PROBLEM CAUSE REMEDY
1)
The cutting in of the self-resetting protection of the electronic card is signalled by a beep, except in cases where the
battery is missing, at or with the terminal crossed. The signal stops when the key is returned to position «OFF»; then
wait a few seconds before returning to position «ON».
IMPORTANT Faulty electronic cards must always be replaced without trying to repair them or re place single
components.
WARNING! The selfsetting guard reaches very high temperatures (around 180 °C) which are to be consid
ered normal. Similarly, there might be some smoke inside the box which is due to the overheating of the powder
inside. Do not touch this component of the circuit board until it has cooled down.
