Weighted effective value of acceleration
K = 1.5 m/s²
The indicated weighted effective value of acceleration has been measured against standard test procedures and can be used by way of comparison with another
device. The indicated weighted effective value of acceleration can also be used as a preliminary evaluation of the exposure.
CAUTION CAUTION
The indicated weighted effective value of acceleration can differ during operation from the indicated value, dependent on the manner in which the device is used.
Dependent upon the actual conditions of use (periodic duty) it may be necessary to establish safety precautions for the protection of the operator.

2 Initial startup

2.1 Electrical connection
WARNING
Caution: Mains voltage present! Caution: Mains voltage present! Before connecting the power tool, check Caution: Mains voltage present! Before connecting the power tool, check
whether the voltage given on the rating plate corresponds to the mains voltage.
Only use sockets/extension leads with a functioning protected earth contact.
The function of the PRCD fault current circuit breaker (19)) must be checked
every time before start-up:
1. Plug the mains plug into the socket.
2. Press the RESET button (17), the PRCD control lamp (16) lights red
(operating state).
3. Pull out the mains plug, the PRCD control lamp (16) must go out.
4. Plug the mains plug back into the socket.
5. Press the RESET button (17), the PRCD control lamp (16) lights red
(operating state).
6. Press the TEST button (18), the PRCD control lamp (16) must go out.
7. Press the RESET button (17) again, the PRCD control lamp (16) lights red.
The electric diamond core drilling machine is ready for operation.
WARNING
If the described functions of the PRCD fault current circuit breaker (19) are not
fulfi lled, the device may not be used. There is a danger of electric shock. The
PRCD fault current circuit breaker tests the connected device, not the installa-
tion before the socket nor interconnected extension leads or cable reels.
On building sites, in a wet environment, indoors and outdoors or under similar
installation conditions, only operate the electric diamond core drilling machine
on the mains with a fault current protected switch (FI breaker) which interrupts
the power supply as soon as the leakage current to earth exceeds 30 mA for
200 ms. When using an extension lead, a cable cross section suitable for the
power of the electric diamond core drilling machine must be chosen.
2.2 ROLLER'S Centro drive units
The ROLLER'S Centro drive units are universally applicable for both dry and
wet drilling, either manually controlled (Centro S1, Centro S3 and Centro SR)
or with drill upright. The combined drill crown connection of the drive spindle
(11) of ROLLER'S Centro S1, Centro S3 and Centro SR allows both the direct
mounting of diamond core drill crowns with internal thread UNC 1¼ and with
external thread G ½. The Centro S1, Centro S3 and Centro SR drive machines
are not delivered with the water feeding device (15) pre-assembled but loose.
The adapter for the water connection on the Centro S1, Centro S3 and Centro
SR drive machines is closed by a cover (14). In this condition the drive machines
(Centro S1, Centro S3 and Centro SR) are used for dry drilling. The water feed
device is already pre-assembled on the ROLLER'S Centro S2/3,5. For wet
drilling, see 2.5.
The drive-unit turning speed required for cost-effective core drilling depends
on the diameter of the diamond core drilling crown. Select the turning speed
of the drive unit in such a way that the peripheral speed (cutting speed) of the
diamond core drilling crown runs within a range between 2 and 4 m/s. It is of
course possible to carry out drilling operations outside this optimum range,
albeit subject to reductions in the operating speed and/or service life of the
diamond core drilling crown. Higher peripheral speed apply in masonry.
The turning speed of the ROLLER'S Centro S1 is adjusted to a fi xed setting.
From a drilling diameter of 62 mm, the ROLLER'S Centro S1 operates in
concrete in the optimum peripheral speed range, which always remains inside
acceptable limits when smaller diameters are being handled. The attachment

method used with the diamond-tipped segments of the ROLLER'S Universal
diamond core drilling crown has been modifi ed so that smaller diameters can
also be drilled effi ciently with the ROLLER'S Centro S1.
The turning speed of the ROLLER'S Centro S3 can be selected by means of
a three-speed stepped drive to ensure that in concrete it always operates within
the optimum drilling speed range. The correct speed can be taken from the
machine rating plate (Fig. 7) of the ROLLER'S Centro S3. The fi rst column of
the table shown there covers speeds 1 to 3, the second column shows the
corresponding turning speeds, the third column the core bit diameters for
masonry and the fourth column contains core bit diameters for steel-reinforced
concrete. It shows, for example, that a Ø 102 mm core-drilling operation in
masonry should be carried out in third speed, while drilling into steel-reinforced
concrete requires the use of fi rst speed.
The turning speed of ROLLER'S Centro S2/3,5 can be selected by a 2-step
switching gear so that it always drills in an optimum area. The right gear can
be read from the rating plate (Fig. 8) of ROLLER'S Centro S2/3,5. The table
there shows gears 1 and 2 in the fi rst column and the corresponding speeds
in the second column and the drill crown diameters for masonry and steel-
reinforced concrete in the third column.
The rotation of the ROLLER'S Centro SR can be selected via a 2-gear stepped
drive in combination with a stepless electronic speed regulation to ensure that it
always operates within the optimum drilling range. The correct speed can be
taken from the table (Fig. 9). The correct gear step is selected at the handle grip
(39), the correct rotation via the electronic speed regulation at the dial (57). The
electronic speed regulation keeps the selected speed largely constant also under
load.
WARNING
Wait for the machine to come to a halt before engaging the transmission!
Never try to do this during operation or outfl ow. Pull out the mains plug if a gear
cannot be switched! At the same time, turn the switch handle (39) and move
the drive spindle/diamond core drilling crown by hand.
2.3 Universal diamond core drilling crowns ROLLER'S UDKB,
ROLLER'S UDKB-LS
ROLLER'S UDKB – inductively soldered and resolderable
ROLLER'S UDKB-LS – laser welded and high temperature resistant
The cutting characteristics of the diamond core drilling crown are determined
by the quality of the diamonds, the particle-size and shape of the diamonds,
and also by the bonding agent – the metal powder in which the diamond parti-
cles are set. Users who need to carry out a variety of core-drilling operations
should keep a range of diamond core drilling crowns of different sizes to hand
in order to optimise the cutting process. It is often only possible to ascertain
onsite which diamond core drilling crown is ideal, in terms of cutting performance
(operating speed) and service life, for a particular drilling task. You may even
have to contact the manufacturer of the diamond core drilling crown on various
occa sions in order to fi nd out which bit should be used.
ROLLER has developed the Universal diamond core drilling crown for use in
common drilling operations. These bits are universally applicable for both dry
and wet drilling, either manually-controlled or with drill upright. The connection
thread of the ROLLER'S Universal diamond core drilling crown UNC 1¼ is
compatible with the ROLLER'S Centro S1, ROLLER'S Centro S2/3,5, ROLLER'S
Centro S3 and ROLLER'S Centro SR and with suitable drive units from other
suppliers. If the connection thread proves to be incompatible with the drive unit,
special adapters are available as accessories (22).
