switch automatically to go to the off position and the
indicator disappears;
▪
if, when drilling, the PRCD cuts the power: stop
working, set the main switch of you core drill on the
OFF position and bring your core drill to an
authorized service centre in order to remove the
causes of the electrical dissipation.
ON/OFF switch
Refer to figure 7 in order to identify the on/off switch.
Warning: for your safety, you must get familiar
with the switch in order to understand how you
can switch the machine off in case of emergency.
Checks and precautions
structural damage and damage to the plant
Before starting any drilling activity, talk with the construction
manager or the planner in order to make sure that the drilling
doesn't:
▪
make any damage to the structure of the building
and doesn't change the structural characteristics of
the construction;
▪
damage any water or gas pipeline or any electric
mains.
Checks and precautions to avoid damage
caused by the fall of the core
▪
before drilling, make sure that the possible falling out
of core from the other side of the hole doesn't make
any damage. In any case, bound the area where the
core can fall and signal the danger;
▪
if the possible fall of the core can make damage,
make a system that holds the core when drilling is
completed.
Core bit choice
The maximum and minimum core bit diameter is reported on
the data plate on your core drill motor. Do not use core bit
with different diameter from the one prescribed.
Warning: for your safety do not use different core
bits from the ones prescribed for your specific
application
Warning FOR DRY DRILLING:
Use only laser welded core bits, specifically
manufactured for dry Roto-Percussion drilling.
Normal core bits for wet and dry drilling are not
efficient for dry Roto-Percussion drilling.
The core bit is different depending on the material to be
drilled: consult your dealer about the correct core bit for your
application. The not suited core bit or a core bit not sharp can
overload the motor leading to: damage to the motor, long
drilling time and excessive diamond segments wearing.
Diamond core
replacement
Follow these directions, refer to figure 6:
▪
before mounting or removing the core bit (L) always
unplug the core drill motor;
▪
lubricate the core bit and the core bit spindle threads
in order to make easier, after use, to remove the core
bit;

to avoid
bit mounting
▪ if you your core bit connection doesn't match the
core bit spindle (ex. 1/2 G), use a proper adapter
available among CARDI accessory;
▪
interpose a quick release device (M) between the
core bit spindle and the core bit (as shown in figure
6);
▪
before starting to drill make sure that the core bit is
firmly screwed on the core bit spindle.
Drill stand
Warning: for your safety, make sure that the drill
stand you are using is compatible with the
diameter of the core bit and that it is compatible
with the power of your core drill motor, shown on
the data plate.
manufacturer to fix the machine to the drill stand and to fix the
drill stand to the material you want to drill.
Fastening the work piece and size of the
work piece
▪
if the work object is a block and not part of a
structure, fasten it in order to prevent its movement;
▪
prevent the work piece from shifting, moving or
falling when you are cutting.
Environmental conditions
don't expose the machine to rain, ice or snow;
▪
▪
prevent water or any other liquid from coming into
contact with the electric parts of your machine;
▪
do not use the core drill in explosive atmospheres,
for instance in presence of inflammable liquids, gas
or dust. The electric core drill motor produces sparks
which can ignite dust or smoke.
Overhead drilling (ceiling drilling)
Your CARDI core drill can perform overhead-drilling (upward)
ONLY when DRY drilling.
Your CARDI core drill is not suitable for overhead-drilling
(upward) when WET drilling.
Warning: the possible drop of the core can be
dangerous. Watch out!
Operating instructions
After having followed the instructions given in the previous
paragraph Preliminary operations, follow these operating
instructions:
Warning: do not touch any moving parts of your
and
diamond drill when operating.
▪
if you use the core drill with a stand, fix the stand on
the material to be drilled and then mount the core
drill to the stand, according to the instructions
provided by the manufacturer of the stand. Then
switch on the core drill, keeping the core bit not in
contact with the material to be drilled. After this
operation, using the moving system of the stand,
move the core drill and the rotating core bit closer to
the material and, pressing lightly, drill about 1 cm
into the material. This operation is very important
English
The minimum number of bolts you must use to
fasten your drill motor is written on the Technical
Data sheet.
Follow the instructions given by the stand's
