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
Before connecting the machine, check to ensure that the mains voltage matches
that indicated on the machine rating plate. Always check the PRCD fault current-
safety switch (19) for correct functioning before starting up at the beginning of
each session (see 3.).
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 time. 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 sions 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).
2.3.1. Fitting the diamond core drilling crown
WARNING
Unplug from the mains power supply! Screw the selected diamond core
drilling crown onto the drive spindle (11) of the drive unit, and lightly hand-tighten.
It is an advantage to insert the quick-release ring (art. no. 180015) between
the diamond core drill crown and the drive spindle. There is no need to tighten
it with a wrench. Note that the threads on the drive spindle and diamond core
drilling crown must be clean.
2.3.2. Removing the diamond core drilling crown
WARNING
Unplug from the mains power supply! Use an SW 32 wrench to hold the
drive spindle (11) and an SW 41 wrench to loosen the diamond core drilling
crown (48).
Always unscrew the diamond core drilling crown from the drive unit when the
drilling task is finished. With wet-drilling operations in particular, there is also
a danger of the diamond core drilling crown becoming corroded, making it
difficult to remove.
NOTICE
The casing pipes of the diamond core drilling crown are not hardened. Hitting
(with tools) and impact (during transport) on the casing pipe will lead to damage
that is likely cause the diamond core drilling crown and/or drilling core to become
seized. The diamond core drilling crown may then be rendered unusable.
2.3.3. Sharpening the diamond core drilling crown
REMS diamond core drilling crowns have roof-shaped diamond segments and
do not have to be sharpened in the as-delivered state. At the right thrust pres-
sure and possibly by adding water, the diamond segments sharpen themselves.
Unsuitable thrust pressure as well as dry drilling in concrete leads to the diamond
segments being "polished" and no longer being able to cut. If this occurs, use
the diamond core drilling crown to drill 10 mm to 15 mm into sandstone, asphalt
or a sharpening stone (accessory art. no. 079012) in order to sharpen the
diamond-tipped segments once more.
2.4. Manually-controlled dry boring REMS Picus S1, REMS Picus S3 and REMS
Picus SR
Secure the holder-up (12) to the drill collar (13) of the drive unit.
WARNING
Never carry out manually-controlled drilling without first fitting the holder-
up. DANGER OF ACCIDENTS!
