Daily Use of the Instrument

7.4 Sectioning

7.4.1 Inserting the blade/knife holder base

1. To insert the blade/knife holder base

, move the lever

counterclockwise to the back. Slide the base onto the t-piece

of the base plate.

Note

When inserting the blade/knife holder base, overcome the resistance of a spring (located in the foot of

the knife holder) by applying a little pressure toward the left.

2. To clamp the blade/knife holder base, turn the lever

clockwise (towards the

front).

3. If the blade/knife holder base is to be moved in the cryochamber, grab the base by both of the

plastic points

to prevent freezer burn injuries.

Fig. 26

Adjust the clamping force of the t-piece

To ensure a proper sectioning result, the knife holder base

must be securely clamped onto

The clamping is carried out using an eccentric lever

. The clamping force is adjusted with

the setscrew

on the upperside of the t-piece. The setting of the clamping is carried out so

that the clamping lever can be rotated to the stop with constantly increasing resistance.

To set the clamping distance from the eccentric bolt to approx. 200 °, do the following steps.

1. Remove the knife holder base from the base plate.

2. Adjust by screwing clockwise or counterclockwise the countersunk screw

clamping piece in the base using the Allen key No. 4, so that the eccentric lever

can be clamped at 0 ° position and 200 ° position.

Repeat this procedure until the knife holder base is securely clamped and not moving.
