5.5.11 Fixed-setting declination blocks
(45°) and knife holder A or C
When knife holder A or C is combined
with the declination blocks, the knife
guard (9) cannot be placed over the
knife edge. Therefore, use extreme
caution when working with this con-
figuration - wear cut-resistant gloves!
Installing knife holder A
• Place left declination block (1) (bearing the
clearance angle scale (7)) onto the left bear-
ing block of the microtome and secure with 3
screws (4) (Allen key size 8) .
The bearing surfaces must be clean.
Place the declination blocks onto the
bearing blocks from above. Do not
slide them onto the blocks to prevent
the bearing surface from getting
scratched.
• Slide the left pin (3a) of knife holder A into the
declination block (1).
• Slide right declination block (2) onto right pin
(3a) of the knife holder and fasten to the mi-
crotome with 4 screws (5) (Allen key size 8).
Tighten one of the Allen screws (6)
with an Allen key size 8 to secure the
knife holder in position!
Put on cut-resistant gloves (see also
chapter. 8.1 ‘Additional accessories’).
• Insert the knife into the holder from below
(with the facet pointing downwards).
The combination ‘Declination blocks /
knife holder A’ can only be used for
knives up to max. 22 cm length.
