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
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! 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
fulfilled, 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. REMS Picus drive units
The REMS Picus drive units are universally applicable for both dry and wet
drilling, either manually controlled (Picus S1, Picus S3 and Picus SR) or with
drill upright. The combined drill crown connection of the drive spindle (11) of
REMS Picus S1, Picus S3 and Picus SR allows both the direct mounting of
diamond core drill crowns with internal thread UNC 1¼ and with external thread
G ½. The Picus S1, Picus S3 and Picus SR drive machines are not delivered
with the water feeding device (15) pre-assembled but loose. The adapter for
the water connection on the Picus S1, Picus S3 and Picus SR drive machines
is closed by a cover (14). In this condition the drive machines (Picus S1, Picus
S3 and Picus SR) are used for dry drilling. The water feed device is already
pre-assembled on the REMS Picus 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 REMS Picus S1 is adjusted to a fixed setting. From
a drilling diameter of 62 mm, the REMS Picus 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 REMS Universal diamond core drilling
crown has been modified so that smaller diameters can also be drilled efficiently
with the REMS Picus S1.
The turning speed of the REMS Picus 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 REMS Picus S3. The first 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 first speed.
The turning speed of REMS Picus 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 REMS Picus S2/3,5. The table there shows
gears 1 and 2 in the first 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 REMS Picus 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 outflow. If you cannot engage a particular
speed, turn the handle grip (39) and rotate the drive spindle/diamond core
drilling crown by hand at the same t ime. Pull out the mains plug first!
2.3. Universal diamond core drilling crowns REMS UDKB, REMS UDKB-LS
REMS UDKB – inductively soldered and resolderable
REMS 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 s ions in order to find out which bit should be used.
REMS 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 REMS Universal diamond core drilling crown UNC 1¼ is compat-
ible with the REMS Picus S1, REMS Picus S2/3,5, REMS Picus S3 and REMS
Picus SR and with suitable drive units from other suppliers. If the connection
thread proves to be incompatible with the drive unit, special adapters are avail-
able as accessories (22).
