When the package is received, if there is no
external damage proceed to opening it, ma-
king sure that all material is inside. If the
package upon delivery shows signs of tam-
pering (Fig. n°8), impact or fall, it is
necessary to present the damage to the
carrier, and within 3 days of the delivery da-
te, indicated on the documents, make a
precise report of the damage. Do not over-

Heavy package. Do not lift manually
unless with help of at least three people
(Fig. n°5).
Move the package only by electrical
trolleys or manually, equipped with
lifting straps (Fig. n°6).
Do not expose the package to humidity
or rain (Fig. n°4).
Since the center of gravity is not in the
middle of the package, moving it su-
spended by chords or similar systems
is not advisable (Fig. n°7).

turn the package!! When transporting it make sure that it is firmly held by the four
corners (keeping it parallel to the floor).
All operations must be carried out by
specialized personnel (Fig. n°9).
WARNING!
2.1 - UNPACKING
Remove the straps from the package
(Fig. n°10) and lift the cardboard (h).
The package should be:

detail a);
b) blade extractor (Fig. n°11 detail e);
c) 4 feet (Fig. n°11 detail f);
d) Case, if present (Fig. n°11 detail b).
If it present, check inside the suitcase,
and find the following components:
(Fig. n°11)
1. Instruction booklet (detail d) ;
2. CE compliance certificate (detail c);
3. Audio-visual cassette;
4. Liquid detergent with sprayer;
5. Oil tube;
6. Sharpening and burring grinders;
7. Socket wrench to remove grinders;
8. Grinders
brush;
9. Large and small screwdrivers;
10. Pliers.

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).

2.3 - ELECTRICAL CONNECTION
Check that the data reported on the
technical-part number plate (Fig. n°18),
the delivery documents and the order,
correspond; contact the supplier for cla-
rification if they do not.
At this point make sure that the system
is standard and that the cable and
grounding system perfectly operate.
2.3.1 - Slicer with single-phase motor
The slicer is equipped with a feeding cable with a cross section area of 3x1mm²;
length 1.5m and a “SHUKO” plug. Connect the 230 V. - 50 Hz slicer,
interposing a magnetothermic differential switch of 10A,= 0.03A.
2.3.2 - Slicer with 400 V. three-phase motor
The slicer is equipped with a feeding cable with a cross section area of 5x1mm²,
length1.5m and a red 15A 3F + T CEI plug. Connect the slicer to the 400 V. -
50Hz three-phase supply mains, interposing a magnetothermic differential switch
of 10 A, =0.03A.
2.3.3 - Slicer with 230 V. three-phase motor
The slicer is equipped with a feeding cable with a section area of 5x1mm²; length
1.5m and a blue 15A 3F + T CEI plug.
Connect the slicer 230 V. - 50 Hz three-phase supply mains, interposing a
magnetothermic differential switch of 10A,= 0.03A.
Check that the direction of the blade rotation is counter-clockwise looking at the
slicer from the side of the bladeguard. If not proceed as in par. 2.3.4.
2.3.4 - Blade rotation direction
Check the direction of the blade
rotation with a pulse of the “I” push-
button (ON), immediately followed by
the “0” push-button OFF.
The direction of the blade rotation must
be counter-clockwise when looking at
the slicer from the bladeguard side (Fig.
n°19). In the case that the rotation
direction is not exact, invert (Fig. n°20)

2.3.5 - Electrical connection modification
Unless otherwise specified, the slicers are equipped with 400 V. three-phase
connection. To modify the connection carefully follow these instructions:
-remove the plug from the electric network;
-turn the slicer on the side opposite the trolley;
-take off the yellow cover from the electrical box;
-remove the motor cables from the electronic card;
-connect wires from the motor that have the same colour (white-white, blue-
blue, etc.);
-reconnect them to the electronic card;
-check the positioning of the feed selection plugs on the electronic card (Fig. n°
21);
-close the box, reposition the slicer and proceed as in par. 2.3.3.
