M8x16
Fasten the gearing foot of the
EBM 250/2 RP by means of four M 8
Allen screws to the drill rig.
The drill stand should have a good
stiffness and precise guide ways. The
spindle of the machine needs to go
parallel to the axle of the drill stand.
Use only fall-safe drill rigs.
It is advisable to use a water-collecting
ring.
The EBM 250/2 RP is made in protection class I. In order to protect the
operator, the machine can only be run with a GFCI. For this reason, the
machine is standard equipped with a PRCD switch integrated in the cord
which allows to connect the unit directly with a grounded socket.
!
Attention!
The PRCD-safety switch must not lay in water.
PRCD-safety switch must not be used to switch the tool
on and off.

Before you start working, check the proper functioning by
pressing the TEST button.
Electrical Connection

6
First, check the correspondence of voltage and frequency and compare it
with the data mentioned on the identification plate. Voltage differences
from + 6 % to – 10 % are allowed.
Use only 3-wire extension cable with protecting conductor and a sufficient
cross-section (min. 2.5 mm2). A cross-section which is too small could
lead to excessive power loss and to overheating of machine and cable.
The machine is equipped with a start-up speed limiter to prevent fast
expulsion fuses from unindented responding.
Water Connection
If the drill bit is not cooled enough with water, the diamond segments
could heat up and consequently get damaged and weakened. For this
reason, always make sure that the cooling system is not blocked.
In order to supply the machine with water, please proceed as follows:
Connect the tool to the water supply system or a water pressure vessel
using the GARDENA connector.
Always make sure that the machine only runs with enough clear water
as the seals get damaged when the machine is running dry.
Attention! The maximum water pressure should not exceed 3 bar!
Make sure that the segments are well cooled. If the drilling water is
clear, the segments are well cooled.
Overhead-drilling only with water collection ring.
In case of frost warning, drain the water system.
Changing Gears
The EBM 250/2 RP is equipped with a mechanical 2-speed oil-bath
gearbox.
Select the speed according to the drilling diameter (ref. to the tool's
identification plate).
Use the speed selection to change to the next higher or lower speed until
it locks. Change the speed only when the tool is not running; slightly turn
the working spindle to ease the speed change.
!
Warning!
Never apply force and change the gear only when the
machine is running down.
Never use tools, such as hammers or pliers to change
the gear.

7
Drill Bit Changing
Attention!
The machine is heavy and when you use or sharpen it, it might heat
up enormously. You could burn your hands or get cut or ripped by
the segments. Before the beginning of all works on the tool you have
to disconnect the plug from the mains. Always use protective gloves
when changing the drill bit.
The drill spindle has a right-hand thread.
To hold on spindle always use a jaw wrench SW 32.
Never remove the drill bit with impacts because this way the machine will
be damaged. With some waterproof grease, which is put on the drill bit
thread, and a copper ring between spindle and drill bit you can remove
the drill bit easier.
Drill Bits
Diamond drill bits with an 1 ¼" UNC female thread can be screwed
directly onto the working spindle.
For drill bits with R ½" male thread, adapters are available as accessories.
Always use drill bits which match the material which has to be drilled.
You can prevent the machine from damage if you only use drill bits which
are balanced and not deformed. Pay attention that diamond segments
have enough relief cut towards the drill bit body.
Using the Drilling Unit
In order to operate safely, please observe the following instructions:
Safety at work:
Make sure that your work place is free of anything that might disturb
your work.
Pay attention that your work-place is well-lit.
Make sure that you observe the conditions for the connection with the
power supply.
When laying the cables, make sure that it cannot be damaged by the
tool.
Make sure that you always can overlook the work place in a sufficient
way and that you always can reach all necessary control elements
and safety devices.
In order to avoid accidents, keep other persons away from your work
place.

8
Required space for operation and maintenance
If possible, make sure that you have enough free space for operation and
maintenance around the machine (about 2 metres). This way, you can
work safely and in case of operating trouble you can intervene
immediately.
Preparation
When you drill into blocs, make sure that the blocs are well anchored
and fixed.
Before drilling in supporting parts, make sure that you do not
disregard the statics. Observe the instructions of the experts who are
responsible for the design.
Make sure that you do not damage any gas mains, water mains or
electric cables while drilling.
Pay attention that you do not touch any metallic parts of the machine
when you drill walls and grounds where electric cables could lie
under water.
Pay attention that the drilling core does not hurt anybody or damaging
anything when it drops out.
If the drilling core might cause any damage when it drops out, use an
device that can hold back the drilling core.
Make sure that the drill bit is well fixed.
Only use tools which are suitable for the particular material.
Fastening of the Drill Rig
The diamond core drill EBM 250/2 RP may only be used mounted on a
drill rig. Since the drill rig is not included in the delivery, we point out some
important kinds of assembly.
For this purpose, please refer to the drill rig’s operating instructions.
Vacuum fastening:
Re. vacuum fastening, make sure that you have a sufficient vacuum
(minimum -0.8 bar). Make sure that the gaskets are not worn.
Attention! Do not use the vacuum fastening on the wall or overhead!
Do not forget that the levelling screw may be turned out only up to a
certain extend in order not to destroy the vacuum.
Dowel fastening:
The most common way of fastening is dowel fixing.
If possible, use metal dowels only. The dowel diameter must not be
smaller than 12 mm.
In order to fasten the drilling unit correctly, you need the fastening set
(order number 35720000).
Drill a hole with a diameter of 16 mm, 50 mm deep. Make sure that
the hole is free of dust.

9
Insert a dowel and open it with an expanding mandrel.
Screw the thread rod into the dowel.
Put the drilling unit with the deep hole in the base onto the thread rod.
Place the washer and screw the butterfly nut very tightly.
Adjust the drilling unit in the platform by using the four screws.
Drilling
Vertical drilling
Switch the PRCD on.
Open the water supply.
Switch the motor on without touching the surface with the drill bit.
Turn the handle to bring down the drill bit until it contacts the surface.
In order to reach an exact centring of the drill bit, keep the feed low
for the first centimeter of cutting depth.
Then you can drill faster. A too small drilling speed reduces the
power. On the other hand, when the drilling speed is too high, the
diamond segments quickly become blunt.
Angular drilling
Remove the screw in the foot base which arrests the column at 90°.
Loosen the two screws on the base of the column and turn the
column to the requested angle.
Retighten the screws again.
At the beginning, it is better to drill very slowy because the bit only
meshes with a fraction of its cutting area with the material. If you drill
too fast or with a pressure which is too high, the bit can be off centre.
You have hit reinforced iron when you recognise while drilling that the feed
rate gets very low, when you need to use more force, or when the water
leaking from the bore hole clearly shows some metal chips.
Reduce the pressure on the drill bit to cut through the reinforced iron
without any problems. You increase the pressure again when you have cut
through the reinforced iron.
Drill bit extension
If you have to drill deeper than the usable length of your drill bit is:
First, only drill to the point the usable length of the bit reaches.
Remove the bit and pull the centre core out of the hole without
moving the core drilling unit.
Push the drill bit back into the bore hole.
Screw an adequate extension between drill bit and motor. If the collet of
the drill bit is 1 ¼”, please do not forget the copper rings which make the
removal of the drill bit easier.

10
Overload Protection
In order to protect the operator, motor and drill bit, the EBM 250/2 RP is
equipped with a mechanical and electronic overload protection.
Mechanical: In the event of a sudden jamming of the drill bit, the
machine's kickback is limited to a reaction torque
controllable by the operator by means of a slip clutch.
Electronic: In case of overload due to large a feed force, the electronic
facility in the tool switch will deenergize the tool. After
discharge and reengagement one can drill again.
Safety Clutch
The safety clutch should absorb shock and excessive stress. It is an aid
and not an absolute protection. Therefore, you have to handle and drill
carefully. To keep it in good condition, the clutch should slip for a very
short time (max. 2 seconds) in each case only. After excessive wearing
the clutch has to be renewed by an authorized service shop.
Fracture of Segments
If a diamond segment, parts of the reinforcement or something similar
breaks out, and consequently the drill bit seizes, stop working on this bore
and drill a hole with the same centre and a diameter being 15 – 20 mm
bigger.
Do not try to finish your work using another drill bit of the same
diameter!
Drill Bits
Diamond drill bits with a 1 ¼" UNC female thread can be screwed directly
onto the working spindle.
For drill bits with R ½" male thread, adapters are available as accessories.
Always use drill bits which match the material which has to be drilled.
You can prevent the machine from damage if you only use drill bits which
are balanced and not deformed. Pay attention that diamond segments
have enough relief cut towards the drill bit body.
After Drilling
When you have finished drilling:
Pull the drill bit out of the hole.
Stop the motor by using the motor switch and not the PRCD switch.

11
Close the water supply.
Removal of the core when it sticks in the drill bit:
Separate the drill bit from the motor.
Put the drill bit in a vertical position.
Knock carefully on the pipe by using a wooden hammer shank till the
drilling core slips out. Never throw the drill bit against a wall by force
or set about it with tools, such as hammer or jaw wrench. Otherwise,
the pipe could go out of shape and neither the core can be removed
nor the drill bit reused.
Removal of the core from blind holes:
Break off the core with a cotter or lever, or in pieces. Lift the core out with
appropriate tongs or drill a hole in the core, screw an eyebolt in and pull
the core out.
Care and Maintenance
Before the beginning of the maintenance or repair works you
have to disconnect the plug from the mains!
Repairs may be executed only by appropriately qualified and experienced
personnel. After every repair the machine has to be inspected by an electric
specialist. Due to its design, the machine needs a minimum of care and
maintenance. Regularly the following works have to be carried out or rather
the component parts have to be inspected.
Clean the drilling unit after having finished drilling. Later on, you have
to grease the spindle thread. The ventilation slots always have to be
clean and open. Pay attention that no water gets inside the core drill
during the cleaning process.
After the first 150 hours of operation you have to replace the gearbox
oil. Gearbox oil changes bring about an essential increase of the
tool’s lifetime.
After approximately 250 hours of operation the carbon brushes have
to be checked by a specialist and if necessary removed (only use
original carbon brushes).
Have switch, cable and plug checked by an electric specialist
quarterly.
Our after-sales service responds to your questions concerning maintenance
and repair of your product as well as spare parts.
EIBENSTOCK’s application service team will gladly answer questions
concerning our products and their accessories.

Environmental Protection
Raw material recycling instead of waste disposal
In order to avoid damages on transportation, the power tool has to be
delivered in sturdy packing. The packing as well as the tool and its
accessories are made of recyclable materials and can be disposed
accordingly.
The tool’s plastic components are marked according to their material,
which makes it possible to remove environmental friendly and
differentiated because of available collection facilities.
Only for EU countries
Do not dispose of electric tools together with household
waste material!
In observance of European Directive 2012/19/EU on waste
electrical and electronic equipment and its implementation
in accordance with national law, electric tools that have
reached the end of their life must be collected separately
and returned to an environmentally compatible recycling
facility.
Noise Emission / Vibration
The indication of noise emission is measured according to EN 62841-3-6.
The level of acoustic pressure on the work place could exceed 85 dB (A); in
this case protection measures must be taken.
Wear ear protectors!
In order to protect the motor, this power tool is equipped with auto-stop
brushes. When the carbon brushes are worn out, the machine switches
itself off. In this case both brushes must be replaced at the same time with
original brushes by an electrical specialist.

Sikkerhedsinstruktioner
Det er kun muligt at arbejde sikkert med apparatet, hvis
du læser hele brugsanvisningen og nøje følger
instruktionerne deri.
Desuden skal de generelle sikkerhedsanvisninger i det
vedlagte hæfte følges. Få en praktisk instruktion før
første brug. Opbevar alle sikkerhedsoplysninger og
instruktioner til senere brug.
Hvis tilslutningskablet bliver beskadiget eller skåret over
under arbejdet, må du ikke røre ved det, men skal straks
trække stikket ud af stikkontakten. Brug aldrig apparatet
med et beskadiget tilslutningskabel.
Før der bores i lofter og vægge, skal borestedet
kontrolleres for skjulte el-, gas- og vandrør.
Kontrollér arbejdsområdet, f.eks. med en metaldetektor.
Kontakt den ansvarlige bygningsingeniør, før arbejdet
påbegyndes, for at fastslå borehullets nøjagtige
placering.
Når du borer gennem lofter, skal du sikre området
nedefra, da borekernen kan falde ud i bunden.
Sørg for, at maskinen ikke udsættes for direkte regn.
Arbejd ikke i potentielt eksplosive atmosfærer.
Arbejd ikke på stiger.
Asbestholdige materialer må ikke forarbejdes.
Bær aldrig apparatet i kablet, og kontroller apparatet, kablet og stikket
før hver brug. Få kun skader repareret af en fagmand. Sæt kun stikket i
stikkontakten, når maskinen er slukket.
Manipulation af enheden er ikke tilladt.
Kerneboremaskinen må kun betjenes under opsyn. Træk netstikket ud,
og kontroller, at kontakten er slukket, hvis kerneboremaskinen
efterlades uden opsyn, under monterings- og demonteringsarbejde, ved
spændingsfald, ved isætning eller montering af tilbehør.
Sluk for maskinen, hvis den stopper af en eller anden grund. Det
forhindrer maskinen i at starte pludseligt, når den er uden opsyn.
Brug ikke apparatet, hvis nogen del af kabinettet er defekt, eller hvis
kontakten, forsyningskablet eller stikket er beskadiget.
Elværktøj skal inspiceres visuelt af en specialist med jævne mellemrum.
Før altid kablet bagud væk fra maskinen.
Når kerneboremaskinen er i drift, må der ikke trænge kølevand ind
i motoren og de elektriske komponenter i nogen af
brugsstillingerne.

18
Udfør kun boring over hovedhøjde med passende
beskyttelsesforanstaltninger (vandopsamlingsanordning).
Hvis der lækker vand fra overløbshullet på gearkassehalsen, skal du
stoppe arbejdet og få kerneboremaskinen repareret på et autoriseret
specialværksted.
Når du har afbrudt dit arbejde, må du først tænde for
kerneboremaskinen, når du har sikret dig, at borekronen kan rotere frit.
Ræk ikke ind i roterende dele.
Personer under 16 år må ikke bruge apparatet.
Brugeren og personer i nærheden skal bære egnede sikkerhedsbriller,
hjelm, høreværn, beskyttelseshandsker og sikkerhedssko, når

er udstyret med præcise føringer.
Sørg for, at maskinens akse er parallel med
boreriggens søjle.
Brug kun borestativer med tilstrækkelig
stabilitet.
Det anbefales at bruge en
vandopsamlingsring.
Elektrisk tilslutning
EBM 250/2 RP er konstrueret i beskyttelsesklasse I. For at beskytte
operatøren må maskinen kun betjenes via en fejlstrømsafbryder og leveres
derfor som standard med en PRCD-afbryder integreret i kablet til brug på
en stikkontakt med jordkontakt.

19
!
Giv agt!
PRCD-afbryderen må ikke nedsænkes i vand.
Brug ikke PRCD-strømafbrydere til at tænde og slukke for
maskinen.
Før arbejdet påbegyndes, skal du kontrollere, at det
fungerer korrekt ved at trykke på TEST
-
knappen.
Før ibrugtagning skal du kontrollere, at netspændingen og frekvensen
svarer til de data, der er angivet på typeskiltet.
Spændingsafvigelser på + 6 % til - 10 % er tilladte.
Brug kun et 3-ledet forlængerkabel med en beskyttende jordleder og et
tilstrækkeligt tværsnit (min. 2,5 mm²). Et utilstrækkeligt tværsnit kan føre til
for stort strømtab og overophedning af maskinen og kablet.
Vandtilslutning
Hvis borekronen ikke køles tilstrækkeligt med vand, kan
diamantsegmenterne blive varme, så de beskadiges og svækkes. Du skal
derfor altid sørge for, at kølesystemet ikke er blokeret.
Gå frem som følger for at forsyne boret med vand:
Tilslut maskinen til vandforsyningen eller en vandbeholder under tryk
ved hjælp af GARDENA-stikproppen.
Brug kun maskinen med rent vand og tilstrækkelig vandforsyning, da
tør drift vil beskadige tætningerne.
Forsigtig! Det maksimale vandtryk må ikke overstige 3 bar!
Sørg for, at segmenterne er tilstrækkeligt afkølede. Hvis borevandet er
klart, er afkølingen tilstrækkelig.
Luk det hul, du lige har boret, hvis du vil gøre det større for at opnå en
tilstrækkelig tilførsel af kølevand.
Brug altid en vandopsamlingsring, når du arbejder over hovedet.
Tøm vandsystemet, hvis der er risiko for frost.
Skift af gear
EBM 250/2 P har en mekanisk 2-trins oliebadsgearkasse.
Juster maskinens hastighed til borediameteren (for detaljer, se enhedens
parametre). Drej gearkontakten til det hurtigere eller langsommere gear.
Hastighedsændringen bør kun udføres, når maskinen står stille; understøt
om nødvendigt skifteprocessen ved at dreje arbejdsspindlen en smule.

20
!
Advarsel!
Brug aldrig magt, og skift kun, når maskinen kører i frigear
eller står stille!
Brug ikke værktøj som tænger eller hammere til at skifte!
Kernebits
Diamantborekroner med et indvendigt gevind på 1¼" UNC kan skrues
direkte på arbejdsspindlen.
Adaptere fås som tilbehør til borekroner med et R ½" udvendigt gevind.
Brug kun borekroner, der er beregnet til det materiale, der skal bores i. Du
beskytter kerneboremaskinen, hvis du kun bruger koncentriske og ikke-
deformerede borekroner.
Sørg for, at diamantsegmenterne har tilstrækkelig afstand til borekronens
krop.
Udskiftning af borekroner
Forsigtig!
Værktøjet er tungt og kan blive varmt, når det bruges eller slibes. Du
kan brænde dine hænder, skære, rive eller knuse dig selv på
segmenterne.
Brug derfor altid beskyttelseshandsker, når du skifter værktøj.
Borespindlen har et højregevind.
Brug altid en gaffelnøgle SW 32 som modhold, der er fastgjort til
borespindlen.
Løsn aldrig borekronen med (hammer)slag, da det vil beskadige
kerneboremaskinen.
Lidt vandfast fedt på borespindelens gevind og en kobberring mellem
spindlen og boret gør det lettere at løsne boret.
Betjening af boreenheden
For at betjene maskinen sikkert skal du overholde følgende
instruktioner:
Detaljer om placeringen
Ryd arbejdsstedet for alt, der kan hindre arbejdsprocessen.
Sørg for tilstrækkelig belysning på brugsstedet.
