Safety equipment
The mechanical and electrical safety equipment is conforming with Directives 2014/35 and 2006/42. The rolling machine is equipped with an NVR device which prevents it from starting up automatically after a power failure. It is equipped with fixed roller guards which, in the PLUS version, can be removed and are fitted with interlock switches which stop the machine when the hand guards are removed.
There are nevertheless “RESIDUAL RISKS” which cannot be completely eliminated, which are highlighted in this manual by the wording “CAUTION”; they are related to the risks of electric shock and crushing when loading and handling the product, as well as when cleaning the machine or using it improperly.

Description
The rolling machine is designed and fabricated specifically to guarantee that:

• all its parts are stable and robustly constructed;
• it is perfectly hygienic, thanks to the careful choice of materials in contact with food products;
• maximum safety during use, cleaning and maintenance operations;
• its operating temperature is in range from 15 °C to 45 °C.

Construction
The rolling machine is made of AISI stainless steel throughout; this ensures that it is hygienic, unaffected by acid and salt, and very resistant to rusting. The pair of PE 300 food safe rollers are driven by a worm screw Gearmotor. The PLUS version has an enamelled AISI 430 stainless steel slide, which is easy to remove when cleaning the machine. A start/stop pedal can also be fitted to it through the provided socket. (PLUS version – optional equipment).

Disposing of packaging
The packaging materials (cardboard box, plastic strap and polyurethane foam) can be disposed of as normal domestic waste; there is no difficulty in disposing of them. If the machine is installed in a country in which special regulations apply, dispose of the material in a regulatory manner.

INSTALLATION

Positioning
Place the rolling machine on a solid table about 80 cm off the ground, with a smooth non-slip surface, keeping at least a 10 cm distance from walls or any other surfaces which may block its ventilation. Keep the machine away from sources of heat and humidity. Remove the protective film – do not use tools which may damage the machine’s surfaces while doing so. Carefully remove all process waste from the machine before using it.

Electrical hookup
The machine has a power cable with a cross-section of 3×1.5 mm², a length of 1.5 m and a 16A Schuko plug. Hook the machine up to the 230 Volt 50 Hz power supply with a differential circuit breaker rated 0.03A. Check that it is properly earthed. Also check that the information on the machine’s nameplate match the specifications given in the delivery and shipping documents and that both the master switch and cable are easily accessible while the machine is in use (see Fig. 7).

USE

Adjustments

CAUTION! All adjustments (adjuster knob and rocker) must be done with the machine shut off. The following adjustments are for illustrative purposes only, since many different variables must be taken into account: the characteristics of the dough, its weight, thickness and form.

Setting the thickness of the dough
This adjustment is done with the plastic knob, by setting the gap between the rollers; once the adjustment is made, the knob can be locked with a pawl. For better results, we recommend adjusting the top and bottom rollers separately.

The thickness is set by rotating the knob (Fig. 10):

• Minimum thickness (0) turn counterclockwise.
• Maximum thickness (6) turn clockwise.

To make the adjustment, pull the knob out towards you (Fig. 11); this engages the spring, allowing you to make the adjustment.

CAUTION! Only run the dough through the rollers once, otherwise it may break up and become sticky.

Setting the rocker
This varies the rotational speed of the dough. Undo the lock screw to change the position of the counterweight and hence the sensitivity by adjusting the position in the rocker’s slot.

• Maximum sensitivity:
  

  • place the counterweight at the centre of the slot;
  • recommended for medium weights (Fig. 13).

• Moderate sensitivity:
  

  • place the counterweight outside the slot;
  • recommended for heavy weights (Fig. 14).

• Minimum sensitivity:
  

  • place the counterweight inside the slot;
  • recommended for low weights (Fig. 12).

Once the adjustment is made, lock the counterweight in position with the lock screw. In order to shape the disk properly, the sensitivity of the rocker must be set to suit the weight of the dough, so that the dough is perfectly horizontal before it passes through the bottom rollers.

CAUTION! Make sure that the rocker, when in the standby position, is always upwards (Fig. 15).

Standard version controls

• START button: starts the cycle.
• OFF button: stops the cycle.

When the machine is running, the led under the controls turns on.

Plus version controls

• START button: starts the cycle. When the machine is running, the green led turns on.
• OFF button: stops the cycle.

Start the machine without dough to check that it is working properly.

CAUTION! The rollers must rotate downwards when viewed from the front.
The machine has been designed for food processing, to roll out flour products with a high water temperature (soft dough) without affecting the characteristics of the product.

Start up
Press the START button; the rollers start to rotate and the machine is ready to use. Before you insert the ball of dough into the opening (the dough must be lightly dusted with flour and risen for at least 6-8 hours), squash the front edge of the ball into a wedge to help it run into the top rollers (Fig. 1-2-3 letter A). Use the adjuster knob to set the gap between the top rollers (Fig. 13). The top rollers flatten the dough into an oval shape; the dough now slides into the rocker and rotates sideways at 90° so that it is ready to pass through the bottom rollers that were previously adjusted to the desired gap (Fig. 2-3 letter B); the disk which comes out of these rollers has a good shape, but must be finished by hand for better results. The 42 RP version does not have the rocker (ref. 5 – Fig. 3); when using this machine, the dough must be moved by hand from the top rollers to the bottom rollers by rotating it at 90° and feeding it through the second set of rollers.

Using the pedal control (PLUS version only)
The pedal control is supplied on request as an accessory for the Plus version. This function must not be confused with the OFF control (Fig. 16 and 17); it is designed solely to limit power consumption to when it is needed. Hook the control pedal up by inserting the cable into the socket on the side of the machine (ref. 7 – Fig. 3).
CAUTION! The machine works properly even without the use of the pedal control.

• Pedal start:
  Press the pedal switch to “O”: the machine does not start running, but waits for the next step. Lightly depress the pedal control: the rollers will start to rotate and the machine is ready for use (Fig. n°18).

• Temporary stop with the pedal:
  Lift your foot off the pedal; the machine will stop. When you have finished using the machine or when you leave it unattended, always press the OFF button (Fig. 16 and 17).

CLEANING THE MACHINE

CAUTION! Before cleaning the machine, pull its plug out of the power socket to isolate the machine completely from the rest of the system.

General information

• The machine must be cleaned with neutral detergents at room temperature, using a soft damp cloth.
• The machine must be cleaned carefully in all its parts, especially those that come into contact with food.
• Do not use a jet of water or a pressure cleaner to clean the machine.
• Do not use tools, scrubbing brushes or anything that may damage the machine’s surfaces.
• Do not wash the machine or any of its parts in a dishwasher.
• Never use non-foodsafe, abrasive or corrosive chemical products when cleaning the machine.

Clean the machine after every use, as required by hygiene regulations in order to keep the machine in good working order.

Use a brush to remove most of the dough and flour residues. Take the two guards and slides off, release the springs, extract the scrapers and turn the adjuster knob so that the rollers are fully open. Carefully clean the machine and all its parts, including those you have disassembled, using a sponge or cloth with water and detergent. Now rinse off all traces of detergent. Dry the machine and its parts with foodsafe paper towel, then wipe over all parts that come into contact with food and the machine as a whole with a clean cloth soaked with food processing machinery disinfectant.

CAUTION! The PLUS version has an AISI 430 ceramic coated slide which is held in place with magnets so that it is easy to remove for cleaning; it is easier to remove the scrapers once the slide has been taken off. The hand guards are equipped with handles for easy removal.

Maintenance
Before you use the machine, always check that it is perfectly clean in all its parts, especially those that come in contact with dough. Clean it as described above, if necessary.

Lubricating the shafts and rollers
The shafts and rollers must be lubricated once a year.

• Remove the plexiglass guards, slides, springs and scrapers, then undo the screws holding the back panel and mounts in place.
• Extract the rollers and their couplings, then clean them carefully with a sponge with neutral foodsafe detergent and hand warm water.
• Rinse them off and dry them with paper towel. Now lubricate the shafts and the holes in the rollers with paraffin oil.
• Restore and secure all parts in reverse order with respect to removal.
