Finger guards
The finger guards are integrated into the clamp-
ing jaws. Use handles (19) to slide them back and
forth. The width of the finger guards is sufficient
for knives up to 22 cm long. Once you finish sec-
tioning, always cover the knife edge with the fin-
ger guards.
Prior to any work on knife and object,
each time before changing the speci-
men block and during work breaks the
knife edge must be covered with the fin-
ger guards!
Shifting the clamping jaws
In the factory, the clamping jaws are mounted at
a distance of 64 mm from each other. If neces-
sary, the clamping jaws can be relocated to a dis-
tance of 84 mm.
To shift the clamping jaws the knife holder must
be removed from the knife holder base. Loosen
lever (20) and remove knife holder from base. With
a size 4 Allen key, loosen the screws (21) located
at the bottom surface of the knife holder. Shift the
clamping jaws (22) and retighten the screws. Insert
the longer of the two knife support bars (part of stan-
dard delivery).
Never work with just one clamping jaw.
Otherwise sufficient stability for the
sectioning process cannot be guaran-
teed. In addition, long knives will no
longer be sufficiently covered by the fin-
ger guard.
