Warning: for your safety, make always sure
that the material in which you install the anchor
and the anchor itself are suitable to hold the
system when drilling. Sometimes you may need
more than one anchor. In any case the anchor's
thread must be at least M12.
Read the instructions provided by the anchor
manufacturer and make sure that the anchor is
suitable for this use.
Follow these instructions:
once decided the position of the hole, identify the
▪
position of the anchor. The closer the anchor is
to the column, the better the fastening is;
choose a proper anchor for the specific
▪
application making sure that the thread is at least
M12;
▪
make a suitable hole for the anchor and insert it
into the hole. Then, tighten a proper threaded bar
to the anchor;
position the stand over the anchor inserting the
▪
bar (figure 3 I) into the slot (H) on the base. Put
the washer (included in the package with your
stand) over the bar and tighten securely the nut
(see figure 3). Make sure that the washer is
securely engaged with the base.
if needed, turn the L screws in order to adjust the
▪
base.
Proper anchors are available among CARDI accessories.
Additional fastening with a adjustable prop
After having fixed the stand with an anchor, when possible,
the use of a prop is highly recommended. This is a very
effective method to further stabilizing the stand. It consists in
applying the specific designed accessory (figure 8),
connecting it to the upper extremity of the column as shown
in figure 9.
This method do not take the place of the anchor, but must
be used together with it.
It can be applied only when, in front of the hole to be
performed, there is a sufficiently solid wall. For this reason,
this is a method easily to employ inside buildings.
An example of using the adjustable prop accessory is shown
in figure 9.
Overhead upward drilling
Warning: overhead upward drilling with electric
motors not protected against the ingress of water,
is allowed only in dry mode. Overhead upward
drilling with the use of water can provoke
electrocution.
Fix the base of the stand to the floor with an anchor. Mount
the adjustable prop accessory on the top of the stand (figure
9). The accessory must be placed between the top of the
stand and the surface to be drilled (e.g. the ceiling). The core
drill motor must be connected to the carriage on the
adjustable prop accessory. Make sure that the footing
surface is able to support, besides the feeding force, also the
system (stand, drill motor, core bit), the weight of the water
inside the core bit and the core (when finish drilling).
Feed handle
The drilling process generates a considerable level of
vibration on the feed handle and consequently to the hand of
the operator. Your stand is therefore equipped with a special
feed handle that feature a vibration reduction device. It
provides a substantial reduction of the level of vibration
transmitted to the hand.
The feed handle has a central slider (U), that activates and
deactivates the anti-vibration function:
▪
to activate the anti-vibration function, pull the slider
toward yourself (figure 6b)
▪
to deactivate the anti-vibration function, push the
slider into the handle (figure 6a)
Figure 4 shows how to mount the handle to the carriage shaft
(Q). You can mount the handle to the left or to the right side
of the carriage. Some models can be equipped with a feed
system that powers the travel of the carriage.
Locking the carriage
The carriage is equipped with a locking system (figure 5).
The carriage must be locked when you mount the core drill
motor, when you mount or replace the core bit or when you
transport the stand.
Drill bit aligner
The drill bit aligner feature allows to guide the core bit during
the starting of the hole. It helps to avoid core bit vibrations.
Proceed as follow:
unscrew the lock devices (R);
▪
extract the aligning device till it touch the core
▪
bit surface.
screw the lock devices (R);
▪
drill for al least 1 cm;
▪
unscrew the lock devices (R) and pull the device
▪
towards the base.
Mounting the core drill motor
Collar mounting
Collar fastening is suitable if the drilling diameter is below
200 mm (drilling in bricks).
The diameter of the collar is 60 mm.
Proceed as follows for the rapid lock collar (figure 7):
position the hand-held core drill into the collar;
▪
tighten the screws of the collar, making sure
▪
that the core drill is securely fastened.
Tilting the column
The column can be tilted for slope drilling applications
(except drill stands without holding bars). Proceed as follows
(figure 10):
Loosen the screws indicated by arrows in the
▪
figure and remove the screws (S) and the plate
(T);
tilt the column;
▪
tighten all the screws loosened before.
▪
When you start drilling, apply light pressure, in order to
prevent core bit shifting.
