1.3.1 USE

The mod. «IRIS» dough mixer has been

exclusively designed for the use of mixtures of

various types of flour available on all the

international markets, in authorized work

environments and small industries such as:

bakeries, pizza restaurants and confectioners’

shops.

1.3.2 DESCRIPTION

(The numbers between brackets refer to Fig.1).

The machine mainly consists of a robust metal

bearing structure (10) equipped with two drive

units: an upper one (14), which turns the dough

tool. and a lower one (15), which drives the

bowl (18). The rotational movement of the IRIS

30-40 dough mixer is controlled by a single

motor. The electric panel is situated under the

upper cover, which also closes and protects

the machine. In both the drive units, the actual

drive is transmitted by V-belts, the tension of

which is regulated by belt stretchers. The

dough mixer’s functions are controlled by a

control panel (3), which is described in section:

«4.1.1 Control panel».

The work cycle can be programmed by means

of two timers, which allow the dough mixer to

automatically switch from the first to the second

speed. The bowl can be turned at first speed by

means of a selector, i.e.: NORMAL (anti-

clockwise direction), REVERSE (clockwise

direction), or bowl at a standstill. Drive reversal is

not available for version 30-40, thus the relative

selector is not installed. During the first phase,

the ingredients are mixed together so as to obtain

a homogeneous dough. As the consistency of the

mixture and the speed of the dough tool increase,

the dough is finished and fully blended in the

second phase. At the end of the process, the

operator can switch the selector to the reverse

rotation position (opposite to the direction of the

normal cycle, i.e. clockwise) to detach the dough

from the dough tool while bringing it to the center

of the bowl so that it can be easily cut and

removed.

WARNING

The Manufacturer declines all liability for

direct and indirect damages to persons,

animals or property caused by the machine

having been used for purposes other than

those described in this manual (see 1.3.2

Use).

1.3.3 SAFETY DEVICES

WARNING

The electrical system of this machine has

been built in compliance with the current

standards, particularly standard EN 60204-01.

The electrical system is equipped with a device

that protects against overloads and includes a

thermic relay and protective fuses (consult the

wiring diagram supplied separately).

To safeguard the operator, the grille (4) prevents

the limbs from accidentally accessing the bowl

interior when the dough tool is turning. The bowl

and dough tool will immediately stop if this grille is

raised when the machine is running. The electric

panel is also protected by a key-operated lock. In

versions 80-250, the access door has a key-

operated lock (9) and a main switch (20) with

that the lifting and handling means used are

in perfect conditions and fit for the job; do

not touch hanging loads and keep at a

safety distance away; the loads must not be

raised more than 20 centimeters from the

ground when they are transported. Make

sure that the work area is clear and that

there is an «escape route», i.e. a safe, free

area that can be rapidly accessed to the

operators should the load drop. To prevent

the load from shifting, the surface on to

which the machine is loaded must be

perfectly horizontal.

Once the machine has been transferred to the

means of transport, make sure that it remains

well locked in position and is unable to move.

Fix it firmly to the surface on which it has been

placed using taut ropes to prevent it from

shifting in any way.

the ON position

2) Lift the protective grille (4 Fig. 1) to

immediately stop the motors.

3) Now start to remove the dough.

The button (6 Fig. 7) allows the operator to

turn the bowl continuously or intermittently

and to access the part with the dough in

an easier way.

After this and if there are no other operations

to carry out, stop the machine in the

following way:

- press the red stop button (2 Fig. 7);

- turn the switch on the machine (Fig. 8) to

the OFF position;

- disconnect the machine from the electric

power source by means of the main switch

on the electricity main, prior to the

machine itself.

4.3 EMERGENCY STOP

Whenever the operator decides that the

machine must be blocked and prevented from

operating, he can raise the protective grille or

press the EMERGENCY button (red) on the

control panel. This latter action deactivates

the electric power supply.

4.4 CLEANING AFTER USE

WARNING

Disconnect the machine from the electric

power source before beginning to clean

the machine.

Remove any wet or dry residues and flour

dust with a slightly damp cloth.

WARNING

Never use continuous jets of water and

avoid splashing water indirectly in order

to clean the floor around and under the

machine. Once a month, remove the cover

and clean off the dust and residues from

the transmission with a vacuum cleaner.

Once the dough making and cleaning

operations have terminated, always make

sure that the electric power source has

been disconnected.

SECTION 5

Maintenance

5.1 ROUTINE MAINTENANCE

This range of dough mixers with fixed bowls

does not require any particular maintenance

work. However, tip-top performance and a

perfectly efficient machine are only obtained by

methodic and regular compliance with the

following regulations.

WARNING

The servicing, adjusting and preparation

jobs must always be carried out when

the machine is off and disconnected

from the electric power source.

- Maintenance work and adjustments may

only be carried out after the electric

power source has been disconnected by

turning off both the mains circuit-breaker

and the machine’s main switch (Fig. 8).

The routine maintenance operations can

be carried out by the operator, while

more complex jobs must be done by

specialized and authorized personnel.

- The general condition of the machine

must be inspected and the machine itself

cleaned daily, or as frequently as

possible.

- Excessively worn or broken parts must

be replaced immediately.

- The wiring diagram, which is supplied

together with the machine, must be kept

with care and consulted whenever

necessary. As soon as the machine is

received, it is advisable to make a copy

of the diagram and keep it with the other

documents.

5.2 BELT TRANSMISSION

The belts normally wear in an almost uniform

way, even though this wear may take place at

different times in one transmission as regards

the other and is bound to the consistency of the

dough as well as the number of hours that the

machine is used each day.

Every so often, the operator must therefore

check the degree of wear on all the belts in the

machine. Remember that if replacements are

required, the Manufacturer recommends

replacing all the belts at the same time

(complete replacement of each set of belts).

5.2.1 DOUGH TOOL TRANSMISSION

If the dough tool seems slow to turn, the

transmission belts may have loosened or be

broken. Proceed in the following way to

adjust and/or replace the belts:

1) Using a pipe wrench, unscrew the central

nut that fixes the cover to the machine (2 Fig. 1).

Raise the cover, paying particular

attention to the electric cables of the control

panel, which cannot be detached.

2) Loosen the four screws (1 Fig. 9) at the

base of the belt stretcher. Use the screw of

the belt stretcher (4 Fig. 9) to adjust the

tension of the transmission pulley/dough tool

belts.

4) Loosen the four screws (3 Fig. 9) on

the motor bearing plate. Use the screw of the

belt stretcher (4 Fig. 9) to adjust the tension

of the motor pulley/transmission belts.

5) Retighten the four screws (3 Fig. 9).

6) Fit the upper cover back in place and

fix it with the relative nut (2 Fig. 1).

To replace any broken belts, remove the

cover and loosen the four screws that fix the

belt stretcher, as described previously, then

replace the broken belts. Always refer to the

spare parts tables which show the location of

the various different components. At the end

of the operation, tighten the belts in the

correct way and fit the upper cover back in

place.

5.2.2 BOWL TRANSMISSION

If the bowl seems slow to turn, the

transmission belts may have loosened or

be broken. Proceed in the following way to

adjust and/or replace the belts:

1) Turn the belt tightening knobs (24 Fig. 1)

positioned at the base of the machine (2

knobs in models 80-250, 1 knob in models

30-40).

To replace any broken belts, first loosen them

with the two knobs (24 Fig. 1), remove the

side inspection panel (8 Fig. 1), then

replace the broken belts. Always refer to

the spare parts tables which show the

location of the various different

components. At the end of the operation,

tighten the belts in the correct way and fit

the side inspection panel back in place

with the relative four screws.

5.3 STORAGE

If the machine is to remain idle for a long

period of time, it must first be thoroughly

cleaned, the parts liable to wear must be

lubricated and the entire machine covered

with a plastic cloth.

If these operations are carried out with care, it

will be all to the advantage of the user, who

will find the machine in an excellent condition

when it is required for use once more.

Comply with the laws in force in the country

where the machine is used when it comes to

the way the products used for cleaning and

servicing the machine are used and disposed

of. Also comply with the recommendations of

the manufacturers of such products.

WARNING

If the machine is dismantled, comply with

the anti-pollution laws in force in the

country of use.
