7. Cleaning and maintenance
7.2 Changing the fuse
If the instrument fails completely, first check the
power supply at the power socket.
Then check the fuses at the rear side of the
instrument.
To do so, proceed as follows:
• Using a screwdriver (13), carefully push out
the fuse insert (14) (Fig. 33 - top).
• Remove the fuse insert - it contains two fuses
(15).
• Check that the thin wire (16) in the glass capil-
lary of a fuse is intact. If not, replace the fuse
(the standard scope of delivery includes two
replacement fuses).
• Insert the fuse insert with the two fuses and
start up the instrument again.

Before changing a fuse, always switch off the instrument first and remove the instrument cable
completely. The instrument must have cooled down and the paraffin tank must be empty.
When changing a fuse, do NOT use any fuses other than the spare fuses supplied with the instru-
ment.

Before plugging the power cable back
in and switching on the instrument, you
must have identified and corrected the
cause of the burned-out fuse.
