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
Earth
▪
since your wall saw operates with water, its metallic
parts are connected to the earth;
▪
make sure that the socket and possible extension
cords and multiple sockets have the earth
connection and that your electrical system is
properly connected to the earth.
Warning: for your safety, it is important that
the whole system (electrical system, extension
cords, sockets etc.) is connected to the earth.
If you are not sure, ask a qualified electrician
for a check.
Extension cords
▪
when you have to operate with your wall saw far
from an electrical socket, you can use an extension
cord. If you use it, make sure that the section of the
cord is suitable and that the cord is provided with
ground conductor;
▪
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 13 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 13;
▪
remember that the more an extension cord is long
the more the voltage drop is high and the worse is
the operation of your wall saw. Do not use
extension cords if you have to operate too far from
the electrical socket.
Preliminary operations
In order to prepare your wall saw to operate, follow these
steps. Before proceeding with preparation make sure that
the plug is disconnected from the power supply.
a) b) fix the main handle (A) in the more comfortable
position for the application as shown in figure 4.
Warning : not using handles can result in loss of
control of your wall saw and serious personal
injury.
b) connect the quick hose connector (C) to a proper
water supply;
PRCD: portable residual current device
▪
your wall saw is equipped with a safety portable
residual current device (PRCD) assembled on the
cord. This device is shown in figure 5;
▪
never use the wall saw without PRCD;
▪
before starting to cut, make sure the PRCD works
properly. In order to do so, plug the wall saw in and
press the button
Reset (O): a red led will light up
(P) showing that electricity is available toward the
wall saw. Than press the button
Test (N) that tests
if the device works properly. When you press it the
circuit breaker inside the PRCD should cut the
power off leading the switch automatically to go to
the off position and the red led to go off;
▪
if, when cutting, the PRCD cuts the power: stop
working, set the switch on OFF position and bring
your chain saw to an authorized service centre in
order to remove the causes of the electrical
dissipation.
ON/OFF switch
See figure 6 in order to understand how to use the switch
(figure 2 E).
Your switch is equipped with a safety lock-off device. This
device ignite the motor only if you follow first step I and than
step II, as shown in figure 6. This prevents the wall saw from
accidentally self-starting.
Connection to a water supply
Wet cutting reduces risks connected with dust spreading.
We recommend to use your wall saw with water. If you want
to cut without water wear a proper dust mask to protect
yourself from dust. In wet cutting:
▪
check at regular intervals that none of the water
system components are damaged. Check in
particular the valve, the quick hose connector and
the pipe;
▪
use only the water pipe provided with your wall
saw. The water pipe includes also a valve and a
quick hose connector ;
▪
the maximum pressure of incoming water must be 4
bar;
▪
use just clean water;
▪
prevent water from entering the motor or other
electrical components.
Checks and precautions to avoid
structural damages and damages to the
plant
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 electric
mains.
Blade choice
Your Cardi wall saw has been designed to cut building
materials such as concrete, reinforced concrete, bricks,
masonry, natural stones, tiles etc, using laser welded
diamond blades (figure 9).
Warning: Do NOT use circular saw blades or
other kind of blades not laser-welded. Failure to
