1. LIFTING THE PACKAGED MACHINE

The machine is transported on a wooden pallet A,

secured by a cross bar C, and fastened to the pallet by

means of two threaded rods B.

To lift by means of a pallet transfer unit or lift truck,

insert the forks in the positions indicated in the figure.

Before lifting, check the suitability of the equipment.

NOTE:

The material used for packaging, apart from the threaded

rods and the bar, can be recycled or disposed of as

urban waste.

2. LIFTING THE UNPACKAGED MACHINE

By means of a belt

Positioned between the column and the end of the tool

holder shaft, as shown in the figure.

It is advisable to use a suitable space bar (e.g. a

wooden plank with a minimum section of 25x130 mm)

in order to keep the belt away from the cover so that

it is not damaged.

As the machine is decentred with respect to the point

of suspension the machine hangs in an off-balanced

position. In no way, however, does this effect the

safety of the operators or the machine.

NOTE:

Avoid oscillations during this operation.

By means of a lift truck

Insert the forks in the positions indicated.

Lift carefully keeping the forks in a horizontal position.

B.3 INSTALLATION –PREPARATION FOR COMMISSIONING

•The machine must be positioned in an area which is suitable for working with

foodstuffs and that can be thoroughly cleaned.

•It is not necessary to fasten the machine to the ground; however it must be levelled

by adjusting the front feet which at the same time lifts the front wheel from the floor.

•Check that the electric line is correctly connected by means of an approved plug.

•Check all the commands and that the mobile guard protection microswitch is

functioning correctly. Adjustment is carried out by the manufacturer.

The user must contact the authorised technician if adjustment is required.

•Before commissioning, check the maximum quantities of the product to be loaded into

the bowl, by consulting the tables in Chapter B.1 relevant to the model purchased.

B.4 NORMAL AND SAFETY SHUTOFF

1. NORMAL SHUTOFF

•In manual mode: Stop the machine by pressing the machine shutoff push

button.

•In automatic or semiautomatic mode: The machine is automatically shutoff by

the timers.

2. SAFETY SHUTOFF

•The machine shuts-off whenever the mobile guard is lifted from the bowl.

•NOTE:

In all cases rotation is stopped, even if gradually, in less than 4 seconds.

3. MOVING THE MACHINE BY HAND

The machine may need to be moved in order to clean the area

under it.

To move the machine :

Tighten the threaded rod of the foot Cwhich when it retracts allows

the front pivoting wheel B to touch the floor. The other two points

of support are the two rear fixed wheels A.

Caution:

•Disconnect the feed cable Dbefore beginning the procedure

described above.

•After returning the machine to its original position, ensure its

stability by loosening the two threaded feet C thereby raising

the front wheel B from the floor

•To power the control panel, activate the general switch E.

B.5 CONTROL PANEL

1Timer for first spiral tool speed

6Timer for second spiral tool speed

When the pointer is below zero, (display unlit), the timed shutoff

function is deactivated.

The LED, bottom right, when lit indicates whether the reading scale

is in seconds (s), minutes (m) or hours (h). To change the scale

consult the qualified technician.

2Start push button for first spiral speed

Does not function with the bowl cover open.

It permits three types of functions:

•MANUAL WORK MODE IN FIRST SPEED

(Timers 1and 6deactivated)

Shutoff by pressing stop push button 5.

•SEMIAUTOMATIC WORK MODE IN FIRST SPEED

(Timer 1activated, 6deactivated)

Shutoff is controlled by timer 1.

•AUTOMATIC WORK CYCLE

(Timers 1and 6 activated)

The following sequence is carried out automatically:

1. Timed work phase in first speed.

2. Bowl stops for 2 seconds.

3. Timed work phase in second speed.

4. Automatic machine shutoff.

3Power indicator

When lit, it indicates that the electrical board is powered.

4Bowl jog rotation command in first speed

Also functions with bowl cover open.

When the push button is released the bowl stops rotating.

5Machine emergency/stop push button

Interrupts all modes of rotation.

NOTE

If the cover is lifted while the machine is running, the machine shuts off, but

the timers memorise the actual time reached. Once the cover has been closed

again and the start buttons 2 pressed, the machine restarts and the timers

permit the rest of the work cycle to be completed.

This memory is not stored if the machine is shut off by means of stop push

button 5.

manufacturer or by one of his direct resellers. In the event that the user

has specially trained personnel at his disposal, once the warranty has

expired, he can request the manufacturer provide him with more detailed

drawings and lists, as well as exploded views of the mechanical parts. In

this case the user is responsible for any damage caused to persons and/or

the machine.

After 2000 working hours: it is advisable to have a technician inspect the

bearings and the other transmission parts.

5. If necessary adjust the belt tension:

•To increase the tension:

Loosen the two nuts C.

Tighten the two nuts B.

•To decrease the tension:
