9.7 Checking and replacing fuses
Fuses should be checked with an instrument for measuring their continuity (tester, ohmmeter, multimeter,
etc.) as they may appear to be good condition to the naked eye even when they are electrically faulty.
Fuses must always be replaced with others of same type (rapid or delayed) and with the same amps, as
given in the manual.
There are five fuses in the MARKER 2000.
• 2 fuses:
3.15 Amps rapid (220V)
4 Amps rapid (110V)
situated in the power socket on the back of the
machine, next to the switch (I) (fig. 38). They protect
the machine from the power variations and short
circuits.
To check and replace, if necessary, proceed as
follows:
1) turn off the master switch and remove the plug.
2) use a screwdriver to open the flap covering the
socket, remove the fuses and replace, if neces-
sary.
