Working with the Instrument
8.4.2 Trimming with Extraction – Anti-roll Guide Installed
Remove the silicone stopper from the filter cover (and keep it in a safe
place).
Insert the extraction hose with the black adapter.
Fold the anti-roll guide to the side and fasten the suction nozzle to the
pressure plate – see mark Fig. 39a - (using 4 magnets on the rear side of
the nozzle).
Fold the anti-roll guide back into position.
E
Ensure that the hose with the nozzle is
not installed against its "natural" cur-
vature on the pressure plate of the
blade holder.
The tension acting on the hose can be minimized
by turning the red ring (Fig. 39, top right) clock-
wise so that the suction nozzle presses against
the pressure plate (I, Fig. 39).
