3-6 SPECIMEN FEED
3-6-1 COARSE FEED
For the fast forward and backward travel between
specimen and knife edge, the microtome has a
coarse feed system.
• By means of the coarse feed wheel (fig. 6.1)
the specimen holder can be moved
horizontally backwards and forwards.
• When the front end position of the specimen
feed is reached, a resistance can be noticed
and when the handwheel for the cutting drive
is activated an acoustic signal can be heard.
Warning:
Do not continue to advance the
specimen after reaching the front end
position with the coarse feed wheel or
the handwheel. This will damage the mechanical
parts.
Warning:
When turning the coarse feed wheel,
take note that the specimen and knife
edge do not get in contact with each
other.
Note:
At the beginning of a sectioning series,
it is advisable to use the coarse feed to
move the specimen to the back third of
the horizontal specimen movement and to move
the knife carrier towards the specimen feed.
