4.3 INSTRUCTIONS FOR CONNECTING THE TUBE FROM THE
PUMP TO THE CONTAINER
• Insert the half-pipe fitting in the tube, blocking it with a suitable
hose clip on the outside (FIG.15/A). Then connect everything to
the pump with the clamp provided (Fig.15).
Use spiralled pipes in PVC suitable for drinkable liquids, so as to
avoid obstructions caused by bending or squashing. Fix the other
and of the tube to the container designed to receive the marc,
making sure that the extremity of the tube is always clear and that
it is not submerged into the liquid itself (Fig. 16-17).
4.4 ELECTRICAL CONNECTIONS (SEE ELECTRICAL
DIAGRAM PAR.7
All electrical connections and checks must be carried out by a qualified electrical engineer.
Before carrying out any work, check that the mains power supply and frequency available corresponds with
those given on the plate near the motor. Check that lead with which the machine will be connected to the
mains (and any eventual extension cord) is capable of the maximum absorption current (see par.2.6).
Check that the earthing system in the cellar and in the mains is in perfect condition.
On the mains supply cable to the motor use a plug which conforms to safety standards and is of suitable
amperage. The green/yellow wire is the earth wire. The plug can be connected to a suitable
extension cord in turn connected to the mains, provided there is a lifesaving, differential, automatic circuit
breaker switch.
(This is especially important since cellars are usually damp places and the floors around the machine may
often be wet).

5.1 STARTING UP AND OPERATING INSTRUCTION
Check that the machine is stable after positioning it on a level floor, after which block the front wheels using
the brackets provided (FIG. 3 position 16). The operator should position himself on the side where the
protective part is lower and should make sure that he is the only person to feed the machine. According to
the type of mains supply, the operator should start the motor as follows:
MONOPHASE ELECTRICITY SUPPLY:
• Make sure the "Stop" button is off. If is not, rotate the round switch a 1/4 of a turn and it will automatically
come onto the off position.
• Push button 1 keeping it pressed for about 2-3 seconds (take-off torque) then release and the machine will
now be working (Fig. 18).
TRIPHASE ELECTRICITY SUPPLY:
• Make sure the "Stop" button is off.
• Push button 1 then release it.
• The machine is now working.
Check that the direction of the rotation is correct. If not, remove plug, open it and exchange the position of
the two phase wires. Reassemble everything, after which the may begin (Fig. 18).
To stop the machine press the "Stop" or "Emergency" button.
At this point the machine is working, so you can proceed and load the grapes into the feeder hopper (Fig.
19). Never use the machine without the upper guard (Fig. 20).
While working check that the grape stalks do not obstruct the exit point completely: at regular intervals,
remove them using a harpoon or garden fork (Fig. 21).
WARNING: never do this operation with your hands (Fig. 9), and ensure that no one else does this operation
unaware of the dangers. When the machine is in movement, the operator must not reach inside the feeder
hopper with his hands (Fig. 7).
When there are no more grapes and the work has ended. to clean the inside of the machine from eventual
residues, switch off the motor and with the help of a brush push to re-start it, return the switch to "O" and
repeat the starting sequence.
When it is necessary to stop the machine suddenly, press the emergency button placed on the motor (Fig.
18). To start up again reset the emergency button.
5.2 POSSIBLE PROBLEM AND CURES
For any eventuality other than the ones described below, you must request assistance from a qualified
technical engineer, or directly from your area dealer.
LOSS OF MUST AND GRAPE SKIN AT THE GRAPE STALK EXIT POINT
While working, it may happen that at the grape stalk exit point, as well as grape stalks, some grape skins and
must could also come out.
This indicates that the machine is clogged up.
The possible causes are:
• a loss of revs by the pump caused by a loose bet (this can also be noticed by the smell of burning rubber).
Proceed as follows:
• switch off the motor and remove plug from mains
• remove the lower guard (Fig. 3 position 10) and check that the belt is tight. If necessary, adjust by
operating the adjusting screw placed under the motor's shelf support ( Fig. 3 position 12);
A LACK OF LIQUID WITHIN THE GRAPES (VERY DRY SEASONS).
The pump finds it difficult to push the liquid along the tube, lowering considerably it's carrying capacity and
thus clogging up the machine. Proceed as follows:
• switch off the motor

8
• remove the tube from the container and lower it to the ground placing a bucket at the end of the tube
• re-start the motor and put some must in the feder hopper
• wait for the mare to carne out in a more liquid form than before, then stop the motor once again
• replace the tube in its normal position, re-start the machine being careful to add., from time to lime, some
must to the other grapes.
ENTERY OF FOREIGN BODIES INTO THE MACHINE
Entry of foreign bodies caused loud noises and vibrations and can also cause serious damage to the
machine (e.g. scissors or knives used for the harvest of grapes end left in the baskets).
Proceed as follows:
• press the emergency button as soon as possible
• remove plug from the mains
• empty the upper feeder hopper
• open up the machine (par. 4.2) and remove the foreign body
• remove the hold at the grape stalkes exit point, remove the grille and check that it has not been damaged
• carry out any necessary repairs. If spare parts are needed, ask at your area dealer.
Check that the foreign body has not reached the pump. If so, dismantle as follows:
• remove the lower guard (Fig. 3 position 10)
• remove the stay-rod of the feeder hopper flap, remove the pins or screws of the feeder hopper's hinges
then put aside the upper frame
• detach the tube from the pump, being careful not to let the marc still in
the pump and tube drip
everywhere (Fig. 22)
• wash and clean the lower frame, then remove the belts
• using a pin-removing tool, remove the elastic pin which holds the pulley
(Fig. 23-A) and remove the pulley
• remove the segeer Ø 25 from the axle (Fig. 23-B)
• remove the pump fixing screws (Fig. 23-C), detach the pump from the
chassis together with
the axle (Fig. 24)
• slide out the pump from the axle (Fig. 25) and check the condition of the
pump and of the impeller (repair or replace as required. To remove the
impeller, first remove the elastic pin (Fig. 25-A).
• once everything has been repaired, replace the axle into the chassis,
being very careful to replace the end opposite the pump in its proper seat
within its support
• clean the head where the pump rests. Take some silicone suitable for
alimentary/uses and pour a small quantity along the centre line of the
pump's fixing holes (Fig. 26)
• clean the surface of the pump and re-assemble
