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
z
.
Caution!
The braking lever (3) must be exactly in
position
z
, 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

•
To lock the handwheel, press the lever (
5
)
outwards and continue to turn the hand-
wheel 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
c
first. Otherwise, it may be not
be possible to release the lever (5).
