6. Operating the VibroCheck
Prior to assembly, the dovetail guide (3) is brought
down to the lowest position using the DOWN key!
1. The user installs the VibroCheck: the VC is
pushed along the dovetail guide (3) past the
mark on the base plate of the instrument (rear
stop) and clamped firmly using the lever (15).
Insert the blade and clamp tightly. Return the
blade to the cutting position (see Fig. 19).
2. Plug the connecting plug of the VibroCheck
(VC) into the corresponding socket on the left
side panel. The LED on the VC quickly flashes
red --> then it remains red. The control panel
detects the VC (see Fig. 30). The LED in the
DOWN key flashes green.

3. The user presses the DOWN key. The VC
moves to the bottom position, in addition to that
the blade moves to the rearmost position – the
LED in the RUN/STOP key flashes. Short red
flash of LED on VC --> it then remains red.
4. The user presses the RUN/STOP key: the blade
first moves towards the front (into the posi-
tion exactly above the VibroCheck); the VC
then moves into a position in which the blade
partly covers the light barrier. LED on VC flash-
es green – RUN/STOP flashes yellow. The con-
trol panel displays: "VIBRO search" (see
Fig. 30). A search can last up to 1 minute. When
LED on VC is green and LED in RUN/STOP is
yellow, the blade starts to vibrate.

We recommend using the VibroCheck after each blade change for check-
ing the optimum position of the blade and important sectioning parameters.
