Indication of remaining horizontal feed
The visible and audible remaining feed indication
feature informs the user during trimming and
sectioning when a remaining feed of approxi-
mately 1 mm is available before the front limit is
reached.
The yellow LED (41) in the COARSE FEED button
lights up from the beginning of the remaining
feed. In addition, an acoustic signal is heard for
approx. 2 seconds.
The sectioning process is interrupted and the
object head stops in the upper end position.
From this point on, a remaining feed of approx.
1 mm is available.
In the remaining feed area, no more object feed-
ing to the knife is possible using the coarse feed
buttons.

automatically.
