2.2 - POSITIONING
Position the pallet, with the slicer, on a
flat surface and take off (a) the sharpe-
ner from the slicer (Fig. n°12).
At this point turn the machine on its
side (Fig. n°13) and unscrew, with the
proper wrench provided, the 4 nuts
which fasten the slicer. Remove the 4
washers and unscrew the 4 fastening
tie rods on the wooden pallet. Take off
the pallet and fasten the 4 feet provi-
ded. Finally, put the sharpener in its
place.
Position the slicer in the predestined
place.
The dimensions indicated in Tab. 1
(according to the model) must be kept
in mind for the plane where the slicer
will be installed, therefore it must be
wide enough, well-levelled, dry, smo-
oth, robust, stable about 80 cm high off
the ground and at least 20 cm from
walls, objects, shelves, etc. (Fig. n°14)
in respect to the space necessary for
its use and safeguarding.
Furthermore the machine must be pla-
ced in an environment with a maximum
humidity of 75%, not salty and with a
temperature between +5°C and +35°C;
in any case in environments which do
not lead to deviations of the above.
Make sure the graduated handgrip is in
posiion “0”.
Check the alignment of the blade-plane
thickness gauge by running a finger
(Fig. n°16) from the blade towards the
thickness gauge plane (never in the op-
posite direction). Unscrew and screw
the foot (1) until the correct alignment is
found (Fig. n°17), then screw the rub-
ber part (2) to fix everything (Fig. n°17).

Even though the professional CE slicers are equipped with the standard mea-
sures for electrical and mechanical protection (both while operating and during
cleaning and maintenance), RESIDUAL RISKS which cannot be completely eli-
minated in any case exist, highlighted in this manual under the form of WAR-
NING. They concern the danger of cutting, bruising and other caused by the bla-
de or by other machine parts.

CHAP. 5 - MACHINE USE
5.1 - OPERATIONAL CHECK
For the 1° use follow these
instructions:
-check that installation has been car-
ried out correctly as in chapter 2;
-check that the plate is well fastened
with the lock handgrip (Fig. n°34
ref.1);
-check the sliding of the plate and that
it is free of obstacles on the work
counter for all of its run (Fig. n°35
ref.a);
-check that the goods pressing arm
easily rises and lowers so that it is not
impeded in all its movement (Fig. n°
35 ref.b);
-check the opening of the thickness
gauge plane by making the numbered
handgrip turn clockwise and counter-
clockwise (Fig. n°36 ref.c);
-check that the sharpener is well
fastened to the machine and that it is
easy to extract and free of obstacles
(Fig. n°37 ref.d).

Adhere to the following procedure:
1.Lift the goods presser, load the goods
on the plate, bringing it close to the
thickness gauge, block it with the pro-
per toothed arm;
2.regulate the desired thickness of the
cut with the graduated handgrip;
3.assume a correct position to avoid
accident: place the right hand on the
goods presser handgrip and, then the
left hand next to the slice guard to
take the cut product (without tou-
ching the blade); the body must be
perpendicular to the work plane (Fig.
n°38).
WARNING: Do not assume positions
which bring body parts in direct
contact with the blade (ex. Fig. n°
39);
4. then push the “ON” push-button;
5. push the carriage (plate + goods
presser arm + stem) gently towards
the blade, without applying excessi-
ve pressure on the product with the
goods presser arm. The goods will
easily enter the blade, and the slice
guided by the proper sliceguard will
detach and fall on the plane (Fig. n°
40);
6. avoid running the slicer when empty;
7. t the end of the cutting operation,
stop the machine by putting the
switch in the “OFF” position and put the graduated handgrip at “0”;
8. Carry out resharpening the blade as soon as the cut product has a threaded
or rough surface, therefore the cutting effort increases (chapter 5.3).
5.2 - LOADING AND CUTTING THE PRODUCT
WARNING: The goods to be cut are loaded on the plate only with the graduated
handgrip at “0” and the motor stopped, being careful with the blade and the
points.
