• Turn the lever (fig. 78.2) to move the anti-roll plate (fig. 78.4).
If the cutting area of the blade is no longer usable, the blade can be
moved:
• Put the blade slider onto the blade and shift it.
Note:
e blade slider must always be put on in a way that the inscription can be
read.
• is way, it is guaranteed that the slanted edge of the blade slider
shows to the rear side of the blade.
c
aution
To avoid the danger of injury on the blade during adjustment of speci-
men, always position the knife guard over the blade edge.
• e fine adjustment of the anti-roll device is carried out via the
knurled screw (fig. 78.3).
• Loosen the clamping lever as well as the clamping screw on the right
side of the magnetic disposable blade carrier.
• Swivel the upper part of the blade carrier on the base until the desi-
red clearance angle is achieved.
• e clearance angle can be read on the scale on the left side of the
base.
• Again tighten the clamping lever and the clamping screw.
• e selected clearance angle is thus fixed in its position.
Note:
Usable cuts are only achieved with a clearance angle between 24° and 30°.
If the cryostat is equipped with a specimen cooling, the chamber as well
as the specimen temperature is shown on the display (fig. 79).
e specimen cooling of the cryostat is set via the corresponding part
on the operating controls (fig. 80.2).
e actual and set values of the specimen cooling are shown in °C on
the display (fig. 79). On the right side of the display, the actual value is
also shown graphically.
