ELECTRIC FUSES AND THERMAL CUT-OUTS
In addition to general 80 A fuses, the machine is also fitted with self-restoring safety fuses located on
the boards in the electric system that interrupt the power supply to the brush and suction motors when
the machine exceeds the predetermined load. To restore the power supply to the motor, switch off the
machine and wait for the fuses to cool down (about 40 seconds). If the switch disconnects the current
several times in a row, contact the COMAC technical assistance centre.
