Using high profile blades:
When using high profile blades, first remove the
spacer strip (fig. 42.3).
• For this, turn the clamping lever (fig. 42.7) to
the front until the stop.
• The press the stop pin into the knife carrier and
further turn the clamping lever (fig. 42.7).
• Pull off the clamping lever (fig. 42.7) and
remove the clamping plate (fig. 42.3).
• Insert the clamping plate and clamping lever
again.
• Push the stop pin into the knife carrier and turn
the lever into an upright position.
Clearance angle adjustment:
• The clearance angle between cutting edge and
specimen can be shifted and adjusted to the
respective requirements of the tissue to be
sectioned.
• Loosen the clamping lever (fig. 42.8) on the
right side of the knife carrier and move the
upper part (fig. 42.9) of the knife carrier on the
base (fig. 42.1).
• The adjusted clearance angle can be read on
the scale.
• Then turn the clamping lever (fig. 42.8)
upwards to lock in the new clearance angle.
• The clamping lever for the angle adjustment
can be pulled off after a correct angle setting to
avoid that the angle is "reset" unintendedly.
Note:
By experience, usable cuts are only
achieved at a clearance angle of 10° or
more.
Moving the knife carrier on the console:
• Loosen the clamping lever (fig. 42.6) on the left
side of the knife carrier, to move the carrier
forwards and backwards on the dovetail guide.
• This allows a rough adjustment of knife to
specimen.
Protection against injury:
• A bracket (fig. 42.4) on the clamping plate can
be moved upwards over the blade for the
protection against injury.
