network and have it inspected by an authorised service centre.
LEDs
The tool has LEDs signalling the condition of the carbon brushes in the motor and assisting in detecting any damage to the power
cord. The LED marked with the plug symbol lights up immediately after plugging the plug into the mains socket. If the LED does
not light up, after connecting the plug to the mains, it may indicate lack of power supply in the socket or a faulty power cord. Do
not attempt to repair a damaged power cord, but change it to a new one. Have the power cord changed at an authorised service
centre.
If the LED marked with the carbon brush symbol lights up, the carbon brushes in the motor must be changed. Have them changed
at an authorised service centre. Working with worn-out carbon brushes can damage the motor and cause electrical shorts leading
to a fi re and/or electric shock.
USING THE TOOL
Attention! While operating the hammer drill, it is required to use hearing protection!
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.
Hammering
While the tool is disconnected from the mains install the required tool in the chuck: cutter or punch.
Set the operating mode selector to the hammering position. Plug the drill to the mains, turn the hammer drill on with the switch,
wait until it has reached the full speed and start work.
During hammering, do not drive the tool too much into the material to be processed. Hack the material off in thin layers, not exert-
ing excessive pressure on the hammer drill.
Using attachments
Drills with adjustable direction of rotation should not be used with attachments.
Protection of the drilling chuck
If the hammer drill is equipped with a rubber protection of the chuck, then it is recommended to use it in case of drilling with the
drill pointing up, e.g. for drilling in ceilings. Once the drill has been installed in the chuck, place the protection on it. Dust and debris
generated during drilling will accumulate in the protection, which permits to keep the chuck clean. Once work has ended, remove
the protection from the drill, remove dust and debris from the protection, and then rinse it under lukewarm water.
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 sur-
faces must not exceed 60
O
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 diff er from the declared value, depending on the use of the tool.
