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
Core drilling machines may be used in accordance with the data shown on the model plate. The details in
the quotation and order confirmation also apply for the use of special machines.
The core drilling machines generally comply with safety class I, this alone ensures the complete protection
of the RCCB or PRCD.
When using suitable core bits it is possible to drill holes in the most diverse materials:
- Concrete (even with thick reinforcement steel)
- Sandstone and limestone
- All building materials for solid walls
- Asphalt floors
Warning
For manual drilling the machine may only be used for dry drilling as set out in the rele-
vant international regulations. Always use a 110 V isolation transformer and the suit-
able core drilling machine for wet drilling.
For stand-mounted drilling the machine may have the following
- a personnel safety switch (RCCB or PRCD) on the machine itself or
- a coded (1 h) plug, which is connected to the 115 V mains via a safety box (IP44) with an RCCB.
The core drilling machines comply with the regulations of the “Stone and Earth” professional associa-
tion dated July 1989. They are machines of category II, which means that they must be mounted on
stands and stable (pursuant to DIN 57100 and VDE 0100), and the stand must be fitted with the fol-
lowing
- reversing lock
- water extraction device.
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 deviations of ±
5 % and/or voltage deviations of ± 2 % are permissible. Repairs must only be
completed by quality persons who have suitable training and qualifications.
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.
Stand-mounted:
Secure the core drilling machine and the water collection device on the drill stand with a reverse lock. The
drill stand should have high rigidity and precise, low-play guides. Ensure that the core drilling machine axis
is parallel to the drill stand axis.
Insert the core bit and set the speed. Setting instructions are given on page 12.
Connect the water supply. Important: Do not exceed the max. water pressure of 3 bar.
Connect the core drilling machine to the mains via an RCCB box and a code plug 1 h or a PRCD safety
switch.
Manually controlled:
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 = 16 A
Cable length m 7.5 15 25 30 45 60
Cable cross-section mm22.5 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
All core bits with a connection thread of R ½” can be used.
Adapters can be supplied to allow core bits with other connection systems to 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 drill spindle has a right-handed thread.
Always use a 32 mm open-ended spanner to hold against the drill spindle.
Never release the core bit with (hammer) blows since this will damage the core drill.
The core bit can be removed more easily if you apply a little waterproof grease to the drill spindle thread.

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 100 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,
- 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.
- 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.
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.
