INSTALLATION OF THE ACCESSORIES
ATTENTION! Installation of the accessories must be carried out when the power supply voltage is disconnected. Remove the plug of the cord of the tool from the mains socket!
GB
Installation of auxiliary handle (II)
Affix the clamp of drill chuck to drill body, select the chuck position in such a way as to ensure the safest work. The position of chuck should be selected in such a way, that it could be possible to fully counteract the torque directed opposite to direction of rotation of drill chuck. This torque is generated during normal operation, but the highest value is reached when the drill is chocked in the processed material. Secure the chuck position by tightening the grip handle of auxiliary chuck firmly and reliably.
Installation of drilling depth limiter (III)
Put the limiter bar through the hole in the grip handle of auxiliary chuck. The position of limiter must be secured depending on the type of installation: by tightening the grip handle of the auxiliary chuck, by tightening the knob individually or by means of the lock knob. Detailed method of locking the position of limiter is shown in the illustration.
PREPARATION FOR WORK
Before work may commence, it is necessary to make sure the enclosure and the cord with plug are not damaged. In case any damage is detected, it is prohibited to continue working.
Attention! All actions consisting in installation and replacement of the working tools, installation of guards and guides, adjustments etc. must be carried out when the power supply voltage is disconnected: Remove the plug of the cord of the tool from the mains socket!
Installation of drills in the chuck (IV)
Select a drill with roller grip proper for specific job. Insert the drill bit into the chuck and then holding the back of the chuck rotate the front part of the chuck, so that the drill is fixed in the chuck tightly and reliably.
Adjustments of rotation (V)
Drill is fitted with smooth rotation control. Control is carried out by means of a knob placed on the switch. Rotation mark in form of an arrow, „+” and „-” symbols, or similar symbols, informs to which side the know should be turned to increase or decrease the rotational speed. Rotation of the knob adjusts the range of switch movement, which translates into the value of maximum speed. Gradually pressing the switch we accelerate the rotation of motor.
Setting the direction of the rotation (VI)
Set the rotation switch in accordance with the arrows; right rotation – the arrow pointing to the front of the tool, left rotation – the arrow pointing to the back of the tool.
Attention! The direction of the rotation of the tool may be changed only if the power supply voltage is off!
Activation of the hammer function (VII)
The hammer action operation facilitates drilling in concrete, walls and hard ceramic materials (hard bricks, stones, marble). The hammer action selector must be set to hammer action indicated with a symbol of a hammer.
While drilling in other materials, the hammer action function must be deactivated, setting the selector to the drill symbol.
Preparation for work
Before work:
The processed material must be appropriately fixed, using an anvil or clamps.
Use tools which are appropriate for the task to be realised. Make sure they are sharpened and in good conditions.
Wear working clothes and sight and hearing protection.
Plug the cord to the mains.
Hold the drill with both hands by the handle and the additional handle
Adapt a position that guarantees equilibrium.
Turn the hammer drill off, pressing the switch with a finger.
Attention! In case any suspicious sounds or smell are detected the hammer drill must be immediately disconnected from the mains.
Right rotation should be used while drilling with common right turn drill. Left rotation must be used if the right turn drill is jammed in the material and in case of driving screws.
In case of driving screws into a surface, minimum rotation must be used.
Using the switch lock
It is recommended to use the switch lock in case of long drilling, e.g. in case of drilling in concrete, walls, etc. While the switch
GB
is pressed, press the lock button with your thumb and release the switch. In order to release the lock, it is sufficient to press the electric switch.
Drilling in wood
Before drilling, it is recommended to fix the material to be processed with a clamp or in an anvil, and then using a punch or a nail mark the place of drilling. Install the drill in the chuck, set the speed, connect the drill to the mains and start drilling.
In case of drilling through the material, it is recommended to place a wooden pad under the material, so that the edge of the hole at the outlet will be smooth.
In case of drilling large diameter holes, it is recommended to drill first a smaller guide hole.
Drilling in metals
It is always necessary to fix the material to be processed securely. In case of thin sheet metal, it is recommended to place a piece of wood under it, so as to avoid any deformations. Then mark the places of drilling using a punch and start drilling. Use drills for steel. In case of drilling in white cast iron, it is recommended to use drills with sintered carbide bits. While drilling larger holes, it is recommended to drill first a smaller guide hole. While drilling steel, cool the drill with machine oil. In case of drilling in aluminium, use turpentine oil or paraffin to cool the drill. In case of drilling in brass, copper or cast iron do not use any substances to cool the drill. In order to cool it, is required to remove it frequently from the material.
Drilling in ceramic materials
Drilling in hard and compact materials: concrete, hard bricks, stone, marble etc.)
Before drilling the proper hole, it is recommended to drill first a smaller guide hole with the hammer function off. The proper hole should be drilled with the hammer function on. Use drills with sintered carbide bits in good conditions.
Drilling in glaze, soft brick, plaster, etc.
Drill as described in the point above, but without hammer action.
From time to time remove the drill from the hole, in order to remove dust and debris. While drilling press the tool hard with constant strength.
Using the drill to drive or remove screws
A drill with adjustable rotation and a switch to change the direction of rotation may also be used to drive screws in and remove them. In order to do so, the following is recommended:
- use the lowest rotational speed,
- use appropriate bits.
Bits may be installed directly in the chuck, or with a special magnetic holder.
In order to remove a screw set the direction of rotation to the left (L).
Carving holes
The drill may be used to carve larger holes in wood, using special drills of fixed diameter or interchangeable bits from the saw set – jig-saws. In order to obtain smooth edges of the outlet of the hole, place a piece of wood under the material.
Using attachments
Drills with adjustable direction of rotation should not be used with attachments.
Drilling with the depth delimiter (VIII)
The delimiter can be used to facilitate the drilling of surfaces, where there are performed blind holes, particularly in concrete and wood. Determine the depth of the hole. Install the drill bit in the holder, by using a pen you should mark on the drill bit a distance, from the working drill end which is equal to the depth of the hole. set the depth delimiter so its end would cover the marked the distance „L” on the bit. Make sure, that the delimiter does not move during operation. Start drilling, at a fixed depth the delimiter forehead will rest on the surface around the hole. You should withdraw the drill bit out of the hole.
Additional remarks
During work do not exert excessive pressure on the material to be processed and do not make abrupt movements, so as not to damage the tool and the drill.
Make regular breaks during work.
Avoid overloading the tool.
The temperature of the external surfaces must not exceed 60^ C.
Once work has been fi nished, turn the drill off , unplug it from the mains and proceed to maintenance and inspection.
The declared total value of vibrations has been determined by means of a standard method and it may be used for comparative purposes. The declared total value of vibrations may be applied in the preliminary assessment of exposure.
Attention! The emission of vibrations during work with the tool may differ from the declared value, depending on the use of the tool.
GB
Attention! It is required to determine safety means to protect the operator, which are based on assessment of exposure under real operating conditions (including the whole working cycle, as for example the time when the tool is of or idling, and the time of activation).
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.
