16. 15 ADJUSTMENTS Sealing time (4) Optimal sealing is obtained with the shortest possible sealing time. The parameters that influence the adjustment of the sealing time are: -the production rhythm - the thickness of the material -the type of material. The machine is preset to value 50. Before starting work, or after a period of stopping, perform 2 or 3 empty cycles (without inserting the film or the product) at intervals of approximately 5 seconds. To find the correct time, proceed as follows: 1. Adjust the sealing value to 40 2. Perform 2/3 empty cycles as described above 3. Position the edge of the film on the sealing bar 4. Perform a cycle 5. Has the machine performed the sealing and cutting correctly? YES – the time is correct NO – the time set is too short 6. Return to step 1, increasing the value by 5 unit 7. Repeat the operation until the machine seals and cuts correctly. Hot air temperature (3) It is possible to adjust the temperature of the hot air on the machine. The machine is preset to value 135, any increases in this value must only be made when the machine has reached the operating temperature (signal light goes off), and must always be set back to value 135 before switching the machine off. During switching on and heating, or when the machine is not in use, the thermo regulator functions as a safety thermostat, i.e. it does not allow the heating elem ents to reach excessive temperatures which would shorten their life.

18. 17 MAINTENANCE Before carrying out any operation, deactivate the machine and remove the plug from the power supply, positioning it so that it is immediately visible. Operations to be carried out by the machine operator Cleaning the sealing bar: The machine functions with plastic films and consequently deposits may form on the sealing blade that then cause imperfect sealing. When necessary, remove the residues of film with a dry cloth (made from cotton); carry out this operation immediately after sealing so that the residues can be easily removed whilst still hot. Waste film in the shrink-wrapping basin: Wait until the machine has cooled down sufficiently. If necessary, remove the grille and use a normal vacuum cleaner to eliminate any deposits. Transparent hood and machine body: For the cleaning of the transparent hood and machine body, use a cloth (made from cotton or a synthetic material) dampened with water or a product of the type normally used for cleaning glass.

Before carrying out any operation, make sure that the general switch is on the ”OFF” position, and remove the plug from the socket. LIMITS OF USE The machine must not be used in the followin g locations; open-air environments and/or those exposed to the elements, environments containing steam,fumes corrosive and/or abrasive dusts, environments with fire or expl osion hazards, and in any case wherever the use of fireproof components is required. The electrical equipment operates correctly wi thin anambient temperature range of +5 °C to +40 °C and with relative humidity limits of less than 50% at 40 °C and less than 90% at 20 °C. The machine is not suitable for operation in the presence of ionizing and other kinds of radiations (X-rays, lasers, microwaves, ultraviol et rays). The machine must be stored at a temperature between –5 °C and +55 °C.

13. 12 PRELIMINARY OPERATIONS -Activate the general switch; -Select the desired operating mode by turning the (1) for “sealing only” or (2) “sealing and shrink-wrapping” ; -Check that the temperature display comes on, according to the operating mode selected; -Set the sealing time rotating the wheels; CAUTION: A sealing time of 50 has been set durin g testing and calibration. It is advisable to maintain this setting the first time the machine is started. -Set the value of the desired temperature on the thermo regulator no higher than 145. CAUTION: The temperature has been set to 135 during testing and calibration. It is advisable to maintain this setting th e first time the machine is started. - Wait approximately 7-8 minutes to reach the temperature set, which is indicated by the signal light (led) going off. -Preheat the machine by lowering and raising the transparent hood (20) 2-3 times (applying light pressure during closure); wait approximately 5 seconds between repeats; -Check the position of the grille (21) according to the product to be packaged, so that the sealing is carried out at approximately half its height ; In order to perform this operation, remove the grille, unscrew the supporting feet located in the front part of the basin and screw them back in position in the holes provided at the desired height, then reassemble the grille, resting it first on on e of the rear hooks corresponding to the chosen height.

11. 10 CONNECTION TO THE POWER SUPPLY It is the responsibility of the us er to provide a suitable electrical distribution system (control panel, socket, earth system, etc.) in compliance with the current regulations. In particular, it is advisable to use a differe ntial switch with an inte rvention limit of 0.03 A. The power supply must be appropriate for the mach ine and must comply with the margins set out in the relevant standards. The CEI-EN 60204-1 standards apply in the case of the electrical apparatus of the 4255 ST machines, and consequently the power supply must have a maximum margin of 10% over the voltage value and a maximum margin of 1% in a continuous manner and 2% for a brief period of time over the value of the frequency. The system must be equipped wi th an automatic release system with a differential automatic magnetothermic switch and an earth system that guarant ees the minimum parameters required by the standards, ob serving in any case the speci fic requirements of the current laws in the country in whic h the machine is installed. Before connection, check that the characteri stics of the mains power supply match those indicated on the information plate on the machine. Check that the general switch is in the “0” position. Do not make any “mobile” type connections using extension leads and/or temporary cables, if necessary request the interven tion of trained and qualified staff. Mark the presence of the power cable(s) on the ground if a connection of another type is not possible and the passage of people is expected in the area of installation. Do not leave cables on the ground in the area of vehicle transit. Illumination The machine is equipped with a lighting system. The level of illumination of the room must always be sufficient to avoid areas of shade an d to guarantee operation in maximum safety in relation to the type of activity (use, cleaning, maintenance, etc.).

7. 6 DESCRIPTION AND TECHNIC AL CHARACTERISTICS 4255 ST Wrapping machine Machine for the packaging of products with single-fold sealing film, with dimensions contained in the range indicated in the following paragraphs, with angular sealing of the film and featuring simultaneous cutting or sealing-cutting and shrink-wrapping. Each time that the operator lowers the transpar ent hood the heat of the sealing wire and its pressure against the bottom Teflon-coated edge on the machine body cause the film to melt and the edges to separate, thus creating the packaging. The shrinking of the film can be carried out at th e same time as the cutting and is achieved by the circulation of hot air for ced around the package. THE FOLLOWING ITEMS MUST NOT BE PACKAGED: - loose granular products; - wet products; - liquid and/or gelatinous products if not contained in another package; - highly flammable products; - explosive products; -aerosol cans with pressurized gas, etc.; - anything that could damage the machine or constitute a danger to the health of the operator (for example, acids, corrosive substances, salt). In the case of use with food products, it is advisable to use plastic sealing film suitable for contact with food. In any case, we remind you that the machine is not suitable for contact with food products. PLATES (warning signs and CE mark) The machines are manufactured in conformity w ith the EC Machines Directive EEC 98/37, the Low Voltage Directive (DBT) EEC 73/23 and the successive amendments, the Electromagnetic Compatibility Directive (EMC) EEC 89/336 and the successive amendments.
