2. Safety
Knife guard on the knife holder
Each knife holder is equipped with a tightly
mounted knife guard (8, 9). This makes it possible
to cover completely the cutting edge in every
knife or blade position.
Knife holder N/NZ
The knife guard (8) of the knife holder N/NZ
can be easily positioned via the two handles (7)
( Fig. 5 ).
To cover the knife edge, push both cover strips
of the knife guard to the center.
Knife holder E
The knife guard on knife holder E consists of a
red foldaway handle. To cover the cutting edge,
fold the knife guard handle (9) upwards as illus-
trated in Fig. 6 .

Centering the handle

must always be centered while in motorized
sectioning mode.
• Activate the handwheel lock.
• To center the handwheel, lightly pull the han-
dle (6) outwards and swivel it into the center
of the handwheel (12) ( Fig. 4 ).
• The handle will then lock automatically when
released.
