Warning
It is compulsory to observe the safety instructions included in this manual!
Special designs and versions may differ from the standard models in terms of their technical
details. If any points are unclear, we urgently recommend that you contact DR.BENDER GmbH,
indicating the machine type and machine number.
1.0 General notes
1.1 Symbol- and Pictograph description
This sign tells you rules, if you not pay attention for this your health and the function of
the machine is in danger. You have no warranty if the machine breaks down because
you not looking about this.
1.2 Technical description
BELUGA, ORCA and SQUATINA represent a completely new generation of driving machines used for
stone processing. The highly extensive modular design principle provides the nowadays so important
flexibility in performing cutting operations in concrete and stone. In the process, quite newly developed high
frequency elements are employed in the motor. The frequency range is adjusted within 0 – 1000 Hz by
means of the frequency changer integrated in the Powerbox. At 100 Hz, the rotor reaches a speed of
30,000 min-1. A main advantage results from a weight / performance ratio (motor output = 11 kW / weight =
21.5 kg -> 0.51) so far unequalled with the conventional technology, such as the BBM33extra type (motor
output = 2.4 kW / weight = 13.5 kg -> 0.17). This means that the weight of the machine could be reduced
three times by means of the high frequency technology. Further advantages result from the infinitely
variable speed regulation. Thus, each tool diameter may be assigned its optimum speed, in order to
achieve the best cutting speed possible at the tool. Furthermore, the speed may be continuously reduced in
the process when steel reinforcements appear, thus providing its optimum adaptation to the working
progress. In this case, it is possible to run at much higher cutting speeds (Caution! They depend on the
tool), achieving an up to 150% faster working progress. In the case of conventional machines, the torque
dramatically decreases at high speeds, rendering this advantage impossible.
1.3 Application
The handsaw and the appropriate Powerboxes can be used for the purposes outlined by the data on the
model plate. If you are using special machines, the details in the quotation and order confirmation also
apply.
The driving machines and the Powerboxes are supplied as standard in protection class I, only this can
guarantee the full high quality protection of the FI switch.
If you use suitable saw blades, you will be able to cut in the most diverse material types:
- concrete (even if it contains thick reinforcement steel)
- sandstone and limestone
- all building materials for solid walls
- asphalt carpets
The machine must be
- connected to a duly grounded EEC socket (EEC 5poles, 3P+PE 32A 6h – 400V). No zero
conductor is required.
- operated with a pre-connected all-current failure FI protection or protection insulating transformer
in order to ensure the protection of the operator.

1.4 Safety
Warning
Before using the machine for the first time, check the conformity of the data on
the model plate with the mains voltage and frequency. Voltage deviations of ± 5
% and/or voltage deviations of ± 2 % are permissible. Only adequately qualified
persons, based on their training and experience, may carry out repairs.
The following points are to be given special attention:
- the technical data and details of the permitted use of the machine (commissioning, ambient and
operating conditions) which are set out among others in the catalogue, the operating manual, the
model plate data and the other product information,
- the relevant accident prevention regulations
- the professional use of tools
-the use of personal safety equipment
-not defective and unchanged power boxes correspond to the relevant standards and keep all
demanded limit values concerning EMV (breakdown radiation and noise immunity). Permissible
electromagnetic fields are radiated nevertheless. Electromagnetic fields can disturb the enterprise
of vital electronic devices (e.g. cardiac pacemakers). Carriers of cardiac pacemakers should ask
therefore their physician.
-a professional grounding must be ensured with enterprise at a generator.
-when using within “sensitive ranges” like airports, hospitals or official radio and broadcasting
stations the technical line locally should be informed about the use of frequency-regulated
equipment.
Warning
To use wrong tools or accessories is danger for your life.
2.0 Transport and storage
2.1 Transport
Warning
The driving machines and the powerboxes are to be checked for signs of
transport damage on receipt. Possibly existing damages must be basically
documented in writing.
2.2 Storage
If possible, the storage site should be dry, clean and have a constant temperature. To ensure that the film
of lubricant in the bearings and sealing system is not lost, the motor shaft should be turned through several
revolutions by hand after a lengthy period of storage, for example at monthly intervals. The roller bearings
in the motors should be replaced (or re-greased) if the period between delivery and commissioning is over
four years. If the machines are stored in adverse conditions, this period will be considerably reduced.
