The safety guards fulfill a dual purpose:

1. They protect the operator from inadvertent contact with the cutting
tool and the dangerous zone.

2. By lifting up the safety guard the machine stops immediately.
Raising the safety guard even just slightly will stop the machine
from continuing to operate. By closing the safety guard the
machine mustn't start by oneself.

1.4 Safety instructions and information which must be followed

Read the operating manual before operating the machine.

The machine from RONDO is intended for use in the foodstuffs indus-

2

try for the production of unfilled croissants by means of cutting, stamp­ing and rolling-up of dough pieces in thicknesses of up to 7 mm.

However, the machine is not suitable for the processing of other prod­ucts (e.g. modelling clay or other types of mouldable masses which are

not dough products).

Any other use of these units is not in accordance with the purpose for
which they are built. Therefore, the manufacturer will not be liable for
any accidents or damage resulting from unauthorized use; the risk in
any such instance will be borne solely by the user.

Authorized use also means that the user must follow all instructions

prescribed by the manufacturer in respect of operation, maintenance
and service.

Any work on the electrical components of the machine, in particular the
correct professional mounting of the mains plug, may only be carried
out by qualifield personnel who are familiar with the relevant safety in­structions. Defective cables and mains plugs must be immediately re­placed by qualified personnel.

Protective covers over the electrical controls and the mechanical mov­ing parts may only be removed by professionally qualified personnel
and must be remounted before the machine is put back into operation.

Any unauthorized changes made to the machine, and in particular, to
the safety devices on the machine will automatically exclude any liabil­ity on the part of the manufacturer for accidents or damage sustained
as a result of such changes.

Edition BD414202

04.2014

The machine may only be connected to the mains using the mains

Any disposal of the installation must be carried out in accordance with
environmentally-accepted practices. The operators are fully responsi­ble for ensuring that such practices are followed.

The machine may not be operated without the scrapers.

Machine parts located in the areas in which the dough is being pro­cessed, and whose surface coating becomes worn (e.g. chromium
plating), must be replaced.

The machine must never be cleaned using spray water, high-pressure
cleaner, steam-cleaning machine or any similar cleaning methods.

This machine is not designed to be used in explosive ambient.

Prior to the first starting-up, the complete machine must be thoroughly

cleaned.

All still existing protective foils on the machine must be removed.

Defective parts must be replaced with new original parts by RONDO.

After every use, the machine has to be cleaned thoroughly. Not thor­oughly cleaned machines can be a health-hazard for the consumer.

Non-ionising radiation is not intentionally produced but only given off
for technical reasons by electric equipment (e.g by electric motors). In
addition the machine has no strong permanent magnets. By keeping a
safe distance (the distance from the source field to the implant)
of 30 cm, interference with active implants (e.g. pacemakers, defibrilla­tors) can be excluded with a high degree of probability.

If the belt runs off towards one side, proceed as follows:

• Loosen the tension nut on the opposite side

or

• Retighten tension nut on the side where it runs off

• Monitor the belt and, if necessary, correct it until it runs exactly in
the middle of the table

If necessary, repeat this procedure several times. Routinely monitor
the belt during the initial hours that the machine is operational and, if
necessary, correct it again.

Tighten and adjust the conveyor belts with patience!

Prior to carrying out each further correction, allow the machine to run
for at least 30 seconds.

5.5.1 Set-up mode

5.5.2 Normal mode

By pressing the set-up mode key (3), the red LED is activated. On
pressing the start key (1), two rows of croissants are produced. The
croissant roller runs until the stop key (2) is pressed and can be fed
with dough pieces by hand, in order to adjust the rolling-up quality. If
the start key (1) is kept depressed, the machine runs until the start key
is released. The croissant roller continues to run as previously de­scribed.

After switching on the main switch, the machine is always in normal
mode. The red LED is active. On pressing the start key (1), the ma­chine starts up and is stopped by pressing on the off key (2).

5.5.3 Bypass mode

Bypass mode can only be used if the bypass table is fitted to the ma­chine and the plug is connected. No other operating mode can then be
selected. In bypass mode, the selector key 1 croissant roller mode (6)
is activated automatically. In this way the advance rates of the two ma­chine belts are identical. The dough pieces are not separated. By
pressing the selector key 2 croissant roller mode (7), the dough pieces
are separated at the belt change-over point.

5.7 The longitudinal cutting device and the guillotine

Safety guards

The longitudinal cutting device and the guillotine are covered by a

16

17

safety guard.

A defective pneumatic spring (16) on the safety guard must be
replaced immediately! Reason: risk of injuries caused by falling
safety guard.

Function of the guillotine

The dough triangle stamping tool is fitted to the guillotine. The guillotine
is lowered onto the stationary infeed belt by means of a cam. In this
way the triangles are stamped in the dough-band. The guillotine stops

in the upper dead point.

The cutting pressure is set at the factory and should not be adjusted by

the customer.

Adjusting the guillotine

Loose lock nut (17) completely. Remove pressure bar.

19

20

19

Adjust the second lock nut with key SW19. One turn corresponds to
1,75 mm difference in altitude. Turning direction left is decreasing, turn-

ing direction right is increasing the cutting pressure.

Place the pressure bar and fix it with the lock nut (17).

Attention: Adjust by half a turn at maxiumum!

Inserting and removing stamping tools

The stamping tools are designed in such a way that they can only be
fitted to the pressure bar in a certain position. If the stamping tool posi­tion is changed, the functional sequence of the machine is interfered
with.

For insertion, the stamping tool (18) together with the tenon blocks
must be slid up to the stop in the pressure bar and fixed by means of
the star handle (19). Removal of the stamping tools takes place in the
reverse order.

Risk of injury on the sharp cutting edges!

Function of the longitudinal cutting device

The longitudinal cutting device serves to hold the cutting shaft and
presses it with constant force onto the infeed belt. One pneumatic

spring (20) on each side ensures restricted contact pressure in order to

prevent the infeed belt from being cut. A defective pneumatic spring
must be replaced immediately since perfect cutting of the dough-band
cannot be guaranteed.

5.9 Lowering the infeed table

The roller gap can be infinitely adjusted from 0.5 - 5 mm by the roller
adjustment lever (24). The adjusted roller gap is fixed by turning the
star handle in clockwise direction on conclusion. The divisions

0.5 - 5 mm on the scale represent the actual roller gap in mm.

The two additional feed levers (25) serve to adjust the spacing be­tween the upper and lower belt. This allows the rolling-up quality of the
croissants, loose or tightly rolled, to be adjusted.

The divisions of 0.5 - 10 on the scale serve only as guide values and
have no connection with the belt spacing.

If it is necessary to carry out a readjustment, it is recommended to set
both levers to the same value at the outset.

26

26

The infeed table (26) can be lowered when the machine is not in use.
To carry this out the table must be slightly lifted with one hand and the
supports (27) pressed upwards with the other hand. The table can then
be lowered.

The table must be raised for machine operation until it engages in the
working position.
