The instrument is basically maintenance-free.
To ensure trouble-free operation of the instrument over a long period of time, the following is recommended
by Leica:
1. Thoroughly clean the instrument on a daily
basis.
2. Enter into a service contract at the latest at the
end of the warranty period. For more informa-
tion, please contact your local Leica technical
service center.

• Detach cassette clamp (13) for a thorough cleaning, removing all paraffin
residues.
• For cleaning, do not use xylene. Use xylene substitutes or paraffin re-
movers such as "Para Gard."
• The cassette clamp (13) can also be placed in an oven heated to a maxi-
mum of 65 °C, until the liquid wax escapes.
• Remove paraffin residues with a dry cloth.
• After such a cleaning procedure in an oven, always be sure to lubricate
the spiral springs (91) of the tension lever (60)
and move it back and forth several times.
