Some saws have been manufactured with electrical resistors and varistors that can be damaged by fluctuating voltages while connected to mains electricity. These damaged components can then become hot or start to smoulder if they continue to experience fluctuating voltage. This could also result in the saw catching fire.
What are the hazards?
Injury to the user may occur due to melted or smouldering parts or fire. Property damage could also occur.
