6.6.2 Replacement of fuses
To replace the fuses act as follows:
1) Unplug the machine
2) Open the electric panel by releasing the lateral
hooks
3) Remove each fuse from the power board and
individually check their continuity until the
faulty one is found. Remove only one fuse at a
time; once checked, if the fuse is not faulty, put
it back in place before removing the next one.
4) Replace it with a new fuse having the same
electrical characteristics and dimensions
5) Check that the fuse caps have been correctly
put back on
6) Close the electric panel and check that the
machine is working correctly
Warning
When checking the continuity of the fuses make
sure that they are not on a conducting surface.
Warning
Repeated blowing of fuses could be caused by
problems related to devices installed on the
machine;
in this case contact Technical
Services.
