Warning
The safety instructions set out in this operating manual must be followed at all
costs.
Special designs and versions may differ from the standard models in terms of their technical de-
tails. If any points are unclear, we urgently recommend that you contact DR.BENDER GmbH, indi-
cating the machine type and machine number.

2.0 General instructions
2.1 Application
The core drills can be used for the purposes outlined by the data on the model plate. If you are using spe-
cial machines, the details in the quotation and order confirmation also apply.
The core drills are supplied as standard in protection class I, only this can guarantee the full high quality
production of the residual current-operated circuit-breaker or PRCD switch.
If you use suitable core bits, you will be able to drill holes in the most diverse material types:
- Concrete (even if it contains thick reinforcement steel)
- Sandstone and limestone
- All building materials for solid walls
- Asphalt floors
Warning
The core drills comply with the regulations issued by the ”Stone and Earth” Profes-
sional Association issued in July 1989. They are machines of category II, which means
that they must be placed on stands and be stable (pursuant to DIN 57100 or VDE
0100), the stand must be equipped with
- a reversing block, and
- a water suction device.
The machine must be connected to the 230 V mains
- direct using a personal safety switch (residual current-operated circuit-breaker or PRCD), or
- using a coded (1h) plug to a safety box (IP 44) with a residual current-operated circuit-breaker.
2.2 Safety
Warning
Before using the machine for the first time, check that the conformity of the
data on the model plate with the mains voltage and frequency. Voltage devia-
tions of ± 5 % and/or voltage deviations of ± 2 % are permissible. Repairs must
only be completed by quality persons who have suitable training and qualifica-
tions.
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 in the catalogue, the operating manual, the model plate
data and other product information,
- the relevant accident prevention regulations
- the correct use of tools
- the use of personal safety equipment

3.0 Transport and storage
3.1 Transport
Warning
The core drills are to be checked for signs for transport damage on receipt. Any
damage must be documented in writing.
3.2 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 regreased) if the period between delivery and commissioning is over
four years. If the machines are stored in adverse conditions, this period may differ considerably.

5.0 Commissioning
Check that the mains voltage is identical with the voltage specified on the model plate.
When drilling a hole ensure that you are on a secure surface. Make particularly sure the core bit is not bent
during the drilling process and hold the core drilling machine as rigid as possible. Concentrate hard on the
work since if the core bit suddenly blocks, despite the low setting of the safety slip clutch, high forces may
be generated. If you let go of the core drilling during the drilling process, you may suffer serious injury.
Only used three-core extension cables with a protective conductor and an adequate cross-section. If the
cross-section is too low you may suffer excessive power loss and the motor and cable may overheat. An
extension cable must be secured with an overload switch. Recommended cable cross-sections:
Rated current = 9 A
Cable length m 7.5 15 25 30 45 60
Cable cross-section
mm

2.5 2.5 2.5 2.5 2.5 4
When drilling a hole ensure that you have sufficient cooling water. Only use clean tap water, do not use
dirty or waste water. Adjust the supply to the core bit diameter and drive rating of the core drill so that you
do not exceed the rated current.

5.1 Changing gear
Warning
Never change gear using force and only do so when the machine is slowing
down or at a standstill.
Move the gear switch handle by approx. 40° to the next higher or lower gear. If necessary (if it is difficult to
engage the gear) turn the drive spindle briefly by hand until the gear engages easily. Never use tools (pli-
ers, hammer, etc.) to change gear since otherwise gear damage will be inevitable.
5.2 Safety coupling
The values set out in the table are theoretical values and may be used to provide a rough guide for gear
changing. Since a whole range of other parameters also plays a major role in adjusting the speed, we can-
not offer any guarantee if the tool is damaged when using the values in the table. Drilling work for which the
speeds are outside the range of the core drill (values printed in italics), should only be completed with ex-
treme care and by trained personnel.
5.3 Core bits
New core drill bits equipped with the hex polygon connector are already available. Adapters for continued
use of classic core drill bits are also available. Therefore existing equipment can still be used.
Only use core bits that are suitable for the type of stone.
You will keep the core drill in good condition if you only use core bits that are concentric and not deformed
ones.
Ensure that the diamond segments have an adequate undercut against the core bit body.
Warning
To use wrong tools or accessories is danger for your life.
5.4 To change a core bit
The hex polygon connection of the drill spindle allows for toolless assembly and disassembly of the core
drill bit. As soon as the drill bit is positioned on the drill spindle, both hands can be used for tightening the
safety nut on the hex polygon connector. No tools needed anytime.

6.0 Safety instructions
Important
Only use the core drill under supervision. Disconnect the mains plug and check
that the switch has been turned off,
- if you intend to leave the core drill unsupervised,
- for attachment and disconnection work,
- if the voltage drops (below 200 V),
- for adjustments or for fitting an accessory,
Switch off the machine if it stops for any reason. This will prevent its starting suddenly when it is not under
supervision.
Do not use the tool if
-part of the casing is missing or defective,
- If water drips out of the overflow hole, stop work and have the core drill inspected by an authorised
service contractor.
-Only drill above your head with suitable safety equipment (water collector), RCD and transformer
protection class II.
-Connect dust extraction if required.
- After a fault do not switch on the machine again until the core bit can be turned easily.
- Check the area you wish to drill with a line detector to prevent drilling through electric cables, water
or gas lines, etc.
- the switch, lead or plug connector has suffered damage (conduct a visual inspection every day).
-Cooling water must not be allowed to ingress into the motor or the electrical components when op-
erating the core drill in any position.
Do not expose the tool to rain and use not in humidity or wet environment. Use a good lightning. Do not use
the tool near flammable fluids or gase air mixes.
