PRODUCT USE
Using the right-hand or left-hand rotation direction
Use right-hand rotation when drilling with commonly used right-hand drill bits.
Use left-hand rotation if the right-hand drill bit is jammed in the material.
Drilling in wood
Before making a hole, it is recommended to fi x the workpiece with G clamps or in a vice, and then use a punch or a nail to de-
termine the place of drilling. Attach the correct drill bit to the chuck, set the speed, connect the drilling machine to the mains and
start drilling.
When making through holes, it is recommended to place a wooden pad under the material, so that the edge of the hole at the
outlet will not be torn.
In the case of drilling holes with large diameters, it is recommended to drill a smaller guide hole beforehand.
Drilling in metals
Always fasten the workpiece securely.
In the case of a thin sheet, it is recommended to place a piece of wood under it to avoid unwanted bends, etc. Then mark the
locations of holes with a punch and start drilling. Use drill bits intended for steel. It is recommended to use sintered carbide drill
bits when drilling in white cast iron. When drilling larger holes, it is recommended to make a smaller guide hole beforehand. When
drilling in steel, use general purpose lubricating oil to cool the drill bit. For aluminium, use turpentine or paraffi n as a coolant.
Do not use cooling agents when drilling in brass, copper or cast iron. For cooling, remove the drill bit from the material frequently
to allow it to cool down.
Drilling in ceramic materials
Drilling in hard and compact materials (concrete, hard brick, stone, marble, etc.)
Drill a smaller hole without impact before drilling the actual hole. Drill the actual hole with the hammer drilling function engaged.
Use sintered carbide percussion drill bits in good condition.
Drilling in glazed tiling, soft brick, plaster, etc.
Drill as mentioned above without impact.
Remove the drill bit from the drilled hole from time to time to remove dust and waste. During drilling, press the tool fi rmly with
constant force.
When drilling in the position in which the rotary hammer is facing upwards, it is recommended to use the tool chuck guard (avail-
able separately), which will prevent dust generated during work from entering the chuck. The guard is made of fl exible plastic and
has a hole through which the drill bit should fi tted in the chuck.
Using the rotary hammer to screw or unscrew screws
It is not recommended to use the rotary hammer for screwing and unscrewing screws. Typical bits with a hexagon holder cannot
be fi tted directly into the power tool's chuck. It is possible to use a self-centring tool chuck equipped with a SDS Plus pin for this
purpose, but changing the centre of gravity of the entire tool can make driving screws unergonomic. The tool also does not allow
for setting the maximum torque, which can result in over- or under-tightening.
Cutting holes
The rotary hammer can be used to make larger holes in the wood with special fi xed diameter drill bits or interchangeable bits from
a set of saws/hole cutters for holes. In order to avoid burrs and jagged edges at the outlet of the made hole, it is recommended to
place a waste piece of wood under it.
Cutting holes in wood must be carried out with the hammering function turned off .
Using attachments
Tools with variable rotation direction should not be used to drive the working attachments.
Illuminating light
The tool has a light to illuminate the work area. The light is turned on after pressing the power switch and turns off after the power
switch is released.
Additional notes
When working, do not exert too much pressure on the workpiece and do not make sudden movements in order not to damage
the bit and the product.
Take regular breaks during work.
Do not overload the tool, the temperature of the external surfaces must never exceed 60°C.
