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: Push the VC
along the dovetail guide (3) to behind the mark
on the baseplate of the instrument (rear stop)
and clamp it down 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. Short red flash of LED on VC --> it
then remains red. Control panel detects 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: First, the
blade moves forward (into the position exactly
above the VibroCheck), then the VC moves
into a position in which the blade partially
covers the light barrier. LED on VC flashes
green - RUN/STOP flashes yellow. Control
panel shows: "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 checking the optimum posi-
tion of the blade and important sectioning parameters.
