2-12-4 KNIFE CARRIER S

a) Inserting the knife

The knife carrier S is designed to take triangular

glass knives, diamond and sapphire knives. These

knives are put into the knife insert (fig. 18.8) and

clamped with the clamping screw (fig. 18.9). The

black arrows in fig. 18 show the clamping direction

of the various clamping devices.

b) Adjusting clearance angle

The clearance angle adjustment of the knife can be

set by moving the insert (fig. 18.8) on the upper

part (fig. 18.5). Turn the clamping lever (fig. 18.10)

downwards to lock in the selected clearance angle.

c) Moving the knife sideways

Move the knife carrier together with the upper part

(fig. 18.5) sideways.

Thus, the desired position concerning the specimen

can be adjusted. Loosen the knurled screw (fig.

18.7) slightly. Turn one of the two set screws (fig.

18.6) to achieve the desired side movement of the

upper part (fig. 18.5) with regard to the carrier (fig.

18.3). Tighten the knurled screw (fig. 18.7) slightly

after this positioning.

CAUTION! If the knurled screw (fig. 18.7) is

tightened, do not adjust the set screws (fig. 18.6)

d) Turning the carrier

Loosen the clamping screw (fig. 18.4) to move the

carrier to the left or right side on the socket up to

approx. 30° according to the bowed orientation

scale. Afterwards, tighten the clamping screw (fig.

18.4) again.

e) Moving the knife carrier

on the dovetail guide

Swing the clamping lever (fig. 18.2) to the back to

release the knife carrier. The knife carrier can then

be moved forwards or backwards.
