until it slides off the segment arc.

1. To release the segment arc (1) from the

2. Fold the anti-roll system (3) to the left using
the lever (4).
3. Open the clamping lever (5) by turning it
counterclockwise.
4. Hold pressure plate (6), and remove bolt

For daily cleaning, remove the section waste from the blade holder using a dry brush. Please use
a cold brush, as otherwise the section waste will thaw and stick to the blade holder.
Mechanical damage to the pressure plate will strongly affect the sectioning quality. For this
reason it is important to ensure that the clamping area is not damaged during cleaning or other
work.
For disinfection, commercially available, mild cleaners and disinfectants can be used – we rec‑
ommend Leica Cryofect (not available in the USA).
Wear gloves during cleaning to prevent frostbite.
If several blade holders are cleaned at the same time, the parts must NOT be mixed up! Failure
to adhere to this may result in sectioning problems!
