Read carefully the data written on the Technical
Data sheet that you will find in the package
together with your product.
In the following text, figures are identified by numbers,
details inside the figures by letters. Figures are depicted on
the first pages of this user manual.
Power supply
Extension cords
when you have to operate with your wall chaser far
from an outlet, you can use an extension cord. If
you use it make sure that the section of the cord is
suitable;
the extension cord (made up of cable, plug and
socket) must be suitable for outdoor use. It is better
if the cord is made of rubber and it is H07RN-F;
follow the chart shown in figure 14 on this manual
for the choice of the right section of the conductors;
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 14, considering the total length of the
extension cords;
remember the longer an extension cord the higher
the drop in voltage. This causes loss of rpm and
therefore cooling as well as loss of power
operating your wall chaser. Don't use extension
cords if you have to operate too far from the
electrical outlet.
Preliminary operations
In order to prepare your wall chaser to operate, proceed as
follows, make sure before you start that your machine is
unplugged.
set the B handle (figure 1) in one of the two
possible positions. To change the position of the
handle, loosen the wing-nut, when the handle is not
engaged turn it (see figure 6). Before tightening the
wing nut, make sure the handle is engaged (pins go
into the holes). Before operating, make sure the
handle is securely fastened;
Warning: not using auxiliary and main handles
can result in loss of control of your wall chaser
and serious personal injury.
connect an industrial vacuum cleaner to the wall
chaser according to the direction given in the Dust
extraction paragraph;
insert the blade/s according to the instruction given
in the Blade mounting or replacement paragraph;
if available, set the cutting depth according to the
paragraph Setting the cutting depth.
ON/OFF switch
See figure 5 in order to understand how to use the switch
(figure 2 E).

Your switch is equipped with a safety lock device. With this
device you can switch on the motor only if you follow first
step I and than step II, as shown in figure 5. This prevents
the wall chaser from starting accidentally.
Warning: after switching off, the machine will
not be idle immediately.
Checks
and
precautions
structural
damages
objects
Before starting any cutting activity, talk with the construction
manager or the planner in order to make sure that the cut
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 electrical
circuits.
Blade choice
Your Cardi wall chaser has been designed to make grooves
into building materials such as concrete, reinforced
concrete, bricks, masonry, natural stone, tiles etc, using
laser welded diamond blades (figure 8 and 9).
Warning: Do NOT use circular saw blades or
other kind of blades not laser-welded. Failure to
follow this warning may result in serious personal
injury. See figure 8 and 9.
Ask your dealer about the best blade for your application.
You can mount to your machine, depending on your model,
2 or 3 blades. See the Technical data sheet that you will find
in the package for dimensional limits of blades. The blade
must have maximum rotating speed (provided by the blade
manufacturer), higher than the maximum rotating speed of
the arbor of your wall chaser, shown on the data plate (see
figure 7).
Use blades with diameter, arbor hole and rotating speed
compatible with your specific wall chaser model. Use of
blades
with
inappropriate
misalignment, vibrations, irregular rotation and loss of
control causing serious injury.
Check the blade before use. Do not use damaged blades.
Mounting the blade and setting the cutting
width
Before mounting or replacing the blades, make sure the wall
chaser is unplugged. For blades mounting or replacement,
proceed as follows, referring to figure 10:
remove the protective cover by loosen the screws
with a screwdriver (10/A);
loosen and remove the blade-tightening screw
using the Allen key provided. Than remove the
flange. See figure 10/B;
remove the spacing washers (10/C);
insert the blades, placing the spacing washers
between them (see figures 10/D and 10/E). You
can set the cutting width positioning a different
number of spacing washers between the blades.
Depending on your model, you can mount 2 or 3
blades;
when the blades and ALL spacing washers have
been positioned, assemble the flange (10/F);
tighten the blade tightening screw, making sure the
blades are firmly fastened (10/G);
Warning: before operating always ensure the
blades are firmly fastened.
