The pointing out of
any difficulties and
their elimination
The supply line is attributed with the
cause of the most common difficul-
ties. In the case of breakdown, pro-
ceed as follows:
1)
Check the value of the supply volt-
age
2) Check that the power cable is per-
fectly connected to the plug and the
supply switch
3) Check that the power fuses are not
burned out or loose
4) Check whether the following are
defective:
• the switch that supplies the
machine
• the plug socket in the wall
• the generator switch
NOTE: Given the required technical
skills necessary for the repair of the gen-
erator, in case of breakdown we advise
you to contact skilled personnel or our
technical service department.
