DRILL SAFETY WARNINGS

Safety instructions for all operations

Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.

EN

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

Brace the tool properly before use. This tool produces a high output torque and without properly bracing the tool during operation, loss of control may occur resulting in personal injury.

Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could 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.

PREPARATION FOR WORK

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 fire 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 effect”, 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 approximately 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 depends 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 to 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 of the batteries

Attention! Before loading, it is required to disconnect the charger charging dock from the mains removing the plug of the charger from the mains socket. Furthermore, it is required to clean the battery and its contacts, removing dirt and dust with a soft and dry cloth.

EN

Disconnect the battery from the tool.

Connect the plug of the charger to the battery socket (II).

Connect the charger to the mains socket.

The diode of the battery will go on, which indicates the beginning of the loading process.

Once the loading process has finished, the diode turn the colour from red to green.

It is required to remove the plug of the charger from the mains socket, and disconnect the plug of the charger from the battery.

Setting the rotational speed and selection of torque

Screwdriver has two mechanically switched gears (III). Depending on the maximum rotational speed you should choose one of them. The gear which is characterized by a lower rotational speed is recommended for tightening and loosening screws, while running the gear with a higher speed is recommended for drilling.

The torque is set with the ring located behind the chuck (IV). The higher the setting number the higher is torque offered by the screwdriver. Do not set a higher torque than it is necessary in order to work properly. Otherwise, this may lead to the destruction of threads. In the case of screwing the screws directly into the material, you should experimentally choose the correct torque, by carrying out a test on waste material. If you do not know which the maximum torque is safe for a given connection, you should set the smallest value and then increase it, until you achieve a suitable value for your work. If the screwdriver reaches the maximum set torque, the overload clutch will start its operation, then you should stop tightening.

If the product has been equipped with a drilling function with stroke, has the hammer symbol is visible on the setting ring. If you adjust the ring on hammer symbol this will start the hammer mechanism. Drilling with stroke should be used for drilling in concrete, and it should not be used for drilling in wood or plastic.

In the case when you use of the tool for drilling holes, you should adjust the ring to the symbol of a drill or a hammer. This will disconnect the overload clutch, and the maximum torque will be transferred to the drill bit.

Attention! You should not use the settings which are marked with numbers for drilling. Operation of the overload clutch during drilling may cause the destruction of material or damage the drill bit, this would also increase the risk of injury.

Mounting the drill bits in the self-locking chuck

You should select the drill which is appropriate for your work with roll drill bit chuck.

Insert the drill bit to the chuck. Hand tighten the chuck, till the drill bit will be firm fixed (V).

Set the maximum torque. The torque knob you should set to the symbol of a drill or hammer.

Adjustment of the direction of rotation

Place the selector of rotation to R – right rotation or L – left rotation (VI).

Attention! The direction of rotation may be changed only if the power supply is off! It is prohibited to change the direction of rotation during operation of the drill and screwer!

Installation of screwdriver bits in the drill chuck

Place a bit holder in the drill chuck and install an adequate bit. (VII)

Preparation for work

Before work:

Secure the material to be processed in an anvil or using woodwork clamps.

Hold the tool with both hands (VIII).

Adopt a stable and secure position.

Turn the tool on pressing the switch with a finger.

Attention! In case suspicious noise, cracks and smell are detected during operation, the tool must be immediately turned off and the battery removed.

USING OF THE TOOL

Attention! Use hearing protection while using the tool!

Using right or left rotation

The right rotation should be used while drilling with common dextrorotatory drill bits.

The left rotation should be used if the dextrorotatory drill bit is seized in the material and to remove bolts. In case of removing bolts, use the lowest rotation.

Drilling in wood

Before making a hole it is recommended to secure the material with clamps or in an anvil, and then to mark the point to be drilled

EN

with a centre punch or a nail. Secure an adequate drill bit in the drill chuck, adjust the torque, connect the tool to the battery and start drilling.

In case of making holes through the material, it is recommended to place a wooden pad under the material, so as to avoid fraying of the edge of the hole.

In case of making holes of large diameters it is recommended to drill first a smaller guiding hole.

Drilling in metals

Always secure the material to be processed. In case of thin sheet it is recommended to place it on a wooden pad so as to avoid undesired bends, etc. Then mark the points to be drilled with a centre punch and start drilling.

Use drill bits for steel. In case drilling is done in white cast iron, it is recommended to use sintered carbide drill bits.

In case of making holes of large diameters it is recommended to drill first a smaller guiding hole.

In case of drilling in steel, cool the drill bit with machine oil.

In case of drilling in aluminium, cool the drill bit with turpentine or paraffin.

In case of drilling in brass, copper or cast iron, do not use cooling agents. In order to cool the drill bit, it should be often removed from the material.

Drilling in ceramic materials

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

Applies only to hammer tools.

Before the desired hole is made, drill a smaller hole with the hammer function off. Drill the proper hole with the hammer function on. Use hammer sintered carbide drill bits in good conditions.

Drilling in glaze, soft bricks, plaster, etc.

Use hammer drill bits. Do not turn the hammer function on (if applicable). During drilling press the tool hard with constant force.

Remove the drill bit from the hole being drilled from time to time, in order to remove dust and waste.

Using the tool to screw bolts in and out

It is recommended to use the lowest rotation and adequate bits.

Bits may be installed directly in the drill chuck or with a special magnetic holder.

In order to unscrew a bolt select the left rotation (L).

Using attachments

The tool must not be used to power working attachments.

Additional information

During work do not exert excessive pressure on the processed material and do not make violent moves, so as to avoid any damage to the working tool and the drill.

Make regular breaks during work.

Do not overstress the tool. The temperature of the external surfaces must not exceed 60°C.

Once the work has been concluded, turn the drill off, remove the battery and carry out maintenance tasks and 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.
