The microtome is virtually maintenance-free. To ensure
a smooth operation of the instrument over several years
we recommend the following:
• Have the instrument inspected by a qualified ser-
vice engineer authorized by us once a year.
• Enter into a service contract at the end of the war-
ranty period. For further information, please con-
tact your local Leica service center.
• Clean the instrument daily.
• From time to time:
lubricate the seat of the heat extractor (1), the
clamping piece (T piece) (2) and the clamping lever
(3) on the microtome base plate as well as the speci-
men cylinder (4) slightly with cryostat oil. Press the
coarse feed button (5) to move the specimen cylin-
der forward, apply some drops of oil on the cylin-
der and move it back to the final home position.
• Clean the ventilation slits of the liquefiers on both
sides of the instrument with a brush, broom or
vacuum cleaner to free from dust and dirt in the di-
rection of the fins.
• Do not carry out any repairs on your own as this
will invalidate the warranty.
Repairs may only be carried out by qualified ser-
vice engineers authorized by Leica.
