English
▪
always wear a dust-mask when performing dry
drilling.
Extension cords
▪
when an extension cord is needed, follow the chart
shown in figure 13 on this manual for the choice of
the right section of the conductors;
▪
the extension cord (made up of cable, plug and
socket) must be suitable for permanent outdoor use
and resistant to oil and grease (like as example
type H07RN-F);
▪
if you use more than one extension cord make sure
that every cable in each extension cord has a
section not lower than the value shown on the chart
in figure 13, considering the total length of the
extension cords;
▪
remember that the more an extension cord is long
the higher the voltage drop is and the worse is the
operation of your core drill. We suggest extensions
no longer than 60 meters.
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.
a)
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 don
’t
use the auxiliary
handle you can lose control of the core drill
and this can lead to serious personal
injuries.
b)
If you use your core drill with a stand, fix the machine
into the collar of the stand (as shown in figure 12).
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.
▪
see figure 8 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.
Integrated dust extraction system
Your core drill is equipped with a dust extraction system
integrated into the machine, shown in figure 3. Follow these
instructions:
▪
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).
As an alternative, you can use a special connection (R).
Checks and precautions to avoid
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. Always 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.
Start drilling device
When you use your core drill hand-held, we recommend to
use a
start drilling device.
Some examples are shown in
figures 9, 10 and 11. 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:
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
core bit mounting and
replacement
Follow these directions, refer to figure 5:
▪
before mounting or dismantling the core bit (L)
always unplug the core drill;
