2.0 General instructions
2.1 Technical description
The BELUGA, SQUATINA, KOGIA and the ESPADA represent a whole new generation of drive units for
stone cutting. The exceptionally 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 Powerbox. The Powerbox can be operated on a single-phase 230 V mains supply as
well as on a 400 V mains supply with up to 12 kW. Our motors automatically detect the correct voltage and
then work at the allowed power rating for the voltage. 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 = 8 kW / weight = 12.5 kg
-> 0.64). Using conventional technology e.g. type BBM33extra (motor power output = 2.4 kW / weight =
13.5 kg -> 0.17). This means that the weight of the machine has been reduced fourfold using the high-
frequency technology. 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 opti-
mised according to the progress of the work. Here, you can run the unit at much higher cutting speeds (At-
tention! depends on the tool) and in doing so, the progress of the job can be speeded up by up to 200 %.
With conventional machines, the torque drops very sharply at the higher speeds and therefore, this ad-
vantage does not apply here.
2.2 Applications
All attachments can be used with drive units, which are fitted with the DR. BENDER quick release system.
If you are using custom-built machines, the details on the quotation and the order confirmation also apply.
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
3.0 Transport and storage
3.1 Transport
Warning
The attachments 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. To keep the
lubrication film in the bearings and the seal systems from separating, 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.

5.1 SQUATINA Full blade guard attachment
5.1.1 Saw blade change
Remove the hex screw of the saw flange by turning it
clockwise. Attention, the screw has a left-hand thread.
Remove the top half of the flange with the matching
washer.
Insert the blade into the guard and plug it onto the output
spindle fitting. Always thoroughly grease the saw blade
hole and the output spindle as well as the hex screw.
Place the top half of the flange with the
matching washer onto the saw blade and
make sure that the flange half engages the output
spindle. Attach the hex screw and tighten by turning
anticlockwise. To tighten the hex screw with a SW17
spanner, you must hold the output spindle at the same
time with an SW27 spanner.
5.2 SQUATINA Flush cut blade guard attachment
5.2.1 Saw blade change
Proceed as described above in 5.1.1, but loosen or tighten the 6 hex socket countersunk head screws
instead of the centred left hand thread screw.

5.3 KOGIA attachment
5.3.1 Ring saw blade change / adjustment
1. Remove the ring saw blade from the friction
wheel / clamp.
Fully release the clamping nut (item 39) by
turning anticlockwise in order to remove the ring
saw blade from the friction roller.
To clamp the ring saw blade, the two
clamping nuts must be tightened
equally by turning them clockwise as
far as possible. The spring pressure must be set
so that the rollers automatically reset up to the
depth of wear of the ring saw blade.
2. Unhook / lift the support rollers.
Loosen the hex nut (item 67) with the SW 13
box spanner and tighten it again slightly. Turn
the adjustment sleeve (item 75) approx 8-9 turns
to the left to unhook the support rollers from the
ring saw blade by approx. 2 mm.
When fitting the support rollers, put the
hex nut (item 67) back on slightly.
Using the adjustment sleeve (item 75),
put the roller onto the ring saw blade by turning
it clockwise. The clamping roller may never be
set onto the ring saw blade with too high a
contact pressure. With the ring saw blade
stationary, it must be possible to turn it by hand.
Now tighten the hex nut (item 67).
3. Loosen the front cover
Loosen the 3 raised head screws (item 82 and
item 83) with an SW 4 Allen key. Remove the

4. Replace the friction wheel
Loosen both Allen head screws with the SW 13
Allen key (item 79). To do so, lock the two-hole
spanner (item 95) on the flange to hold it down.
If the friction wheel is worn, it must be
replaced. Only use original spare
parts. Please ask your dealer.
5. Replace the ring saw blade.
The ring saw blade must not be
replated with diamond segments. Only
use original ring saw blades. Please
ask your dealer.
When inserting the ring saw blade,
make sure that the three raised edges
engage into the three grooves of the
ring saw blade.
6. Loosen the support and the guide rollers
Using a swan neck SW 17 box spanner, tighten the
hex washer (item 64 / 45) Loosen both Allen head
screws with the SW 5 Allen key (item 66)
When reinserting the raised head flange
screw, use medium strength Loctite.

7. Replace the support and the guide rollers
Loosen the support rollers (item 63) and the guide
rollers (item 44).
The edges of the rollers that engage the
ring saw blade must be sharp. If this is
not the case, they must be replaced.
5.3.2 Fitting the optional guide plate
Remove the front cover (item 81), see
5.3.1 item 3.
Replace the two distance bushes (item
80) through the complete guide plate
(item 94).

5.4.1 Chain / blade change
Remove the side guard by loosening the two wing screws (1) on the console.
Loosen the hex nut (2) in the centre of the console until it can be turned by hand.
Turn the clamping screw (3) anticlockwise until the blade bears against
the drive wheel.
The old chain can now be removed from the blade tip.
When pulling on the new chain, make sure that the chain is first placed
around the drive wheel, then into the guide groove towards the blade tip.
The blade is now tensioned by turning the clamping screw (3)
clockwise. The chain tension should be set so that the chain is
taut but can still be moved by hand.
Tighten the hex nut (2) again.
The guard can then be pushed on again and fastened with wing screws
(1). Make sure that the plastic washers of the wing screws are not clamped between guard and console.
First remove the chain as described in 5.4.1.
Remove the hex nut (2) completely and pull the holding
plate from the blade.
The blade can now be easily removed from the console.
Place the new blade into the console. Make sure that the
clamping pins (4) are guided into the holes provided on the
blade.
Now insert the holding plate through the oval hole of the blade and insert the hex nut again (2), attach it by
hand.
Move the chain to insert and tension it as described in 5.4.1.
5.5 Saw blades
You can use any saw blade with a connection bore of 1 “ ( 25.4 mm) . Only use saw blades which are
suitable for the stone type. Using only concentric saw blades 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 saw
blade.
