DRILL SAFETY WARNINGS

Safety instructions for all activities

Wear hearing protection when hammer drilling. Exposure to noise can cause hearing loss.

Use an additional handle (grip). Loss of control can result in personal injury.

Hold the tool properly before use. This tool produces high torque and without proper grip during operation, loss of control may cause personal injury.

Hold the tool by insulated gripping surfaces when performing an operation where the insertion tool may contact a hidden wire or the power cord. Contacting a „live“ wire may cause metal parts of the tool to become „live“ and give the operator an electric shock.

Safety instructions when using long drill bits

Never operate at higher speed than the maximum speed rating of the drill bit. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.

Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.

Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend causing breakage or loss of control, resulting in personal injury.

Battery Charging Safety Instructions

Attention! Before charging, make sure that the charger body, cable and plug are not cracked or damaged. It is forbidden to use a faulty or damaged charging station and power supply! Only the charging station and power supply supplied in the set may be used to charge batteries. Using another charger may cause a fire or destroy the tool. The battery may only be charged in a closed, dry room protected from access by unauthorized persons, especially children. The charging station and power supply must not be used without constant adult supervision! If it is necessary to leave the room in which charging is taking place, disconnect the charger from the mains by unplugging the power cord from the mains socket. If smoke, a suspicious smell, etc. is emitted from the charger, immediately remove the charger plug from the mains socket! The tool is supplied with an uncharged battery, therefore before starting work it should be charged according to the procedure described below using the charging station and power supply supplied in the set. Li-Ion batteries (lithium-ion) do not exhibit the so-called „memory effect", which allows them to be charged 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 the work, it is not possible to treat the battery in this way every time, then it should be done at least every few or a dozen cycles of operation. In no case should batteries be discharged by short-circuiting the electrodes, as this causes irreversible damage! It is also forbidden to check the battery charge by short-circuiting the electrodes and checking for sparking.

Battery storage

To extend the battery life, ensure proper storage conditions. The battery can withstand about 500 charge-discharge cycles. The battery should be stored in a temperature range of 0 to 30 degrees Celsius, with a relative humidity of 50%. To store the battery for a longer period of time, it should be charged to about 70% of its capacity. In the case of longer storage, the battery should be charged periodically, once a year. Do not over-discharge the battery, as this will shorten its life and may cause irreversible damage. During storage, the battery will gradually discharge due to leakage. The process of self-discharge depends on the storage temperature, the higher the temperature, the faster the discharge process. If the batteries are not stored properly, electrolyte may leak. In the event of a leak, secure the leak with a neutralizing agent, in the event of contact of the electrolyte with the eyes, rinse the eyes thoroughly with water and then seek immediate medical attention. It is forbidden to use a tool with a damaged battery. When the battery is completely worn out, it should be taken to a specialist waste disposal facility.

Battery transportation

Lithium -ion batteries are considered hazardous materials according to legal regulations. The user of the tool can transport the tool with the battery and the batteries themselves by land. In this case, no additional conditions need to be met. In the event of entrusting transport to third parties (e.g. shipping by courier), the regulations for the transport of hazardous materials must be followed. Before shipping, contact a person with appropriate qualifications in this matter. It is prohibited to transport damaged batteries.

EN

During transport, dismantled batteries must be removed from the tool, and exposed contacts must be protected, e.g. covered with insulating tape. Secure 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.

Battery charging

Insert the battery into the charger socket (X).

Connect the charger to a wall outlet.

There is a charger operation indicator light near the battery socket, as described in the „Charger operation indicator” table. After charging is complete, disconnect the charger plug from the mains socket.

It is prohibited to use other batteries with a different rated voltage and which do not fit the device's battery socket. It is prohibited to modify the socket and/or battery to fit them.

Insert the battery into the power socket with the contacts facing the inside of the tool until the battery latch engages. Make sure the battery does not slide out during operation. Disconnect the battery by pressing and holding the latch, then sliding the battery out of the tool housing.

PREPARING FOR WORK

NOTE! All activities listed in this chapter must be performed with the supply voltage disconnected - the battery must be disconnected from the tool!

Setting the speed and selecting the torque

The screwdriver has two mechanically switched gears (II). Depending on the selected maximum rotational speed, one of them should be selected. The gear characterized by a lower rotational speed is recommended for tightening and loosening screws, while the gear characterized by a higher speed is recommended for drilling.

The torque is set using a ring located behind the drill chuck (III). The higher the number of settings, the higher the torque the screwdriver offers. Do not set a higher torque than necessary for correct operation. Otherwise, the threads may be damaged. When screwing screws directly into the material, the correct torque should be selected experimentally, by conducting 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 appropriate value for the work is reached. If the screwdriver reaches the maximum set torque, the overload clutch will engage, and tightening should then be stopped.

If the product is equipped with a hammer drilling function, it has a hammer symbol visible on the setting ring (IV). Setting the ring to the hammer symbol will engage the impact mechanism. Impact drilling should be used for drilling holes in concrete and should not be used for drilling holes in wood or plastics.

When using a tool to drill holes, set the ring to the drill or hammer symbol, this will disengage the overload clutch and transmit

EN

maximum torque to the drill.

Warning! Do not use the settings marked with numbers for drilling. Activation of the overload clutch during drilling can damage the material or the drill and increases the risk of injury.

Fixing drills in the drill chuck

Be sure to select the appropriate cylindrical shank drill for the job.

Insert the drill bit into the chuck. Tighten the drill chuck by hand until the drill bit is securely held (V).

Set the highest torque. Set the torque knob to the drill or hammer symbol.

Setting the direction of rotation

Set the direction of rotation switch to the desired position. The direction of rotation is indicated by an arrow (VI).

Attention! The direction of rotation can only be changed when the supply voltage is disconnected! The direction of rotation must not be changed during operation of the drill-driver!

Fixing screwdriver bits in the drill chuck

Insert the bit holder into the drill chuck hole and then insert the appropriate bit for the job or secure the bit directly into the holder (VII).

Installing the additional handle (VIII)

Due to the high torque, always use the tool with a properly attached auxiliary handle.

Screw the end of the additional handle into the hole in the tool housing. Tighten the handle so that it is securely fastened and does not loosen during operation.

Preparatory activities for work

Before starting work:

Secure the workpiece in a vice or using clamps.

Use work tools that are appropriate for the job at hand. Keep them sharp and in good condition.

Put on work clothes and eye and hearing protection.

Grasp the tool with both hands (IX).

Adopt a confi dent and stable stance.

Turn on the tool by pressing the electrical switch with your finger.

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

USING THE TOOL

Warning! Hearing protection must be worn when using the tool!

Using right or left rotation direction

Use clockwise rotation when drilling with commonly used right-handed drills.

Use left-hand rotation when a right-hand drill becomes jammed in the material and when removing screws. Use minimum rotation when removing screws.

Drilling in wood

Before drilling a hole, it is recommended to secure the workpiece with carpenter's clamps or in a vice, and then use a center punch or nail to determine the drilling location. Attach the appropriate drill bit to the drill chuck, set the torque, connect the battery to the tool and start drilling.

When making holes „through“ it is recommended to place a wooden pad under the material to prevent the edge of the hole at the exit from being jagged.

When making large diameter holes, it is recommended to drill a smaller pilot hole first.

Drilling in metals

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

Use drills for steel. When drilling white cast iron, it is recommended to use carbide-tipped drills. When drilling larger holes, it is recommended to make a smaller pilot hole first.

When drilling steel, use machine oil to cool the drill.

For aluminum, use turpentine or paraffin as a coolant.

When drilling brass, copper or cast iron, do not use coolants. To cool, remove the drill bit from the material frequently to allow it to cool.

EN

Before drilling the actual hole, drill a smaller hole without impact. Drill the actual hole with the impact function turned on. Use carbide impact drills in good condition.

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

Before drilling the actual hole, drill a smaller hole without impact. Drill the actual hole with the impact function turned on. Use carbide-tipped impact drills in good condition.

Drilling in tiles, soft brick, plaster etc.

Use hammer drills. Do not use the hammer function (if available on the drill). Press the tool firmly with a constant force while drilling. Periodically remove the drill bit from the drill hole to remove dust and debris.

Using a tool to insert or remove screws

For this purpose it is recommended to use the lowest possible rotation speed and to use appropriate tips.

The bits can be mounted directly in the drill chuck or using a special magnetic holder.

To unscrew the screw, change the direction of rotation of the switch to left rotation (L).

Using attachments

The tool cannot be used to drive work attachments.

Additional notes

While working, do not exert too much pressure on the material being processed and do not make sudden movements so as not to damage the working tool and the drill.

Take regular breaks while working.

The tool must not be overloaded, the temperature of the external surfaces must never exceed 60 °C.

After finishing work, turn off the drill, remove the battery and perform maintenance and inspection.

MAINTENANCE AND INSPECTIONS

NOTE! Before starting any adjustments, technical service or maintenance, remove the battery from the product socket. After finishing work, check the technical condition of the power tool by visually inspecting it and assessing: the body and handle, operation of the electric switch, patency of the ventilation slots, sparking of the brushes, noise level of bearings and gears, start-up and smooth operation. During the warranty period, the user may not install power tools or replace any components or parts, as this will void the warranty. Any irregularities observed during inspection or during operation are a signal to carry out repairs at a service point. After finishing work, the housing, ventilation slots, switches and covers should be cleaned, for example, with an air jet (with a pressure of no more than 0.3 MPa), a brush or a dry cloth without using chemicals or cleaning fluids. Clean the tools and handles with a dry, clean cloth.
