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.
