• Detach cassette clamp for a thorough cleaning, removing all paraffin
residues (13).
• For cleaning, do not use xylene. Use xylene substitutes or paraffin
removers such as "Para Gard."
• The cassette clamp (13) can also be placed in an oven heated to a
maximum 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 lubri-
cate the axle and spring of the clamping lever (60) (see also
