English
▪
lubricate the core bit and the core bit spindle thread
in order to make easier, after use, the core bit
removal;
▪
we recommend to interpose 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.
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 produces sparks
which can ignite dust or smoke.
Overhead drilling (ceiling drilling)
Your CARDI core drill can perform overhead-drilling
(upward).
Warning:
the possible drop of the core can be
dangerous. Watch out!
Operating Instructions
Follow these instructions:
Warning:
do not touch any moving parts of
your diamond drill when operating.
▪
if you use the core drill hand-held, using a start
drilling device, begin to drill into the material,
pressing lightly. Let the diamond segments drill
about 1 cm deep into the material. This operation is
very important because, if correctly carried out,
leads to a perfect centering and makes drilling
easier. After this some start drilling devices need to
be removed. Perform this starting phase in
“Rotative mode”.
▪
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
because, if correctly carried out, leads to a perfect
centering and makes drilling easier. In any case,
refer to instructions provided by the manufacturer of
the stand.
Perform this starting phase in “Rotative
mode”.
▪
at this point you can choose if continue to drill in
“Rotative mode” or if putting the machine in “Roto
-
Percussion mode” to m
ake the job. Refer to the
Paragrah
“Rotative and Roto
-Percussion modes
”.
▪
after the centering operation, increase the forward
speed. On one hand, a too low forward speed leads
to polishing of diamond sectors, decreasing their
drilling capacity. On the other hand, a too high
forward speed, leads to a quick segments wear.
▪
when drilling, make sure that the rotation axis of the
core bit doesn’t move and avoid any possible
movement of it. When the core bit rotation axis
moves, the friction between the wall of the hole and
the core bit
’s metal body
leads to a considerable
power loss.
▪
If, for any reason, you can not continue drilling, you
can make a new hole around the old one (over-
drilling), keeping the same rotation axis. The
diameter of the new hole must be at least 15-20
mm bigger than the diameter of the old one;
▪
drilling materials containing wood, cork, rubber,
foam polystyrene can generate problems to the
drilling to continue. If you have this kind of
problems, pull the core out of the hole and remove
all the
materials listed before that don’t allow the
core bit to go on and then continue with drilling
operations;
Warning
: in case the electric power goes off,
set the switch to the off position, preventing the
machine from accidentally self starting.
Warning:
do not touch the core bit after
performing a drill. The core bit can be very hot
and cause severe burns.
Mechanical clutch
Warning:
the unexpected block of the core bit
rotation can cause an heavy tear at your arms.
The maximum force of this tear at your arms, accordingly
with the safety regulation, can not exceed 40 Kg. Be always
ready to resist this kind of force and to quickly release the
switch.
Your CARDI core drill is equipped with a safety mechanical
clutch that comes into operation in case of sudden stop of
the core bit rotation. The block of the core bit rotation could
be dangerous for the operator so, despite your drill is
equipped with this device, you must always be watchful and
be ready to resist the tear and release the switch to off
position.
Multifunction electronic
▪
the soft-start (peaks limiter) allows the motor to not
start at full power, reduces current peaks that
occurs when you switch the motor on, helps you
when you begin drilling, allowing gradual core bit
rotation and avoiding tears at your arm, and allows
you to use your core drill connected to the
household electric supply equipped with automatic
circuit breaker;
▪
the electronic clutch cuts off power to the motor in
case of excessive overload, increasing the operator
safety and preventing damage to the motor. When
the overload is over, the device gives back power to
the motor that begins working again;
▪
if the electronic clutch operates frequently means
that the core drill is not used properly. Possible
causes can be a not suitable forward speed, an
