English
▪
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 fault.
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 outlet.
▪
If you use your core drill hand-held, fix the auxiliary
handle (B) to the core drill, as shown in figure 1.
Warning: If you do not use the auxiliary handle
you can lose control of the core drill and this can
lead to serious personal injuries.
▪
If you use your core drill with a stand, fix the
machine into the collar of the stand (as shown in
figure 11).
Follow the instructions given by the stand's
manufacturer to fix the machine to the drill stand
and to fix the drill stand to the material you want
to drill.
ON/OFF switch
Warning: for your safety, you must get familiar
with the functioning of the switch in order to
prevent unintentional switch-on and to switch-off
the machine quickly, if necessary.
▪
The ON/OFF switch is shown in figure 7;
▪
see figure 9 in order to understand how to use the
switch;
▪
the switch is equipped with a feature (lock-off) that
prevent unintentional switch-on of the core drill.
▪
the switch is equipped with a feature (lock-on) that
locks the switch in the on position;
Warning: the lock-on feature must be used
ONLY when the machine is fixed on a drill stand.
You must not use the lock-on feature when
you are using your core drill hand-held.
Combined dust extraction and water
insertion system
Your core drill can be equipped with a combined dust
extraction and water insertion system integrated into the
machine, shown in figure 3. You can use this system to
insert water or, alternatively, to extract dust using an
industrial vacuum cleaner. The following instructions show
you how to use this system in these two modes.
Warning: do not introduce tools or finger in dust
extraction conduct. In the case that dust conduct
shall be cleaned, before proceeding with the
cleaning, make
disconnected from the mains supply.
Dust extraction
▪
connect a proper vacuum cleaner to the bayonet
coupling pipe adapter (H). The vacuum cleaner
must be suitable to filter thin dust;
▪
connect the bayonet coupling pipe adapter to the
machine (F).
Water insertion
▪
mount the quick hose connector (D) to the
hosepipe, making sure that the valve is shut
(perpendicular to the water stream);

sure the machine
▪
join the connector G to the connector F mounted to
the core drill. Make sure that the two connectors
are firmly joined;
Checks and
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 does not:
▪
make any damage to the structure of the building
and does not 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 does not
make any damage. Always bound the area where
the core can fall and signal the danger;
▪
if the possible fall of the core can make damage,
set up a system that holds the core when drilling is
completed.
Start drilling device
When you use your core drill hand-held, we recommend
using a start drilling device. An example is shown in figure
10. These devices stabylize the core bit allowing safer
drilling conditions.
Core bit choice
The maximum and minimum core bit diameter, according to
the kind of drilling performed, is reported on the data plate
on your core drill. Do not use core bits out of the limits given
for your machine.
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 and the kind of drilling you are performing: consult
your dealer about the correct core bit for your application.
Wrong type of core bit for the application or not sharped
core bit can overload the motor leading to damages to the
motor, long drilling time, excessive diamond segments wear.
Diamond
replacement
is
Follow these directions, refer to figure 5:
▪
before mounting or dismantling the core bit (L)
always unplug the core drill;
▪
lubricate the core bit and the core bit spindle thread
in order to make easier, after use, the core bit
removal;
▪
we recommend interposing a quick release device
(M) between the core bit spindle and the core bit
(as shown in figure 5);
▪
before starting to drill make sure that the core bit is
firmly screwed on the core bit spindle.
