Only qualified and authorized service person-

The microtome is maintenance-free in operation to a
great extent!
To ensure reliable and trouble-free operation over sev-
eral years, we recommend the following:
• Have the instrument inspected by a qualified ser-
vice engineer authorized by Leica at least once a
year.
• Enter into a service contract after the warranty pe-
riod; for further details, please contact your Leica
sales office.
• Clean the instrument every day.
• From time to time, especially after repeated drying
in a heating oven, apply a drop of cryostat oil - to
the clamping lever of the knife holder and the clamp-
ing screw for fixing the specimen discs. Fig. 31.2
