CONTROL PANEL The buttons on the appliance control panel are as shown in the picture opposite: 1. EMERGENCY STOP PUSH BUTTON.

2. START PUSH BUTTON.

3. FEED CONTROL SWITCH. DESCRIPTION OF THE MACHINE This appliance can be used to sheet all kinds of pastry dough, puff-pastry, leavened pastry, neapolitan puff-pastry etc. The sheeter works quickly and silently and it is fitted with variable speed conveyor belts. Two levers on the side panel of the head, control the direction of rotation for the belts. The dough thickness can be adjusted by a lever. The appliance is also fitted with 2 safety guards that stop the appliance if any of the safety guards are raised. The structure of the appliance is made of electro welded steel plate, the sheeting rollers are chromium plated and the scrapers are coated with anti-adherent teflon. WORK TABLE ASSEMBLY

The following operation must be performed by authorized persons The appliance must not be connected to the mains electrical supply, before fitting or removing the tables.

The working tables must be fitted to the sheeter before operating the appliance. To fit the working tables, push the cylinder pin inside the journal bearing; if necessary adjust the belt for the correct tension. To remove the working-tables, push the table to the opposite side of the machine and remove. The tables are not interchangeable. EXTERNAL PARTS OF THE MACHINE CONTROL PUSH-BUTTONS SAFETY GUARDS Once any one of the safety guards are lifted, a safety microswitch will stop the sheeter. CONVEYOR BELT DIRECTION CHANGING LEVER The joy stick 1 allows the operator to change the direction of the conveyor belt rotation. ROLLER GAP ADJUSTMENT LEVER Move the lever to the right to get the minimum roller opening. Move the lever to the left to move the rollers to their maximum opening position. Use knob 2 to set the position of the lever. SCRAPERS The upper and lower scrapers are hinged and are kept in contact with the cylinder by means of springs and a locking device. The scrapers are easily removed.

INITIAL STARTING AND TESTING The following operations must be carried out by suitably qualified persons.

Testing of the emergency stop push-button: Check that the machine stops, while it is working, by pushing the Emergency Stop Button ‘1’. Checking the Safety Guards: Check that the appliance stops immediately when either of the Safety Guards is lifted. Once the Safety Guard is lowered, the appliance should not re-start. To re-start the sheeter, push the START button ‘2’. Ensure that both Safety Guards are checked. The two micro switches located inside the sheeter will cause the sheeter to stop once the safety guards are lifted. The appliance has been designed to work bread and pastry dough according to the quantities recommended by the manufacturer. Arrange the sheeter in its final working position. If it is the bench model (L50T/70), place it on a suitable work surface. Turn the Feed Control Switch ‘3’ to position 1. Push the START button ‘2’.

The sheeter can be stopped at any time by pushing the Emergency Stop Button ‘1’. To re-start the Sheeter, push the ‘On’ Button ‘2’.

Adjust the roller gap to the thickness required using the lever ‘4’ as showed in the picture. Move the lever to the right to get the minimum roller opening. Move the lever to the left to move the rollers to their maximum opening position. Use the knob ‘5’ to set the position of the lever. NOTE: The cylinders will not work if they are touching each other. L50T/70;- Use the joy stick ‘6’ to reverse the direction of rotation of the belts. L50/08;- Use either the joy stick ‘6’ or pedal ‘7’ to reverse the direction of rotation of the belts. Once the sheeting work has been completed, the working tables can be raised and locked in position to free up space around the appliance.

CLEANING THE SHEETER

ALWAYS ENSURE THAT THE APPLIANCE IS ISOLATED FROM THE MAINS SUPPLY BEFORE COMMENCING ANY CLEANING OPERATIONS

Any dough, which may have stuck on the cylinders, must not be removed whilst the sheeter is operating.

At the end of every working day, clean the scrapers and the conveyor belts, using a plastic scraper to remove build up of hard deposits. Do Not use water jets to clean this sheeter. The scrapers can be removed by unhooking the springs or using the knobs.

MAINTENANCE OF THE SHEETERS During maintenance operations the sheeter must not be connected to the mains electrical supply. The replacement of parts and any repair to the electric system, must only be carried out by suitably qualified persons. If the sheeter is within warranty period, inform the manufacturer.

ELECTRIC PANEL The fuses in the picture opposite are identified with the code ‘FU’ FU1 = Transformer (2F) protection fuse. FU2 = Printed Circuit Board (F4) protection fuse. A copy of the Wiring Diagram is placed in the sheeter electrical compartment.
