There are two ways of locking the handwheel ( → "Fig. 2- 1 ") :
• Using the handwheel locking mechanism ( → "Fig. 2- 2 ") on the top of the handwheel, the handwheel
can be braked in the 12 o'clock position.
1. To lock the handwheel, press the handwheel locking mechanism (
→
"Fig. 2- 2 ") outwards and
continue to turn clockwise the handwheel slowly until it locks exactly in the 12 o'clock position.
The yellow LED in the
M-STOP
field ( → "Fig. 3- 1 ") lights up.
2. To unlock the handwheel, turn the handwheel locking mechanism ( → "Fig. 2- 2 ") inwards.
Caution
Operating the handwheel locking mechanism during motorized sectioning.
Instrument in malfunction and delayed diagnosis.
• Never operate the handwheel locking mechanism during motorized sectioning.
• To stop the motorized sectioning, use the RUN/STOP button or ENABLE button or the BRAKE
button on the separate control panel ( → P. 49 – Start and stop motorized sectioning).
• Using the handwheel brake lever ( → "Fig. 2- 3 ") on the right side of the microtome base plate, the
handwheel can be braked in any position.
1. To brake, pull the handwheel brake lever forward forcefully and completely.
Warning
The handwheel brake lever is not used properly, and the handwheel cannot be braked.
Serious injury of instrument/persons, or specimen damage.
• The handwheel brake lever must be exactly in the locked position. If the handwheel brake lever
is moved beyond this point, it is possible that the handwheel is no longer braked.
2. To unlock the handwheel, push the handwheel brake lever ( → "Fig. 2- 3 ") back to its original
position.
The yellow LED ( → "Fig. 3- 1 ") in the M-STOP field flashes if the handwheel brake lever is not locked
completely. The handwheel brake lever ( → "Fig. 2- 3 ") must be pulled completely forward with force so
that the handwheel brake is applied.
