• e installation and re-setting up of the instrument is carried out in
reverse order.
• Carefully clean and dry the dismounted microtome.
• Carefully clean and dry the dismounted knife carrier as well.
• As there is condensated humidity inside the microtome, dry the
microtome components inside the cooling chamber very carefully.
• For this, the microtome can be treated in a drying closet at tempera-
ture up to +60°C.
• After each shutting-off or cleaning of the cryostat, the cross roller
bearing should be lubricated.
• By means of a pipette (fig. 132.3) the cross roller bearings (fig.
132.4) can be reached from an angle from behind below the hous-
ing (fig. 132.1).
• Fill the pipette with a small amount of cryostat oil (cat. no.
