CHECKING OPERATION
1.
ELECTRIC SYSTEM SAFETY
The machine has two amperometric safety switches installed in the electric system (below the
solution tank). These cut off power to the brush motor and to the suction motor when a preset load is
exceeded. The restoration of the motors happens in automatic after switch off the machine and wait
around 40 seconds for the cooling of the protection inserted in the electric card. In case in which the
machine blocks itself several times, it is necessary to apply to a
BETCO
service center.
