Attention! In case any suspicious sounds are detected the hammer drill must be immediately disconnected from the mains. Have
it inspected by an authorised service point.
USING THE TOOL
Attention! While operating the hammer drill, it is required to use hearing protection!
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.
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 suffi cient to press the
electric switch.
Drilling in wood
Before drilling, it is recommended to fi x 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 fi x 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 fi rst a smaller guide hole. While drilling steel, cool the drill with machine oil. In case of drilling in aluminium,
use turpentine oil or paraffi n 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.
While the hammer drill is disconnected from the mains, install a drill in the chuck.
If necessary, install the drilling depth-limiting device.
Set the operating mode selector to drilling with hammer action, or if it is available, to drilling without hammer action.
Plug the tool to the mains, turn the hammer drill on with the switch and start work.
During work make regular breaks – avoid overheating of the hammer drill and the tool.
Drilling with hammer action is recommended only in case of compact ceramic materials: concrete, hard bricks, stone etc. In case
of drilling holes of large diameter, it is recommended to drill fi rst a smaller guide hole, and then use a drill of the fi nal diameter. Use
drills designed for hammer action drilling.
It is not recommended to use the hammer action function in case of ceramic materials of loose structure, such as: glaze, soft
bricks, plaster, etc. Hammer action drilling in such materials may damage the material.
The hammer drill is equipped with a clutch that prevents overloading of the electric motor in case when the tool is jammed during
work, for example as a result of hitting a reinforcement wire. In such cases the drill will stop rotating, although the electric motor
is still working.
Also excessive pressure exerted on the tool during work may cause activation of the clutch.
In such cases remove the tool from the hole, make sure the hammer drill is functioning correctly and then resume work, applying
only the pressure which is necessary for proper operation. In case a reinforcement rod or another hidden metal obstacle is hit,
drill it using the hammer action function and a drill for metal of the same diameter as the hammer action drill, and then continue
drilling in the ceramic material.
Drilling in glaze, soft brick, plaster, etc.
Drill as in case of hard materials, 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 with constant strength.
Drilling with the depth delimiter (IV)
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
