2.0 General instruction
2.1 Technical description
The BELUGA SXC / SXD represent a whole new generation of drive units for stone cutting. The excep-
tionally comprehensive modular system offers the flexibility needed today when performing cutting work in
concrete and stone. To achieve this, newly developed high-frequency motor parts are used in the motor.
The frequency range is controlled by the frequency converter from 0 - 1000 Hz integrated into the Power-
box. At 1000 Hz, the rotor reaches a speed of 30.000 min
-1
. A major benefit lies in the exceptional weight /
power ratio (motor power output = 12 kW / weight = 8.2 kg -> 1.4). Using conventional technology e.g. type
BBM33extra (motor power output = 2.4 kW / weight = 13.5 kg -> 0.17) It means that the weight of the ma-
chine has been reduced sevenfold using the high frequency technology. We have succeeded in running the
Powerbox as well as the drive units on a 230V single phase network or on a 400 V three-phase network.
This means that only one piece of equipment is needed for use on both voltage sources. Further benefits
lie in the stepless speed control. This enables the best speed to be assigned to each tool diameter, in order
to attain the best possible cutting speed on the tool. During work, the speed can be steplessly reduced if
you come up against steel reinforcements and thus can be optimised according to the progress of the work.
Here, you can run the unit at much higher cutting speeds (Attention! depends on the tool) and in doing so,
the progress of the job can be speeded up by up to 150%. With conventional machines, the torque drops
very sharply at the higher speeds. Therefore, this advantage does not apply to conventional machines.
2.2 Applications
The drill motors BELUGA SXC / SXD and the related Powerboxes can be used according to the data
attached to the information plate. When you are using custom-built machines, the details on the quotation
and the order confirmation also apply.
.
The drive units and the Powerboxes are essentially Class I appliances, only this guarantees the full high-
quality protection of the residual current circuit breaker.
When suitable saw blades and drill bits are used, a wide range of materials can be cut:
- Concrete (even with strong reinforcement)
- Sandstone and limestone
- All building materials for solid walls
- Asphalt road surfacing
The machines must be connected to the Powerbox RX/SX 12.

2.3 Safety
Warning
Before commissioning, check that the mains voltage and frequency match the
data given on the information plate. ± 5 % voltage and/or ± 2 % frequency
deviation are permitted. Repairs may only be performed by suitably qualified
staff based on their training and experience.
Pay particular attention to:
-the technical data and information on the permitted use (commissioning, standard operating
conditions), which are included e.g. in the catalogue, the operating manual, the information plate
details, and other product information.
-the relevant accident prevention regulations
-the correct use of tools
-the use of personal protective equipment
3.0 Transport and storage
3.1 Transport
Warning
The drive units must be inspected for transport damage after receipt.
Any damage present must be recorded in writing.
3.2 Storage
The storage location should be dry, clean, and at a constant temperature wherever possible. In order that
the lubrication film in the bearings and the seal systems does not separate, the drive shaft should be turned
several times manually after a lengthy storage period, e.g. at monthly intervals. The roller bearings of the
devices should be replaced (or re-lubricated) if the period between delivery and commissioning is more
than 4 years. This period will be significantly reduced if the storage conditions are unsuitable.

5.0 Commisionning
5.1 Mains connection
Attention
Check whether the mains voltage matches the voltage given on the information
plate. Check whether the mains voltage matches the voltage given on the
information plate.
Remove the protective covers on the plug sockets. These protective covers are designed to protect the
socket against the ingress of water when the plug is not connected. This significantly increases the service
life of the high-quality cable sockets.
Connect the electrical power lead of the Beluga drive unit to the round socket located on the front of the
Powerbox. Lock the bayonet sleeve of the plug socket until you hear it click, in order to maintain the
required IP 67 protection.
5.2 Water connection
The water must first flow through the Powerbox, then through the drive unit, and only then to the drill bit.
Therefore, connect the water supply to the water line (with tap) provided on the Powerbox.
Attention: If possible, do not exceed a maximum water pressure of 3 bar.
The Beluga SX D drive motor is water-cooled. During operation, always supply sufficient cold cooling
water (cooling water should not exceed 30 °C). The machine must be operated during full load operation
with at least 1/2 litre of water per minute. Only use clean tap water, no contaminated or waste water, since
otherwise the heat transfer to the cooling surfaces is no longer guaranteed and the motor may suffer
irreparable damage.
The Powerbox PB RX/SX 12 is normally air-cooled and therefore does not require the water connection.
Water supply fittings (part no. 102122) are available as custom accessories. Please take the necessary
information from the Powerbox PB RX/SX 12 operating manual.

If the Powerbox will be connected to the net, the green LED
flashes. This means that the power box is in standby mode.
When you turn on the green pushbutton, the power box is
switched on. The green LED changes from blinking to a
steady light. With the speed control the speed from 0 to 100%
can be selected. In the operation with the drilling motors, this
value should always be set to 100% to obtain the maximum
speed of the drill spindle.

and the green LED is flashing.
By pressing the Plus + or minus - button you can change the
speed from 0 rpm up to 850 rpm.
By pressing the On-Off switch of the drill motor Beluga SXD /
SXC will now be accelerated to the preset speed.
During the drilling operation can be adjusted at any time-the
rotational speed.
The power display is mirrored by the Powerbox on the control
panel. This is described in detail in the operating instructions
of the Powerbox.

5.4 Drill bits
You can use any drill bit with a connection thread of 1 ¼“ UNC or with a four-hole flange or a six-hole
flange. Only use drill bits that are suitable for the stone type. Using only concentric drill bits that are not
deformed prolongs the service life of the drive unit. Ensure that the diamond segments have an adequate
undercut in relation to the drill bits.
6.0 Safety instructions
Attention
The units must be attended when in use. Disconnect the mains plug and check
that the switch is disabled,
-when the units remain unattended
-during assembly and disassembly
-during voltage drop (rated voltage 400 V 3~ under 340 V), (rated voltage 230 V 1~ under 200 V),
-if the mains voltage fluctuates (phase imbalance) or during interruption of a phase (phase failure),
-when adjusting or fitting an accessory.
Switch the machine off when you stop operation for any reason. This prevents the unit from suddenly
starting while unattended.
Do not use the unit if,
-a part of the housing is missing or defective,
-There is damage to switches, lines, or plug connections (daily inspection!)
-when operating the units, cooling water must not penetrate the electrical components in whichever
location the units are used.
-If water is dripping from the unit, stop work and take the unit to an authorised service centre.
-After a break in operation, only switch on again if the saw blade or drill bit can rotate freely.
-Check the work area with a pipe detector in order to avoid cutting into electrical cables, water pipes
or gas pipes etc.
7.0 Repair and maintenance
Warning
Always disconnect from the mains before starting repair or maintenance work.
After any repair, the unit must be checked by a qualified electrician (legal
requirement pursuant to VBG4 since 1.1.1990).
7.1 Daily maintenance
Check that no water is leaking out of the unit. This may impair the electrical safety of the unit and lead to
damage to the gearbox. In this case, please contact an authorised service centre.
Visual inspection for damage to the switches, the lines, or the plug sockets.
Clean the units after completion of the work.
Check that no water gets into the units during cleaning.
Drain the cooling water after using the machine. (Open the tap and blow out the water using compressed
air). This is particularly important in case of frost formation in winter.

14
7.2 Service after 120 operating hours
A service is due after 120 operating hours. The machine counts the operating hours itself and tells you
when 120 operating hours are reached by a blue LED on the handle. All worn parts are replaced during this
service. The next service is carried out at further intervals of 120 operating hours. The service interval may
be extended by max. 10 %, so you can complete your work with the machine at your own convenience.
If the maximun service interval of 120 + 12 operating hours is exceeded, the warranty becomes null and
void.
7.3 Quarterly
Have the cables, switches, plugs checked by a qualified specialist (provision pursuant to VBG4) and record
this. Replacing the gearbox oil significantly increases the service life of the gearbox.
8.0 Speed setting depending on cutting speed
The drive units of the Beluga series allow stepless speed adjustment. You can thus set the best cutting
speed for your drill bit. This also provides a perfect, quick cut and the service life of the tool is also
significantly extended.
