3-11-3 KNIFE CARRIER C

• To insert the knife, the clamping screws (fig.

44.3) must be unscrewed slightly so the knife

can be pushed in from the side.

• The height of the knife is adjusted with the two

knurled nuts (fig. 44.6) and the bar (fig. 44.7).

• If the cutting zone of the knife cannot be used

anymore, it can be moved over its entire length

to the left and right side by loosening the

clamping screws.

• This allows an optimal use of the entire knife

edge.

Caution:

When clamping the knife, please

tighten the two clamping screws (fig.

44.3) simultaneously.

Clearance angle adjustment:

• The clearance angle between cutting edge and

specimen can be shifted and adjusted to the

requirements of the tissue to be sectioned.

• Loosen the clamping lever (fig. 44.4) on the

right side of the knife carrier and move the

upper part of the knife carrier (fig. 44.2) on the

base (fig. 44.1).

• The adjusted clearance angle can be read on

the side scale.

• Then turn the clamping lever (fig. 44.4)

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.

• If the clamping lever (fig. 44.4) is loosened, the

upper part of the knife carrier can be moved 1

cm to the left or right side.

• This way, the cutting edge can optimally be

used.
