Usage Features:

The V 235 NC is designed for cutting wood and plastic profiles. It features a vertical feeder system that can be adjusted for different types of profiles. The machine includes various safety features to ensure operator protection.

• Setting the Feeding Unit: The feeding unit can be adjusted by lifting the manual feeding cylinder, unscrewing and positioning the screw and limiter, and then tightening the screw.
• Setting the Collecting Guides: The collecting guides can be adjusted by loosening and setting the guides, maintaining a gap of about 1.5 mm, and then blocking the levers.
• Setting the Pile Pressure: The pile pressure is set from the computer's "BASIC MENU" by selecting "Manual." The arrow keys are used to select "Insert piece" mode and press "Start." The number of pieces to collect is then entered. The screws are loosened and the pressure cylinder is set so that it presses only the upper slat, leaving the bottom one free. The arrow keys are used to select "Block piece" mode. Press "Start" again to check the effectiveness of the blocking.
• Aligning the Piece: The nuts are unscrewed and the roll is positioned so that it does not press against the upper edge of the piece. The nuts are then put back on.
• Inclination of the Collecting Guides: The collecting guides can be inclined by loosening the screw and adjusting the guide to ensure orderly and correct distribution of the elements.
• Inclination of the Feeding Unit: The feeding unit can be inclined by lifting the manual feeding cylinder, unscrewing the screw and setting the limiter. The spacing between the H positioning must correspond to the width of the element. The limiter is then tightened. The clamping lever and screw are unscrewed and set at the 90° angle to the collecting guide.
• Pneumatic Board: The pneumatic board controls the pneumatic cylinders. The pressure of the aligning guide clamp is about 2 bars. This value is set during production. If there are clamps on the profile of the frame, the lower the pressure by means of the regulator.
• Photofeeder (optional): The photofeeder is used to position the piece. The left and right photocells must be positioned in line with the feeding tape. If they are positioned too low, they will read the tape; if too high, they will fail to read the passage of pieces of small dimensions. The positioning of the photocells is checked periodically by means of the respective diodes. The diodes should remain lit and go out at the moment when a passing element impedes the photocells' reciprocal refraction.

Maintenance Features:

Regular maintenance is crucial for the longevity and optimal performance of the OMGA V 235 NC.

• General Maintenance:
  • The vertical feeder does not require any particular maintenance.
  • For the good functioning of the machine, it is recommended that it be kept in general cleanliness using compressed air or a dry brush.
  • The photofeeder does not require any particular maintenance.
• Daily Maintenance:
  • Clean the presence sensor.
  • Lubricate periodically, with a small amount of oil, the rod of the positioning cylinder.
  • Check periodically the positioning of the photocells by means of the respective diodes.
• Periodic Maintenance:
  • The expected duration of the machine in conditions of normal use and regular maintenance is 10 years.
  • After the operating activity of the machine ends, it can be disposed of in a regular scrap yard and industrial waste disposal center.
  • It is necessary to carry out a periodic check of the safety devices and verify the efficiency of the V 235 NC line.
  • Replacing the Blades:
    • Do not let the flange fall after removing the screws; it is recommended that it be put in a safe place, cleaned carefully from all the remaining dust, resin and/or greasy stains.
    • Get hold of the blade with both hands and delicately remove it from its place outside and slightly to the left, as indicated by the arrow. This movement, which covers it in part, does not impede that in any way.
    • Put aside the blade wrapped in thick packing paper, which protects from cutting oneself and others.
    • Clean carefully (removing the grease) the surface of the manrel; don't use abrasive products or metal.
    • Replace the blade and check the direction of rotation.
    • Replace the external flange.
    • Using the two wrenches, tighten the screws holding the manrel.
    • Close the cover tightening well the screws.
  • Replacing the Belts:
    • Remove the rear sump.
    • Ensure that the operative unit is in the rest position and mechanically fixed (the procedure is illustrated and described on pages 19 and 20). The obligation to carry out this procedure is also signaled by the relative plate (consult the "Safety markings" chapter).
    • Remove the screws.
    • Loosen the screws and raise the engine to remove the belt. Before mounting the new belt, clean the surface of the pulley well; don't use chemical solvents or abrasive products but a damp cloth lightly soaked in alcohol.
    • After replacement, lower the engine to tension the belt and tighten the screws.
    • Tighten the screws.
    • Re-mount the rear sump.
    • It is absolutely necessary that the operator releases the operative unit from the mechanical block. Forgetting this procedure would lead to serious damage to the machine structure with a consequent jeopardizing of its correct functioning.
• Troubleshooting:
  • In case of emergency, press one of the buttons (7 or 9). Using the emergency button disconnects the machine from its electric source (the pneumatic source is disconnected manually by the operator acting on the filter out of the lubricating reducer).
  • Having removed the cause of the emergency, it is necessary to re-arm the button to restore normal working conditions.
  • The re-arming of the emergency button maintains the system in conditions of rest so that re-starting of the machine is possible only through a voluntary command of the operator.
  • The machine is guaranteed for a period of 12 months starting from the date of the purchase invoice. It consists of a free of charge replacement of all mechanical parts showing material or manufacturing defects.
  • The warranty period for all electrical and electronic components is limited to a period of 6 months.
  • The warranty does not cover breaks or defects arising out of external factors, maintenance mistakes or other causes. Improper use of the machine, use of the machine overloaded, normal wear, assembly mistakes which we may not be held responsible for, replacements not supplied or defects in delivery of components is ex our works.
  • The machines must be returned on a free port basis, even when covered by the warranty. To make use of the guarantee, offered by DIERREGI S.r.l., it is necessary to supply the following information: Machine model, Serial number, Volts & Hz of the machine, Name of the dealer from which the machine was purchased, Description of the defect found, Description of the type of operation carried out, Working ours per day. In the case that the data above mentioned is missing even partially it cannot be taken into account.
  • The machine has been constructed in accordance with the essential safety requirements Directive 2006/42/CE. Parts must be replaced using suitable spare parts provided by DIERREGI S.r.l. only. The use of replacement parts other than those supplied directly by DIERREGI S.r.l. is prohibited. The use of parts not supplied by DIERREGI S.r.l. or failure to adhere to the maintenance procedures described in this manual will automatically release DIERREGI S.r.l. from any liability.
  • All of our machines are submitted to testing in the factory. Any damages discovered while unpacking must be immediately reported to the carrier. Furthermore, check that all accessories and options that are cited in the packing list are present.
