Locking the handwheel
There are two ways of locking the handwheel (12):
Using the lever (3) on the right side of the micro-
tome base plate, the handwheel can be braked
in almost any position.
• To brake, rotate the lever in a counterclock-
wise direction to position .

• To lock the handwheel, press the lever (5)
outwards and continue to turn the handwheel
slowly until it locks exactly in the 12 o'clock
position.
In both cases the yellow LED (4) in the LOCK will
be lit and the instrument cannot be started.
When using both brake systems at the
same time, always move the lever (3) to
position
 first. Otherwise, it may be
not be possible to release the lever (5).
Caution!
The braking lever (3) must be exactly
in position , so that the handwheel
brake is applied correctly.
If the lever is moved beyond this point,
it is possible that the handwheel is no
longer braked.
• To unlock the handwheel brake turn the lever
(3) back to its original position. Position 
