DRILL SAFETY

DRILL SAFETY WARNINGS

Safety instructions for all operations

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

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!

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 fi rmly 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.

• 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.

OPERATION OF THE TOOL

Right or left rotation

• 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 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 fi rst 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 fi rst 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 condition.
• 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 (VII)

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 fi xed 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 OC.
• Once work has been fi nished, turn the drill off , unplug it from the mains and proceed to maintenance and inspection.
