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. 43.3) on the

right side of the knife carrier and move the

upper part of the knife carrier (fig. 43.2) on the

base (fig. 43.1).

• The adjusted clearance angle can be read on

the scale.

• Then turn the clamping lever (fig. 43.3)

upwards to lock in the new clearance angle.

Note:

By experience, usable cuts are only

achieved at a clearance angle of 10° or

more.

• If the clamping lever (fig. 43.3) 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.

• The clamping lever for the angle adjustment

can be pulled off after a correct angle setting to

avoid that the angle is "reset" unintendedly.

Moving the knife carrier on the console:

• Loosen the clamping lever (fig. 43.6) on the left

side of the knife carrier, to move the carrier

forwards or backwards on the dovetail guide.

• This allows a rough adjustment of the knife to

the specimen.

Protection against injury:

• A bracket (fig. 43.4) on the clamping plate can

be moved upwards over the blade for the

protection against injury.
