Maintenance

11.1 General maintenance

Only qualified and authorized service person-
nel may access the internal components of the
instrument for service and repair.
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: Apply a drop of cryostat oil - from
time to time - especially after repeated drying in a
heating oven, to the following components:
- Clamping piece (T piece) and clamping
lever of the microtome base plate
- Guide of the knife holder base
- Clamping lever of the knife holder base
- Press the coarse feed button to move the
specimen cylinder out to the front limit.
Apply some drops of cryostat oil to the
cylinder. Press the coarse feed button
again to move it back to the home posi
tion (rear limit).
• Clean the ventilation grid of the compressor at the
bottom of the right cabinet side wall with a brush or
vacuum cleaner in the direction of the fins to re-
move dust and dirt.
