Warning
Check the compatibility of the voltage and the frequency with the
data on the rating plate prior to use. Repairs must be carried out
only by qualified personnel.
6.1 Dangerousness of the wire saw WB12T
The wire saw system wb12T is equipped with protection devices, however, there is danger
when operating it faultily or misuse it. All persons that are concerned with the set-up, the
initial operation, the handling and maintenance of the system, have to carefully read and
adhere to the following notes.
6.2 Intended use
The wire saw wb12T is built state-of-the-art. If the machine is used in an other than the
intended way, it is dangerous for the user.
The system is suitable only for wire saw works, using wire saws up to Ø 12 mm.
Without the drive unit protective cover (Pict. 2 pos. 1) see p. 16, no cut may be done.
If the air is affected by the cutting process, provide fresh air for the user for his
protection (mainly when dry cutting).
Spare wire lengtsh can be covered by safety guards. However, staying in the
direction of the alignment or in the danger area (Pict. 3, see page 16) during
operation is strictly forbidden.
All used wires must be approved for a cutting speed of 30 m/sec.
Wires may only be used if the following data is known:
oApplicability of use (concrete, masonry, steel, cast iron etc.)
oDimensions
oAllowed cutting speed
oAllowed wire connector (preferent. EDT EURODIMA bwc9 quick wire connector)
Chapped or deformed wires may not be used.
Prior to every use, the diamond wire and the wire connector must be checked for
damages. When defect, the wire resp. the wire connector must be renewed.
Dry and wet cut: The wire saw system wb12 is designed for both dry and wet cuts.
Caution high-voltage current!
Danger to life, when lines are cut or defect!
All system use beyond is classified as not complying with the regulations. For damages
resulting from this misuse, the manufacturer cannot be held liable. The risk is borne by the
user himself.

WB12T

6.3 Danger
Through wire sawing, particles are torn out of the material and the grinding medium with high
speed. Due to the different workpiece forms, it is not possible to fit the safety guard exactly to
the workpiece. Provide appropriate workwear (see personal protection measures). Always
consider the safety safety clearance – the danger area is the idle wire length (Pict. 3, see
page 16).
Fire hazard:
Never cut near flammable substances or in rooms with explosives!
Never cut workpieces from aluminium, magnesium, or any aluminium or magnesium
alloys!
Aluminium and magnesium chipping is readily flammable!
Do not cut any material where harmful dust or vapours are produced in the grinding
process (e.g. asbestos at renovations etc.)!
Do not cut any material where explosive dust is produced in the grinding process!
If above-mentioned work is done, clarify separately which further safety measures are to be
conducted. Your contact is your regulatory authority and your professional association.
6.4 Emissions
The A-rated equivalent continuous sound pressure level of this system is lower than 75 dbA,
thus no ear protection is needed. Hence, this wire saw is especially suitable for the use in
construction of public social institutions such as hospitals and nursing homes.
6.5 Sources of danger
High wire speed
Danger at a potential wire crack, by whipping of the wire and consequenly flying wire
or closure parts, being able to cause heavy chip or crush injuries.
If any limbs come between the wire and the roller guides, they can be pinched or cut
off. Loose clothes can be trapped inbetween the operating wheels, too. Thus,
absolutely avoid the danger area (Pict. 3, see page 16) during machine operation.
Prior to maintenance and cleaning, the motor must be switched off and the voltage
supply must be disconnected (pull out power plug)
Turn off the motor before you leave the machine.
Leave the machine only when it is brought to a halt.
Never remove safety equipment, or never change the system so that the safety
devices do not function anymore.
During the cutting operation, never stay in the alignment of the idle wire (Pict. 3, see
page 16).
Danger through high voltage current – danger to life!

WB12T

6.6 Workplace
The user’s workplace is at the control panel, which is to be placed laterally to the wire saw
unit and out of the danger area (Pict. 3, see page 16).
Caution – never stay in the alignment of the wire level!
6.7 Approved Operators
The system may only be used, maintained and repaired by personnel who know the system
and are aware of the potential dangers. This user manual has to be absolutely adhered to
and should always be available (with a duplicate in the control unit). The operating company
has to provide the manual to the user and make sure that he has read and understood it.
Only then, the user may opeate the system.
Youths under the age of 16 must not operate the wire saw system!
The responsibilities for the different tasks at the unit must be clear and complied with. No
unclarities may occur as they endanger the user’s safety.
The user has to ensure that only authorized personnel operate the machine. He is
responsible towards third parties in the working area of the unit.
6.8 Personal safety measures
Use safety goggles for protection against metal, concrete and masonry chips in the air.
Wear protection gloves against sharp-edged wires and on cut pieces.
Wear tight clothes, no jewellery and put your hair back or cover it.

6.10 Emergency measures
In case of emergency, immediately turn off the system via emergency-stop button at the
control panel.
7 S AFETY E QUIPMENT
Prior to every shift (after interrruption in use), after every maintenance or repair work,
check the safety equipment. Check the specified conditions and position, the secure
fixation, and the required functions.
If there are any defects during operation, immediately stop the unit and eliminate it.
Do not change or remove any safety equipment.
Do not make changes at the machine that disable any safety equipment.
8 M OUNTING THE S YSTEM
8.1 Positioning
Mount the WB12T well with the adjustable feet and position the control unit with a sidewise
long enough distance (Pict. 3, see page 16).
The unit has to be set up on a firm level surface securely and when the underground is flat
and slippery, it has to be fixed with anchor screws, tension belts or bracing rods against any
displacement. The equipment for wire guiding (guiding system 3-wheel or compatible,
existing roller systems) has to be fixed securely onto the workpiece with an achor screw. For
safety reasons and for cutting as precisely as possible, mount them as close to the cut as
possible.
8.2 Electrical connection
According to the connection data at the specification plate of the unit, the electrical
connection is to be conducted with the EN 60204 guidelines.
Check whether the supply voltage complies with the operating voltage given on the
unit.
The connection must be done by a plug connexion with rotary current.
The specific regulations of the local electric power station have to be adhered to. With
a 4-wire network, the standard control panel cannot be used. Therefore, the special
4-wire network has to be utilised. Caution: It is not applicable together with IT
networks (inhouse networks).
Shortly turn on / off the unit at the on / off switch (see p.16, Pict. 13, pos. 1 and 4).
Check the rotational direction of the drive wheel.
At the initial operation, the machine should idle and with motor cooling for 10 min.

WB12T

8.3 Compressed air supply – pneumatic unit
The compressed air supply with 3-parts hose package between the WB12T wire storage and
control panel is to be connected, via two control wires and an air-supply line to the frame of
the saw unit, of air reservoir design.
The pneumatic unit, having only one pneumatic cylinder, is equipped with an optimised belt
guide system. The cylinder is designed with piston rods; there is no moving out over the total
machine dimensions.
The precise feed control ensures constant wear and better tool yield when used correctly.
The new unit reacts much faster so that the wire always is tensioned suitably. In case of wire
clamps, the improved springing effect protects tools and machine.
Due to the modular design, the pneumatic unit can be taken off the sawing system in order to
facilitate transport.
The pneumatic unit is low-maintenance as the settings are adjusted automatically – neither
pre- nor readjustments are necessary. It is soil-resisting due to the extra wiper rings at the
guiding shaft. The pneumatic unit is splash-proof (no high-pressure cleaner!)
Maintenance works:
Greasing the three ball guides weekly
Check the v-belt tension after 300 operating hours
9 I NITIAL OPERATION
Caution: Make sure to secure the construction site! External
persons must not have any access – risk of accident!
9.1 User Manual
Prior to the inital operation, the user manual and the safety instructions must be read
carefully and adhered to. The safety equipment must be checked.
9.2 Turn on/off the machine
Turn on the system:
Tighten the wire with feed pneumatic valve, sset the pressure according to the roller
layout at the pressure regulator and secure feed slide by mounting the stopper (see
p.16, Pict. 13, pos. 1).
Activate the machine: press button EIN (green)
Raise the cutting speed via the potentiometer (max. 30 m/sec)
Turn off machine: press button AUS (see p.16, Pict. 13, pos. 4).

WB12T
12
10 O PERATION
Have you read and understood the safety instructions? You must not operate the
system before.
Mount the safety equipment correctly.
Consider the personal safety measures.
11 M OUNTING THE CUTTING TOOLS
The wires may only be mounted and installed by trained personnel.
Only wires with a diameter of max. 12 mm, that fit onto the rollers, may be used.
When mounting the wire connections, the indicatiosn of the tool manufacturer have to
be considered. The turning of the diamond wire has to be done accordingly.
When using wire fastening sleeves, a new sleeve has to be installed after every cut.
Connecting wire parts with different diameters and the use of wires with loose wire
pearls or with broken carrier wire are prohibited!
Prior to every mounting, a visual examination of the wires must be done to find any
faulty points.
The connectors have to be checked for operational reliability.
Special attention has to be laid on the wire seating solidly on the rollers, and the
swivel roller being attuned to the alignment and then fixed. Only this ensures that the
wire can not skip off the rollers when the unit starts.
With these measures, an optimal function of the wire saw system WB12T can be ensured.
Non-observance risks damages at the wire saw system or the wire.
When a new wire saw unit is put into operation, a 10 min test run at full load should be
done, due to the possibility of transport damages. Only after this test, the unit may be put into
operation.
12 F UNCTIONAL DESCRIPTION
With the wb12, separating cuts in concrete, reinforced concrete, masonry, natural stone, big
metal parts etc. can be conducted. All cuts, whether horizontal, vertical, floor, ceiling, mitre,
diagonal or flush cuts can be done with lowest mounting and operating efforts, with the aid of
suitable wire guiding systems.
The electro pneumatic drive allows the low system weight, low power supply values, highest
electric efficiency, low-noise and smooth running as well as low tool wear. Furthermore, the
wire saw system features highest safety in operation for the personnel due to its
compactness and the protective cover of the whole wire running level within the unit.
In order to further reduce the risk of accidents, the wire is guided through hollow axles, thus,
wire whipping in case of wire crack is not possible anymore.

WB12T
13
Procedure: conducting a wire saw cut
Step 1
Drill the holes for guiding through the wire.
When parts are cut out, the holes should be made bevelled to the cutting direction, as this
facilitates the construction significantly.
Step 2
Drill the holes for fixing the wire guiding device and, possibly, for fixing the unit when the
surface is slippery (see 6.9, p.9).
Step 3
Mind the stable mounting of the unit. Position the control panel sideways to the unit, in a
sufficient distance.
Caution: Never stay in the alignment of the idle wire length.
Step 4
Mind the stable mounting of the wire guiding device at the cut.
Step 5
Guide the wire through all hollow axles (mind the running direction) and through the holes for
the cut. Twist the wire according to the manufacturers specifications, close the connector and
use the required rollers. Slightly tighten the wire with the feed lever and the pressure
regulator at the control panel (1 bar).
Step 6
Align the swivel rollers at the cut and the swivel rollers at the machine (= universal guiding
system) exactly.
Step 7
If the material which is to be cut, has sharp edges, they have to be smoothed off and/or the
wire must be countersunk via the drive wheels manually in mounted and tightened state.
Then, close the guard at the unit.
Step 8
Connect the water supply at the entry spot and at about mid-contact-length of the wire. An
efficient coolant supply heavily affects the cutting as a lack of cooling water leads to the
destruction of the tool.
Step 9
For dry cuts, mount an exhaust device for the cutting dust. The wire cooling is done by long
idle wire lengths out of the cut contact.
Step 10
If possible, idle wire lengths should be covered by safety guards or equivalent materials.
Step 11
When starting up, the pneumatic feed at the control panel must be activated (see p.16, Pict.
13, pos. A). Use less feed pressure to avoid clamping of the wire. Set the start frequency
with the potentiometer and press the “Motor ein” / “motor on” key to start the saw. Start with
low revolution and mind the full occupation of the rollers upon wire initiation.

WB12T
14
Step 12
For wet cuts, run the drive motors revolution up to a wire speed between approx. 20 and
30 m/sec.
Step 13
For dry cuts, choose great wire length and low wire speed.
Step 14
Choose the feed pressure so that there is no overload of the drive motor. The amperemeter
should have a value between 25 and 30 ampere.
Step 15
Examine the wire only when the unit is standing still or the wire speed is very low (2-3
m/sec).
Step 16
When the wire reaches the center of the hollow axe, reposition the swivel rollers of the
guiding device inwards in cutting direction. Thus, the wire is captured at the cut end, and a
damage of the hollow axes is avoided (see Pict. 14, page 24).
Step 17
When the cut is finished, stop the machine with the emergency-stop button (see p.16, Pict.
13, pos. 4). Release feed tension only after the wire comes to a standstill.
13 M AINTENANCE AND SERVICE OF WIRE SAW WB12T
Any maintenance and service works may only be done when the unit stands still. Disconnect
the power supply to the system (put on/off button in 0 position and unplug the mains plug.
The best maintenance activities are the daily removal of mud, dust and dirt.
Discharging condensation water at the wire saw system: with the provided key, open the
drain screw under pressure at the back frame end. Leave open until dry air passes off the
tank. Then lock the valve again.
Always use a hollow axe protection and replace if necessary.
14 M AINTENANCE AND SERVICE OF THE CONTROL PANEL
14.1 Condensation water
In the sight glass of the air regulation valve, condensation water accumulates continuously. It
can be discharged by simple (up-)pressing the hose nipple at the bottom side of the sight
glass. The PVC hose must be connected and the water must be able to drain off to the
outside (see p.16, Pict. 13, pos. F and G).
14.2 Cleaning
Keep the control panel clean and wipe it only with a dry or moist cloth. Never use a water-jet
or high pressure cleaner.

WB12T
15
14.3 Compressor
At a power breakdown, you possibly have to discharge the air at the compressor pressure
switch, as the switch does not allow to release because of the previously built-up pressure.
Open the breather screw manually, release pressure and then turn the screw tight again (see
p.16, Pict. 13, pos. H).
15 L IABILITY AND W ARRANTY
Unauthorized modifications and changes to the machine as well as non-observance of the
operating instructions void the manufacturer's liability for resulting damage.
We only warrant error-free operation for original replacement parts manufactured by
EDT EURODIMA GMBH. Any guarantees and warranty become void if machines or machine
