Read carefully the data reported on the data plate
of your core drill and on the Technical Data sheet
that you will find in the package together with
your product.
In the following text, figures are identified by numbers,
details inside the figures by letters. Figures are depicted on
the first pages of this user manual.
Your core drill motor is suitable to be a part of a diamond
core drill that conforms with the related regulations if the drill
motor is mounted to a proper drill stand fastened by a
proper anchoring system.
Power supply
Earth (Ground)
the metallic parts of you core drill motor are
connected to the earth.
make sure that the socket and possible extension
cords and multiple sockets have the earth
connection and that your electrical system is
properly connected to the earth.
Warning: for your safety, it is important
that the whole system (electrical system,
extension cords, sockets etc.) is connected
to the earth. If you are not sure, ask a
qualified electrician for a check.
Extension cords
when you have to operate with your core drill motor
far from an electrical socket, you can use an
extension cord. If you use it make sure that the
section of the cord is suitable and that the cord is
provided with ground conductor;
the extension cord (made up of cable, plug and
socket) must be suitable for outdoor use. It is better
if the cord is made of rubber and it is H07RN-F;
follow the chart shown in figure 10 on this manual
for the choice of the right section of the conductors;
if you use more than one extension cord make sure
that every cable in every extension cord has a
section not lower than the value shown on the chart
in figure 10, considering the total length of the
extension cords;
remember that the more an extension cord is long
the more the voltage drop is high and the worse is
the operation of your core drill. Don't use extension
cords if you have to operate too far from the
electrical socket.
Preliminary operations
In order to prepare your core drill to operate, follow these
steps. Before proceeding with the preparation make sure
that the plug is disconnected from the electricity network.
follow the instructions given by the
stand manufacturer for fastening the
stand to the material to be drilled;

follow the instructions given by the
stand manufacturer for mounting your
core drill motor to the stand;
Follow these instructions:
if you want to operate in wet mode, connect the
hosepipe to the core drill motor as explained in the
Water insertion paragraph. Make sure that the
water valve is shut;
if your core drill is equipped with a gear change
(figure 2 A), see the data plate on your core drill
motor as shown in figure 6. Identify the right
rotating speed according to the diameter of the core
bit you are using. Select the required gear change
position just when the motor is at standstill;
refer to the following paragraph Diamond core bit
mounting and replacement in order to mount the
core bit to your core drill.
Safety systems
Your core drill motor is equipped with one of the safety
device listed here:
For single phase core drill motors: PRCD (portable
residual current device, assembled on the cord, also
known as GFI)
your core drill motor is equipped with a safety
portable residual current device (PRCD) assembled
on the cord. This device is shown in figure 7;
never use core drill without PRCD;
before starting to work make sure the PRCD works
properly. In order to do so, plug the core drill motor
in and press the green button Reset (M): a red led
will light up (L) showing that electricity is available
to the core drill. Than press the blue button Test (N)
that tests if the device works properly. When you
press it the circuit breaker inside the PRCD should
cut the power off leading the switch automatically to
go to the off position and the red led to go off;
if, when working, the PRCD cuts the power: stop
working, set the switch on OFF position and bring
your core drill to an authorized service centre in
order to remove the causes of the electrical
dissipation.
For twin motors core drill motors: portable electric
safety device box
the core drill motor is equipped with a portable
electric safety device box which includes: one or
more sockets, a residual current circuit breaker and
a special socket into which you can plug your core
drill motor. This device is shown in figure 8;
the box can be plugged into a 5-pin socket with
neutral pin (3 phases + neutral + earth). In this case
you provide the motor with the all power it needs.
Do not plug your core drill motor into a 4 pin socket
(without neutral);
the box can also be connected to a single phase
network using the device R. In this way the
maximum power the motor can have is the
maximum provided by the electric network.
never use your core drill motor without the safety
device box;
before starting to work make sure the box works
properly: connect the box to the electric network,
the led Q should light up, showing electricity inside
the device. Than move the residual current device
switch lever (S) to the on position ("I"). In order to
test the device press the test button (T): the
residual current device (S) should automatically go
to the off position ("0");
