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
connected to the household electric system
equipped with high sensitivity automatic switch;
the electronic clutch ensures that the current
absorbed by your wall saw, proportional to the
motor load, is below the safety upper limit. In case
the current absorbed exceeds the limit, it cuts off
power toward the motor, preventing damages.
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 wall saw is not used properly. Possible
causes can be a not suitable forward speed, an
excessive friction between the blade-side and the
material, excessive cutting depth. In these cases,
stop cutting and let the machine turn with no load
for some seconds, helping the motor cool down.

Periodic maintenance
at the end of the work, after having removed the
blade, blow compressed air inside the rotating
motor in order to remove dust and powder. Do this
operation wearing protective goggles;

unplugged;
keep your wall saw clean and dry, in particular its
handles and its moving parts;
never use solvents or other harsh chemicals for
cleaning your wall saw;
after use put your wall saw in a dry, safe and
inaccessible to children place;
we recommend to lubricate hinges, joints and pivots
belonging to cutting-depth setting system with a
suitable water-repellent spray
gears are lubricated by lubricating oil and grease
which are suited for any external temperature. You
don't have to check the oil level or to fill it up.
always unplug the wall saw during check or blade
replacement;
never unplug the wall saw pulling the cord;
