2.3.3 ANTI-ROLL ASSEMBLY CONT.
Step 2: Setting the Anti-Roll Plate
To ensure optimum sectioning performance
the anti-roll plate must be kept clean from
grease and dirt. To clean the anti-roll plate
carefully apply a small amount of methylated
spirits or ethanol to both the upper and lower
surfaces using a clean, dry, soft paper towel.
a. Place the Roll plate against the knife to
see where the Roll plate edge is positioned
in relation to the blade edge, the edge of the
Roll plate should be positioned slightly below
the knife edge, if this not the case, use the
adjustment knob to reposition.
NOTE:
if the edge of the Roll plate is
above the edge of the knife lift it from the
knife to adjust, dragging the Roll plate
downwards while on the knife could result
in damage to the Roll plate and knife).
b. Lightly tighten the Anti-Roll adjustment
lock so that the Anti-Roll adjustment knob
can still be turned.
c. Place the Roll plate back against the
knife and start to cut sections again. If the
plate is too low they will curl up on the tip
of the knife.
d. Loosen the Anti-roll adjustment knob and
adjust the angle between the bottom face
of the plate and the blade, set the angle
somewhere between 10°-15°.
e. Slowly turn the anti-roll adjusting knob
clockwise while cutting sections. When the
plate reaches the correct height, the sections
will start to slide under the plate.
f. Tighten the Anti-roll adjustment lock then
flip the plate away from the knife. Now flip
the plate back into position. When cutting is
resumed, sections should go under the plate
as before, i.e. the plate has aligned itself.
If not, repeat the setting up process.
Your anti-roll plate may vary from the design
shown, but the set-up procedure remains
the same. Please refer to section 3.6, Frozen
Sectioning: A Problem Solving Guide, for
further assistance.
Note: The Anti-Roll
plate doesn’t sit
flush onto the knife.
Start with roll plate point
below the point of the knife
and advance it forward while
sectioning until sections
slide underneath plate.

Refer to Figure 4.
2.4.1 BLADE GUARD
When access to the blade is required, the
blade guard can be opened. Flip it downwards
to open and flip it upwards to close.
During sectioning, the wire blade guard is in
the open position. At all other times when
a blade is fitted, the guard should be in the
closed position for operator safety.
