SAFETY WARNINGS FOR RECIPROCATING SAWS

Hold the power tool by its insulated grip surfaces while performing operations where the cutting part may come into contact with concealed cables. If the cutting part comes into contact with live cable, it may cause the exposed metal parts of the power tool to become live and electrocute the operator.

Use clamps or other practical means to securely fasten and support the workpiece on a stable platform. Holding the workpiece with your hand or pressed against your body makes it unstable and can lead to loss of control.

EQUIPMENT INSTALLATION

CAUTION! Only install the equipment when the supply voltage is disconnected. Remove the battery from the power tool socket!

The saw is supplied complete. After opening the packaging, check that all accessories are included.

PREPARING FOR WORK

Caution! All activities related to the assembly and replacement of saw blades, adjustment and maintenance of the power tool should be carried out with the power supply to the tool switched off. Therefore, before proceeding with these activities: Remove the battery from the power tool socket!

PREPARING FOR WORK

CAUTION! All operations mentioned in this section must be done with the power supply disconnected – the battery must be disconnected from the tool!

Safety instructions for battery charging

Caution! Before starting charging, make sure that the power unit body, cable and plug are not cracked or damaged. It is forbidden to use a defective or damaged charging station and power unit! Use only the supplied charging station and power unit to charge the batteries. The use of another power unit may result in fire or damage to the tool. The battery should only be charged in a closed, dry room, protected against unauthorised access, especially by children. Do not use the charging station and power unit without the constant supervision of an adult! If you need to leave the room where the product is being charged, disconnect the charger from the mains by removing the power unit's plug from the mains socket. If smoke, suspicious odours, etc. are escaping from the charger, remove the charger plug from the mains socket immediately!

The device is supplied with an uncharged battery and should therefore be charged according to the procedure described below with the included power unit and charging station before use. Li-ion (lithium-ion) batteries do not have the so-called “memory effect”, which means they can be recharged at any time. However, it is recommended to discharge the battery during normal operation and then charge it to full capacity. If, due to the nature of work, it is not possible to use the battery in such a manner every time, it should be done at least every several work cycles. Never discharge any batteries by short-circuiting the battery plates, as this will cause irreparable damage! In addition, do not check the battery charge status by short-circuiting the electrodes and checking their sparking.

Storing the battery

Ensure the proper storage conditions to extend the battery's life. The battery can withstand approximately 500 charge-discharge cycles. Store the battery at a temperature ranging from 0^ C to 30^ C at a relative air humidity of 50%. Charge the battery to approx. 70% of its total capacity to store it for a longer period of time. In case of prolonged storage, the battery should be periodically charged once a year. Do not over-discharge the battery as this will shorten its life and may cause irreparable damage.

During storage, the battery will gradually discharge due to leakage. The self-discharge process depends on the storage temperature – the higher the temperature is, the faster the discharge process is. If the batteries are stored incorrectly, the electrolyte may leak. In case of leakage, secure the leak with a neutralising agent. In the case of electrolyte contact with eyes, rinse eyes thoroughly with water, and immediately seek medical attention. It is not allowed to use the tool with a damaged battery. If the battery is completely worn, return it to a specialist waste disposal centre.

Transporting the batteries

Lithium-ion batteries are treated as hazardous goods according to legal regulations. The user of the tool can transport the product together with the battery and the batteries alone by land. In that case, no additional conditions have to be met. If you entrust transport to third parties (e.g. a courier company), follow the regulations regarding the transport of hazardous goods. Before shipping, please contact a properly qualified person.

EN

It is not allowed to transport damaged batteries. For the duration of transport, remove the demountable batteries from the product and secure the exposed contacts, e.g. by covering them with insulation tape. Protect the batteries in the packaging in such a way that they do not move inside the packaging during transport. National regulations for the transport of hazardous materials must also be observed.

Charging the battery

Caution! Before charging, disconnect the charging station power unit from the mains by removing the plug from the mains socket. In addition, clean the battery and battery clamps of dirt and dust with a soft, dry cloth.

The battery has a built-in charge indicator. The LEDs will light up by pressing the button. The more of them come on, the more charged the battery is. If the LEDs do not light up when the button is pressed, the battery is discharged.

Disconnect the battery from the tool.

Slide the battery into the charger socket (II).

Plug the charger into a mains socket.

The red LED will light up, which indicates the charging process.

When charging is complete, the red LED will turn off and the green LED will light up to indicate that the battery is fully charged.

Pull the power unit plug out of the mains socket.

Pull the battery out of the charging station by pressing the battery latch button.

Caution! If the green LED lights up when the charger is connected to the mains, the battery is fully charged. In this case, the charger will not start the charging process.

Blade installation and replacement (III)

Check that the saw blade installed is not damaged or cracked, and that the cutting teeth are not broken. If any damage is found, replace the saw blade with a new one.

The blades vary depending on their intended use. The saw blade for wood and wood-based materials has wider teeth and the saw blade for metal and plastics has finer teeth. An appropriate saw blade should be selected for the planned work. The blade can be mounted with the teeth facing downwards or upwards.

Caution! Wear protective gloves while fitting the saw blade. This will reduce the risk of injury.

Turn the spindle clamp and insert the blade holder into the spindle slot. Turn the clamp in the opposite direction and make sure that the blade is correctly clamped: the clamp has returned to its original position, the blade cannot be pulled out of the spindle.

USING THE TOOL

Before starting work, make sure that the saw blade is not damaged and is installed correctly. Wear eye protection, hearing protection and work gloves. Attach the workpiece to a workstation, e.g. by means of clamps, vices, etc. Never hold the workpiece only with hands or other body parts. In the case of cutting, support the material at its ends and near the cutting line. Support legs should be placed on both sides of the cutting line so that the saw blade does not jam in the cut when cutting. When cutting, the foot must rest with its entire surface against the material being cut.

Switching the sabre saw on and off

At the workplace make sure that the surface is level, stable and free of dirt.

Adopt a firm and stable posture.

Grasp the tool by the handle. Do not lean the working parts of the tool against any item or object.

Slide and hold the switch lock, press the switch with your finger and hold it. Check that the saw blade moves freely and that the tool does not begin vibrating in a suspicious or excessive manner. There is no smoke or suspicious smell coming from it. If any deviation from correct operation is observed, switch off the tool, disconnect the plug from the mains supply and take it to an authorised repair centre.

It is not necessary to hold the switch lock during operation.

The device is switched off by releasing the switch. The saw blade may still move for some time after it is switched off.

Cutting wood (IV)

Before starting to cut, draw a cutting line with a carpenter's pencil. Next, lean the tool against the foot and align the blade according to the drawn line, then switch on the tool, let the tool reach its rated rpm and start cutting. When cutting, do not exert too much pressure on the foot and on the blade, as this may cause the work tool to break. The foot has the ability to pivot to a certain extent, so that the angle of cut of the blade can be changed without detaching the foot from the material being cut.

Plunge-cutting

Caution! Plunge cutting is only allowed in soft materials such as soft wood or plasterboard. Never plunge cut into metal or other hard material.

EN

Use a short blade for plunge cutting. Set the maximum speed. Rest the edge of the foot against the material to be cut and switch on the tool. By applying pressure, allow the blade to plunge into the material until the foot fully rests against the material being cut. Continue cutting along the designated line.

When cutting through wood, start cutting at a lower speed and increase the speed as you cut.

Cutting at the edge

Caution! Special blades with increased flexibility should be used for edge cutting.

It is possible to cut right up against walls, floors and other hard-to-reach areas. For example, when cutting off pipes. When cutting, make sure that the blade will continuously pass through the total cross-section of the material being cut. It is forbidden to cut around the wall, this may cause the tool to bounce towards the operator. It is recommended to mount the blade rotated 180 degrees from its normal position. This will ensure easier cutting through.

Cutting holes

Caution! To cut holes, use blades designed for cutting curves.

Before starting work, the cutting line should be drawn. A hole is then drilled with a drill, and a saw blade is inserted into the drilled hole and the cutting begins.

Cutting through metal

Caution! It is important to select the right type of blade for the type of metal being cut. This will ensure greater operational safety and prolong the life of the blade.

When cutting through thin sheets of metal, it should be placed between two pieces of wood. This will produce a smooth cutting line and reduce the vibrations generated during operation. The use of a coolant suitable for the type of metal is recommended. If possible, a thin oil film should be spread over the area where the saw foot will move. This will make it easier to operate the saw.

Additional notes

Do not overload the tool, the temperature of the external surface must never exceed 60°C.

When work is done, switch off the tool, remove the plug from the mains socket and carry out maintenance and visual inspection.

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.
