Frequent switching ON and OFF in succession
Avoid switching on and off several times in quick succession, as a bandsaw machine is not designed to be
switched on and off constantly. This may cause an overload, which will trip the fuses or the motor protection
device. In addition, on larger models with mechanical motor brakes and high flywheel mass, frequent switching
on and off can cause damage to the motor brake. The mechanical motor brakes of the bandsaws are designed
for a maximum of 10 braking cycles per hour.
Switching on and off several times in short intervals can cause damage to the machine
and/or the motor brake.
