Handwheel Brakes
Before placing or removing a specimen on the specimen head, or adjusting the orientation, always ensure
that the mechanical handwheel brake is engaged. The cryostat is equipped with an electronic and a
mechanical handwheel brake to prevent unintended movement of the specimen head.
Activating the brakes reduces the risk of being injured when adjusting the specimen head and/or the blade
carrier.
When the instrument is turned off, the electronic hand wheel brake cannot be activated!
Whenever the instrument is turned off, the mechanical hand wheel brake has to be

For your personal safety, both electronic and mechanical hand wheel brakes must always
be activated when working on the specimen head or blade carrier.
