection and working gloves. Use dust masks.

Attention! In case of tasks realised with manual sawing machines, always use hearing protection.

Fix the object to be processed to the workstation (e.g. using clamps or an anvil, etc.).

In case of cutting surfaces made of a hard wood (oak, beech, hornbeam), it is recommended to connect an external device collecting the dust generated during the task to the dust extraction orifice

USING THE TOOL

The sawing machine may be connected to the mains once all the actions indicated in „Preparation for work” have been realised.

Adopt a secure and stable position.

Hold the sawing machine in both hands, by the handle and the additional handle (V).

Turn the sawing machine on, pressing the lock of the switch and then the switch itself (VI).

Once the sawing machine has been turned on, keep it freely for a couple of seconds and listen to make sure it is functioning in a regular manner. In case any irregular sounds are emitted, stop working immediately and repeat the actions indicated in „Preparation for work”.

Put the base of the sawing machine on the surface of the object to be processed so as the disc does not touch the object (VII).

Once the switch has been pressed, wait until the circular saw has reached the nominal rotation and only then start cutting. It is prohibited to put the saw at the material and only then start the tool. This might cause jamming of the saw, its damage or damage the material, as well as lead to injuries.

In case cutting is resumed, let the circular saw reach the nominal rotation and then insert it in the kerf.

During cutting the circular saw must be led with smooth movements. Avoid excessive pressure. The pressure against the cutting head should not exceed the pressure which is sufficient to cut the material. It is required to avoid hitting with the circular saw against the material being cut.

Attention! Do not manipulate the mobile guard of the saw circular saw. All actions related to cutting must be realised holding the sawing machine with both your hands.

Lead the sawing machine along the cutting so that the base of the sawing machine is touching the surface of the processed object.

If the saw jams in the material being processed, turn the sawing machine off immediately, pressing the lock button and the switch, and only then remove the sawing machine from the kerf. During cutting pay particular attention to the possibility of slipping or recoil of the sawing machine, and beware of dangers that may lead to accidents. During work do not exert excessive pressure on the processed material and do not make rapid movements so as not to damage the circular saw and the sawing machine. Make regular breaks during work.

Avoid overloading the tool – the temperature of the external surfaces must not exceed 60^ C.

Once the task has been concluded, turn the sawing machine off, remove the plug of the tool from the mains socket and inspect the machine.

The declared total value of vibration has been determined by means of a standard measurement method and may be used to compare the tool with another one. The declared total value of vibration may be used for an initial evaluation of exposure.

Attention! The vibration caused during work with the tool may differ from the declared value, depending on the way in which the tool is used.

Attention! It is required to determine safety measures to protect the operator, based on evaluation of exposure under actual circumstances of operation of the machine (including all the phases of the working cycle, for example the time when the tool is off or is idling, and the activation time).

MAINTENANCE AND OVERHAUL

ATTENTION! Before any adjustment, technical service or maintenance operations unplug the tool. Once the operations have been finished, 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 deflection, 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.
