follow this warning may result in serious personal
injury. See figure 8 and 9.
Ask your dealer about the best blade for your application.
The blade must have:
•
maximum diameter: 400 mm;
•
hole diameter 30 mm or 25,4 mm. Check the correct
diameter of the hole accordingly to the specification
on the "Technical Data Sheet" supplied together
with the machine;
•
thickness between 2 and 3 mm;
•
maximum rotating speed, given by the blade
manufacturer, higher than the maximum rotating
speed of the wall saw, shown on the data plate (see
figure 12 I).
Use blades with diameter, hole dimension and rotating
speed compatible with your specific wall saw 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.
Blade mounting and replacement
Before mounting or replacing the blade (figure 1 H) make
sure the wall saw is disconnected form the electric supply.
For blade mounting or replacement, follow these directions,
referring to figure 10:
▪
unscrew the blade-tightening screw (10/A), using
the tubular spanner provided with your wall saw;
▪
remove the blade-tightening screw and the flange
(10/B);
▪
insert the new blade or replace the old one (10/C);
▪
insert the flange (10/D);
▪
insert the blade-tightening screw (10/E)
▪
tight the blade-tightening screw (10/F);
Mounting and replacement of the
FLUSH CUT BLADE
Before mounting or replacing the blade (figure 1 H) make
sure the wall saw is disconnected form the electric supply.
For blade mounting or replacement, follow these directions,
referring to figure 11:
▪
unscrew the blade-tightening screw (11/A), using
the tubular spanner provided with your wall saw;
▪
remove the blade-tightening screw and the flange
(11/B);
▪
insert the flange for flush cut blade (11/C);
▪
insert the flange tightening screw (11/D);
▪
tight the flange tightening screw (11/E);
▪
insert the new blade or replace the old one (11/F);
▪
insert the blade-tightening screws (11/G);
▪
tight the blade-tightening screws (10/H);
Fixing the material to be cut and
dimensional limits of the material to be
cut
▪
if the material you are cutting is a block not part of a
construction, fix the block in order to prevent its
movement;
▪
prevent the block from shifting or tearing the
anchorages when you are cutting.

Environmental conditions
▪
do not expose the wall saw 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 wall saw in explosive atmospheres,
for instance inflammable liquids, gas or dust. The
electric wall saw produces sparks which can ignite
dust or smoke.
Overhead cutting (ceiling cutting)
Warning: your wall saw is NOT intended to
perform overhead cutting (upward).

After having followed the instructions given in the previous
Preliminary operations paragraph, follow these directions in
order to perform the cut.
Warning: do not touch any moving parts of
your wall saw, in particular the blade, when
operating.
▪
switch your wall saw on and move closer to the
material to be cut. When the blade touches the
material push till you reach the desired cutting
depth;
▪
your wall saw is intended to perform just straight
cuts;
▪
avoid friction between the blade-side and the
material: move the wall saw just forward avoiding
side movement of the blade. The friction can
overload the motor;
Warning: when cutting, the blade can bind in
the cut causing the saw to kickback. In this
case the saw tends to move toward or away
from the operator. The kickback is dangerous
for the operator and it can cause serious injury.
▪
use the handles and hold your wall saw firmly with
both hands and be ready to resist to a possible
kickback;
▪
cutting materials containing wood, cork, rubber,
foam polystyrene can result in problems moving
forward the machine. If you have this kind of
problems, stop cutting and remove all materials
listed before and proceed with cutting operations. If
you cannot remove these materials, stop cutting
and cut in another position;
▪
in case the electric power goes off, trigger off the
switch to prevent the machine from accidentally self
starting;
▪
when you complete the cut, trigger the switch off
and wait till the blade comes to a complete stop.
Then pull the wall saw out of the cut and close the
water valve. Watch out! The blade
area can be very hot ad cause severe burns.
Electronic devices
Your wall saw is equipped with a CARDI multifunction
electronic device that includes a soft-start and an electronic
clutch:
▪
the soft-start allows the motor soft-start, reduces
current peak that occurs when you switch the motor
on, helps you when you begin cutting, allowing
gradual blade rotation and avoiding jerks at the
operator's arm, and allows you to use your wall saw
