5.4.3 Selecting sectioning speed

• Sectioning speed is selected via the sliding
potentiometer. Speed can be changed while
sectioning is in motion.
Caution when working in continuous mode:
If the slider is set to '0', the sectioning motion
stops, however, the actual sectioning mode is
still active - just operating at '0' speed.
If the slider is accidentally moved, sectioning
will be resumed! - Risk of injury!
Therefore:
Do not interrupt sectioning / trim-
ming by setting the sliding potenti-
ometer to zero speed!

ter 2.3.6 'Motorized sectioning'.
