GENERAL WARNINGS FOR THE SAFETY OF POWER TOOLS

Warning! Read all safety warnings, illustrations and specifications provided with this power tool. Failure to do so may result in electric shock, fire or serious injury.

EN

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 safety

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 flammable 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 unmodified plug that fits 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 influence 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 finger 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 fitted 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 provide 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 affect 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

EN

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.

SAFETY WARNINGS FOR DRILLS

Safety instructions for all activities

Use hearing protectors when hammer drilling. Exposure to noise can cause hearing loss.

Use the additional handle(s). Loss of control can cause personal injury.

Grasp the tool properly before use. This tool generates high torque and when it is not properly held during operation, loss of control can cause personal injury.

Hold the tool by the insulated handles when working where the cutting accessory may come into contact with the hidden cord or supply cable. Cutting accessory coming into contact with a live wire can cause the metal parts of the tool to become “live” and cause an electric shock to the operator.

Safety instructions when using long drill bits

Never operate at a higher rotational speed than the maximum drill bit rotational speed. At higher speeds, the drill bit will probably bend and cause personal injury if it is allowed to rotate freely without contact with the workpiece.

Always start working at low speed and when the end of the drill bit is in contact with the workpiece. At higher speeds, the drill bit will probably bend and cause personal injury if it is allowed to rotate freely without contact with the workpiece.

Apply pressure only in the direction of the drill bit axis. Do not apply excessive pressure. The drill bit can bend, causing breakage or loss of control which will result in personal injury.

PREPARING FOR WORK

CAUTION! All activities listed in this section must be carried out with the supply voltage 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, cord 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 tool is being charged, disconnect the charger from the mains by removing the power unit 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 drill driver 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 plates and checking their sparking.

Battery storage

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^ to 30^ 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, the faster the discharge process. 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.

Battery transport

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,

EN

please contact a properly qualified person.

It is prohibited 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 goods 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 (II); the more of them come on, the higher the charge level. 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, it means that the battery is fully charged. In this case, the charger will not start the charging process.

Setting rotational speed and selecting the torque

The cordless screwdriver has two mechanically-switched gears (III). Depending on the selected maximum rotational speed, select one of them. A gear that is characterised by a lower rotational speed is recommended for driving and removing the screws, while a gear that is characterised by a higher speed is recommended for drilling.

The torque is set by means of a ring placed behind the drill chuck (IV). The higher the setting, the higher the torque provided by the cordless screwdriver. Do not set a higher torque than is necessary to work properly. Otherwise, the threads can be damaged. If screws are driven directly into the material, the correct torque should be experimentally selected by carrying out a test on waste material. If the maximum torque that is safe for a given connection is not known, set the lowest value and then increase it until the proper value for a given work is reached. If the cordless screwdriver reaches the maximum set torque, the overload coupling will engage – after that stop driving the screw.

Behind the torque selection ring, there is a ring for selecting the drilling type. Setting the ring to the hammer symbol means hammer drilling.

Hammer drilling should be used to make holes in concrete and should not be used to make holes in wood or plastics.

Setting the ring to the drill bit symbol means normal drilling (non-hammer drilling). Setting the ring to the screw symbol means screw driving.

If the tool is to be used for drilling holes, the ring must be set to the drill bit or hammer symbol; the overload coupling will be disconnected and the maximum torque will be transferred to the drill bit.

Caution! Do not use the settings with numbers for drilling. Activation of the overload coupling during drilling may damage the material or the drill bit and increase the risk of injury.

Installing drill bits in the drill chuck

Select the drill bit with a cylindrical holder suitable for the work.

Insert the drill bit into the chuck. Tighten the drill chuck by hand until the drill bit is securely attached (VI).

Set the maximum torque. Set the torque ring to the drill bit or hammer symbol.

Setting the rotation direction

Set the rotation direction switch to the desired position. The direction of rotation is indicated by an arrow (VII). The arrowhead shows the movement direction of the drill bit and right-hand screws.

Caution! The direction of rotation must only be changed when the supply voltage is disconnected! Do not change the rotation direction during the operation of the drill driver!

Installing the screwdriver bits in the drill chuck

Insert the chuck for bits into the hole of the drill chuck, and then insert the bit suitable for work or install the bit directly into the chuck (VIII).

Installing the additional handle (IX)

Due to the high torque, always use the tool with the correctly attached additional handle.

EN

Mount the handle clamp on the tool housing, and then tighten the handle grip by tightening the clamp so that the handle is securely and firmly attached to the tool housing. Check the clamp periodically for loosening during operation.

Preparatory actions for operation

Before starting work:

Attach the workpiece in a vice or using G clamps.

Use working tools appropriate for the work to be carried out. Make sure that they are sharpened and in good condition.

Wear work clothing and eye and hearing protection equipment.

Grasp the tool with both hands (X).

Adopt a fi rm and stable posture.

Turn on the tool by pressing the electric power switch with your finger.

Caution! If you notice any suspicious noises, cracks, odour, etc. during operation, immediately turn off the tool and remove the battery from the tool.

USING THE TOOL

Caution! Use hearing protectors when using the tool!

Using the right-hand or left-hand rotation direction

Use right-hand rotation when drilling with commonly used right-hand drill bits.

Apply left-hand rotation in case of jamming of the right-hand drill bit in the material and when removing screws. When removing the screws, use a minimum rotational speed.

Drilling in wood

Before drilling a hole, it is recommended to fix the workpiece with G clamps or place it in a vice, and then use a punch or a nail to determine the place of drilling. Insert the correct drill bit in the drill chuck, set the torque, connect the tool to the battery and start drilling.

When making through holes, it is recommended to place a wooden pad under the material, so that the edge of the hole at the outlet will not be torn.

In the case of drilling holes with large diameters, it is recommended to drill a smaller guide hole beforehand.

Drilling in metals

Always fasten the workpiece securely. In the case of thin sheet metal, it is recommended to place a piece of wood under it to avoid unwanted bends, etc. Then mark the locations of holes with a punch and start drilling.

Use drill bits intended for steel. It is recommended to use sintered carbide drill bits when drilling in white cast iron. When drilling larger holes, it is recommended to make a smaller guide hole beforehand.

When drilling in steel, use general purpose lubricating oil to cool the drill bit.

For aluminium, use turpentine or paraffi n as a coolant.

Do not use cooling agents when drilling in brass, copper or cast iron. For cooling, remove the drill bit from the material frequently to allow it to cool down.

Drilling in hard, compact ceramic materials (concrete, hard brick, stone, marble, etc.)

Before drilling the correct hole, drill a smaller hole. Do not use the hammer drilling function for this operation. The correct hole should be drilled with the hammer drilling activated. Use sintered carbide hammer drill bits in good condition.

Drilling in glazed tiling, soft brick, plaster, etc.

Use hammer drill bits. Do not activate the hammer drilling function. During drilling, press the tool firmly with constant force. Remove the drill bit from the drilled hole from time to time to remove dust and waste.

Using the tool for driving or removing the screws

For this purpose, it is recommended to use the lowest possible rotational speed and use appropriate bits.

The bits can be installed directly in the drill chuck, or with a special magnetic chuck.

To remove the screw, change the rotation direction with the switch to the left-hand rotation.

Using attachments

The tool must not be used to drive work attachments.

Additional notes

When working, do not exert too much pressure on the workpiece and do not make sudden movements in order not to damage the drill bit and the drill.

Take regular breaks during work.

EN

Do not overload the tool, the temperature of the external surfaces must never exceed 60^ C.

After finishing work, turn off the drill, disconnect the battery and perform 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.
